Terms of Service

Last updated: June 4, 2026

These Terms of Service ("Terms") govern your access to and use of Sinatra, including our website, app, and the automated coding agent that works on the issues you assign it (together, the "Service"). By using the Service, you agree to these Terms. If you use Sinatra on behalf of an organization, you agree on its behalf and confirm you have the authority to do so.

1. What Sinatra does

Sinatra is an automated coding assistant. You connect it to your development tools and assign it issues or tasks. It reads the relevant code, proposes changes, and opens pull requests on a branch. Sinatra works in branches and opens pull requests only. It does not merge, deploy, or release anything — those steps are always yours.

2. Your account

You are responsible for your account, for keeping your login secure, and for everything that happens under it. Provide accurate information and keep it current. If you add team members or connect an organization, you are responsible for their use of the Service and for making sure they follow these Terms.

3. Acceptable use

You agree not to:

• use the Service to build or distribute anything illegal, infringing, or harmful;
• connect repositories, accounts, or data you are not authorized to access;
• attempt to disrupt, overload, reverse-engineer, or gain unauthorized access to the Service;
• resell or misrepresent the Service.

We may suspend or terminate access that breaks these rules.

4. Your content and repositories

You keep all rights to your code, repositories, and other content you connect or provide ("Your Content"). You grant Sinatra a limited license to access, store, and process Your Content only as needed to operate the Service and perform the tasks you ask it to do. You are responsible for having the rights to connect whatever you connect, and for your use of any code the Service helps you produce.

5. Your responsibility for the code

Sinatra is an automated assistant, and everything it produces — code, diffs, pull requests, comments, and suggestions — is a draft for you to review. You are solely responsible for reviewing, testing, and verifying any output before you merge, deploy, or otherwise use it. You decide what gets merged and shipped, and you are solely responsible for the code you ship and all of its consequences — including bugs, security vulnerabilities, data loss, outages, downtime, intellectual-property and licensing issues, and regulatory or compliance matters. Nothing Sinatra produces is reviewed, approved, or guaranteed by us, and you should not rely on it without your own review.

6. Third-party services and your own keys

The Service connects to third-party tools and may rely on third-party model providers and infrastructure to do its work. If you connect your own model keys or accounts, your use of them is governed by those providers' terms, and you are responsible for any charges and for keeping your keys valid. We are not responsible for third-party services, and their availability and behavior are outside our control.

7. Plans and billing

Sinatra offers free and paid plans. On a paid plan, you agree to pay the fees described when you sign up, along with any applicable taxes. Fees are billed in advance and, except where required by law, are non-refundable. You can cancel at any time, and cancellation takes effect at the end of your current billing period. We may change our plans or pricing, and we will give reasonable notice before a change affects you.

8. Our intellectual property

The Service, including our software, branding, and content — but not Your Content — belongs to Sinatra and is protected by law. These Terms do not transfer any of our intellectual property to you beyond the right to use the Service as described.

9. Disclaimers

The Service and all output are provided "as is" and "as available," with no warranties of any kind, whether express or implied. We do not warrant that the Service or its output is accurate, complete, secure, reliable, fit for any particular purpose, non-infringing, or free of errors or interruptions. You use the Service and everything it produces at your own risk.

10. Limitation of liability

To the fullest extent permitted by law, Sinatra and the people and companies behind it will not be liable for any damages of any kind — including direct, indirect, incidental, consequential, special, or exemplary damages — arising out of or relating to the Service or any code or output it generates. This includes bugs, security vulnerabilities, lost or corrupted data, lost profits, business interruption, and downtime, and it applies regardless of the legal theory and even if we have been advised of the possibility. Your sole and exclusive remedy for any dissatisfaction with the Service is to stop using it. Where the law does not allow some liability to be excluded, our liability is limited to the smallest amount the law permits.

11. Termination

You can stop using the Service at any time. We may suspend or end your access if you breach these Terms or if we need to for legal, security, or operational reasons. When access ends, the rights granted to you under these Terms stop, and any sections that by their nature should survive — including ownership, disclaimers, and limitation of liability — continue to apply.

12. Changes to these Terms

We may update these Terms from time to time. When we do, we will revise the date at the top. If you keep using the Service after the changes take effect, you accept the updated Terms.
