The Index is three kinds of material, each under its own terms.

Curated data

Published under CC BY-SA 4.0. Credit it as "Mineral Index, Vol. 04".

Editorial text

Published under CC BY-SA 4.0.

Photographs

Licensed one by one. The terms sit in each image's caption — the Index does not license them as a set.

Want to go further — redistribute the dataset in bulk, or build it into another product? That needs a written agreement. Write to contact@mineralindex.org.

The Index is a scholarly reference, not professional advice. We source every value we can, but mineralogy keeps moving, and entries are revised.

Do not rely on the Index for safety decisions about hazardous material. Before you handle anything dangerous, consult the cited authority — IRSN, HSE, NIOSH, or its equivalent where you are.

We collect as little as the site can run on, and we process it in the European Union under the GDPR.

Server logs

Your IP address, browser, the page, and the time — kept 30 days, for security. Legal basis: legitimate interest.

Audience measurement (Umami)

Self-hosted and cookieless. It counts visits in aggregate, shares nothing with anyone, and never follows you across the web. Exempt from consent as audience measurement (CNIL); legal basis, legitimate interest. You can object — see your rights below.

Correspondence

Anything you send to contact@mineralindex.org, kept for as long as the matter is open.

You can ask to see, correct, delete, move, or object to the data we hold on you — write to contact@mineralindex.org. You can also complain to the CNIL at cnil.fr.

The Index sets no cookies. Umami is cookieless, and we run no advertising and no third-party trackers.

Your theme choice and recent searches stay in your browser, on your device, and never reach us.

One address for everything — corrections, licensing, data requests, or a simple hello: contact@mineralindex.org.
