Privacy policy

Last updated: 2026-09-26.

We don't require accounts and don't collect personal data through forms. The calculator runs entirely in your browser; your inputs live only in the page URL you choose to share.

Our hosting provider may log standard technical data (IP address, user agent) for security. If we add privacy-friendly analytics or affiliate tracking, affiliate partners may set cookies after you click a /go/ link; those are governed by the partner's policy. This page will be updated before any such change.
