Privacy

This site does not use cookies, does not ask for your name or email, and does not track you across other websites.

Analytics

We use Plausible Analytics to count page views and a few anonymous events, such as printing a page or using the calculator. Plausible does not use cookies and does not collect personal data. Visit counts are aggregated and cannot identify you.

Calculator and lookup

The compost calculator and the A–Z filter run entirely in your browser. Nothing you enter is sent anywhere or stored.

Hosting

The site is served by Cloudflare, which processes standard technical data such as IP addresses to deliver pages and protect against abuse.
