2. Information We Do NOT Collect
Our free health calculators (BMI Calculator, Calorie Calculator, Ideal Weight Calculator, Body Fat Calculator, and Unit Converter) process all your inputs — including height, weight, age, gender, and body measurements — entirely within your web browser using JavaScript. This means:

- No health data is stored in any database.
- No health data is shared with any third party.
- Your calculator results are never recorded or tracked.
