Privacy

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

• Calculators run entirely in your browser. The weight, height, age, and medication-timeline 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.
• 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.
