What you enter
All calculators run in your browser. The values you type are not sent to us or to anyone else. ScaleCalculator has no accounts, no sign-up and no forms.
Cookies and local storage
The site sets no cookies. The on-screen scale ruler remembers your calibration in
your browser's local storage (key sc_ruler_cal) once you move its slider, so you do not need to
calibrate again. It stays on your device and you can clear it in your browser settings.
Hosting and statistics
The site is hosted on Cloudflare. To deliver pages, Cloudflare processes technical request data such as your IP address, as described in the Cloudflare privacy policy. We use Cloudflare Web Analytics to count page views. It does not use cookies or local storage and reports only aggregated figures such as visited pages, referrers, browsers and countries.
Advertising and tracking
There is no advertising and no cross-site tracking on ScaleCalculator.
