Privacy policy

Short version: the calculators run entirely in your browser. Nothing you type is sent to us or stored. We use no tracking cookies, no advertising tags and no analytics scripts.

What we collect

Nothing that identifies you. This is a static website: there are no accounts, forms that submit data, or comment boxes.

Cookies and local storage

This site sets no cookies and does not use local storage.

Server logs

The site is served by a hosting/CDN provider (Cloudflare Pages), which may process standard technical request data such as IP address and browser type to deliver pages and protect against abuse, under its own privacy policy. We do not use that data to profile visitors.

Links to other sites

Template links go to Payhip, which handles checkout and delivery and has its own privacy policy. Payhip's pages may use cookies; that only happens if you click through.

Changes

If this policy changes (for example, if we add cookieless, aggregate visitor counts), we will update this page first. Last updated 2026-11-15.
