Privacy Policy

Effective 21 September 2026. This static site does not run user accounts, newsletters, or advertising pixels.

What we collect

We do not ask you for a name, email, or payment. The host (Cloudflare Pages) may process standard server logs: IP address, user-agent, URL, timestamp. Those logs are used to operate and secure the site. We do not sell them.

Cookies

This site does not set first-party analytics or advertising cookies. Cloudflare may set technically necessary cookies for security (for example bot management). The yield estimator runs entirely in your browser after fetching /data/yields.json.

Third parties

Fonts may load from Google Fonts. If you block that request, the site still works with system fonts. Outbound links go to publisher sites (MDPI, ACS, etc.) under their own policies.

Your rights

Because we do not keep an identified user database, there is typically no profile to access or delete. For log-related questions, contact the operator via the hosting account listed in the Cloudflare project.

Retention

CDN logs follow the host’s default retention. We do not run a separate customer CRM for this handbook.
