What does Calorie Calculator do?
It estimates daily calorie needs based on your age, sex, weight, height, and activity level.
How accurate is the result?
It uses standard, widely published formulas, but it's a general estimate, not a medical assessment — for guidance specific to your health, consult a doctor or qualified professional.
Is my data sent anywhere?
