Policy Details & Nuances

Default Model Training
Yes

Both your direct chats with Grok and your public posts on X are used by default to train Grok models. API platform accounts are excluded from training and covered by separate terms.

Opt-Out Mechanism
Yes

On the X platform, go to Settings and Privacy > Privacy and safety > Grok, and toggle off the training option. On the x.ai portal, go to Data Controls and deselect 'Improve the model'.

Data Retention & Deletion

Retention Period

Conversations and posts are retained as long as necessary for model training and service delivery. Private Chat conversations are deleted within 30 days unless legal or safety reasons require longer retention.

Deletion on Request

Yes

Grok chat history can be cleared in the UI. Public posts on X that have already been ingested into training sets cannot be easily purged or recalled. Account deletion also triggers deletion within 30 days.

Third-Party Data Sharing

Shared with X Corp affiliates and service providers under vendor agreements.

Human Review of Chats
Yes

Logs may undergo human review for safety filtering, alignment verification, and reinforcement learning purposes.

Context & Variations

Enterprise vs. Consumer

Developer API platform services have separate terms where prompt inputs are not used for training and are subject to standard enterprise security policies.
