Calculations stay on your device

All calculators run in your browser. The numbers you enter are not sent to us. If you use My shopping list, the list is saved in your browser's local storage on your own device so it is still there when you come back. It never leaves your device unless you share it yourself, and you can delete it at any time with “Clear list” or by clearing your browser data.

Hosting

This website is delivered by Cloudflare, Inc. To deliver pages securely, Cloudflare processes technical data such as your IP address and browser type. Legal basis: our legitimate interest in a secure, fast website (Art. 6(1)(f) GDPR).

Cookies, analytics and ads

We currently set no cookies (the shopping list uses local storage only to keep the list you asked us to keep) and use no analytics or advertising. Fonts are served from our own server, not from Google.

Your rights

You have the right to access, correct, delete and restrict processing of your data, to object, to data portability, and to complain to a data protection supervisory authority.
