About Private Processing

Copy link
Private Processing is a secure technology from Meta that enables certain optional Meta AI features, like summarizing messages and providing writing help. Private Processing enables you to use Meta AI for processing messages off-device in a confidential and secure environment where no one, not even Meta or WhatsApp, can read or access your personal messages. After Private Processing finishes responding to your request, the messages aren’t stored. Using Meta AI through WhatsApp, including features that use Private Processing, is always optional.
Note:
  • Meta AI and some experiences are currently only available in limited countries and might not be available to you yet, even if others in your country have access.
  • At this time, only English, Indonesian, Portuguese, and Spanish are supported.

How it works

Meta's Private Processing is built on top of a Trusted Execution Environment (TEE). It allows you to direct AI to process your requests in a secure and private cloud environment where no one, including Meta and WhatsApp, can access your personal messages.
Requests to Private Processing only include data that’s useful for processing the user’s request. Your request and messages are sent encrypted between your device and Private Processing, and Meta and WhatsApp can’t read them. Private Processing doesn’t retain access to or store the messages or response after your request is completed. You can learn more in our white paper.
We provide transparency when AI experiences use Private Processing. If you don’t want to use Meta AI features that use Private Processing, you can opt-out of those specific features in Settings. Learn how in this article.
If you want to prevent other users from using Private Processing features in the chats you’re in, like the ability to summarize unread messages, you can enable Advanced chat privacy. Whether or not you enable Advanced chat privacy, Meta and WhatsApp can’t read or access your personal messages that are shared to Private Processing. Learn more in this article.

Private Processing reports

You can create and download a report of your Private Processing activity at any time. Learn how in this article. Reports are generated on your device and can only be accessed by you and no one else, not even WhatsApp and Meta.
Note:
  • Meta uses AI chats consistent with Meta’s Privacy Policy. By using this feature, you agree to Meta’s AI Terms of Service. When you share your personal messages with AI features that use Private Processing technology, Meta can’t read or access the messages you have shared.
  • Responses from Meta AI are generated by artificial intelligence (AI).
