Cookie Policy

We do not use advertising or cross-site tracking cookies. The storage we use keeps you signed in, remembers your preferences, and measures aggregate traffic.

• Authentication session — set when you sign in so you stay signed in between visits. Removing it signs you out.
• Preference and cache storage — local browser storage holding your last verified site settings, feature flags, and recently loaded stats so the app still renders if a request fails.
• Analytics — the hosting platform's privacy-focused analytics records page views, referrer, device type, and coarse country in aggregate.
• Map tiles — map imagery and fonts are cached by your browser for performance.

If you sign in with Google, Google sets its own cookies during the sign-in flow under its own privacy policy. Fonts and map tiles are requested from third-party CDNs, which can see your IP address as part of serving the request.

• Clear cookies and site data in your browser settings to remove everything we have stored.
• Block cookies for this domain — the public calculator and guides still work, but sign-in and saved mines will not.
• Browser or extension tracking protection and Do Not Track settings are respected by our analytics provider's aggregate measurement.

For how the resulting data is handled, see the Privacy Policy.
