Privacy

RationMath has no accounts, no sign-ups and no advertising trackers. The calculator runs entirely in your browser; nothing you type is sent anywhere.

We use Cloudflare Web Analytics to count page views. It doesn't use cookies, doesn't track you across sites and doesn't collect personal information. Our hosting provider, Cloudflare, processes standard request data (such as IP addresses) to serve and protect the site.

RationMath itself sets no cookies. Some links to Amazon include our Amazon Associates tag. If you click one, Amazon may set cookies in your browser so it can credit a purchase to us; that happens on Amazon's site, under Amazon's privacy notice. Brand stores you visit from here have their own privacy policies.
