Privacy Policy
100% Local Processing & Privacy
We believe your health data should belong solely to you. All fitness measurements, age, weight, height, and unit preferences are processed instantly inside your browser and stored exclusively in your local storage (localStorage). No personal data is ever collected, tracked, or transmitted to any external servers.
Our privacy-first commitment means you can calculate and track your metrics with absolute peace of mind. Here is a breakdown of how we manage data:
1. Local Storage Usage
We use standard browser-based local storage to save your input values (such as weight, height, age, and gender) to synchronize them across our different calculators. This prevents you from having to re-enter your biological stats each time you switch calculators or return to our site.
2. Zero Server Transmissions
Unlike traditional apps, there is no sign-up flow, user account database, or cloud synchronization. All calculator logic runs locally on your machine. Absolutely no biological data, metrics, or input details are sent to our hosts or any third-party services.
3. No Trackers or Analytics
We do not implement trackers, advertising pixels, or analytics cookies that build profiling databases. Your browsing behavior and calculated inputs remain completely anonymous and isolated.
4. Complete Control
Since your details are saved exclusively in your browser, you have complete control over them. You can delete your saved metrics at any time by clearing your browser cache and site data, or by using the browser developer tools to clear local storage.
