None whatsoever. BodyComparison is a pure static web utility that executes 100% inside your web browser. No accounts are required, no background APIs are contacted, and no names or measurements ever leave your device. For convenience, your active subjects are cached locally in your browser's private localStorage so they remain available if you refresh the page.
