Privacy and cookies
Short version: we don't collect personal data ourselves. Our host processes IP addresses to deliver pages (see Hosting below).
What we collect
We don't collect personal data ourselves. This site has no forms, no accounts, no email sign-up, no comments and no analytics or advertising trackers. Our host processes IP addresses to deliver pages; see Hosting below.
Cookies
We set no cookies and use no similar technologies such as local storage.
The calculators
Our calculators run entirely in your browser. The numbers you type are not sent to us or anyone else, and they're cleared when you leave or reload the page.
Hosting
Like any website, the server that delivers these pages processes your IP address and basic request details in order to send them to you. We don't use that information to identify or track you.
Links to other sites
We link to manufacturers and official sources. Their own privacy policies apply once you leave this site.
Changes
If we ever add a form or analytics, we'll update this notice first, including who is responsible for your data.
