Privacy Policy
The short version
- Calculators run entirely in your browser. Numbers you enter are never sent to us.
- No accounts, no ad-tracking cookies, and we don't sell personal data.
What our host may log
Like any website, our hosting provider may process standard request data (IP address, browser type, pages requested) to deliver the site and protect it from abuse. If we add privacy-friendly, cookieless analytics to count visits, this page will name the provider before it's turned on.
Sponsors and outbound links
Sponsor links are ordinary links marked rel="sponsored". We don't share visitor data with sponsors. Once you leave this site, the other site's privacy policy applies.
If you email us, we use your message only to reply and don't add you to any list without your explicit opt-in.
