Privacy Policy

Last updated: 2026-06-07

1. What we collect

AllFreeCalculator does not require you to create an account or submit personal information to use any of the tools on the site. Every calculator runs entirely inside your browser — the numbers you type are never transmitted to our servers.

2. Cookies and local storage

We use a single browser localStorage entry to remember your dark/light mode preference. We do not use tracking cookies of our own.

3. Analytics and advertising

We may use privacy-respecting analytics and may display advertising (for example, Google AdSense) to keep the site free. These third parties may set their own cookies and collect aggregated, non-personally-identifiable usage data subject to their own privacy policies. You can opt out of personalised ads via Google Ads Settings.

4. Children

This site is intended for general audiences. We do not knowingly collect personal information from children under 13.
