Your calculator answers
The CRS calculator runs entirely in your browser. Your answers are not sent to us or stored on our servers. To save you retyping, your browser keeps your last answers in its local storage on your device. You can clear them at any time with the calculator's "Start over" button or by clearing your browser's site data.
If you use "Copy link to my answers", your answers are written into the link itself. Anyone you send that link to can see them.
Hosting
This site is hosted on Cloudflare Pages. Like any web host, Cloudflare processes technical information such as your IP address to deliver the site and protect it from abuse.
Fonts
The site loads fonts from Google Fonts, so your browser connects to Google's servers, which receive your IP address.
If you email us, we use your email address and message only to reply to you.
Changes
If we add analytics or advertising, we will update this page before doing so.
