GDPR & CCPA Compliance Architecture
Privacy Policy & Data Sovereignty
bmrcalc.online operates on a strict client-side privacy architecture with zero third-party tracking cookies and zero server-side storage of personal health parameters.
1. Client-Side Computational Isolation
All anthropometric calculations—including your age, biological sex, body weight, height, and activity level—are processed entirely in your web browser via client-side JavaScript. None of your entered personal health parameters are ever transmitted to our web servers, logged in server access files, or sold to third-party data brokers.
2. Local Storage Usage
To enhance user convenience across consecutive visits, our tools optionally utilize your web browser's native localStorage interface under the key bmrcalc_user_prefs_v1. This stores solely your last selected unit system (Metric vs Imperial) and nominal calculation inputs so you do not have to re-enter your dimensions. This data resides solely on your physical device and can be cleared at any time via your browser settings.
3. Zero Third-Party Advertising Trackers
We do not embed third-party surveillance cookies, fingerprinting pixels, or behavioral advertising trackers. Our hosting infrastructure is deployed edge-first via Cloudflare Pages, utilizing standard anonymized edge telemetry solely for security DDoS prevention and Core Web Vitals performance optimization.
