What the simulator does with your numbers
The calculation runs in your browser. The numbers you enter are never sent to us. They are kept in the page address so you can share a result, which means anyone you send a link to can see those numbers, and your browser history keeps them too.
What we collect
No accounts, no cookies and nothing in your browser's local storage. The page's scripts, fonts and images all come from this site, apart from the visit counter's script, below.
Counting visits
We use Cloudflare Web Analytics to count visits. It sets no cookies and doesn't use your browser's local storage. For each page view it records the page address, the page you came from, your browser and device type, your country (worked out from your IP address, which isn't stored) and how long the page took to load. Cloudflare processes this on our behalf. It isn't used for advertising and doesn't track you across other sites.
Hosting logs
The site is hosted on Cloudflare Pages. Like any web host, Cloudflare handles your IP address and browser details to serve and protect the site, and may keep short-lived logs. If you share a link, the address including your numbers can be seen by whoever receives it, and by the host when the page is loaded. Cloudflare's own privacy policy covers what it does.
Advertising
There are no ads at the moment. If that changes, this page will be updated first, to name the ad network and say what it receives.
