Privacy Policy

Last updated: 13 November 2026

1. No personal data collected

Percentage Calculator does not ask for your name, your email address, or any personal information. There is no account, no sign-up and no login. We do not collect, store or sell personal data about our visitors.

2. Your numbers stay in your browser

When you type numbers into a calculator, they are worked out on your own device in your browser. They are never sent to our server or to any other server, and they are never stored, shared or seen by anyone.

3. Cookies

This site uses a cookie-consent banner. Your choice (Accept or Decline) is stored in your browser's local storage so the banner does not keep asking. No other cookies are set by Percentage Calculator itself. If you decline, only non-personalised advertising is shown.

4. Advertising — Google AdSense

This site shows advertising from Google AdSense. Google and its partners may use cookies to show ads based on your visits to this and other websites. You can opt out of personalised advertising at Google Ads Settings or at aboutads.info/choices. The AdSense script is loaded on every page; it renders no ads by itself — ads appear only when Auto ads is enabled in the AdSense account.

5. Third-party services

Percentage Calculator loads no third-party tracking, analytics or social-media scripts. The only third-party code is the Google AdSense script described above.

6. Children's privacy

Percentage Calculator is a general-purpose tool site. We do not knowingly collect personal information from children under 13, or from anyone at all — the site collects no personal data from any visitor.

7. Changes to this policy

If this policy changes, the new version will be posted on this page with a new “last updated” date. Continued use of the site after a change means you accept the new policy.
