End-User License Agreement (EULA)

Effective Date: October 12, 2025

Last Updated: September 6, 2026

1. Overview

This End-User License Agreement (“Agreement”) is between Synoro Inc. (“Synoro,” “we,” “our,” or “us”) and the end user (“you,” “your,” or “user”). By accessing or using Synoro's services, platform, or applications (collectively, the “Services”), including connecting a third-party AI assistant through Model Context Protocol (MCP) or a similar connector, you agree to be bound by this Agreement.

2. License Grant

Synoro grants you a non-exclusive, non-transferable, revocable license to use the Services solely for your internal business purposes in accordance with this Agreement and applicable law.

3. Ownership

All intellectual property rights in the Services—including software, AI models, documentation, design, and data—are and remain the exclusive property of Synoro and its licensors. This Agreement does not transfer ownership of any Synoro intellectual property.

4. User Responsibilities

You agree to:

  • Use the Services only for lawful purposes.
  • Maintain the confidentiality of your login credentials.
  • Not reverse engineer, modify, copy, or resell the Services.
  • Ensure that your data shared with Synoro is accurate and authorized.
  • Authorize assistant connections only for firms and companies you are permitted to access, and revoke grants you no longer intend to keep.

5. Assistant connections (MCP and similar)

The Services may let you connect third-party AI assistants and similar clients—such as ChatGPT, Claude, or other MCP-compatible applications—to your Synoro firm. Authorizing a connection is a grant from you, as a signed-in Synoro user, to that assistant. It is not a workspace-wide API key and it does not replace Synoro's approvals, company visibility, or firm policies.

You understand and agree that:

  • Access is limited to your current firm membership, the companies you can already see, and the permission level of the grant. Assistant OAuth connections use full access, meaning the assistant may use Synoro tools this user is already allowed to use. Approvals and company policies still apply.
  • If you grant access to all companies you can see, the assistant may reach every such company until the grant is revoked. If you also include companies created later, the grant can extend to companies added after you authorize, including companies assigned to you later, until revoked.
  • If you pick specific companies, or if your role requires you to pick companies (for example, bookkeepers), the grant covers only those companies. New companies are not included until you add them and re-authorize or update the grant.
  • An authorized assistant may call published Synoro tools on your behalf: listing companies, reading operational and accounting snapshots, reading workflow and document metadata you can already access, proposing categorizations, drafting client questions, recording external-work lifecycle events, and starting a single-company QuickBooks refresh when that scope is granted.
  • Tool results may include business text already stored in Synoro (vendor names, memos, comments, document names, and similar). That content is shared with the assistant you authorized. Synoro does not treat that text as a request to change firm, company, scope, or tools.
  • Published writes stay bounded. Categorization drafts and client-question drafts create pending Synoro suggestions only. They do not approve themselves, post to QuickBooks, mark work complete, or send email, Telegram, Slack, or other external messages. Approving or rejecting accounting suggestions happens in Synoro.
  • Confirming a tool argument in the assistant is not authorization. Synoro re-checks membership, company visibility, scopes, and firm policy on every call.
  • You can revoke a grant from Synoro (Agents → Tools → External assistant access), disable MCP for the firm, or disable MCP writes while keeping reads. Revoking membership or company access takes effect on the next tool call. Third-party assistants may keep their own copies of data they already received; those copies are governed by that provider's terms and privacy policy, not this Agreement.

You are responsible for choosing a trustworthy assistant, reviewing what you authorize, and complying with your firm's policies and applicable law when sharing client or financial data with a third party.

6. Payment and Subscription

If you subscribe to a paid plan, you agree to pay all applicable fees described on the Synoro pricing page. Subscriptions renew automatically unless canceled in accordance with Synoro's policies.

7. Termination

Either party may terminate this Agreement at any time. Synoro may suspend or terminate access if you breach this Agreement or misuse the Services. Upon termination, your access will be revoked, but you may request a copy of your data.

8. Disclaimer of Warranties

The Services are provided “as is” without any warranties of any kind, express or implied. Synoro disclaims all warranties of merchantability, fitness for a particular purpose, and non-infringement.

9. Limitation of Liability

To the maximum extent permitted by law, Synoro shall not be liable for indirect, incidental, special, or consequential damages, including lost profits or data loss, arising out of your use of the Services.

10. Indemnification

You agree to indemnify and hold Synoro harmless from any claims, damages, or losses arising from your use of the Services or violation of this Agreement.

11. Governing Law

This Agreement is governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to its conflict of laws principles.
