Privacy

Your figures stay in your browser

The calculator runs entirely on your own device. The incomes you type are never sent to us, never stored on a server, and never logged. Close the tab and they are gone. There is no account, no sign-in and no form submission.

What is stored on your device

One item in your browser's local storage, recording whether you chose the light or dark theme. It is not a cookie, it is not sent anywhere, and clearing your browser data removes it.

Advertising

This site does not show ads yet. It has applied to Google AdSense, and when ads are switched on, Google and its partners may use cookies or similar technologies to serve ads based on your prior visits to this and other websites. This section is here in advance so the policy is accurate on the day that changes.

You can review and change what Google collects at My Ad Center, and read how Google uses data from sites that use its services at Google's partner-sites policy. Visitors in the EEA and the UK are asked for consent before any advertising cookie is set.

Your income figures are not shared with advertisers, and neither is the number of children you enter. They never leave your browser, so there is nothing to share.

Server logs

The site is served as static files by a hosting provider, which keeps ordinary request logs (IP address, user agent, page requested) for operational and security purposes. We do not use them to build a profile of you.
