Your numbers stay on your phone.
No accounts. No cookies. No servers receiving your weight. The calculations run inside your browser tab. We genuinely can't see what you typed — there's nowhere for it to go.
We're not selling you a prescription.
No telehealth partnerships. No affiliate links inside the calculators. If we ever add affiliate links anywhere, they'll be labelled — and never inside the medical math.

Every calculator exports a clean, doctor‑readable PDF. Walk in with the citations and your projection. Walk out with a plan you both understand.
