Is Meta Muse Safe? Your Privacy, Data and Permissions
Published 7 min read
Meta Muse privacy comes down to one trade-off. The more you connect, the more Muse can do for you, and the more it can see. Meta built strong safeguards into its personal agent, but Meta itself says Muse “isn’t immune to attack.”
The good news: you control a lot of your Muse AI privacy. You choose which apps Muse can reach and when it must ask you first. You also decide if Meta can use your chats to train its AI.
If you’re still choosing between agents, see our comparison of the best personal AI agent apps.
Five settings to check today:
- Turn off model training. Go to Settings > Data controls and deselect “help improve our AI models.” It’s on by default.
- Set approvals to “Always ask” in Settings > Permissions while you learn how Muse behaves.
- Connect only what you need. For email, pick read-only if you just want summaries.
- Avoid “Always allow” for messages to strangers or anything involving money.
- Check the activity log now and then to see what Muse did and plans to do.
Is Meta Muse safe to use?
Muse is reasonably safe for everyday tasks if you keep approvals on, but no AI agent is risk-free. Meta’s in-app warning puts it plainly: “Muse may take unexpected actions. Monitor it carefully.”
Here are the main safeguards Meta describes in its launch post and security post:
| Safeguard | What it means for you |
|---|---|
| Its own cloud computer | Your Muse runs on a private cloud computer (“Muse Secure VM”) that other agents can’t reach. |
| A guard agent | A separate “Sentinel” agent must approve anything Muse sends to the internet. |
| Hidden passwords | Muse can’t see your passwords or payment details. They’re filled in without the AI seeing them. |
| Approval prompts | By default, Muse asks before every “write” action, like sending or changing something. Purchases always need your OK. |
| One-time cards | Link by Stripe makes a new card for each purchase, tied to one store, one amount and a short time window. |
| Activity log | You get a full record of what Muse did and plans to do. |
| Bug bounty | Meta pays researchers up to $300,000 for finding security holes. |
Meta also says your Muse chats and cloud computer data aren’t shared with Meta’s ad systems.
These are strong design choices. But some are company promises, not technical locks. The next sections cover the caveats Meta itself lists.
What data Meta Muse collects
Muse can see what you tell it in chat. It can also see what you let it reach through apps, its browser and its memory.
Meta hadn’t posted a full list of Muse data as of October 2026. So this list comes from Meta’s posts and Help Center.
- Your chats and memory. Muse remembers details you mention. You can read and edit its memory files.
- Connected apps. Meta’s connectors page names Gmail, Google Workspace, Apple Health, Android SMS, Facebook, Instagram, Threads and calendar apps.
- Facebook, Instagram and Threads connect automatically if they’re in the same Meta Accounts Center as your Muse account.
- Your Mac, if you allow it. The Mac app can work with files, Messages (opt-in), Notes, Reminders, Mail and Calendar.
- Web browsing. Everything Muse does in its browser happens on its own cloud computer.
- Logins. Your sign-in details sit in a secure store on your cloud computer, out of the AI’s view.
WIRED also reported that Muse keeps “contact pages” on people in your life. Meta said Muse uses public information and what people choose to share.
How Meta uses your Muse data
Meta plans a fix for the staff-access gap. It’s called Muse Confidential VM, and it would lock your cloud computer with a key only you hold. Meta says it’s coming “later this year,” and it isn’t the default yet.
Meta Muse security issues explained
Muse has had several reported security issues since launch. Meta fixed some, and others came down to settings or how a feature was used.
| When reported | Issue | What happened |
|---|---|---|
| September 22, 2026 | Mac dictation flaw | Researcher Patrick Wardle found a flaw in the Mac app. Meta issued a hotfix, Gizmodo reported. |
| September 22, 2026 | “Human concierge” test | Reuters reported contractors handled some calls in an employee test. Meta rolled it back. |
| September 25, 2026 | Cloud computer access flaw | A researcher found a flaw through Meta’s bug bounty. Meta added a clearer warning. Whether it’s fixed wasn’t stated. |
| September 30, 2026 | Marketplace address | A YouTuber set “Allow Always” for Marketplace messages. Muse accepted a lowball offer and shared his pickup address. Meta said Muse followed instructions and asked permission. |
| October 2026 | “Contact pages” | WIRED reported Muse keeps pages on people in your life. Meta said it uses public info and what people share. |
| October 20, 2026 | Shared chats exposed | Shared Muse chats were found exposed, and Meta paused chat sharing, eWeek reported. |
We found no regulator action against Muse as of October 2026.
The bigger risk: prompt injection
Prompt injection means hidden orders on a web page or in an email. They try to trick an AI agent into doing something you didn’t ask for. Meta says prompt injection “remains an open problem in the industry.”
Meta’s defenses include marking outside content as untrusted, detection tools, and asking you before data leaves your cloud computer. That’s one more reason to keep approvals on.
How to revoke Meta Muse access to apps
To revoke Muse’s access to an app, go to Settings > Connectors and disconnect it. Meta’s connectors page says you can do this at any time.
- Open the Muse app or muse.ai and go to Settings.
- Open Connectors to see every app Muse can reach.
- Pick the app you want to remove and disconnect it.
- If you want, ask Muse to forget what it learned from that app.
- Go to Settings > Permissions and switch connectors and web access to “Always ask.”
Step 4 matters. Disconnecting stops new data. But what Muse already learned can stay in its memory or chats until you ask it to forget.
On a Mac, you can set each app to Off, Read only, or Read and interact. That’s per Meta’s Mac help page.
You don’t have to cut access completely. When Muse asks for approval, you get five choices:
- Allow once
- Allow for this task
- Allow for this site
- Always allow
- Deny

If a connector keeps failing after you reconnect it, try the fixes in Meta Muse can’t connect to apps.
How to delete Meta Muse data
To delete Muse data, ask Muse to forget specific things, or use Reset to wipe everything. Deleting a single chat isn’t enough on its own.
| What you do | What it removes | Good to know |
|---|---|---|
| Delete a chat | That conversation | Doesn’t erase what Muse learned from it |
| Ask Muse to “forget” | Related details in its memory | Best for one topic or person |
| Edit memory files | The exact lines you change | You can read and edit them yourself |
| Reset | History, files and active tasks | Permanent; it can’t be undone |
| Turn off training | Future use of your chats for training | Settings > Data controls |
A few more tips:
- Download first. Meta says you can inspect, edit and download your cloud computer files, including Muse’s memory about you. Do this before a Reset.
- Cancel separately. Deleting the app doesn’t cancel a paid plan. Cancel in Settings > Manage subscription, or in the App Store or Google Play if you paid there.
- Whole-account deletion: we couldn’t confirm a Muse-only account deletion option as of October 2026.

Frequently asked questions
Can I limit Muse's permissions?
Yes. You choose which apps Muse connects to, and for email you can pick read-only or read-and-send. In Settings > Permissions, you can switch connectors and web access from Ask for some actions to Always ask. When Muse asks, you can allow once, allow for the task or site, always allow, or deny.
How does Meta use Muse data?
Meta says your Muse chats and cloud computer data aren't shared with its ad systems. But sites Muse visits can still affect the ads you see on Instagram and other Meta apps. Meta also uses your interactions to train its AI by default. You can turn that off in Settings > Data controls.
Is Muse security better than other agents?
It's hard to say, because we haven't found an independent test that compares agent security head to head. Muse has strong design choices, like a separate Sentinel agent that approves outbound actions and a bug bounty of up to $300,000. But it has also had reported flaws and incidents. Rivals use similar approval systems.
