Privacy
Your inputs stay in your browser
Everything you type into a calculator is worked out on your device. Nothing is sent to us. If you choose, your inputs are kept in your browser's local storage so other pages can pre-fill them; the Forget my inputs button on each calculator removes them. We never see them.
Share links
A share link carries your inputs in the part of the address after the # sign. Browsers do not send that part to any server, and the site strips it before anything is counted. Anyone you give the link to can see the inputs in it, so share it as you would any note about your pay.
What is counted
At the moment nothing is counted at all: no analytics script runs on this site. When first-party counting starts it will record only which pages are viewed, which page a visit came from, the rough size of the screen and which calculator inputs were used by name, never their values, in aggregate, with no cookie and no identifier, and this page will say so.
Opting out
Your browser's Do Not Track or Global Privacy Control setting is honoured. You can also switch counting off for this browser here:
Advertising
No advertising cookies are set today. When display advertising starts, a Google-certified consent platform will ask before any advertising cookie is set, with rejecting as easy as accepting, and this page will list which partners can set cookies and how to change your choice. Ads will sit in labelled spaces outside every result, and will never receive a calculator input.
