Privacy Policy

Last updated: August 2026.

What we collect

The numbers you enter into our calculators (height, weight, age, activity level) are processed entirely in your browser using JavaScript. They are never sent to, or stored on, our servers. Refreshing the page clears them completely.

Cookies and analytics

Wellnum may use standard, privacy-conscious analytics to understand overall traffic patterns (such as which pages are visited and roughly how many people visit), and may in future display advertising through a network such as Google AdSense. Advertising partners may use cookies to serve relevant ads; you can control cookie behaviour through your browser settings or an ad-preferences page such as Google's Ads Settings.

Third parties

We don't sell personal data, because we don't collect any beyond basic, aggregated traffic analytics. If that changes, this policy will be updated with the date above revised accordingly.
