What this site collects
This site doesn’t ask for your name or email, doesn’t use accounts, and doesn’t sell personal information.
- Calculator inputs are saved only in your own browser (localStorage) so they’re still there next time. They’re never sent to us. Use “Start over” or clear your browser data to remove them.
- Hosting: the site is hosted on Cloudflare, which processes standard technical data such as IP addresses to deliver pages and protect against attacks. See Cloudflare’s privacy policy.
