What the app does
This calculator processes the measurements you enter in your browser to estimate body fat and calculate ratios. Calculations run locally, and no account is required. Google Analytics runs only with your explicit consent. The app does not use advertising or personalized ads.
Browser storage and consent
Until you consent, your entries, history, and settings remain in the current browser session. If you allow storage, the app saves your current measurements, history, settings, and temporary restore data in your browser. Consent cookies record your choices for up to one year. Your measurement data is not sent to the controller.
You can withdraw consent at any time in Settings. If you turn off storage, the app immediately deletes its saved data from this browser. This processing is based on your consent under Article 6(1)(a) GDPR. You can also use the calculator without allowing storage.
Google Analytics
If you consent to Google Analytics, Google Ireland Limited measures website usage. Analytics loads only after you give explicit consent. See Google's privacy policy for details.
Clipboard and exports
If you choose to copy a template or result, your browser uses its clipboard function. JSON backups and CSV files are created locally on your device, and imports are processed locally.
Hosting and technically necessary server data
When the hosting provider delivers this website, it may process connection data such as your IP address, the date and time, and the requested resource in server logs. This is necessary to provide and secure the website. The hosting provider's configuration determines how long these logs are retained.
Your rights
Subject to applicable legal requirements, you may request access, rectification, erasure, restriction of processing, and data portability, or object to processing. You may withdraw consent at any time, effective for the future. You may also lodge a complaint with a data protection supervisory authority.
Updates
This policy may be updated if the app or its data processing changes.
