xAI Grok

Data-handling profile

Trains on input

Yes, on the consumer tier (enterprise tier excluded)

Retention

By default xAI may use conversations to train future Grok models; opt-out available in settings but only affects future data (already-collected data cannot be retroactively removed from trained models). Deleted conversations/accounts are queued for deletion, generally removed within 30 days unless retained for legal/safety reasons. Private Chat mode excludes conversations from training and history. No published fixed retention window for active-account conversation history.

EU AI Act

Default training-on-input posture plus tight integration with X (Twitter) social data raises EU AI Act transparency and lawful-basis-for-training scrutiny; opt-out is not retroactive.
