Grok lets signed-in users turn off training on their content but claims an irrevocable perpetual sublicensable licence over everything submitted, and users who access the service without logging in grant full rights to their data with no choice at all.

What Grok's privacy policy and terms of service say about your data

Perpetual content licence

Submitting input grants xAI an irrevocable, perpetual, transferable, sublicensable, royalty-free, worldwide right to use, modify, publish and distribute that content for any purpose.

Logged-out users have no opt-out

The training opt-out only exists when signed in; accessing the service without logging in grants xAI full rights to use the data for product development and model training.

Thirty-day deletion, qualified

Deleted conversations and closed accounts are cleared within 30 days unless the data is kept longer for legal, compliance, or safety purposes, and the general retention rule is an ongoing legitimate business need with no stated period.

Security described only as reasonable

The policy promises commercially reasonable technical, administrative, and organizational measures and names no specific control, certification, or breach-notification timeframe.

What the policy is silent or vague on

Not stated: your ownership of generated outputs
Not stated: data portability
Not stated: shorter retention for AI conversation logs
Not stated: a sub-processor list or data processing agreement
