Terms of Use
Last updated: October 28, 2026
1. Who offers tatu
Tatu is offered by João Alonso, an individual based in Brazil ("we"). By installing or using the tatu program, its app, or the services at tatu.codes, api.tatu.codes, get.tatu.codes and relay.tatu.codes, you agree to these terms and to the Privacy Policy. If you do not agree, do not use tatu.
2. Licence
Tatu is free. We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use it for your own work, including commercial work. We keep all other rights. You may not sell, sublicense or redistribute tatu, or reverse engineer it except where the law allows it despite this restriction.
3. What tatu does
Tatu is a coding agent: at your request, a model reads files, edits code and runs commands on your computer. Models make mistakes. You are responsible for reviewing what tatu does, for the projects you run it in and for keeping backups. See Security and trust.
4. Providers and accounts
Tatu works with model providers and other services that you sign in to with your own accounts and keys. Their terms, limits and prices apply to you, and so do any charges they make. Signing in to a provider with a subscription account is subject to that provider's terms; check that your use is allowed. We do not control those services and are not liable for them.
5. Services we run
The relay, the model catalog and the update server are offered free of charge, as they are, with no promise of availability. We may change, limit or stop any of them at any time.
6. Acceptable use
You agree not to:
- use tatu or its services for anything illegal, or to harm others;
- attack, overload or probe our services, or try to get around their limits;
- access the sessions or devices of other people without their permission.
We may block access to the services for anyone who breaks these rules.
7. Your content
Your code, prompts and sessions are yours. We claim no rights to them. Tatu's relay only routes messages; what a session says travels encrypted end to end, and the relay cannot read it. What the model providers do with your content is governed by their terms.
8. Donations
Donations through Ko-fi are voluntary. They give no right to features, support or any service, and Ko-fi's terms apply to them.
9. No warranty and limit of liability
To the extent the law allows, tatu and its services are provided "as is", without warranties of any kind, and we are not liable for indirect or consequential losses, for lost data or profits, for changes the agent makes to your files or systems, or for charges from third-party providers. Our total liability for any claim is limited to what you paid us for tatu, which is zero. Nothing in these terms removes rights that the law does not allow to be waived, such as those of consumers under the Brazilian Consumer Defense Code.
10. Ending, changes and governing law
You can stop using tatu at any time by uninstalling it. We may end your licence if you break these terms. We may update the terms; the date at the top shows the latest version, and using tatu after a change means you accept it. These terms are governed by the laws of Brazil. Disputes go to the courts of the place where the author lives, except where consumer law gives you the right to sue where you live.
