Privacy Policy

Last updated: September 19, 2026

This page explains what information this app collects, how it's used, and how it's protected. It's written in plain language rather than legal boilerplate — if anything here is unclear, use the contact info at the bottom.

Information We Collect

None. There are no accounts, no sign-in, and no database. The numbers you enter into a calculator (income, height, weight, an IP address and prefix, and so on) are used only to compute the result shown to you, and are never sent to or stored on the server.

Third Parties

A small number of third-party services are used:

• Google Fonts — pages load typefaces from Google's font servers, which may log the IP address and browser information of that request. See Google's Privacy Policy.
• Advertising (Google AdSense) — this site may display ads served by Google AdSense. Google and its partners may use cookies to serve ads based on your visits to this and other sites. You can review or opt out of personalized advertising at Google Ads Settings, and learn more at How Google uses information from sites that use our services.

We do not sell your information to anyone.

Cookies

This site does not set any cookies of its own. If advertising is active, Google may set cookies for ad delivery and measurement, as described above.

Children's Privacy

This site is not directed at children under 13, and we do not knowingly collect information from children under 13.

Changes to This Policy

This policy may be updated from time to time. Material changes will be reflected by updating the "Last updated" date above.
