Privacy
Calculations run in your browser. Nothing you enter is collected, sent to a server, or shared.
This site has no ads, no tracking and no external scripts or fonts. Your measurement and currency choices are stored only in localStorage on your own device so the site remembers them next time. You can clear them at any time in your browser settings.
If this policy changes, the updated version will be published on this page.
If analytics is ever activated, this page, the homepage and the FAQ will be updated in the same release, before activation, to name the service, what it collects, and how to opt out.
One technical note: an analytics configuration file ships with this site, but it stays inactive while its measurement IDs are placeholders, so it loads no analytics or tracking service and collects nothing.
