The telemetry data collection screen.

Telemetry Data Collection (formerly called Snooper) is a feature that allows Mojang Studios to collect telemetry data on the player, from either the client or the Minecraft: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).<ref>Template:Bug "This is Working as Intended due to GDPR."</ref> It was re-added in 21w38a to "improve players' experience",<ref>Template:Snap</ref> and since then it is no longer possible to disable telemetry data collection completely without client Minecraft:modifications.
