Privacy policy

• No account, no name, no email address, and no sign-in of any kind.
• No advertising, and no third-party trackers unless analytics is configured and you consent (see Analytics below). With no configuration, nothing is tracked at all.
• No photos, video, or camera access in this stage — the screen sizer uses sliders and an SVG circle, not a camera.
• No measurement is stored on a server. If you close the page, your result is gone.

The tool runs entirely in your browser: card calibration, circle sizing, unit conversion, and chart lookup all happen on your device. The hosting provider (Vercel) may log standard technical information needed to serve the page, such as the page requested and the time of the request, as part of operating the website. That is not a measurement record and cannot be linked to a ring size, because no size ever leaves your device.

The site includes a privacy-aware analytics framework (Google Analytics 4), but it is inactive unless two conditions are both met: a measurement ID is configured by the site owner, and you accept analytics in the consent banner. If either condition is not met, no analytics script loads and no analytics event is sent. When active, analytics records only bucketed usage — which tool was used, by what method, on what kind of device, and whether the measurement completed — never your raw diameter, circumference, or ring size, and never contact details, photos, or fingerprints. Advertising tracking is always off. Your consent choice is stored only on your own device, and declining loads nothing.

This site sets no advertising cookies. Analytics cookies are set only by Google Analytics, and only after you accept analytics as described above. If a future stage adds advertising or an account system, this page will be updated before that feature goes live, and the change will be stated here in plain language.

If this policy changes, the new version will be published on this page. The standing promise — no account, no server-side measurement storage, and no analytics without configuration and consent — will not be silently removed; any change to it will be called out here.
