Privacy

The short version: this site is built to know as little about you as possible.

• The tools run entirely in your browser. The age, body-fat percentage, and measurement values you enter are never sent to a server — there is no server. They exist in your browser tab and, if you use the share feature, in the URL you choose to copy.
• Share links contain your inputs. That's what makes them work. Only share a results URL with people you're comfortable seeing those numbers.
• No accounts, no cookies set by us, no email capture, no uploads. The results interpreter asks you to type numbers off your report; it never asks for the report itself.
• Analytics: if enabled, we use Cloudflare Web Analytics, a cookieless, privacy-focused counter that does not track individuals across sites.
• Affiliate links: if you click a marked sponsored link, the destination site sets its own cookies under its own policy.
