Privacy

We don't use cookies, advertising trackers or third-party analytics. The calculator runs entirely in your browser, and nothing you type into it is sent to us.

We keep a simple count of page views per day: the page path and the date only. We store no IP addresses and no personal information. Our host, Cloudflare, processes requests to deliver the site, as any web host does.

If you email us, we use your message only to reply and to fix the site. This notice is in line with POPIA.
