Choosing your alerts

You can receive all types of alert or only some. Alerts can be limited to certain countries or categories of objects, so that you receive only the messages useful to your activity.

A gallery owner specializing in archaeology will, for example, choose theft and suspect-work alerts for that category, without receiving the others.

Frequency and content of messages

Alerts are sent as they occur, after validation. A subscriber receives on average a few messages a week, depending on their filters. Each message reproduces the full record and a link to the alert page.

The message is written in the language chosen at registration: French, English or Spanish.

Confirmation and data protection

Registration is confirmed by a message containing a validation link. As long as the link has not been clicked, no alert is sent. This step prevents registrations made without a third party's knowledge.

The e-mail address is used only for sending alerts. It is neither transferred nor used for other purposes, in accordance with the Organization's privacy policy.
