Telemetry Data Collection (formerly called Snooper) is a feature in Minecraft: Java Edition that allows Mojang Studios to collect telemetry data on the player, either by the client or by the server. On the telemetry data collection screen, the player can view the collected data and choose between sending a required "minimal" amount of data or an extended "all". It also includes a link to the stored data files.
This feature was removed globally in 18w21a because of the European Union's General Data Protection Regulations (GDPR).[1] It was re-added as always-on in 21w38a to "improve players' experience",[2] and since then it is no longer possible to disable telemetry data collection completely without client modifications. It is still questioned if the current system is GDPR compliant or not.
