Is NutriCalc Pro really free?

Yes, completely free. No signup required, no premium tier, no hidden charges. The site is supported by display advertising.

Where does the nutritional data come from?

All food nutrition data is sourced from the USDA FoodData Central database — the gold standard in food nutrition data used by healthcare professionals worldwide.

Is my health data stored on your servers?

No. All data you enter (weight, height, calorie goals) is stored locally in your browser using localStorage. It never leaves your device.

Can I request a new food or feature?

Absolutely — we welcome feature requests! Send us an email with the subject "Feature Request" and we'll consider it for a future update.

The calorie results seem different from another calculator — why?

Minor differences between calculators are normal and usually due to different data sources or rounding methods. Our data is sourced directly from USDA FoodData Central for maximum accuracy.
