+GrayJay contains telemetry. On each start, it will send your OS version, device model and app version with a randomly generated unique identifier. FUTO says that it is used to " understand our user base, which devices are most commonly used, and ensures that we optimize our app for those devices" and that the random id helps identifying unique app launches.
