Your measurements stay with you

Privacy, in plain language.

The calculator runs in your browser. It does not require an account, camera access, a card photograph, or payment details. Measurement inputs are not sent to an application server.

What this website stores

If you calibrate the screen, the site saves the scale and its calibration method in your browser’s local storage, together with reported screen dimensions, pixel ratio, and visual zoom. This helps detect when calibration needs checking. Reset it from the calibration dialog, or clear this site’s browser data.

Measurement results stay in memory during the visit. Copying a result writes it to your clipboard only when you choose Copy. Printing uses your browser’s print dialog. Your selected measurement tab and print paper size may appear in the URL.

Fonts, analytics, and hosting

Fonts and application assets are served with the site. This version contains no analytics scripts, advertising pixels, or third-party tracking cookies. A hosting provider may process ordinary request information such as IP addresses and browser headers to serve and secure the site.

External links and email

Reference links take you to other websites, which have their own privacy practices. If you email hello@ringsizecalculator.com, your email provider and the recipient’s mail service process that message. Do not include card details or other sensitive information.
