Waitlist email

If you join the waitlist on this site, we only use your email address to contact you about Zirn early access and product updates. You can ask us to remove your email at any time.

AI and your API keys

When you connect a Mistral API key in Zirn, that key stays on your device and is used only to send requests you initiate. Zirn does not store your API key on our servers.

Third-party services

If you choose to use Mistral or another AI provider, your prompts and relevant context are sent directly to that provider under their terms and privacy policy. Zirn does not intercept or retain those requests on our servers.
