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.
- Data region
- US
- Certifications

- DPA available

- Breach 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.
