Terms of Service

Turnstone (operated by Crow Inc.)
Effective Date: August 21, 2026

These Terms of Service govern your use of the Turnstone desktop application and the website at myturnstone.ai, provided by Crow Inc. ("Turnstone," "we," "us"). By using Turnstone, you agree to these terms.

1. The Service

Turnstone is a local-first desktop application that lets you work with AI agents on your own files and, optionally, on third-party services you connect (such as Gmail). Turnstone performs actions on your behalf based on the instructions you give it.

Turnstone does not include AI model access. You supply it: an existing ChatGPT or Claude subscription, your own OpenAI, Anthropic, or OpenRouter API key, or a model you run locally. Turnstone also offers a set of free open source models for people who do not have their own access. Those run through OpenCode Zen and are subject to its terms in addition to these.

2. Your Account

You are responsible for keeping your account credentials secure and for all activity under your account. You must provide accurate information when you register.

3. Your Model Provider

When you use your own subscription or API key, your relationship with that provider is direct. Their terms, pricing, usage limits, and data policies govern it, not ours. You are responsible for holding valid access to whichever model you point Turnstone at and for complying with that provider's terms.

We do not control a provider's availability, pricing, rate limits, or output, and we are not responsible for changes they make. If your subscription or key stops working, the parts of Turnstone that depend on it stop working with it.

4. Connected Services

When you connect a third-party service, you authorize Turnstone to access that service on your behalf to carry out your requests. These connections are managed through our integration provider, Composio, which handles the authorization on our behalf. Our Privacy Policy sets out what that involves and what data moves where. Your use of each connected service remains subject to that service's own terms. You can disconnect a service at any time.

5. Acceptable Use

You agree not to use Turnstone to violate any law, infringe others' rights, access accounts or data you are not authorized to access, or attempt to disrupt or reverse-engineer the service. You are responsible for the tasks you direct the agent to perform.

6. AI Output

Turnstone uses AI models that can make mistakes. Output may be inaccurate or incomplete, and you are responsible for reviewing it before relying on it. Turnstone is a tool and does not provide legal, financial, or professional advice.

7. Your Content

Turnstone works on files stored on your own computer. You own them, and we do not receive or store them. We claim no license to your files, your local memory, or your chat history.

Where you send content to us directly, such as a support message or a form submission on our website, you grant us only the limited rights needed to respond to you and operate the service.

8. Intellectual Property

Turnstone and its underlying software are owned by Crow Inc.

9. Disclaimers

Turnstone is provided "as is" without warranties of any kind, to the fullest extent permitted by law.

10. Limitation of Liability

To the fullest extent permitted by law, Crow Inc. will not be liable for indirect, incidental, or consequential damages arising from your use of Turnstone.

11. Termination

You may stop using Turnstone at any time. We may suspend or terminate access if you violate these terms.

12. Changes

We may update these terms from time to time. Continued use of Turnstone after changes take effect constitutes acceptance of the updated terms.
