Privacy

Every calculator on this site runs entirely in your browser. The values you type — salary, rent, loan figures, dates of birth, dimensions, rates — are never sent to us and are never stored. There is no account and no sign-up.

We do not sell data. We measure how the site is used so we can improve it: page views, plus aggregate interaction events — that a calculator was opened and produced a result, that a share button was clicked, or that a source link was opened. These events never carry the values you type and are not used to identify you. We do not set advertising cookies.

The government-exam age-limit checker also processes your date of birth in the browser only. Nothing you enter on any page leaves your device.
