How do I stop Grok from training on my data?
On X, go to Settings and privacy > Privacy and safety > Grok & third-party collaborators, and uncheck the box that allows your posts and interactions to be used for training. In the Grok app or grok.com, open Settings > Data controls and turn off model training. Opting out only affects future data, not what was already collected.
Why — the first-principles explanation
AI models like Grok get smarter by learning from examples. Your chats, feedback, and (on X) your public posts are useful training material, so by default xAI's systems are set to opt-in: your data is used unless you turn it off. That default exists because more data generally means a better model, and the company benefits from it.
The opt-out is a switch, not an eraser. When you flip it, you tell xAI to stop feeding your future activity into training. But data already collected and already baked into a trained model can't be pulled back out, so the timing matters: the sooner you switch it off, the more of your activity stays out.
There's also a subtle trap. Even after opting out of general training, if you click 'Helpful' or 'Not Helpful' on a Grok answer, you're manually volunteering that specific exchange for improvement (a process called RLHF). And note the two settings are separate: turning it off inside the Grok app doesn't automatically change your X posts setting, and vice versa. To fully limit it, adjust both, and remember X says data from private accounts is excluded from training entirely.
An example that makes it click
Imagine a chef who tastes every dish customers send back to improve the menu. By default, your plate goes to the kitchen for tasting. The opt-out is a little card on your table that says 'don't taste mine.'
But two things are true. First, the card only works going forward, dishes already tasted last week are already part of the recipe. Second, if you personally walk a bite over and say 'here, try this,' by rating an answer thumbs-up or thumbs-down, you've handed it over anyway. So set the card, and stop hand-delivering samples.
How to do it
- On X (web or app): open More > Settings and privacy > Privacy and safety.
- Choose 'Grok & third-party collaborators' (may be labeled 'Data sharing').
- Uncheck the box that allows your posts and interactions to be used for training.
- In the Grok app or grok.com: open Settings > Data controls (or Privacy).
- Turn off the option to use your conversations to improve or train the model.
- Avoid clicking 'Helpful'/'Not Helpful' on answers, since that opts that chat in.
- Optional: set your X account to private, which excludes it from AI training.
Key facts
- Training on your data is opt-in by default; you must turn it off manually.
- On X: Settings and privacy > Privacy and safety > Grok & third-party collaborators, then uncheck the box.
- In Grok's own app/site, a separate Data controls setting governs chat training.
- Opting out only affects future data; already-collected data is not removed.
- Rating an answer 'Helpful' or 'Not Helpful' opts that specific interaction into training (RLHF).
- X states data from private accounts is excluded from all AI training.

How do you stop Grok from training on your data? By default it's opt-in, so you have to turn it off yourself, in two places. First, on X: go to Settings and privacy, then Privacy and safety, then Grok and third-party collaborators, and uncheck the box that lets your posts and interactions be used for training. Second, in the Grok app or on grok.com: open Settings, find Data controls, and switch off using your conversations to improve the model. Two important catches. One, this only stops future data. Anything already collected and baked into the model can't be pulled back, so do it sooner rather than later. Two, even after opting out, clicking Helpful or Not Helpful on an answer hands that specific chat over anyway, so avoid rating replies if you want maximum privacy. And if you set your X account to private, X says that data is excluded from training entirely.
What authoritative sources say
People also ask
Does opting out delete my past data?
No. It only stops future use. Data already collected or already inside a trained model cannot be removed by the toggle.
Do I have to change settings in two places?
Yes for full coverage: the X posts setting and the Grok app's data-controls setting are separate switches.
Does rating answers affect this?
Yes. Clicking 'Helpful' or 'Not Helpful' opts that specific exchange into training, even if you turned off general training.
Are private X accounts used for training?
No. X states that data from private accounts is excluded from all AI training and remix tools.
