The short version

Privacy Policy

CalcJoy doesn't require an account and doesn't ask for personal information. Calculations happen entirely in your browser.

What we store on your device

  • Favorites, pinned, and recently used calculators (localStorage).
  • Your theme preference (light, dark, auto).
  • Optional per-calculator history for convenience.

This data never leaves your device. Clearing your browser storage removes it instantly.

Analytics & ads

If we add analytics or advertising in the future, we'll choose privacy-respecting providers and update this page first.
