What you type into a calculator

Your dates, salary and other answers are worked out by your own browser, on your phone or computer. They aren’t sent to us, saved by us or shared with anyone.

If you share a result on WhatsApp or copy it, only you decide where it goes.

Cookies and tracking

This site doesn’t set cookies. It doesn’t use analytics, advertising trackers or social-media widgets.

Loading the pages

Like any website, the pages are delivered by a hosting provider, which handles the technical details of each request (such as your IP address) under its own privacy policy.

If you email us

If you report a mistake by email, we use your message only to check the report and, if you ask, to reply. Please don’t include personal documents.

Changes

If we ever add advertising or analytics, we’ll update this page before they go live, and say what they collect.
