Who runs this site

Green materials radar is built by Zayd Ahmad Shahizam in Utrecht, the Netherlands. For anything about your data, email [email protected].

Analytics, only if you agree

If you accept, PostHog measures which pages are visited, where people click and how far they scroll, so the site can be improved. That includes heatmaps. Data is stored in PostHog's EU cloud. There are no session recordings, and nothing is sold or shared for advertising.

If you decline, no analytics cookies or storage are used. Your browser's Do Not Track and Global Privacy Control settings are respected.

Comments

When you leave a comment, the site stores the comment, the page and the text you selected, and your name and email if you choose to give them. A short-lived, hashed session id lets you see your own comments. Comments are private to Zayd unless he makes a thread public. Your IP address is used only briefly to limit spam, and is not stored with the comment.

Your choices

You can ask for your comments to be removed, or for a copy of what is held about you, at any time. To change your analytics choice, clear this site's cookies and storage, and the question will appear again.
