Series : Muse, Meta’s AI agent · Part 3 of 3
Muse and privacy: what does Meta actually say?
Published
According to Meta, your Muse chats aren’t shared with ads — but connecting email or calendar opens access: be comfortable before you allow it.

If I use Muse, what happens to my information?
Here’s what Meta says, explained simply.
Your conversations and advertising
Meta states that your conversations with Muse and the data kept in your Muse environment are not shared with its advertising systems.
In other words, according to Meta, chatting with Muse does not mean that conversation is automatically used to choose the ads you see on Facebook or Instagram.
Do my conversations help improve the AI?
Some interactions with Muse may be used to improve Meta’s AI models.
Meta says you can turn that use off in Muse’s settings.
Where is my information?
Muse uses what Meta calls a Muse Secure VM.
You don’t need to remember the term.
Just picture a small virtual computer reserved for your Muse in Meta’s cloud.
It lets Muse keep the information it needs to work for you.
Can Meta access that information?
Today’s technology is not designed to make every form of access technically impossible for Meta.
Meta says it limits access to that data and accesses it when needed — for example to run, secure or support the service.
Meta is also working on a technology called Muse Confidential VM, meant to strengthen that separation further.
What about my passwords?
When Muse connects to other services, Meta says the information used to create those connections is protected separately.
The goal includes making sure the agent itself doesn’t need to know your password.
And the connectors?
This is probably the most important point to understand.
Muse may offer to connect other services: email, calendar and other tools.
Each connection gives it access to some new information.
For example:
Gmail only
Your emails are hosted by Google.
Gmail + Muse
You now also authorize Muse to access certain Gmail information to do the tasks you ask for.
That does not necessarily mean Meta copies your whole inbox.
It means you open Muse to access defined by the permissions you accept.
My rule
I keep it very simple:
Muse is a Meta service.
So I treat information I give it like information I give to Meta.
And when it offers to connect another service, I ask myself:
“Am I comfortable with Muse being able to access this information?”
If yes, I connect.
If not, I leave that door closed.
