The service

Trove is a free, private catalogue for metal-detecting finds. Your catalogue is private by default, and you decide whether to share individual finds.

You keep all rights to the photos and information you add. You grant the operator the rights needed to store, process and display your content so the service can work for you, and the rights described in the next two sections. You confirm that you hold the necessary rights to everything you upload.

AI tools and local training

Trove uses AI tools to help identify finds. By using Trove you agree that the photos and identifications you add may be used to locally train and improve the AI tools used on this site.

In particular, our AI tries to detect maker's marks and fineness or purity marks on items that carry them. From these marks Trove keeps a collection of picture clippings in which only the actual mark is visible, together with the mark's identification and copies of the reference sources it is based on. The collection serves as reference material for future identifications. Clippings are cropped to the mark and carry no metadata, location or other details of your find or account.

No data is sent to any AI provider without your explicit approval. Each time you submit a request with one of our AI tools, you approve sending the data that request describes (for example the photo or fields you selected) to the AI provider, for that request only. The one exception is the shared mark collection: its clippings show only a mark and are site reference material, so they may be sent as comparison images when anyone runs a mark identification.

AI results are suggestions and may be wrong. Check every identification before you rely on it.

Public catalogue of maker's and fineness marks

We reserve the right to publish the mark clippings separately and publicly on our site. The purpose is a catalogue of maker's marks and fineness marks with real-world pictures of stamps and their variations.

For this purpose you grant the operator a non-exclusive, free-of-charge, worldwide, unlimited-in-time right to store, crop, edit, reproduce and publicly display these mark clippings. The right continues after you delete a find or your account. Published clippings are never shown with your name, your account, the find they come from or its location.

You can opt out of the mark collection at any time by contacting support at [email protected]. After you opt out, marks from your photos are no longer added to the collection, and on request the clippings already taken from your photos are removed from the collection and from the public catalogue.

Changes and applicable law

The operator may update these terms. Material changes are announced on the site before they take effect. The law of the Federal Republic of Germany applies.
