To opt out of Grok (xAI) in 2026: (1) go to X → Settings → Privacy and safety → Data sharing and personalization and uncheck “Allow your posts and interactions with Grok to be used for training,” (2) delete your Grok conversation history from grok.com, (3) submit a deletion request at x.ai/privacy-portal or email privacy@x.ai, and (4) delete your Grok account entirely if you no longer use it. Once your data has been used in a training run, it cannot be pulled back out — so opt out now.
What Grok Collects About You
Grok is xAI's large language model, deeply integrated with the X platform (formerly Twitter). It has access to far more data than most AI assistants:
- Your public X posts, replies, likes, and bookmarks — used for both real-time answers and model training by default
- Every conversation you have with Grok on grok.com, in the X app, or via the mobile Grok app
- Uploaded files and images you share with Grok during a conversation
- Account metadata — email, phone number, subscription tier, IP address, device information
- Interaction telemetry — what you clicked, how long you spent, which responses you regenerated
The Opt-Out Is Not Retroactive
xAI's own privacy policy states that once your data has been included in a training run, it cannot be removed from the model. Opting out only stops future conversations and posts from being used. That's why the timing of this matters — every day you wait is another day of your posts and prompts feeding xAI's next model.
Why Opt Out of Grok
Unlike ChatGPT or Claude, Grok is trained on live X data by default — your public posts, replies, and interactions with the assistant. That has real consequences:
- Model memorization. Large language models can regurgitate rare or unique text from training data. Anything distinctive you've posted publicly can end up quoted back by Grok to another user.
- Deanonymization. Combining a public username with private conversations creates a rich profile that xAI can retain indefinitely.
- Cross-service exposure. xAI is part of the broader X Corp / Musk portfolio; data sharing across corporate affiliates is permitted in the privacy policy.
- Government requests. Grok chat logs are business records subject to subpoena or National Security Letters just like email — and xAI has no zero-knowledge architecture protecting them.
Step 1: Turn Off Grok Training on Your X Posts
This is the single most important toggle because it stops X from feeding your public posts and Grok interactions into training runs.
- Sign in at x.com on a desktop browser (the mobile app hides some options)
- Click More in the left sidebar
- Click Settings and privacy → Privacy and safety
- Scroll to Data sharing and personalization → Grok
- Uncheck “Allow your posts as well as your interactions, inputs, and results with Grok to be used for training and fine-tuning”
- Save
Repeat on every X account you own, including private/locked accounts — the setting is per-account, not per-user.
Step 2: Delete Your Grok Conversation History
Turning off training doesn't erase what's already in your history — and xAI retains conversation logs even after training opt-out. Clear them:
- Go to grok.com (or open the Grok tab in the X app)
- Open Settings → Data controls
- Click Delete all conversations and confirm
- Also toggle Improve the model for everyone to off if it is present — this is a second, separate training toggle inside Grok itself
Step 3: Submit a Formal Data Deletion Request
Steps 1 and 2 handle the toggles. Step 3 forces xAI to delete the underlying records they still hold about you.
- Open x.ai/privacy-portal
- Choose Delete my personal information
- Verify your email and complete the request
Or email privacy@x.ai with this template:
Deletion Request Template
Subject: Data deletion request under CCPA / GDPR
To Whom It May Concern,
Under the California Consumer Privacy Act (or the GDPR if I'm an EU/UK resident), I am requesting that xAI permanently delete all personal information associated with my account, including but not limited to my Grok conversation history, uploaded files, prompts, and any derived embeddings or fine-tuning artifacts. Please also opt me out of the sale or sharing of my personal information going forward.
Registered email: [your email]
X username: @[your handle]
Please confirm completion within 45 days as required by law.

Step 4: Delete Your Grok Account Entirely
If you don't plan to use Grok, close the account so no new data accumulates.
- At grok.com go to Settings → Account → Delete Grok account
- Enter your email to confirm
- You'll receive an email confirming your account is marked for deletion and will be permanently removed within 30 days
Note: this deletes your Grok account but not your X account. To delete X too, go to X → Settings → Your account → Deactivate.
Step 5: Prevent Re-Enrollment
xAI Has Flipped Users Back In Before
In 2024 X quietly enabled Grok training by default for existing accounts. Feature launches can silently re-enable opt-outs, so re-check the toggle in Step 1 every 60–90 days, especially after any big X or Grok product announcement.
What xAI's Opt-Out Does Not Cover
- Data already used in past training runs. That's baked into the model weights forever.
- Public X posts already indexed by other AI companies. OpenAI, Anthropic, Google, and Perplexity have also scraped X historically. Opting out of Grok doesn't opt you out of them — see our AI training data removal guide.
- Data brokers holding your public X profile. Sites like Spokeo, BeenVerified, and Whitepages independently scrape public social profiles. Removing yourself from those requires a separate data-broker opt-out sweep.
Grok Opt-Out on Mobile
The mobile X app hides some privacy controls, but the essential toggle is reachable:
- Open the X app → profile icon → Settings and privacy
- Tap Privacy and safety → Grok
- Turn off Data sharing
For the full workflow (deletion request, account close), use a desktop browser.
Frequently Asked Questions
Can I stop Grok from training on my X posts entirely?
Yes for future training runs. Go to X Settings → Privacy and safety → Data sharing and personalization → Grok, then uncheck the training checkbox. Past posts already included in existing model versions cannot be pulled back out — that's why the sooner you flip the toggle, the less exposure you have.
Does deleting my Grok conversations delete them from the model?
No. Deleting a chat removes it from your visible history and from xAI's active retention, but if the conversation was already included in a fine-tuning run it remains embedded in the model weights. Only future conversations are guaranteed to be untouched once you've opted out.
Is Grok safe to use with sensitive information?
No. Grok logs everything you send by default, may use it for training, and has no zero-knowledge architecture. Never paste medical records, passwords, financial account numbers, employer confidential information, or anything you wouldn't want a stranger to read into any Grok chat.
How long does xAI take to process a deletion request?
CCPA requires a response within 45 days (extendable to 90 with notice). GDPR requires 30 days. xAI's public policy commits to “without undue delay.” File the request at x.ai/privacy-portal and keep the confirmation email as proof.
What about Grok in third-party apps that use xAI's API?
Third-party apps built on the xAI API have their own privacy policies — xAI's opt-out doesn't automatically cover them. Check each app's data-handling terms and delete data with that vendor separately.
Do I have to opt out of Grok for every AI service too?
Yes, each major AI vendor has its own opt-out process. See our guides on removing yourself from ChatGPT and removing yourself from AI training data. Or let PrivacyOn monitor and remove your personal information from 100+ broker sites so there's less about you to scrape in the first place.
Cut Off Grok's Data Supply at the Source
Opting out of Grok is a critical step, but the underlying problem is that data brokers keep leaking your name, address, phone, and relatives onto the public web where every AI scraper picks them up. PrivacyOn removes your personal information from 100+ data brokers and monitors 24/7 to keep it removed, starting at $8.33/month with dark web monitoring included. Family plans cover up to 5 people.
