Short answer: Meta’s reviewed official documentation does not establish a global opt-out for using direct Meta AI chats to personalize responses or content. Meta does say information you share in a chat may be used to personalize replies within that conversation. If you want to limit that in-chat use, avoid sharing sensitive details; check the current privacy and AI controls in the specific Meta app you use, but do not assume an unrelated setting blocks chat-based personalization.
What Meta says it uses chats for
Personalizing replies in a conversation
Meta says information shared with AI may be retained and used to personalize responses or provide relevant information within that conversation. This is in-chat context use, not the same thing as using AI interactions to personalize what you see elsewhere. Meta’s privacy explainer describes this use. Avoid putting sensitive personal details into a chat if you do not want them used as context for replies.

Personalizing content and ads across Meta
In an October 1, 2025 announcement, Meta said it would begin using interactions with AI at Meta to personalize content and ads starting December 16, 2025, including posts and reels. That is broader than tailoring replies inside the chat. Meta’s announcement describes the use, but the official documentation reviewed here does not establish a global setting to opt out of personalization based on direct AI chat messages. Read Meta’s announcement.
What you can do now
Limit what you share
For the specific in-chat use Meta describes, the practical precaution is not to share information you would not want used to shape replies in that conversation. This does not amount to an opt-out from broader personalization.

Check controls in the app you use
Review the current privacy and AI controls in the particular Meta app and account where you use Meta AI. Labels and availability can change, and may vary by app or account. The official pages cited here do not verify a product-by-product control that stops direct chat messages from being used for personalization, so do not rely on a setting unless its current description explicitly covers that use.
Settings that are not confirmed direct-chat opt-outs
Activity from other businesses
Meta’s June 2026 announcement about “Activity from other businesses” concerns information that businesses share with Meta. Meta says that information may be used to personalize Feed and AI responses and describes an expanded setting for managing that use. It does not establish that the setting controls messages you send directly to Meta AI. Meta’s June 2026 explanation covers the business-shared activity setting.

Accounts Center and general Facebook privacy settings
Meta says information across accounts added to Accounts Center may support personalized experiences such as ads and suggested accounts. Its documentation does not say unlinking accounts stops personalization based on Meta AI chats. Likewise, Facebook’s general privacy settings page covers audience, visibility and information management, but does not document a specific direct-chat personalization opt-out. Accounts Center information and Facebook privacy settings describe those broader controls.

Muting Meta AI or changing microphone access
The sources reviewed do not establish that muting or hiding the Meta AI interface changes how chat data is used. Microphone permissions are a separate matter: Meta says it does not use the microphone without permission and uses it only while a feature that needs it, such as a voice chat with Meta AI, is actively in use. Microphone controls should not be treated as a chat-personalization opt-out. Meta’s privacy policy discusses microphone use.
