If you allow analytics

We record which pages are visited, what is typed into our search box (with emails and long numbers removed), which calculators are opened, and general context: country (from our host, not your IP address), device type and browser. A random ID in your browser lets us tell new visitors from returning ones. We do not record what you type into calculators, and we use no advertising trackers or fingerprinting.

Raw events are deleted after 90 days.

If you create an account

We store your email, an optional display name, your preferences, and the pages you save. Anonymous usage is only linked to your account if you turn that on in your account settings. You can download everything we hold or delete your account at any time from your account page.

Calculators

Calculations run in your browser. Saved results stay in your browser unless you choose otherwise.
