To stop X from using your Grok conversations for model training and fine-tuning, turn off the training option in Settings and privacy → Privacy & Safety → Data sharing and personalization → Grok & Third-party Collaborators. X says you can continue using Grok after opting out. The setting’s labels may change, so look for the Grok Data Sharing controls if your account shows a different layout.
Turn off Grok training in X settings
- Sign in to the X account whose data you want to control.
- Open Settings and privacy → Privacy & Safety.
- Go to Data sharing and personalization, then open Grok & Third-party Collaborators.
- Under Data Sharing, turn off “Allow your public data as well as your interactions, inputs, and results with Grok and xAI to be used for training and fine-tuning.” Check that the control is deselected after changing it. X’s About Grok help page describes the control and says opting out does not prevent you from using Grok.
Find the control in the mobile app
On iOS or Android, X’s general route to personalization and data controls is: tap your profile photo at the upper left, then Settings and privacy → Privacy and safety → Personalization and data. From there, follow the Grok and Data Sharing labels to the training option. X does not document a separate, more specific mobile subpath. On desktop, use X’s Personalization and data settings.
When signed in, these settings apply to the account on devices where that account is logged in. When logged out, settings affect only the current browser while you remain logged out, according to X’s personalization and data settings guidance.

X says it may share public X data and your Grok interactions, inputs, and results with xAI to train and fine-tune Grok and other generative AI models. The described data includes voice interactions and voice-input transcriptions or translations. Public data includes posts and associated metadata, public Spaces, and public profiles. X says opting out excludes your personal data about Grok interactions, inputs, and results from that model creation and fine-tuning use, while allowing you to keep using Grok.

- Online video installation instruction: Easiest Installation - removing dust and aligning it properly before actual installation,enjoy your screen as if it wasn't there.
- It does not disable every kind of model learning. X says normal use of deployed Grok-powered features on X, such as recommendations, can still teach a deployed model. The training opt-out does not prevent this, according to X’s explanation of Grok controls.
- Conversation feedback has a stated exception. X says feedback on a conversation, such as a thumbs-up or thumbs-down, may still let X and xAI use that conversation and related data for training and fine-tuning even after you opt out. X advises against submitting feedback if you do not want that use. See About Grok.
- Personalization is a different setting. The separate Grok Personalization control governs whether personal data is used to personalize your Grok experience; it is not the training opt-out.
Choose separate controls for separate privacy goals
Stop future training use
Use the Data Sharing training and fine-tuning control described above. This is the setting for opting out of the specified use of public data and Grok interactions, inputs, and results.
Remove conversation history
To delete existing history, X documents Delete Conversation History under Privacy & Safety → Data sharing and personalization → Grok. X says deleted conversations are removed from its systems within 30 days, unless retention is needed for security or legal reasons. Deleting history and opting out of future training are distinct actions. Details are in X’s About Grok help page.

Prevent public posts from being used
X says making your account private with Protect your posts prevents posts from being used to train underlying Grok/xAI models or surfaced in responses to user queries. That addresses posts; it is not a substitute for the Data Sharing opt-out, which also covers the described Grok interactions, inputs, and results. X discusses post-data processing and controls in its Additional information about data processing.
