What health tools does GoChronos offer?

GoChronos Health tools include a BMI Calculator and an all-in-one Metabolic Calculator covering BMR, TDEE and daily calorie & macro targets. All tools use clinically recognised formulas and run entirely in your browser — no data is uploaded or stored.

Are the health tools medically accurate?

The tools use WHO and NIH-endorsed formulas: BMI uses the standard weight/height² formula, BMR uses the Mifflin-St Jeor equation. They are accurate for population-level estimation but are not a substitute for professional medical advice.

Is my health data private?

Yes. Your weight, height, age and sex are processed locally and never sent to any server. GoChronos does not collect or store health data.
