Privacy notes

• Your key never leaves your browser except in direct requests to Anthropic.
• This site has no backend, no analytics, no telemetry. Open the browser network tab and verify.
• To remove the key entirely: click clear above, or just clear site data in your browser.
• If you fork or self-host this site, the same applies — your fork has no backend either.
