Your calculations stay on your device

Every calculator runs entirely in your browser. The numbers you enter are used to render the result on screen and are never transmitted to a server, stored, or logged by us.

Because nothing is sent anywhere, there is no calculation history for us to keep, share, or lose.

Accounts and cookies

You do not need an account to use anything on this site, and we do not ask for your name, email address, or any other personal detail in order to show you a result.

The site does not set advertising or tracking cookies. Your browser may store ordinary technical data (such as cached files) to make pages load faster.

Third parties and changes

Pages are served as static files. If analytics or advertising is introduced in future, this page will be updated to say exactly what is collected before that change goes live.
