Privacy

Short version: your numbers never leave your browser.

All calculations on KcalMath run entirely in your browser. Age, weight, height, body fat and every other input are never transmitted to our servers, never stored, and never shared. There are no accounts and no tracking cookies set by us. Our hosting provider (Cloudflare) may collect standard aggregate request logs (IP, user agent) to serve and secure the site; see Cloudflare's privacy policy for details. If we later add privacy-preserving aggregate analytics, this page will say so first.
