What we collect

The calculators run entirely in your browser. Nothing you type into them is sent to us or stored.

Like most websites, our hosting provider keeps standard server logs, such as IP address, browser type and the pages requested, to keep the site secure and working.

Advertising and cookies

This site may show ads served by Google AdSense. Google and its partners use cookies to serve ads based on your visits to this and other websites. You can turn off personalized advertising in Google's Ads Settings, and read how Google uses data at policies.google.com/technologies/ads.

Where the law requires it, for example in the European Economic Area and the United Kingdom, you will be asked for consent before advertising cookies are used.

Analytics

This site uses Google Analytics 4 to count visits and see which calculators get used. It sets cookies in your browser and sends Google information about your visit, such as the pages you opened, roughly where in the world you are, and the type of device and browser you used. Google Analytics 4 does not log or store your full IP address.

We use this only in aggregate, to decide which calculators to build next. We do not try to identify individual visitors, and nothing you type into a calculator is included: those run entirely in your browser and the numbers never leave it.

You can opt out across all sites with Google's Analytics opt-out browser add-on, or by blocking cookies for this site. How Google handles the data is described at policies.google.com/privacy.
