YOUR PRIVACY GUARANTEE
Privacy Policy.
Effective Date: September 6, 2026
Summary of Our Privacy Guarantee
- Zero Health Tracking: Your age, biological sex, height, weight, and body fat inputs are processed 100% in your local web browser.
- No Server Transmission: Calculation inputs are never transmitted across the network, saved in logs, or stored in any database.
- No Third-Party Ad Trackers: We do not load third-party ad networks, surveillance scripts, or cross-site tracking beacons.
- Theme Preference: The only piece of information stored on your machine is your chosen light or dark theme inside standard browser localStorage.
1. Information We Do Not Collect
Unlike most online health utilities, BMR Calculator Online (https://bmrcalculatoronline.in) does not require user accounts, email addresses, phone numbers, or profile creation. When you adjust values in our calculator widget:
- All arithmetic is executed via JavaScript on your client CPU.
- Refreshing or closing the browser tab immediately discards your entered values.
- We have zero knowledge of who uses the calculator or what figures are entered.
2. Local Storage Usage
Our website uses browser localStorage solely to remember your color scheme preference (bmr-theme: "dark" or "light"). This prevents visual flickering ("theme flash") when navigating between pages. You can clear this key at any time through your browser settings.
3. Hosting & Infrastructure Logs
When your web browser requests static files (HTML, CSS, images) from our server, basic network communication logs are generated by the hosting infrastructure (such as IP address, user-agent string, and requested URL). These standard HTTP logs are used solely for DDoS mitigation, caching, and infrastructure security.
4. External Links
Our website provides citations to scientific journals and reference publications (such as PubMed and PubMed Central). Clicking these links connects you to third-party domains which operate under their own independent privacy notices.
