How does Any2File protect my privacy with Body Fat Calculator?

All algorithms execute locally on your device within your browser sandbox using compiled WebAssembly and native Web APIs. Your files, documents, and inputs never touch external cloud servers.

Our calculators utilize peer-reviewed formulas including the Mifflin-St Jeor and revised Harris-Benedict equations for BMR/TDEE, and official World Health Organization (WHO) and CDC metrics for BMI classification.
