What you enter
The numbers you enter into a calculator are sent to our server so it can compute the result, and they appear in the address of the page so you can share it. We do not store them in a database and we do not link them to you.
Accounts and cookies
There are no accounts. At the moment the site does not set tracking cookies and does not show advertising. If that changes, this page will be updated first and, where the law requires it, you will be asked for consent.
Server logs
Like most web servers, ours may keep short-lived technical logs (IP address, requested address, time) for security and troubleshooting.
