What we collect

reaso.ai collects minimal data. We do not require user accounts. When you use the stress-test tool, your claim text is sent to our API for processing. We do not store claim text after analysis is complete. We use standard web server logs (IP address, user agent, timestamps) for security and abuse prevention.

Third-party services

We use the following third-party services:
Anthropic (Claude API) — processes claim analysis. Subject to Anthropic's privacy policy.
Serper API — searches for evidence. Subject to Serper's privacy policy.
AWS (Amazon Web Services) — hosts the site and API. Subject to AWS's privacy policy.

Cookies

reaso.ai does not use tracking cookies or analytics. We use browser localStorage to save your analysis results locally on your device. This data never leaves your browser.
