Cookie Policy

What we store on your device

• Sign-in session (essential). Keeps you signed in so you don't have to log in on every page. Cleared when you sign out.
• Your settings (essential). Saved in your browser's local storage: theme, kids or adult mode, units, and whether you've seen the tutorial.

What we do not use

• Advertising or retargeting cookies
• Social media tracking pixels
• Third-party analytics or session recording
• Cross-site profiling of any kind

Your choices

Because everything above is strictly necessary to run the app, there is nothing to opt out of — we don't ask for tracking consent because we don't track. You can clear this storage any time through your browser settings; you'll simply be signed out and your look-and-feel settings will reset.

Third-party requests

The site loads fonts from Google Fonts, which involves a request to Google's servers but sets no cookies on our behalf. Sign-in with Google sets cookies on Google's own domain under Google's policies.
