Review standards, sourcing & privacy

How we choose formulas, write guides and protect the little data you enter.

Review standards

Every calculator names its formula and limits. Guides are written for general adults, reviewed for clarity and avoid diagnosis, dosage or treatment claims. We revisit content when guidance changes.

Educational only

Data sourcing

Methods come from published equations: Karvonen, Tanaka, Mifflin-St Jeor, WHO adult BMI bands and public physical-activity and sleep guidance. Estimates carry margins that we show.

Published methods
