Using the calculators: you can use every calculator without signing in. The numbers you enter stay in your browser and are not sent to us.

Visit statistics: we count visits with an anonymous ID stored in your browser so we can see how many people use the site, which calculators they open and how long they stay. We do not store IP addresses and we do not use third-party advertising or analytics trackers.

Signing in: if you sign in to download a PDF, we store your email address, when you signed in, which sign-in method you used and which calculators you downloaded. If you sign in with Google, Microsoft or Yahoo, we receive only your email address from them.

Emails: we send you a sign-in code when you ask for one. We send other emails only if you ticked the box agreeing to receive them, and you can unsubscribe at any time.

Cookies and storage: we use a sign-in cookie to keep you signed in and browser storage to remember your calculator inputs and that you accepted the disclaimer.
