Privacy Policy

Percentage Calculator (the "Service") respects your privacy and processes only the minimum information described below.

1. Information we collect

The Service works without an account or login. The numbers you type are calculated only in your browser. They are not sent to our server and are not written into any link. The Service remembers only which calculation tab you used last, on your own device. When you use the share buttons, only the page address and a short text without your numbers are shared, and only with the people you choose.

2. Cookies and similar technologies

The Service may use cookies and your browser’s local storage to remember your language and last calculation tab, to show ads and to understand how the Service is used. You can refuse or delete them in your browser settings; some features may not work as expected if you do.

3. Advertising (Google AdSense)

The Service shows ads through Google AdSense. Google and its partners may use cookies to serve ads based on your previous visits to this and other websites. You can learn more and change your preferences in Google Ad Settings.

4. Statistics

To improve the Service we may use Google Analytics (GA4) and our own aggregate counters that keep only daily totals per language (page views, calculations, star ratings). The numbers you calculate are never part of these counts, and none of this identifies you personally.

5. Contact

If you have any questions about this Privacy Policy, please contact the site operator.

6. Effective date

This policy is effective as of October 22, 2026.
