Privacy Policy

Last updated: October 25, 2026.

What we collect

The calculators on this site run entirely in your web browser. The numbers you type are never sent to, or stored on, a server. We do not ask for accounts, names or email addresses to use the tools.

Cookies and advertising

This site is supported by advertising. When advertising is enabled, we use Google AdSense, and Google and its partners may use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalized advertising by visiting Google Ads Settings, and you can learn how Google uses data from sites that use its services on Google's policies pages.

We may also use basic, privacy-respecting analytics in future to understand which calculators are useful. If that changes, this policy will be updated first.

Third-party links

Links to other websites are provided for convenience. We are not responsible for the privacy practices or content of those sites.
