Example Snooper Settings Page

Snooper is a feature Mojang is using to collect data on users, either by the Client or by the Server. This feature was removed in 1.13 globally because of the European Union's General Data Protection Regulations.[1] However, it was re-added in Java Edition 1.18 snapshot 21w38a to "find where the biggest problems in the game were".[citation needed]
