Metrics

Crush records pseudonymous usage metrics (tied to a device-specific hash), which maintainers rely on to inform development and support priorities. The metrics include solely usage metadata; prompts and responses are NEVER collected.

Details on exactly what's collected are in the source code (here and here).

You can opt out of metrics collection at any time by setting the environment variable by setting the following in your environment:

export CRUSH_DISABLE_METRICS=1

Crush also respects the DO_NOT_TRACK convention which can be enabled via export DO_NOT_TRACK=1.
