Privacy Policy

This privacy policy explains what happens to your data when you use this bra size calculator. The short version: your measurements never leave your browser.

Measurements stay local

All sizing calculations — unit conversion, band resolution, cup resolution and sister sizes — run client-side in your browser. Your underbust and bust values are not transmitted to any server, are not logged, and are not included in any analytics event. If you use the calculator, an optional copy of your inputs may be kept in your browser's session storage so other pages on this site can highlight your size in a chart; it is deleted automatically when you close the tab.

Standard technical data

Like most websites, the hosting infrastructure may process minimal technical data (such as IP addresses in server logs) required to serve pages securely. No advertising identifiers are attached to your measurements or calculator usage.

Cookies

The site may use essential cookies or local storage for preferences such as theme and language selection. These are functional, not tracking, and contain no body data.

Changes

If this policy changes, the updated date above will change with it. Material changes will be reflected on this page before they take effect.
