Muse AI data privacy may expose friends without their consent

The short version

Muse AI asks users to grant access to vast personal data, and it can extend to people the user interacts with.
Critics warn this creates mass surveillance of friends, family, and acquaintances without their explicit consent.
Privacy advocates call out “dark patterns” that push users to share more than they realize.
Readers should understand what data their own devices are sharing and adjust settings to limit data exposure.

Muse, Meta’s new AI assistant, asks for broad access to your data and, crucially, data about people you know. That means your privacy could hinge on how your friends configure their own devices. Critics warn this is a shift toward mass, consented-but-hidden data collection, where settings nudged you toward sharing more than you realize. If you care about privacy, start by checking Muse’s permissions and limit what you share. Talk to friends about what data you both allow, and consider turning off features that pull in others’ information.

What it means for you: your AI assistant could act on data that isn’t yours alone, which could affect everything from personal recommendations to sensitive conversations. What happens next is up to how Meta tunes controls and how users style their privacy habits.

Muse, Meta’s new AI personal assistant, has sparked a wave of privacy concerns by design. The app asks users to grant access to a broad set of data, from bank accounts and passwords to chats and contacts, and it touts the ability to act on behalf of the user. The twist many readers will find unsettling: much of the data powering Muse’s moves can belong to people who never asked to be part of this digital assistant’s life.

Why this matters to you is simple. If Muse can use information about people you know, your own privacy is tied to theirs. It isn’t just about what you opt in to; it’s about what your friends, coworkers, or even a barista you once chatted with might have inadvertently shared with Muse through interactions with you. That extends your data footprint far beyond your own device and your own choices.

Several observers describe Muse as part of a broader trend: AI agents designed to automate tasks by pulling in a wide net of personal data. The problem isn’t just what the app can do today, but what it could do tomorrow as more data is fed into the system. Critics say such assistants use people’s data in ways users often don’t realize or fully understand, because the interface nudges people toward sharing more than they intend.

What readers should watch for right now

First, understand what you’re consenting to. Muse offers opt-in settings, but critics say the controls can be hard to find or understand, and the default prompts users to share more than they intend. Second, remember that privacy is a social issue here: data about you may become available to the AI through someone else’s device or account. Finally, be mindful of what data you reuse across apps; once a piece of information is in the AI’s model, it can influence future responses and actions.

Which data could be exposed and how it’s used

Supporters say Muse uses data it is given and data it can infer from your public information or stated preferences. Critics warn that because the agent models people in your life, it can create a detailed portrait of others you interact with, even if they never explicitly consented to be part of Muse’s data network. The result could be highly personalized recommendations, schedules, or actions based on information that you did not realize was being shared beyond your control.

The catch nobody mentions (yet)

Experts point to “dark patterns” in the app’s design that nudge people toward sharing more data than they intend. And as Muse builds a broader profile of your life, the potential for unintended data leakage grows, especially for the people you discuss private matters with or those who aren’t comfortable being part of an AI’s learning set.

What this means for everyday life

For most users, the practical question is simple: do you want an AI that can pull data from other people you know to help you manage tasks? If privacy is a priority, you’ll want to review permissions carefully and limit access to only what you’re comfortable sharing. That includes considering who in your life might have access to your data through your use of Muse and how it could influence future interactions with the AI.

What you can do now

Check the Muse privacy settings and tighten permissions, especially anything that touches messages, contacts, and location data.
Limit sharing with the app to the minimum you’re comfortable with, and opt out of data sharing with third-party services where possible.
Discuss with family and friends how your data might be used if someone you know uses Muse, and consider whether to disable the feature that shares data beyond your device.

Quick answers

What data does Muse collect from me?

Muse asks for a broad range of data, including sensitive items like passwords and bank information, as well as your chats and contacts. It can also pull in information about people you know.

Can I stop my data from being shared by others’ Muse use?

No. If someone you know uses Muse and shares data with it, that data can feed into Muse’s model in ways you didn’t consent to.

What should I do if I’m worried about privacy?

Review permissions, limit data sharing to what you’re comfortable with, and talk to friends about data sharing implications when using AI assistants.
