How to Disable Grok's Data Usage on X

You probably didn’t sign up to be an AI training dataset.

But if you use X (formerly Twitter), that’s exactly what’s been happening — quietly, in the background, by default.

X automatically opted every user in to share their posts, replies, and Grok interactions with xAI for model training. No notification. No consent pop-up. Just a pre-checked box buried in your settings.

And it gets more widespread than you’d think. A 2024 Pew Research Center study found that 81% of consumers believe companies will use AI-collected data in ways they never agreed to. Another KPMG study found 63% of people are genuinely worried about AI compromising their personal privacy.

If you’re one of those people — this article is your 2-minute fix.

Here’s exactly how to turn it off, on both desktop and mobile, right now.

How to Disable Grok’s Data Usage on X

There are two ways to do this — desktop and mobile. Both take less than two minutes.

On Desktop (Recommended)

Desktop is the fastest and most reliable way to change this setting. Here’s the step-by-step:

Step 1: Go to x.com and log into your account.

Step 2: Click on “More” from the left sidebar menu.

Step 3: Select “Settings and privacy.”

Step 4: Click on “Privacy and safety.”

Step 5: Scroll down to the “Data sharing and personalization” section.

Step 6: Click on “Grok” (also sometimes labeled “Grok & Third-party Collaborators”).

Step 7: Uncheck the box that reads: “Allow your posts as well as your interactions, inputs, and results with Grok to be used for training and fine-tuning.”

Step 8 (Optional but recommended): Click “Delete conversation history” to remove any past data you’ve already shared with Grok.

That’s it. You’re out. X can no longer use your content to train its AI models.

On Mobile (iPhone & Android)

The mobile path is slightly different, but still straightforward:

Step 1: Open the X app on your phone.

Step 2: Tap on your profile icon (top left corner).

Step 3: Tap “Settings and Support” → then “Settings and privacy.”

Step 4: Tap “Privacy and Safety.”

Step 5: Scroll to “Data sharing and personalization.”

Step 6: Tap “Grok.”

Step 7: Toggle off the setting that says: “Allow your posts as well as your interactions, inputs, and results with Grok to be used for training and fine-tuning.”

Done. Settings are saved automatically on mobile — no need to hit a save button.

Quick note: Some users have reported the mobile interface lags behind the desktop version when X rolls out updates. If you don’t see the Grok option right away, use the desktop version to be safe.

What Happens After You Opt Out?

Here’s what changes (and what doesn’t):

What stops:

• X can no longer use your posts or interactions to train Grok.
• Your future conversations with Grok won’t be used for model fine-tuning.

What doesn’t change:

• X still holds your personal data on its servers.
• Opting out of AI training doesn’t equal data deletion.
• If you want your data fully removed, you’d need to submit a formal data deletion request directly to X.

One more thing worth knowing: According to data from Stanford’s 2025 AI Index Report, AI-related privacy incidents jumped 56% in a single year — with 233 documented cases in 2024 alone. Opting out is a small action, but it matters.

Conclusion

X turned on Grok data sharing for everyone — by default, without asking.

The fix takes less than two minutes. Go to Settings → Privacy and Safety → Data Sharing and Personalization → Grok → uncheck the box. Done.

It’s a small action, but in a world where 57% of consumers globally feel AI poses a significant threat to their privacy (IAPP, 2024), taking control of your own data is worth the two minutes it takes.

And now you don’t need to Google this again.
