Privacy policy

This policy explains which information Fast & Rational processes when you use the site and why.

The public interaction checker does not require an account. Your selected medicines, conditions, drug groups, and age setting are sent to the server only to find interactions. Fast & Rational does not maintain a user database for these selections.

If you enable AI mode, you sign in with Google. Your Google profile name, email address, and profile image are processed to maintain the browser session. Fast & Rational does not maintain a separate user profile database.

Your AI question and selected health context are sent to Google Gemini to generate a response. Do not enter identifiable or sensitive patient information.

Google Analytics may process usage data through cookies and similar technologies, including visited pages, clicks, approximate location, device, and browser information. We use this data to understand the product and monitor errors. Fast & Rational does not sell personal information.

External destinations such as LinkedIn and Frontiers apply their own privacy policies. Contact us through our LinkedIn page for a privacy request.
