LeaGrok privacy settings: what to change on X and in the app
Grok on X and Grok in its own app have different privacy menus. Find the right controls, and check what changes when a bot can act for you.
You open Grok for a quick question. A few weeks later, it knows rather more about your life than you expected. Perhaps you have shared a personal problem, a screenshot or a private conversation. The first useful question is simple: where are you using Grok? The answer changes which settings you need.
Using Grok on X? Start here
In X settings, open Privacy & Safety, then Data sharing and personalization. Select Grok & Third-party Collaborators. Under Data Sharing, turn off the option allowing your public data and Grok interactions to be used for training and fine-tuning if that is your preference.
Personalization has a separate control in that area. Turning off training does not automatically turn off personalization. Check both rather than assuming one switch covers everything.
Using grok.com or the Grok mobile app?
On grok.com, open Settings > Data and review Improve the Model. In the mobile app, the documented path is Settings > Data Controls. Switch model improvement off if you do not want new conversations used for training.
Private Chat, where available, also excludes those conversations from model training. Do not treat it as a place to store passwords or banking details. xAI’s own advice is to avoid sharing sensitive personal information. Voluntary feedback can be used for training even after an opt-out.
Be careful about bringing Grok into a private conversation
Adding an AI to a chat changes who receives the conversation. X says adding @Grok gives X and its AI provider access to messages sent after it joins, until it is removed. Ask the other people before adding it to a family, health or work discussion.
The convenience is real: a bot can catch up on plans or help settle a question. But a chat that felt like a conversation among friends now includes another service.
A background bot needs a different kind of check
X describes Grok Bot as able to sign in to selected tools and carry out directed tasks. That is different from asking a question in a chat. Before giving it an account, check what it can read, change or send.
Imagine a bot arranging a birthday dinner. Finding a free evening is useful. Including a private appointment title in the invitation is unnecessary. Canceling an existing booking to make room would be a much bigger decision. Be specific about the job and keep review steps for consequential actions.
Leash can add privacy and action checks when an assistant uses supported tools through a Leash connection. It does not control Grok’s training settings, X posts or a bot’s separate browser session. Use the settings above for those.
A useful habit for every version
Before sending a screenshot, look at the edges. Is there an address, account balance, notification or private message you forgot was visible? Crop it first. You will often get the same useful answer with much less of your life attached.
Menu names change. These paths were checked against the providers’ help pages on November 4, 2026. Revisit them when you switch between X, the app and a background bot.
