Estimate calories, macros, and body metrics with informational calculators that never replace medical advice — consult a professional for decisions. The calorie tool targets intake from weight, height, age, and activity, like roughly 2,200 kcal for an active 70 kg adult. The macro splitter divides that into protein, carbs, and fat grams, while body-metric trends track change over weeks. For example, 70 kg at 175 cm gives a BMI of 22.9. Each tool page answers common questions in its FAQ, private and offline.

Yes, with care — all health tools are free with no signup and calculate locally so data stays private. The BMI Calculator tracks change over weeks on your device without uploading weight history. Only articles need internet. Remember 70 kg at 175 cm gives BMI 22.9, still just an estimate.
To keep data private, open Calorie Calculator once while online and leave the tab open. Most health math then runs offline locally, so 70 kg at 175 cm still yields BMI 22.9 and 2,200 kcal targets still show. Closing the tab erases entries. No install is needed; consult professionals for decisions.
