Privacy policy
The short version: the tool does not send your measurements anywhere, because it has nowhere to send them.
What the tool does with your input
Calibration and sizing run entirely in your browser. No measurement, card image or ring dimension is transmitted to this site or to anyone else. There is no account, no login and no upload. Nothing you do with the sizer reaches a server.
What is stored on your device
Two items of local storage, both written by your own browser and readable only by this site. Neither is sent anywhere and neither identifies you.
arsz.calib.v1— your screen calibration, so you do not have to re-match your card on every visit. It holds a scale factor and a pixel ratio, nothing more.theme— whether you chose light or dark.
No cookies are set. Clearing your browser data removes both, and theReset to Default Size button on the tool clears the calibration on its own — worth using if you move between screens, because a calibration from one display is wrong on another.
Analytics
The site uses Google Analytics to count visits and see which pages are read. It records general technical information such as approximate region, device type and referring page. It is not connected to the sizer and receives none of your measurements. Any browser-level “do not track” or analytics-blocking setting is respected by the blocker rather than overridden here.
Advertising
The site may display advertising in future to cover hosting. If and when it does, ads will sit below the tool, never over it, and this section will name the provider before that happens.
Your rights
Because no personal data is collected by the tool itself, there is nothing held here to access, export or delete. For analytics data, use your browser’s cookie controls or an ad blocker. Questions to hello@actualringsize.com.
