Privacy policy

Effective October 30, 2026

1. What we don't collect

The site has no sign-up, login or contact form, and does not store names, emails or phone numbers. Everything you type into a calculator stays in your browser. Example forms on the site show a preview and send nothing.

2. Stored in your browser

Small settings such as a game's best score are saved in your browser's localStorage. They are never sent to us, and clearing site data removes them.

3. Analytics and ads

  • We use Google Analytics to count visits. It collects anonymous data such as pages viewed, device type and approximate region through cookies.
  • We use Google AdSense. Google may use cookies to show ads based on your visits to this and other sites.
  • You can turn off personalized ads in Google Ad Settings and block cookies in your browser.

See the Google Privacy Policy for how Google handles this data.
