Privacy

Short version: there is very little to collect, and we collect even less.

What we do not have

No accounts, no sign-ups, no newsletters, no comment sections, no contact forms. Nothing you type into a calculator leaves your browser - the math runs on your device.

Analytics

The site uses Cloudflare Web Analytics, which is cookieless and does not identify individual visitors. It counts page views in aggregate so we can tell which pages are useful. That is the whole list.

What we never do

We do not sell, rent or share personal data, because we do not have any. There are no advertising trackers on this site.
