Privacy Policy
Short version: your numbers never leave your device.
What we collect
Calculator inputs: none. Every calculation runs entirely client-side in your browser. The age, weight, height and other values you enter are never transmitted to, logged by, or stored on any server.
Accounts: there are none. We ask for no email and no sign-up. We set no cookies and use no localStorage tracking.
Analytics & third parties
Analytics: none. We run no analytics, no tracking pixels, and no advertising. We do not profile visitors.
Fonts: pages load web fonts from Google Fonts. Your browser’s request to Google to fetch those font files exposes your IP address to Google under Google’s privacy policy; no cookies are set by these requests and no personal data is sent by us.
Hosting: the site is served as static files by Cloudflare Pages, which may process standard request metadata (e.g. IP address) for security and delivery under Cloudflare’s privacy policy. We do not receive or store this data.
If we ever add analytics or ads, this section and a cookie/consent notice will be updated before they go live.
Your rights
Because we hold no personal data about you, there is nothing for us to access, export or delete. Data handled by Google Fonts or Cloudflare is governed by their respective policies.

We will update this page if our data practices change. Questions are welcome at the address below.
