Terms of Use

1. Agreement

These terms are an agreement between you and Farnor Labs, LLC ("Farnor Labs", "we", "us") about the Castiri Mac app and this website (together, "Castiri"). By downloading, installing or using Castiri, or by clicking Agree and Launch in the app, you accept these terms. If you don't accept them, don't use Castiri.

2. Your license

We give you a personal, non-exclusive, non-transferable, revocable license to install and use Castiri on Macs you own or control, for your own work or your organization's. You may not sell, rent, sublicense or redistribute Castiri, remove its notices, or reverse engineer it except where the law lets you despite this clause. We keep all rights we don't give you here.

3. Price

Castiri is free today. We expect to charge an annual fee in the future. If we do, we will announce the price on this website and in the app at least 30 days before it applies to you, and you will not be charged unless you agree to the price. The terms in force when you accept an update apply to that update. Nothing here obliges us to keep any version free, or to keep offering Castiri.

4. Beta software

Castiri is pre-release software. Features may change, break or be removed, and we may change how Castiri works with Claude Code and other tools. Keep backups of anything that matters.

5. Agents act on your Mac, and you are responsible for them

Castiri runs Claude Code agents that can read and edit files, and run commands, in the folders you give them, within the permission mode you pick. Some modes ask before each action; others do not, and "Skip all prompts" removes safety checks entirely. You choose the mode, the folder and the instructions, and you are responsible for what the agents do under them, for reviewing their work before you rely on it or ship it, and for keeping backups or using version control. Agents can be wrong. Their output is not professional, legal, financial or security advice.

6. Other services

Castiri works through other companies' software, under their terms, which are between you and them:

• Claude Code and your Claude account are Anthropic's. Your inputs and the files agents read are sent to Anthropic by Claude Code, under your account and Anthropic's terms and usage policies. Castiri is not made by or affiliated with Anthropic.
• Gaitro, if you open a Gaitro project from Castiri, is a separate service with its own terms.
• Models, plans and limits are set by your Claude plan, not by Castiri. Castiri shows usage as an estimate.

7. Your content

Your projects, inputs, instructions, roles and the files agents write are yours. Castiri has no server and we do not receive them, so we do not claim any rights in them. Teams you export are files you hand to other people, and what is in them is your responsibility.

8. Acceptable use

Don't use Castiri to break the law, to infringe other people's rights, to attack systems you don't have permission to test, or in a way that breaks Anthropic's usage policies. Don't point agents at data you aren't allowed to process.

9. No warranty

Castiri is provided "as is" and "as available", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, and that it will be uninterrupted or error-free.

10. Limit of liability

To the fullest extent the law allows, Farnor Labs and the people who work for it are not liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, lost data or business interruption, including loss caused by actions agents take. Our total liability for any claim relating to Castiri is limited to the greater of the amount you paid us for Castiri in the 12 months before the claim and US$100. Some places don't allow these limits, so they apply only as far as your law permits.

11. Ending

You can stop using Castiri at any time by deleting it. We may suspend or end your license if you break these terms. Sections that by their nature should survive, including 7 to 10 and 13, do.

12. Changes

We may update these terms. We will change the date at the top, and for a material change we will tell you on this site or in the app before it takes effect. Using Castiri after that means you accept the new terms.

13. Governing law and disputes

Arizona law governs these terms, without regard to its conflict-of-laws rules. Disputes will be brought in the state or federal courts located in Arizona, and you and we consent to their jurisdiction. This doesn't limit rights you have under consumer protection laws where you live that can't be waived.
