Terms of Service

Effective August 29, 2026 · Version 1.8

Terms of Service

Effective Date: August 29, 2026 Version: 1.8

These Terms of Service ("Terms") govern your access to and use of the Synergy In Construction (SynC™) platform, website, and related services (collectively, the "Services") provided by Synergy In Construction, LLC, a Florida limited liability company. By accessing or using the Services, you agree to be bound by these Terms. If you do not agree, do not use the Services.

1. Acceptance of Terms

By creating an account, accessing, or using the Services, you confirm that you have read, understood, and agree to these Terms and our Privacy Policy. If you are using the Services on behalf of an organization, you represent and warrant that you have the authority to bind that organization to these Terms, and references to "you" will refer to both you as an individual and the organization.

2. Eligibility

You must be at least 18 years old and capable of forming a binding contract to use the Services. By agreeing to these Terms, you represent and warrant that you meet these requirements and that your use of the Services complies with all applicable laws and regulations.

3. Account Registration and Security

3.1 Account Creation

To access certain features, you must create an account by providing accurate, current, and complete information during registration. You agree to update such information promptly as needed to maintain its accuracy.

3.2 Account Security

You are responsible for:

  • Maintaining the confidentiality of your account credentials
  • All activities occurring under your account
  • Notifying us immediately of any unauthorized access or security breach
  • Using a strong, unique password for your account

3.3 Account Termination

We reserve the right to suspend or terminate accounts that violate these Terms, are inactive for extended periods, or pose security risks.

4. Description of Services

4.1 Core Services

SynC provides a cloud-based platform for construction project management, including but not limited to:

  • Project specification management and standardization
  • Equipment datasheet repositories and management
  • Collaboration tools for construction teams
  • Document version control and revisioning
  • Project distribution and sharing features
  • Company profiles and discovery

4.2 AI-Powered Features

The Services include artificial intelligence and machine learning features, including but not limited to:

  • AI-assisted specification writing and analysis
  • Automated content suggestions and improvements
  • Natural language processing for construction documents
  • Predictive analytics and recommendations

These AI features utilize third-party AI services and APIs. By using AI features, you acknowledge that:

  • AI-generated content may contain errors or inaccuracies
  • You are responsible for reviewing and verifying all AI-generated content
  • AI responses are not professional advice (legal, engineering, or otherwise)

How content is transmitted to those third-party services, and the limits on what they may do with it, are addressed in §5.3.3.

4.2.1 Your Conversations with the AI Assistant

Your conversations with the AI assistant are stored by the Services so that a conversation remains available to you after you close it, rather than existing only for as long as the page is open. The messages you send to the assistant are your User Content under §5.1, and §5.3 applies to them.

  • A conversation is your own record and is private to you. The Services provide no means by which another user can view a conversation of yours, and conversation content is not included in any published document, revision record, or export of project content. A conversation of yours is retained for you even where you later cease to have access to material discussed in it.
  • Conversations are retained for a stated period and are then deleted automatically. The period, how it is measured, and what it does and does not cover are stated in our Privacy Policy, which is the authoritative statement of them; these Terms state no period of their own.
  • You may delete any of your conversations at any time, and you may copy one out of the Services as readable text. Deletion through the Services takes effect immediately.
  • We limit the number of conversations stored for you and the length of a single conversation. The Privacy Policy describes these limits and what happens when one is reached.

4.3 SynC Standards Wiki

The Services include a collaborative wiki ("SynC Standards") where authenticated users may contribute to, edit, and improve construction reference specifications. SynC Standards are governed by the additional terms in Section 5A below.

4.4 Third-Party Integrations

The Services may integrate with third-party platforms and APIs. Your use of these integrations is subject to the third party's terms of service and privacy policies. We are not responsible for the availability, functionality, or security of third-party services.

4.5 Beta and Preview Features

The Services are under active development, and we may make certain features available on an alpha, beta, preview, pilot, or early-access basis ("Beta Features"), whether or not labeled as such. Beta Features are provided for evaluation purposes; they may be modified, suspended, or discontinued at any time without notice, may be subject to additional usage limits, and may contain errors or produce unexpected results. Beta Features are provided "AS IS," are excluded from any availability or support commitment, and your use of them is at your own risk. Feedback you provide on Beta Features is governed by Section 8.5.

5. User Data and Content

5.1 Your Ownership

You retain ownership of all data, content, specifications, designs, documents, and other materials you create, upload, or submit to the Services ("User Content"), except as otherwise provided in Section 5A regarding SynC Standards contributions and the use of SynC Standards within projects (Section 5A.7).

5.2 License Grant to SynC

By uploading User Content to the Services, you grant SynC a worldwide, non-exclusive, royalty-free, transferable license to:

  • Store, process, and transmit User Content to provide the Services
  • Display User Content to authorized users within your organization or projects
  • Create derivative works as necessary to provide the Services and to operate them as described in §5.3
  • Back up and restore User Content for data protection purposes

This license exists only for the duration of your use of the Services and for a reasonable period thereafter to fulfill backup and legal obligations.

5.3 Limits on Our Use of Your Content

Beyond delivering the Services to you, and the legal and business disclosures described in our Privacy Policy, this Section states the only ways SynC uses User Content. It is a limit on our rights, not a grant.

5.3.1 We Do Not Use Your Content as Training or Research Material

We do not use User Content, or any adaptation or excerpt of it, to train, fine-tune or improve any generative artificial-intelligence model, or any general-purpose or foundation model, whether our own or a third party's, and whether or not it has been anonymized, de-identified or aggregated. We do not license, sell, publish or otherwise disclose User Content to any third party for those purposes.

Removing names or other identifying details from a specification does not change its confidential status. De-identified User Content remains your confidential information, and a project specification remains your confidential work product under §5A.7.2.

This Section applies to all User Content, whenever submitted, including content submitted before this version took effect.

Operational models. We may build and use models that classify, score, match, rank, or detect anomalies in content within the Services — for example, identifying what kind of value a datasheet field holds, flagging a likely duplicate, or detecting an entry outside its normal range. A model of this kind falls outside the prohibition above only if all of the following are true:

  • it produces classifications, scores, labels, rankings or similar structured outputs, and does not generate natural-language or free-text output;
  • it is used only to operate the Services, and is not distributed, licensed, sold, or otherwise made available outside them; and
  • neither the model nor its outputs reproduce, or disclose the substance of, your User Content to any person not already authorized to see that content.

Where such a model is developed using content from more than one customer, we use it only to operate the Services, and never to disclose one customer's content, or any excerpt of it, to another.

Exception by written agreement. We may use your User Content in a way this Section otherwise prohibits only under a separate written agreement that you execute and that identifies the content and the use. Your acceptance of these Terms is not such an agreement, and we will not require such an agreement as a condition of providing the Services to you.

This Section does not restrict:

(a) Content you offer for inclusion in the SynC Standards library. If you submit content for the purpose of having it included in a published Standard — for example a suggested change containing proposed text — that submission is a Contribution governed by the Contributor License Agreement, not by this Section. Consistent with that Agreement, whether something is a Contribution turns on the purpose for which it was submitted — content offered for inclusion — and not on the channel used to submit it.

Content you write inside your own project for your own project's participants is not a Contribution, and does not become one because it concerns a Standard you imported.

(b) Feedback you direct to SynC, including a report of an error in a published Standard, which is governed by §8.5.

(c) SynC Standards content as published in the public SynC Standards library, which is licensed under CC-BY-SA 4.0. This does not permit us to read that content out of your private project.

(d) The usage and structural statistics described in §5.3.2.

5.3.2 Usage and Structural Statistics

We collect and analyze how the Services are used, and structural measurements derived from content, in order to operate and improve the Services. This includes counts, frequencies, distributions, timings, error rates, and feature-utilization patterns — for example, how many datasheets a project contains, how often a value is deferred to the drawings, how often a publish is blocked because a component is out of date, or how frequently a given field name appears across the platform.

These are measurements about content. They do not include, and may not be used to reconstruct, the text of your specifications or any other User Content. Where a statistic could identify an individual customer, we report it only in aggregate.

5.3.3 Processing by Our Service Providers

Delivering AI-assisted features and search requires transmitting the content you are working with to service providers that perform inference and text-embedding on our behalf. We do not permit those providers to retain your content for their own purposes or to use it to train their models. We enforce this by technical configuration rather than by a direct contract with each host: requests are restricted to inference hosts we have vetted, hosts identified as retaining or training on submitted content are excluded from serving them, and a request fails rather than proceed if no host satisfies those constraints. Those hosts are suppliers of the routing service we contract with; we rely on that configuration and on each host's published data-handling terms.

Which providers we use, where they process content, and the specific controls we apply are disclosed in our Privacy Policy and on the subprocessor list it references, and they change from time to time. We may change providers, hosts or mechanisms. If a change materially reduces the protections described in this Section, we will give at least thirty (30) days' notice under §18.2 before the change takes effect.

If your engagement requires zero-data-retention processing or a restricted set of processing jurisdictions, contact privacy@synergyinconstruction.com.

5.4 Representations and Warranties

You represent and warrant that:

  • You have all necessary rights, licenses, and permissions to upload User Content
  • User Content does not infringe any third-party intellectual property rights
  • User Content does not contain unlawful, harmful, or malicious content
  • You comply with all applicable laws in creating and uploading User Content

5.5 User Content Restrictions

You agree not to upload User Content that:

  • Violates any applicable law or regulation
  • Infringes intellectual property rights of others
  • Contains viruses, malware, or harmful code
  • Impersonates any person or entity
  • Contains confidential information belonging to third parties without authorization

5A. SynC Standards Wiki

5A.1 The SynC Standards Wiki

The Services include the SynC Standards Wiki ("SynC Standards"), a collaboratively maintained library of construction reference specifications. This Section 5A applies to all users of the Services, whether or not you contribute to SynC Standards.

SynC Standards are contributed by users of the Services and are licensed to the public under the Creative Commons Attribution-ShareAlike 4.0 International License (CC-BY-SA 4.0). Because SynC Standards are openly licensed, anyone — including users who have never contributed — may use, share, and adapt them, subject to CC-BY-SA 4.0. When SynC Standards content, or an adaptation of it, is redistributed to the public, the redistributor must give attribution to contributors and license the publicly redistributed version under CC-BY-SA 4.0. Use of a SynC Standard within a project is addressed in §5A.7.

5A.2 Contributions Are Governed by the Contributor License Agreement

If you contribute to SynC Standards, your contribution is governed by SynC's separate Contributor License Agreement ("CLA"), which you accept at the time you submit a contribution. The CLA — not these Terms — sets out the terms that apply to contributions, including:

  • the license you grant in your contribution (CC-BY-SA 4.0), the additional permission to use a SynC Standard within a single construction project, and the additional license you grant to SynC to operate and develop the Services;
  • SynC's editorial and moderation rights in respect of contributions;
  • your representations and warranties, including that your contribution is your original work, that you have the right to contribute it, and the terms that apply to AI-assisted content;
  • how contributor attribution is displayed, preserved, and anonymized, including following deletion of your account;
  • the irrevocability of your license grant and its survival after your account is closed; and
  • your indemnification obligations.

To the extent of any conflict between these Terms and the CLA with respect to contributions, the CLA governs. These Terms do not restate or modify the CLA, and nothing in this Section 5A grants SynC any right in a contribution beyond what the CLA grants. You are not required to contribute, and you do not accept the CLA unless and until you submit a contribution.

5A.3 Moderation and Editorial Rights

SynC reserves the right to:

  • Review, edit, modify, or remove any contributed content at its sole discretion
  • Establish and enforce editorial standards, formatting requirements, and quality guidelines
  • Reject contributions that do not meet community standards or quality requirements
  • Suspend or revoke wiki contribution privileges for users who violate these Terms

These editorial and moderation rights operate alongside, and do not limit, SynC's rights under the CLA. As between these Terms and the CLA, the rights exercised over a contribution are those granted by CLA §2E; this Section describes them for the benefit of all users of the Services and adds nothing to them.

5A.4 Attribution

SynC Standards display contributor attribution as required by the CC-BY-SA 4.0 license. The treatment of contributor attribution — including how it is recorded, preserved, and anonymized following deletion of a contributor's account — is governed by the CLA.

5A.5 Disclaimer

SynC Standards are reference specifications developed collaboratively by construction professionals. They are not engineering judgments, professional recommendations, or substitutes for the independent professional judgment of a licensed engineer. Users are solely responsible for verifying the suitability of any standard for their specific project, jurisdiction, and application. Contributors are not liable for downstream use of their contributions.

5A.6 Errata and Revocation of Adopted Revisions

5A.6.1 Adopted Revision Immutability

Once a SynC Standards Wiki revision has been formally adopted, its content is immutable. The platform stores adopted revisions as permanent records that cannot be edited, only superseded by later adopted revisions. Projects may import specific adopted revisions as fixed references, and the platform commits to preserving those references as a load-bearing feature of the Services.

5A.6.2 Errata Annotations

Notwithstanding the immutability principle in §5A.6.1, SynC reserves the right to issue errata — public, non-destructive annotations attached to an adopted revision — at its sole discretion when an error or other issue is identified after adoption. Errata do not modify the content of the adopted revision; the original content remains intact. Errata are displayed as banners or other visual indicators on every page that references the affected adopted revision, including in projects that have already imported the affected revision.

By using the Services, you acknowledge and agree that:

  • Errata may appear on adopted revisions you have imported into your projects after the import has occurred.
  • The platform will display errata banners alongside your imported content, including in projects you have shared and to share-link recipients who have accepted access (see Section 6).
  • Errata are intended as protective annotations to alert readers (including downstream users of your projects) to known issues; they do not unilaterally remove or alter the imported content itself.
  • The decision to act on errata — for example, by upgrading your project to a corrected adopted revision — remains yours.

5A.6.3 Revocation in Extraordinary Circumstances

In extraordinary circumstances, SynC reserves the right to revoke an adopted wiki revision, removing it from public view and from project specifications that reference it. This authority is exercised as narrowly as possible and is reserved for situations including but not limited to:

  • Compliance with valid legal process (court orders, subpoenas, regulatory directives)
  • Response to copyright takedown notices, including but not limited to notices issued under the Digital Millennium Copyright Act ("DMCA")
  • Compliance with data-protection law, including but not limited to erasure requirements under the General Data Protection Regulation ("GDPR") or analogous statutes
  • Removal of content found to constitute a credible threat to public safety
  • Other circumstances in which retention of the adopted revision would expose SynC, its users, or the public to material legal or safety risk

When SynC exercises revocation authority:

  • The action is logged in the public moderation log with the actor identified as the platform and the reason category recorded.
  • Affected project owners are notified through the platform's notification system.
  • Where lawful and practicable, SynC will publish a brief notice explaining the revocation. SynC may, however, omit the notice or limit its content where required by law, court order, or where publication would itself create legal exposure.
  • Where the revocation arises from copyright or content-validity concerns rather than legal compulsion, SynC will, where practicable, retain a non-public copy of the revoked content for the period required to satisfy applicable legal-hold or audit obligations.

5A.6.4 Limits on SynC's Exercise of This Authority

The errata and revocation authority in this Section 5A.6 is SynC's own platform authority, and this Section states its limits. Errata may appear on, and revocation may affect, adopted wiki revisions that have been imported into projects, including projects that have been shared with recipients under Section 6. SynC will exercise this authority only in the circumstances described in §5A.6.2 and §5A.6.3, and will not use it to remove or alter content within a customer's project for ordinary commercial or editorial reasons. Whether a recipient's access to a shared project continues is a matter between the project owner and the recipient under Section 6; nothing in this Section 5A.6 gives SynC any additional right to control, grant, or remove a recipient's access to a shared project.

5A.6.5 No Liability for Erratum or Revocation Action

You acknowledge that SynC's exercise of errata or revocation authority under this section is a protective measure for the user community, the public, or to comply with applicable law. To the maximum extent permitted by law, SynC is not liable to any user, contributor, project owner, or share-link recipient for any consequence of an errata being issued or an adopted revision being revoked, including but not limited to: changes to the appearance of imported content, project workflow disruption, downstream notification obligations between you and your share-link recipients, or any business impact resulting from a published errata or revocation notice.

Errata issued by SynC as the platform are the platform's own speech, and SynC is responsible for their accuracy as such. Errata issued by community moderators through the wiki errata mechanism are community speech hosted and moderated by SynC; SynC's responsibility for community-issued errata is limited to its role as host and moderator.

5A.7 SynC Standards Imported into Projects

5A.7.1 Importing a SynC Standard

The Services allow you to import an adopted revision of a SynC Standard into a project as a starting specification. Importing copies the content of that adopted revision into your project. The adopted revision itself remains available in the public SynC Standards Wiki under CC-BY-SA 4.0 and is not altered, restricted, or removed by your import. Your use of a SynC Standard within a project is supported both by CC-BY-SA 4.0 and by the additional project-use permission that contributors grant under the CLA, and is available to you whether or not you have contributed to SynC Standards.

5A.7.2 The Project Specification

Within a project, you may configure an imported SynC Standard using its built-in datasheet fields, edit its content, and add project-specific requirements. The resulting project specification is your confidential work product. It is private to the project and accessible only to users you authorize and to share-link recipients in accordance with Section 6. Your configuration choices, edits, and project-specific additions are your User Content under §5.1. The SynC Standards content embedded in the project specification remains licensed under CC-BY-SA 4.0; your use of that content within the project is governed by §5A.7.3 and §5A.7.4.

Your project specification is not used as training or research material; see §5.3.1.

5A.7.3 Project Use Is Not Public Redistribution

The ShareAlike and attribution conditions of CC-BY-SA 4.0 are triggered when licensed material, or an adaptation of it, is shared with the public. Importing a SynC Standard into a project, configuring and editing it, and using the resulting project specification within that project — including providing it to the owner, design team, contractors, suppliers, and other identified participants of that project, and submitting it to an authority having jurisdiction for review or permitting — is use of the Standard within a defined project and does not, by itself, constitute making an adaptation available to the public. A project specification used in this manner is not required by CC-BY-SA 4.0 to be published or to be licensed under CC-BY-SA 4.0, and you may treat it as confidential, subject to §5A.7.4.

5A.7.4 Public Distribution Remains Subject to CC-BY-SA 4.0

If you make a SynC Standard, or an adaptation of one (including a project specification derived from a SynC Standard), available to the public — for example by posting it on a publicly accessible website or procurement portal, or otherwise distributing it to the public at large — that distribution is governed by CC-BY-SA 4.0. You must attribute the contributors and license the publicly distributed version under CC-BY-SA 4.0. This obligation applies to the SynC Standards content and adaptations of it; it does not extend to other User Content in your project that is independently authored by you and not derived from a SynC Standard. Nothing in this Section permits you to apply additional restrictions to, or to claim proprietary ownership of, the SynC Standards content itself, as distinct from your own configuration choices, edits, and project-specific additions.

5A.7.5 Attribution of Imported Standards

SynC may display contributor attribution on SynC Standards content imported into projects, including by identifying the source adopted revision. This preserves the attribution and licensing record required by CC-BY-SA 4.0 and is consistent with the Contributor License Agreement.

5B. Copyright Infringement Claims (DMCA Policy)

5B.1 Respect for Intellectual Property

SynC respects the intellectual property rights of others and expects users of the Services to do the same. We respond to notices of alleged copyright infringement that comply with the Digital Millennium Copyright Act ("DMCA"), 17 U.S.C. § 512, and we will remove or disable access to material claimed to be infringing in accordance with this Section.

5B.2 Designated Copyright Agent

Notices of claimed copyright infringement should be sent to SynC's Designated Copyright Agent by email:

Copyright Agent Synergy In Construction, LLC Email: legal@synergyinconstruction.com Subject Line: "DMCA Notice"

The Designated Copyright Agent's current contact details, including any mailing address required to be registered with the United States Copyright Office, are as recorded in the Copyright Office's Directory of Designated Agents.

5B.3 Filing a DMCA Notice

To be effective under 17 U.S.C. § 512(c)(3), your notice must include:

  • A physical or electronic signature of the copyright owner or a person authorized to act on the owner's behalf
  • Identification of the copyrighted work claimed to have been infringed (or, if multiple works are covered by a single notice, a representative list)
  • Identification of the material claimed to be infringing, with information reasonably sufficient to permit us to locate it (for SynC Standards content, the URL or standard identifier and revision)
  • Your contact information (name, address, telephone number, and email address)
  • A statement that you have a good-faith belief that use of the material in the manner complained of is not authorized by the copyright owner, its agent, or the law
  • A statement that the information in the notice is accurate and, under penalty of perjury, that you are authorized to act on behalf of the copyright owner

Under 17 U.S.C. § 512(f), any person who knowingly materially misrepresents that material is infringing, or that material was removed by mistake, may be liable for damages.

5B.4 Counter-Notification

If material you posted was removed or disabled in response to a DMCA notice and you believe the removal was the result of mistake or misidentification, you may submit a counter-notification to the Designated Copyright Agent containing the elements required by 17 U.S.C. § 512(g)(3), including: your physical or electronic signature; identification of the removed material and its prior location; a statement under penalty of perjury that you have a good-faith belief the material was removed as a result of mistake or misidentification; your name, address, and telephone number; and a statement consenting to the jurisdiction of the federal district court for your judicial district (or, if outside the United States, the United States District Court for the Middle District of Florida) and that you will accept service of process from the person who filed the original notice. Upon receipt of a valid counter-notification, we will forward it to the original complainant and may restore the removed material in 10 to 14 business days unless the complainant notifies us that they have filed a court action seeking to restrain the alleged infringement.

5B.5 Repeat Infringer Policy

SynC will, in appropriate circumstances, terminate the accounts of users who are determined to be repeat infringers.

5B.6 Relationship to Wiki Moderation

Where the material subject to a DMCA notice is an adopted SynC Standards revision, removal may be effected through the revocation mechanism described in §5A.6.3, including its logging and notification practices. Removal of contributed material under this Section does not limit SynC's rights, or a contributor's obligations (including indemnification), under the Contributor License Agreement.

6. Project Sharing and Distribution

6.1 Share Links

The Services allow you to create share links to grant other users access to your projects. When creating a share link, you may specify:

  • The level of access granted (Viewer, Editor, or Administrator)
  • Whether recipients may export the shared project through the Services
  • Forwarding limits (whether recipients may re-share with others)
  • Expiration dates for the share link

A recipient's export setting cannot be broadened by forwarding: access forwarded from a share link carries at most the export setting of the link it came from.

6.2 Access Duration and Removal

When a recipient accepts a share link, the recipient is granted access to the shared project at the access level you selected. That access is not permanent. It continues until it ends under this Section:

  • You may remove a recipient's access at any time. Removing a recipient's access ends that recipient's ability to view and interact with the shared project through the Services from the moment of removal. You do not need the recipient's consent, and you do not need to give a reason.
  • Revoking a share link prevents new recipients from accepting it. Revoking a share link does not, by itself, remove access from recipients who have already accepted; removing a recipient's access is a separate control.
  • Deleting a project ends all recipients' access to it.

What removal cannot do. Removing a recipient's access ends their ability to view the project through the Services. It does not, and cannot, retrieve copies of project content that the recipient exported, downloaded, or printed while their access was active. This reflects the practical reality of construction document distribution: requirements that have been transmitted cannot be recalled from a recipient's own records.

If you are a share-link recipient. Your access to a shared project exists at the discretion of the project owner and may be removed at any time, without advance notice to you and without cause. Nothing in these Terms grants a recipient any right to continued access to a shared project, or any right to export it, and SynC has no obligation to any recipient to maintain, restore, or preserve access to a project shared with them. Whether you may export the shared project through the Services is controlled by the party who shared it with you (§6.1). If your work requires a durable record of project content shared with you: where export is available to you, make that record while your access is active; where it is not, request what you need from the party who shared the project with you. These Terms do not grant you any right to copy or retain project content beyond the access and export the sharer has enabled, and any record-keeping arrangement is a matter between you and the sharer.

Limitation: platform-level moderation of wiki content. The access controls in this Section govern the relationship between you and your recipients. Separately, SynC may issue errata on, or in extraordinary circumstances revoke, adopted wiki revisions that your project has imported. See §5A.6 for the scope and limits of that authority.

6.3 Forwarding and Delegation

Recipients with appropriate permissions may forward access to additional users through child share links, subject to:

  • Forwarding depth limits set by the original sharer
  • The access level and restrictions of the parent share link
  • Expiration and revocation of the parent share link (which prevents new child link creation)

6.4 Sharer Responsibilities

When sharing projects, you are solely responsible for:

  • Selecting the appropriate access level and recipients
  • Choosing whether recipients may export the shared project, understanding that an exported copy is outside the control of the Services and cannot be retrieved by removing the recipient's access (§6.2)
  • Managing recipient access over the life of the project, including removing access when appropriate (§6.2)
  • Setting appropriate forwarding limits for your use case
  • Ensuring you have the right to share the project content with the intended recipients
  • Understanding that shared access may be forwarded within the limits you set

SynC is not responsible for any consequences arising from your decision to share project content with specific recipients or from recipients forwarding access within the limits you configured. Where a project specification incorporates content imported from a SynC Standard, your distribution of that specification is also subject to §5A.7.

7. Comments and Collaboration

7.1 Comment Visibility

The Services provide commenting functionality with two visibility levels:

  • Internal: Visible only to members of your company. Use internal comments for proprietary notes, pricing discussions, or competitive information that should not be visible to other project participants.
  • External: Visible to all participants on the project who have comment access.

7.2 Company Isolation

Comments marked as Internal are isolated by company. Other companies participating on the same project cannot see, search, or access your Internal comments. This isolation is enforced at the data layer and cannot be overridden by other project participants.

7.3 User Responsibility for Visibility

You are solely responsible for selecting the appropriate visibility level when creating comments. Once a comment has been marked External and viewed by other participants, the information contained in it has been disclosed. SynC is not responsible for information disclosed through comments you have marked as External.

7.4 Comment Export

Comments may be exported to PDF or Word format. Once exported, the exported document is outside the control of the Services, and SynC cannot manage or restrict its further distribution.

7.5 Comments Are Not Feedback to SynC

A comment you write for the participants in your own project is your User Content, is governed by §5.3.1, and is not sent to SynC as Feedback — including a comment about a SynC Standard you have imported. Where a feature of the Services lets you send a comment, question, or error report to SynC about a Standard in the public library, that feature will say so before you send it, and what you send is Feedback under §8.5.

8. Intellectual Property Rights

8.1 SynC Property

The Services and all content provided by SynC, including but not limited to software, text, graphics, logos, icons, images, audio clips, algorithms, and user interface designs, are owned by SynC or its licensors and are protected by United States and international intellectual property laws, including copyright, trademark, patent, and trade secret laws.

8.2 Trademarks

SynC™, the SynC logo, "Synergy in Construction," and "SynC Standards" are trademarks of Synergy In Construction. You may not use these marks without prior written permission, except to accurately refer to the Services. Third parties who fork or adapt SynC Standards content under the CC-BY-SA license may not use the SynC name, logo, or branding to represent their derivative works as SynC Standards.

8.3 Limited License to Use Services

Subject to your compliance with these Terms, SynC grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Services for your internal business purposes.

8.4 Restrictions

You may not:

  • Copy, modify, create derivative works of, or reverse engineer the Services
  • Remove or alter any copyright, trademark, or proprietary notices
  • Use the Services to develop competing products or services
  • Sell, rent, lease, sublicense, or transfer your rights to the Services
  • Use automated tools (bots, scrapers) to access the Services without authorization

For clarity, nothing in this Section 8.4 limits any right granted to you under the CC-BY-SA 4.0 license with respect to SynC Standards content (Section 5A) or under the Contributor License Agreement's Project Use Permission. Those rights are governed by their own license terms, and the restriction on developing competing products or services applies to the Services' software and platform, not to your exercise of rights in openly licensed SynC Standards content.

8.5 Feedback

If you provide feedback, suggestions, or ideas about the Services, or about the content of the SynC Standards library — including reporting an error in a published Standard, or sending a comment or question to SynC about a Standard through a feature that indicates the content will be sent to SynC — ("Feedback"), you grant SynC a perpetual, irrevocable, worldwide, royalty-free license to use, modify, and incorporate such Feedback into the Services and into the SynC Standards library, without any obligation to you.

If we incorporate Feedback into a published SynC Standard, you additionally license the incorporated material to the public under CC-BY-SA 4.0 as part of that Standard, on the same terms as the rest of that Standard. You agree that attribution to you may be omitted from that Standard, and this Section constitutes a request under Section 3(a)(3) of CC-BY-SA 4.0 that attribution information be removed. If you want your contribution to a Standard credited to you, submit it as a Contribution under the Contributor License Agreement instead of as Feedback.

Feedback is content you direct to SynC. Content you write for the participants in your own project is not Feedback, is not licensed by this Section, and is governed by §5.3.1 — including a comment about an imported Standard that you address to your own project team (§7.5).

This Section is a license to use Feedback in the Services and the SynC Standards library. It is not a license to use Feedback as training or research material, which §5.3.1 forbids.

  • Your use or misuse of the Services
  • Your violation of these Terms
  • Your violation of any applicable laws or regulations
  • Your User Content or its infringement of third-party rights
  • Your use of Materials or AI-generated content in construction projects
  • Your sharing or distribution of project content to third parties

  • Your public distribution of a SynC Standard, or of a project specification derived from one, otherwise than as permitted under §5A.7

16. Termination

16.1 Termination by You

You may terminate your account at any time by contacting support@synergyinconstruction.com or using the account termination feature in the Services.

16.2 Termination by SynC

SynC may suspend or terminate your account and access to the Services immediately, with or without notice, for any reason, including:

  • Violation of these Terms
  • Non-payment of fees
  • Fraudulent or illegal activity
  • Extended inactivity
  • At our discretion for any reason or no reason

16.3 Effect of Termination

Upon termination:

  • Your right to access and use the Services immediately ceases
  • We may delete your User Content after a reasonable retention period
  • You remain liable for all fees incurred prior to termination
  • If SynC terminates your account without cause under Section 16.2 (that is, other than for your violation of these Terms, non-payment, fraudulent or illegal activity, or a security risk), we will refund the pro-rata unused portion of any prepaid subscription fees for the current billing period
  • Access you have granted to other users through share links is not automatically removed by termination of your account; it remains governed by Section 6 and may later end as described in §6.2 (for example, if the project is deleted or a recipient's access is removed by a user with authority over the project)
  • Contributions to SynC Standards licensed under CC-BY-SA 4.0 remain available under that license
  • Your conversations with the AI assistant (§4.2.1) are retained through the period in which your account can still be restored, so that restoring it recovers them, and are deleted when your account is permanently deleted. The Privacy Policy states this rule and its relationship to the retention period for conversations
  • Sections that by their nature should survive (including limitations of liability, indemnification, and dispute resolution) will continue to apply

16.4 Data Retrieval

You may request export of your User Content within 30 days of termination by contacting support@synergyinconstruction.com. After 30 days, we may permanently delete your data.

17. Dispute Resolution; Arbitration Agreement; Governing Law

PLEASE READ THIS SECTION CAREFULLY. IT REQUIRES MOST DISPUTES TO BE RESOLVED THROUGH BINDING INDIVIDUAL ARBITRATION RATHER THAN IN COURT, AND IT WAIVES THE RIGHT TO PARTICIPATE IN CLASS ACTIONS. YOU MAY OPT OUT OF ARBITRATION AS DESCRIBED IN SECTION 17.10.

17.1 Governing Law

These Terms and any disputes arising out of or relating to these Terms or the Services shall be governed by and construed in accordance with the laws of the State of Florida, without regard to its conflict of law principles, except that the Federal Arbitration Act (9 U.S.C. § 1 et seq.) governs the interpretation and enforcement of the arbitration agreement in this Section 17.

17.2 Informal Dispute Resolution First

Before initiating arbitration or any other proceeding, you and SynC agree to first attempt to resolve any dispute informally. The party raising the dispute must send the other a written notice describing the nature of the dispute and the relief sought (to SynC: legal@synergyinconstruction.com; to you: your registered email address). You and SynC agree to negotiate in good faith for at least 60 days after the notice is received. Completion of this informal process is a prerequisite to initiating arbitration or litigation. Applicable statutes of limitations are tolled during this period.

17.3 Agreement to Arbitrate

Except as provided in Section 17.4, you and SynC agree that any dispute, claim, or controversy arising out of or relating to these Terms or the Services (a "Dispute") shall be resolved by final and binding arbitration on an individual basis, rather than in court. This agreement to arbitrate is mutual: it binds you and SynC equally.

17.4 Exceptions to Arbitration

This arbitration agreement does not apply to:

  • Claims that qualify for small claims court, which either party may bring in a small claims court of competent jurisdiction
  • Claims for injunctive or other equitable relief to prevent the actual or threatened infringement, misappropriation, or violation of a party's intellectual property rights, which either party may bring in the courts identified in Section 17.9
  • Any claim that, under applicable law that cannot be waived by agreement, may not be subject to mandatory pre-dispute arbitration

17.5 Arbitration Procedures

The arbitration will be administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules (for individual users) or its Commercial Arbitration Rules (for organizations), as applicable, each as modified by this Section 17. The AAA's rules are available at www.adr.org. A single arbitrator will be appointed in accordance with those rules. The arbitration will be conducted by videoconference or telephone unless the arbitrator determines an in-person hearing is necessary, in which case the hearing will take place in the county where you reside (for individual users) or in Orange County, Florida (for organizations), unless the parties agree otherwise. The arbitrator has exclusive authority to resolve any dispute about the interpretation, applicability, or enforceability of this arbitration agreement, except that only a court may decide the enforceability of the class action waiver in Section 17.7. Judgment on the arbitration award may be entered in any court of competent jurisdiction.

17.6 Arbitration Fees

Payment of AAA filing, administrative, and arbitrator fees will be governed by the applicable AAA rules. For individual users, if you are unable to obtain a fee waiver and your claim seeks less than $10,000, SynC will pay the portion of the AAA filing fee that exceeds the cost of filing the same claim in the courts identified in Section 17.9, together with the administrative and arbitrator fees allocated to consumers under the AAA Consumer Arbitration Rules. Each party bears its own attorneys' fees and costs except where applicable law provides otherwise or the arbitrator determines that a claim or defense was frivolous or brought for an improper purpose.

17.7 Class Action Waiver

TO THE EXTENT PERMITTED BY LAW, YOU AND SYNC AGREE THAT EACH MAY BRING DISPUTES AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING. The arbitrator may not consolidate more than one person's claims and may not preside over any form of class or representative proceeding. If a court of competent jurisdiction holds this class action waiver unenforceable as to a particular Dispute, then the agreement to arbitrate in Section 17.3 shall not apply to that Dispute, which shall instead proceed in the courts identified in Section 17.9; in no event shall any class, collective, or representative Dispute proceed in arbitration.

17.8 Coordinated Filings

If 25 or more demands for arbitration raising similar Disputes are filed against SynC with the assistance or coordination of the same counsel or coordinated counsel, the parties agree the demands shall be resolved in staged proceedings: up to ten demands selected by claimants' counsel and up to ten selected by SynC shall proceed first as bellwether arbitrations, while the remaining demands are held in abeyance (with filing fees deferred and limitations periods tolled). Following the bellwether arbitrations, the parties shall engage in a good-faith global mediation before any remaining demand proceeds. If this Section is held unenforceable as to any demand, that demand shall proceed in the courts identified in Section 17.9.

17.9 Jurisdiction and Venue for Court Proceedings

For any Dispute not subject to arbitration under this Section 17, you agree that the action shall be brought exclusively in the state courts located in Orange County, Florida, or in the United States District Court for the Middle District of Florida (Orlando Division), and you irrevocably consent to the personal jurisdiction and venue of such courts.

17.10 Your Right to Opt Out of Arbitration

You may opt out of the arbitration agreement in Sections 17.3 through 17.8 by emailing legal@synergyinconstruction.com with the subject line "Arbitration Opt-Out" — including your name, the email address associated with your account, and a clear statement that you wish to opt out of arbitration — within 30 days of the date you first accept these Terms. Opting out of arbitration does not affect any other provision of these Terms, including Section 17.9 (Jurisdiction and Venue). An opt-out applies only to the individual or organization that submits it.

18. General Provisions

18.1 Entire Agreement

These Terms, together with our Privacy Policy and any additional terms applicable to specific Services, constitute the entire agreement between you and SynC regarding the Services and supersede all prior agreements and understandings.

18.2 Modifications to Terms

SynC reserves the right to modify these Terms at any time. We will provide notice of material changes by:

  • Posting updated Terms with a new Effective Date
  • Sending email notification to your registered email address
  • Displaying a prominent notice in the Services

Continued use of the Services after changes become effective constitutes acceptance. If you do not agree to modified Terms, you must discontinue use of the Services.

18.3 Severability

If any provision of these Terms is found to be invalid, illegal, or unenforceable, the remaining provisions shall continue in full force and effect.

18.4 Waiver

No waiver of any provision of these Terms shall be deemed a further or continuing waiver of such provision or any other provision. Our failure to enforce any right or provision of these Terms shall not constitute a waiver of such right or provision.

18.5 Assignment

You may not assign or transfer these Terms or your account without our prior written consent. SynC may assign these Terms or its rights hereunder without restriction.

18.6 Force Majeure

SynC shall not be liable for any delay or failure to perform resulting from causes beyond our reasonable control, including acts of God, war, terrorism, labor disputes, governmental actions, internet disruptions, or failure of third-party services.

18.7 Export Compliance

You agree to comply with all applicable export and import laws and regulations in your use of the Services.

18.8 Government Use

If you are a U.S. government entity, the Services are "commercial computer software" and "commercial computer software documentation" as defined in FAR 12.212 and DFARS 227.7202, and your rights are limited to those expressly granted in these Terms.

18.9 Relationship of Parties

Nothing in these Terms creates a partnership, joint venture, agency, or employment relationship between you and SynC.

20. Acknowledgment

By clicking "I Accept," creating an account, or using the Services, you acknowledge that:

  • You have read and understood these Terms
  • You agree to be bound by these Terms
  • You have the authority to enter into these Terms
  • You understand the limitations and disclaimers regarding AI-generated content and construction Materials
  • SynC does not use your content to train generative or foundation AI models, and de-identifying content does not make it non-confidential (§5.3.1) — except for content you deliberately submit to the SynC Standards library, which the Contributor License Agreement governs, and feedback you direct to SynC, which §8.5 governs. SynC may build models inside the Services that classify, score, or flag content without generating text, on the conditions stated in §5.3.1. We do measure how the Services are used (§5.3.2), and we transmit the content you are working with to inference and embedding providers that are barred from retaining or training on it (§5.3.3)
  • Your conversations with the AI assistant are stored, are private to you, are retained for the period stated in the Privacy Policy and then deleted, and may be deleted by you at any time (§4.2.1)
  • You understand that a project owner may remove a share-link recipient's access to a shared project at any time, and that removal does not retrieve copies of project content a recipient exported while their access was active (§6.2)
  • You understand that SynC Standards are licensed to the public under CC-BY-SA 4.0, and that if you contribute to SynC Standards your contribution is governed by the separate Contributor License Agreement (§5A.2)
  • You understand that SynC may issue errata on, or in extraordinary circumstances revoke, adopted SynC Standards revisions that you have imported into your projects, as described in §5A.6
  • You understand that a SynC Standard imported into your project and configured for that project is your confidential work product, while the embedded SynC Standards content remains licensed under CC-BY-SA 4.0 and its public distribution remains subject to that license (§5A.7)
  • You understand that comment visibility is your responsibility and that External comments are visible to all project participants
  • You understand that Section 17 requires most disputes to be resolved through binding individual arbitration and waives class actions, subject to the exceptions and the 30-day opt-out right described in that Section

21. Summary of Changes from Version 1.1

This summary is provided for convenience and is not a substitute for the operative text above. Version 1.4 carries Terms of Service v1.1 forward in full, integrates two amendments that were previously drafted and reviewed as separate parallel tracks (the v1.2 errata/revocation-authority draft and the v1.3 standards-project-use draft), and adds the protective provisions adopted in the June 2026 legal-document review. No prior obligation, definition, or user right from v1.1 is removed, except that the dispute-resolution provisions in §17 are restructured as described below.

  • New §5A.6 (Errata and Revocation of Adopted Revisions). Establishes adopted-revision immutability, SynC's reserved authority to issue public non-destructive errata (including on revisions already imported into projects and held under Vested Access), a narrow revocation authority for extraordinary circumstances (legal process, DMCA, GDPR erasure, public-safety, or material legal/safety risk), the relationship of this authority to Vested Access, and a no-liability provision distinguishing platform-issued errata (SynC's own speech) from community-moderator errata (hosted community speech). (From the v1.2 draft.)
  • New §5A.7 (SynC Standards Imported into Projects). Clarifies that importing a SynC Standard into a project and configuring/editing it produces a confidential project specification; that project-internal use and distribution to identified project participants and to an authority having jurisdiction is not public redistribution under CC-BY-SA 4.0; and that public distribution of a Standard or an adaptation of one remains subject to CC-BY-SA 4.0 attribution and ShareAlike. (From the v1.3 draft.)
  • Restructured §5A (SynC Standards Wiki). Section 5A no longer restates the contribution license grant or contributor representations and warranties. Those terms are governed by SynC's separate Contributor License Agreement (CLA), to which §5A.2 now defers (the CLA controls in the event of any conflict as to contributions). This removes the overlap and potential conflict between the prior ToS §5A.1/§5A.2 and the CLA — for example, the prior §5A.4 stated contributors are "credited by name," which is inconsistent with the CLA's automatic anonymization of attribution on account deletion. Section 5A retains the wiki-and-license information relevant to all users — including readers and project users who never contribute: that SynC Standards are licensed to the public under CC-BY-SA 4.0 (§5A.1, incorporating the v1.3 clarification that attribution and ShareAlike attach to public redistribution, not to private or project use), the moderation and editorial rights (§5A.3), how attribution is displayed (§5A.4, with details governed by the CLA), the reference-material disclaimer (§5A.5), the errata and revocation authority (§5A.6), and project use (§5A.7).
  • §6.2 (Vested Access). Adds a limitation clause putting project owners on notice that Vested Access does not prevent SynC from issuing errata or revoking imported adopted wiki revisions, cross-referencing §5A.6. (From the v1.2 draft.)
  • Conforming cross-references. §5.1, §6.4, §14.1, §15, and §20 were updated to cross-reference the new §5A.6, §5A.7, and the CLA where relevant. These are conforming edits, not new obligations.
  • Entity-name correction. The provider is now identified consistently as "Synergy In Construction, LLC, a Wyoming limited liability company," correcting the prior description "a Wyoming corporation" in the preamble and conforming the notice block in §19.1. This aligns the Terms with the legal entity named in the Contributor License Agreement and the Privacy Policy. It corrects the entity's legal description only and does not change any party's rights or obligations.
  • New §5B (Copyright Infringement Claims / DMCA Policy). Adds a complete DMCA notice-and-takedown framework: a Designated Copyright Agent and contact details (§5B.2), the required elements of an infringement notice (§5B.3) and counter-notification (§5B.4), a repeat-infringer termination policy (§5B.5), and the relationship between DMCA removals and the wiki revocation mechanism in §5A.6.3 (§5B.6). This implements the apparatus required for the DMCA §512 safe harbor for user-contributed content.
  • New §17 (Dispute Resolution; Arbitration Agreement). Replaces court litigation plus a standalone class-action waiver with a mutual agreement to resolve Disputes by binding individual arbitration (AAA rules), with carve-outs for small-claims court and intellectual-property injunctive relief (§17.4), consumer-protective fee allocation (§17.6), the class-action waiver relocated inside the arbitration agreement with a blow-up clause sending class Disputes to court rather than class arbitration if the waiver is held unenforceable (§17.7), a staged-bellwether protocol for coordinated mass filings (§17.8), and a 30-day right to opt out of arbitration entirely (§17.10). The 60-day informal-resolution prerequisite from v1.1 §17.3 is retained as §17.2.
  • New §4.5 (Beta and Preview Features). Disclaims availability and support commitments for features offered on an alpha, beta, preview, pilot, or early-access basis, reflecting the platform's active-development status.
  • §5.3.3 (AI Training). Retitled "Current Practice and Opt-Out Rights"; states that as of the Effective Date SynC does not train AI models on User Content and that the Section preserves the right to do so, and commits to obtaining opt-in consent where applicable law requires it before using User Content for AI training. This aligns the Terms with the Privacy Policy's GDPR legal-basis disclosure.
  • §8.4 (Restrictions). Adds a clarification that the restrictions — including the restriction on developing competing products — do not limit rights granted under the CC-BY-SA 4.0 license to SynC Standards content or under the CLA's Project Use Permission, resolving the apparent tension with §8.2's acknowledgment that third parties may fork openly licensed content.
  • §10.1 / §16.3 (Fees and Termination). Adds a pro-rata refund of prepaid subscription fees for the current billing period if SynC terminates an account without cause.
  • §13.1. Corrects the typographical error "SYNCING STANDARDS WIKI CONTENT" to "SYNC STANDARDS WIKI CONTENT."
  • §20 (Acknowledgment). Adds an acknowledgment of the arbitration agreement, class-action waiver, and arbitration opt-out right.

22. Summary of Changes from Version 1.4

This summary is provided for convenience and is not a substitute for the operative text above. Version 1.5 carries Terms of Service v1.4 forward in full. Every section other than those listed below is unchanged. Section 21 above is retained verbatim as the historical record of what v1.4 changed; the entity-name correction it describes reflected the entity's then-current Wyoming domestication, which this version supersedes.

  • The entity redomesticated from Wyoming to Florida. Synergy In Construction, LLC completed a statutory conversion from a Wyoming limited liability company to a Florida limited liability company, effective upon the entity becoming active in Florida on August 2, 2026. A statutory conversion is a change of the entity's state of organization, not the creation of a new entity: the same legal entity continues, with the same Employer Identification Number, and it remains bound by and entitled to enforce every agreement it had already entered into. No contract, account, subscription, license grant, or obligation is transferred, assigned, novated, or terminated by the conversion. The provider is accordingly now identified throughout as "Synergy In Construction, LLC, a Florida limited liability company" (preamble, §19.1). This change of description does not, in itself, affect any party's rights or obligations.

  • Governing law moved from Wyoming to Florida (§17.1). This is a material change and it does affect the parties' rights: the substantive law applied to these Terms and to disputes arising under them is now Florida law rather than Wyoming law. The prior text read:

    These Terms and any disputes arising out of or relating to these Terms or the Services shall be governed by and construed in accordance with the laws of the State of Wyoming, without regard to its conflict of law principles, except that the Federal Arbitration Act (9 U.S.C. § 1 et seq.) governs the interpretation and enforcement of the arbitration agreement in this Section 17.

    It now reads:

    These Terms and any disputes arising out of or relating to these Terms or the Services shall be governed by and construed in accordance with the laws of the State of Florida, without regard to its conflict of law principles, except that the Federal Arbitration Act (9 U.S.C. § 1 et seq.) governs the interpretation and enforcement of the arbitration agreement in this Section 17.

    The Federal Arbitration Act carve-out is unchanged: the FAA continues to govern the interpretation and enforcement of the arbitration agreement in §17, so the change of governing law does not alter the law applied to the arbitration agreement itself. Only the law applied to the balance of these Terms, and to Disputes that are not subject to arbitration, changes.

  • Court venue moved from Wyoming to Florida (§17.9). This is a material change and it does affect the parties' rights: the forum in which a non-arbitrable Dispute must be brought has moved. The prior text read:

    For any Dispute not subject to arbitration under this Section 17, you agree that the action shall be brought exclusively in the state or federal courts located in Sheridan County, Wyoming, and you irrevocably consent to the personal jurisdiction and venue of such courts.

    It now reads:

    For any Dispute not subject to arbitration under this Section 17, you agree that the action shall be brought exclusively in the state courts located in Orange County, Florida, or in the United States District Court for the Middle District of Florida (Orlando Division), and you irrevocably consent to the personal jurisdiction and venue of such courts.

    The federal forum is now named expressly rather than by reference to "federal courts located in" the named county, because the federal court sitting in Orange County, Florida is the Orlando Division of the Middle District of Florida. The carve-outs in §17.4 are unaffected: small-claims claims may still be brought in any small claims court of competent jurisdiction, and claims for intellectual-property injunctive relief are routed to the courts identified in §17.9 as they were before. §17.6 (which measures SynC's filing-fee contribution against "the cost of filing the same claim in the courts identified in Section 17.9") and §17.7 and §17.8 (which send class Disputes and unenforceable coordinated-filing demands to "the courts identified in Section 17.9") pick up the new forum automatically and were not otherwise changed.

  • Arbitration hearing location moved from Wyoming to Florida (§17.5). Where an in-person arbitration hearing is required, the location for organizational users is now Orange County, Florida rather than Sheridan County, Wyoming. This affects organizational users' rights as to hearing location. The rule for individual users is unchanged and unaffected: an in-person hearing for an individual user still takes place in the county where that user resides.

  • DMCA counter-notification default forum (§5B.4). For a counter-notifying party located outside the United States, the consented federal forum is now the United States District Court for the Middle District of Florida, replacing the District of Wyoming. This conforms the §512(g)(3)(D) consent to the district in which SynC may now be found. It affects the rights only of a counter-notifying party outside the United States, and only as to forum.

  • The street address was removed; contact is by email (preamble, §5B.2, §19.1). SynC no longer publishes a street address in these Terms. The party is identified as "Synergy In Construction, LLC, a Florida limited liability company," and notices to SynC are given by email to legal@synergyinconstruction.com (§19.1), DMCA notices and counter-notifications by email to the Designated Copyright Agent at the same address (§5B.2), and support requests to support@synergyinconstruction.com (§19.3). These are the same mailboxes the Terms already designated for these purposes, so no method of contact available to you under v1.4 has been withdrawn other than postal mail, and the informal-dispute-resolution notice in §17.2 and the arbitration opt-out in §17.10 were already email-based and are unchanged. §5B.2 now also states that the Designated Copyright Agent's registered contact details, including any mailing address required to be registered with the United States Copyright Office, are as recorded in that office's Directory of Designated Agents. Notice to you (§19.2) is unchanged and still may be given by mail to your address on file.

  • No other change. No definition, license grant, disclaimer, limitation of liability, indemnity, fee term, termination right, wiki or standards provision, arbitration procedure, class-action waiver, or opt-out right is added, removed, or modified by v1.5.

Notice of these changes. Section 18.2 requires SynC to give notice of material changes by posting these Terms with a new Effective Date, sending email notification to your registered email address, and displaying a prominent notice in the Services. The governing-law, venue, and arbitration-location changes above are material, and notice is given by all three of those means. Section 18.2 does not prescribe an advance-notice period, and none is taken here; these Terms take effect on their Effective Date. The changes operate prospectively.

23. Summary of Changes from Version 1.5

This summary is provided for convenience and is not a substitute for the operative text above. Version 1.6 carries Terms of Service v1.5 forward in full. Every section other than those listed below is unchanged. Sections 21 and 22 above are retained verbatim as the historical record of what v1.4 and v1.5 changed; their references to "Vested Access" describe provisions as they existed in those versions.

  • "Vested Access" is removed; project access granted through share links is now revocable by the project owner (§6.2). This is a material change. Former §6.2 provided that a recipient who accepted a share link obtained permanent access to the shared project revision, that revoking a share link did not affect access already granted, and that the sharer could not unilaterally revoke a recipient's access. The Services now provide the opposite: a project owner may remove a recipient's access at any time, and deleting a project ends all recipients' access. New §6.2 (retitled "Access Duration and Removal") states this, states what removal cannot do — it does not retrieve copies a recipient exported, downloaded, or printed while their access was active — and puts recipients on notice that access to a shared project exists at the project owner's discretion and that these Terms grant a recipient no right to continued access. No recipient accepted a share under the v1.5 language, so no access granted under the former provision exists to be affected by this change.
  • §6.1 and §6.4 disclose the per-link export control. A sharer now chooses, per share link, whether recipients may export the shared project through the Services, and access forwarded from a share link carries at most the export setting of the link it came from. §6.2's recipient notice conditions its record-keeping guidance on this setting — a recipient whose export is not enabled is directed to the sharer, and the Terms grant no right to copy or retain content beyond the access and export the sharer enabled. §6.4 makes the export choice, and its consequence — an exported copy is outside the control of the Services and is not retrieved by removing access — an express sharer responsibility.
  • §5A.6.4 restated as a freestanding limit on SynC's authority. Former §5A.6.4 ("Effect on Vested Access") framed SynC's errata and revocation authority as an exception to the Vested Access principle. With that principle removed, §5A.6.4 (retitled "Limits on SynC's Exercise of This Authority") restates the same commitment as a direct limit: SynC exercises the §5A.6 authority only in the circumstances described in §5A.6.2 and §5A.6.3 and will not use it to remove or alter content within a customer's project for ordinary commercial or editorial reasons. The scope of the errata and revocation authority itself (§5A.6.2, §5A.6.3) is unchanged.
  • Conforming edits. §5A.6.2 (errata-banner acknowledgment), §6.4 (sharer responsibility for managing recipient access), §16.3 (effect of account termination on shared access), and §20 (acknowledgment) were conformed to the removal of Vested Access. These carry no obligations beyond those stated in §6.2 and §5A.6.4.
  • No other change. No definition, license grant, disclaimer, limitation of liability, indemnity, fee term, wiki or standards provision, arbitration procedure, or opt-out right is otherwise added, removed, or modified by v1.6. The retention of records of distribution events is addressed in the Privacy Policy (v1.7), not these Terms.

Notice of these changes. The replacement of §6.2 is a material change and notice is given by the three means Section 18.2 provides. As of the Effective Date, no share had been accepted under the former §6.2, so the change operates prospectively and affects no access previously granted.

24. Summary of Changes from Version 1.6

This summary is provided for convenience and is not a substitute for the operative text above. Version 1.7 carries Terms of Service v1.6 forward in full. Every section other than those listed below is unchanged. Sections 21 through 23 are retained verbatim as the historical record of what v1.4, v1.5, and v1.6 changed.

Every change in this version but one runs in the same direction: SynC gives up rights it had reserved over your content, and states more precisely what it does instead. No fee, liability, indemnity, dispute-resolution, or sharing provision is touched.

The one exception is §8.5 (Feedback), which is broader than before. It now reaches feedback you direct to SynC about the content of the SynC Standards library, which it did not previously cover, and it takes a perpetual, irrevocable licence over that material — including, where SynC incorporates it into a published Standard, a licence to the public under CC-BY-SA 4.0. That is a genuine extension and it is described in full below. It applies only to content you choose to send to SynC; §7.5 and §5.3.1 keep everything you write for your own project outside it.

  • §5.3 renamed and reframed as a limit, not a grant. The heading "Data Usage for Service Improvement and AI Training" and the notice "You grant SynC the right to use User Content in the following ways" are replaced by "Limits on Our Use of Your Content" and a statement that the Section is a limit on SynC's rights. The Section's carve-in for legal and business disclosures described in the Privacy Policy (for example, response to legal process under §5A.6.3, and business transfer) is stated expressly so the limit is accurate rather than absolute.

  • §5.3.1 replaced: SynC will not use your content as training or research material. This is the substantive change. Former §5.3.1 permitted SynC to anonymize User Content — by removing names, company names, and project names — and to use the result to train AI models, develop features, conduct research, and create industry benchmarks, and stated that once anonymized the content "is not considered confidential." That permission is withdrawn in full and does not survive in any form. New §5.3.1 states that SynC does not use User Content, or any adaptation or excerpt of it, to train, fine-tune, or improve any generative AI model, or any general-purpose or foundation model, whether SynC's own or a third party's, and whether or not it has been anonymized, de-identified, or aggregated; and does not license, sell, publish, or otherwise disclose User Content to any third party for those purposes. It further states that removing identifying details from a specification does not change its confidential status.

    Two boundaries are drawn expressly rather than left to interpretation. Operational models — models that classify, score, match, rank, or flag content inside the Services, such as identifying what kind of value a datasheet field holds or detecting an entry outside its normal range — sit outside the prohibition, but only if all three stated conditions hold: the model produces structured outputs and does not generate text; it is used only to operate the Services and is never distributed, licensed, or sold; and neither it nor its outputs reproduce your content to anyone not already authorized to see it. Where such a model is built from more than one customer's content, it may be used only to operate the Services and never to disclose one customer's content to another. The "does not generate text" condition is the load-bearing one: a model that emits only labels and scores has no channel through which a specification could surface, which is a property that can be verified from the model's design rather than asserted about its behaviour.

    Separately, SynC may use User Content in a way §5.3.1 otherwise prohibits only under a separate written agreement you execute that identifies the content and the use. Accepting these Terms is not such an agreement, and SynC will not require one as a condition of providing the Services to you — so the exception cannot become a default by attrition.

    The former clause was also internally inconsistent with §5A.7.2, which promises that a project specification is your confidential work product. Both could not be true of the same document. That conflict is resolved in favour of confidentiality.

    This change is retroactive. New §5.3.1 applies to all User Content whenever submitted, including content submitted before this version took effect. Nothing was ever done under the former clause — v1.6 §5.3.3 already stated that SynC did not train AI models on User Content — so no use made under it needs to be unwound.

    §5.3.1 states four things it does not restrict: content you offer for inclusion in the SynC Standards library, which the Contributor License Agreement governs (a); Feedback you direct to SynC, which §8.5 governs (b); SynC Standards content as published in the public library, which is licensed under CC-BY-SA 4.0 (c); and the statistics described in §5.3.2 (d). Paragraphs (a) and (b) describe content you deliberately send outward, not content that sits in your project: §5.3.1 states expressly that content you write inside your own project for your own project's participants is not a Contribution and does not become one because it concerns a Standard you imported.

  • §5.3.2 replaced: the line is drawn at expression. Former §5.3.2 permitted collection and analysis of "usage patterns, feature utilization, and interaction data." New §5.3.2 keeps that and states what it covers and what it does not: counts, frequencies, distributions, timings, error rates, and feature-utilization patterns are measurements about content, and may not include or be used to reconstruct the text of your specifications. Where a statistic could identify an individual customer, it is reported only in aggregate. This narrows what §5.3.2 permits by drawing an express boundary that the former text left open.

  • §5.3.3 replaced: the AI-training opt-out is removed because the use it opposed is gone. Former §5.3.3 stated that SynC did not currently train on User Content, reserved the right to begin doing so, and offered an opt-out and a commitment to obtain opt-in consent where law required it. The reserved right is withdrawn by new §5.3.1, so the opt-out has nothing to operate on and is removed. No user is disadvantaged: the practice being opted out of never occurred, and the new position is stronger than any opt-out — the use is forbidden for everyone rather than declinable by request. New §5.3.3 addresses what actually happens instead: delivering AI features and search requires transmitting the content you are working with to inference and embedding providers, and SynC does not permit those providers to retain your content for their own purposes or to train on it, enforcing this by technical configuration rather than by a direct contract with each host. It names no vendor and no jurisdiction, because both change; those are disclosed in the Privacy Policy and on the subprocessor list it references. SynC may change providers, hosts, or mechanisms, and will give notice under §18.2 before a change that materially reduces the protections described in the Section takes effect. The Section deliberately does not freeze the level of protection at the level in force when you accept — it commits to telling you before it moves downward, so that you can decide what to do about it.

  • §5.2 conformed. "Create derivative works as necessary to provide and improve the Services" becomes "to provide the Services and to operate them as described in §5.3." A general "improve the Services" grant sitting above a Section that forbids model improvement is a seam; the licence is now expressly bounded by §5.3.

  • §8.5 (Feedback) extended to the SynC Standards library. Former §8.5 licensed feedback "about the Services." It now expressly covers feedback about the content of the SynC Standards library — including reporting an error in a published Standard, and sending a comment or question to SynC about a Standard through a feature that indicates the content will be sent to SynC — and the licence extends to incorporating Feedback into the library as well as the Services. Two limits are stated in the same Section. First, Feedback is content you direct to SynC; content you write for the participants in your own project is not Feedback and is governed by §5.3.1. Second, the licence is to use Feedback in the Services and the library — it is not a licence to train models on it, which §5.3.1 forbids regardless.

    A third limit closes a licensing gap in the same Section. The SynC Standards library is published to the public under CC-BY-SA 4.0. A licence permitting SynC to incorporate Feedback into the library would not, by itself, permit SynC to publish the incorporated material under CC-BY-SA — so the first time a report containing proposed text was folded into a Standard, SynC would be publishing material it had no right to licence onward, and §5A.1 would be false as to that material. §8.5 therefore also licenses the incorporated material to the public under CC-BY-SA 4.0 as part of the Standard, and treats the Section as a request under CC-BY-SA 4.0 §3(a)(3) that attribution be omitted. Anyone who wants their contribution credited is directed to submit it as a Contribution under the Contributor License Agreement instead, which preserves attribution under CLA §2B.

    This closes a gap the amendment would otherwise have opened. Contributor License Agreement §1 excludes discussion, commentary, and feedback features from the definition of a Contribution, so a report of an error in a Standard is not a Contribution; and new §5.3.1 forbids SynC from using User Content to improve anything. Without this change an error report would have been covered by neither instrument, and SynC could not have acted on it.

  • New §7.5 (Comments Are Not Feedback to SynC). States in the comments Section what §5.3.1 and §8.5 establish: a comment you write for your project's participants stays with your project, and a feature that sends something to SynC about a public Standard will say so before you send it. This creates an obligation on SynC, not on you — the labelling requirement is what makes the distinction between §5.3.1 content and §8.5 Feedback observable rather than a matter of SynC's characterization after the fact.

  • §5A.2 and §5A.3 conformed to the Contributor License Agreement. §5A.2's list of what the CLA governs now also names the additional licence contributors grant SynC (CLA §2D) and SynC's editorial and moderation rights (CLA §2E). §5A.3 states that the rights it describes are those granted by CLA §2E and that this Section adds nothing to them. This is a correction of a structural defect, not a new right. §5A.2 provides that nothing in Section 5A grants SynC any right in a contribution beyond what the CLA grants, and that the CLA governs any conflict — so §5A.3's moderation rights were, as drafted, subordinated to a CLA that did not expressly grant them. CLA v2.4 §2E now does.

  • §5A.7.2 (The Project Specification). One sentence appended: your project specification is not used as training or research material, cross-referencing §5.3.1. The Section's substance is unchanged; the sentence puts the promise where a reader looking at project confidentiality will find it.

  • §4.2 (AI-Powered Features). One sentence appended cross-referencing §5.3.3 for how content reaches third-party AI services and what they may do with it. No change to the AI disclaimers.

  • §20 (Acknowledgment) corrected. The acknowledgment "You acknowledge that SynC may use anonymized User Content for AI training and service improvement" stated the opposite of v1.6 §5.3.3's operative term and is deleted. It is replaced with a plain-language statement of §5.3.1, §5.3.2, and §5.3.3 and their exceptions. A reader who reads only the acknowledgment now gets the same answer as a reader who reads the operative text.

  • Drafting annotations removed. The inline reviewer's notes carried in the v1.6 reference file were editorial annotations addressed to counsel, not terms, and were already excluded from the published v1.6 by the publishing migration's content guard. They are not carried into this version's text. No operative sentence they annotated is changed by their removal. Open items are recorded in Appendix A, which is not part of these Terms.

  • No other change. No definition, disclaimer, limitation of liability, indemnity, fee term, termination right, sharing or distribution provision, wiki errata or revocation provision, arbitration procedure, class-action waiver, or opt-out right is added, removed, or modified by v1.7, other than the removal of the AI-training opt-out described above, which is removed because the practice it applied to is now prohibited outright.

Notice of these changes. The withdrawal of a reserved right to use User Content for AI training, the removal of the corresponding opt-out, and the extension of the Feedback licence are material changes, and notice is given by the three means Section 18.2 provides. The changes to §5.3 operate retroactively as stated in §5.3.1, which is to your benefit; every other change operates prospectively.

25. Summary of Changes from Version 1.7

This summary is provided for convenience and is not a substitute for the operative text above. Version 1.8 carries Terms of Service v1.7 forward in full. Every section other than those listed below is unchanged. Sections 21 through 24 are retained verbatim as the historical record of what v1.4 through v1.7 changed.

This version makes one change, and it is a disclosure rather than a reallocation of rights. The Services now store your conversations with the AI assistant instead of holding them only in your browser. No licence, ownership, disclaimer, limitation of liability, indemnity, fee, sharing, wiki, or dispute-resolution provision is added, removed, or modified.

  • New §4.2.1 (Your Conversations with the AI Assistant). States four things: that conversations are stored so that they remain available to you after you close them; that a conversation is your own record and private to you — no other user can view one through the Services, conversation content enters no published document, revision record, or export of project content, and a conversation is retained for you even where you later cease to have access to material discussed in it; that conversations are retained for a stated period and then deleted automatically; and that you may delete any conversation at any time and copy one out as readable text. It also states that the messages you send to the assistant are your User Content under §5.1, so §5.3 — including the prohibition on using your content as training or research material in §5.3.1 — applies to them.

    The retention period is not stated here. §4.2.1 cross-references the Privacy Policy, which defines the period, states how it is measured, and states its relationship to account deletion. This follows the practice these documents already use for the AI-provider constraints in §5.3.3 and for the distribution-record retention rule: one definition, in one document. A period restated in two instruments is a period that will eventually be stated two different ways.

  • §16.3 (Effect of Termination) extended by one bullet. Records that conversations are retained through the period in which a terminated account can still be restored — so that restoring the account recovers them — and are deleted when the account is permanently deleted. This is where a reader closing an account will look for it.

  • §20 (Acknowledgment) extended by one bullet, stating §4.2.1 in plain language so that a reader of the acknowledgment gets the same answer as a reader of the operative text.

  • No other change. Nothing in §5 (including §5.1 ownership and the §5.3 limits), §5A, §5B, §6, §7, §8, §9 through §15, §17, §18, or §19 is added, removed, or modified by v1.8.

Notice of these changes. The Services beginning to retain a category of your content that was not previously retained is a material change, and notice is given by the three means Section 18.2 provides, in step with the corresponding Privacy Policy version. The change operates prospectively.
