1. 100% Client-Side Computation Guarantee
When you utilize the BMI Calculator, BMR Calculator, Body Fat % Estimator, or any other tool on this website, all calculations are executed strictly within your browser's local JavaScript runtime. None of your inputs (height, weight, age, sex, body fat measurements) are ever transmitted to our servers, logged, stored, or processed externally.
2. Local Storage Usage
We use browser localStorage solely for non-sensitive interface preferences, specifically:
- Your selected visual theme (Light Mode vs. Dark Mode).
No personal health data, calculations, or session identifiers are stored in cookies or tracking tokens.
3. Third-Party Trackers & Advertising
We do not deploy invasive third-party cross-site advertising trackers, fingerprinting scripts, or data-broker analytics. Our hosting environment provides high-security encryption (HTTPS/TLS) across all assets.
4. Contact Information
If you contact us via our contact form, your name and email are used solely to reply to your inquiry and are never sold or used for marketing distribution.
