Privacy Policy

Calculator inputs are processed entirely in your browser and are not sent to or stored on our servers.

Analytics

We use GoatCounter, a privacy-friendly analytics service, to count page views. According to the GoatCounter documentation, it stores aggregate data and keeps only computed values, not the IP address or User-Agent they were derived from. See GoatCounter's GDPR notes.

Advertising and affiliate links

If we add advertising or affiliate links in future, this policy will be updated first to describe the cookies and partners involved.

Hosting

The site is hosted on Cloudflare Pages, which may process standard server logs (such as IP address) to deliver the site. The old plugmath.netlify.app address only redirects here; Netlify may log those redirect requests.

Changes

We will post updates on this page.
