Meta's Muse Builds a File on Your Entire Family — For Free

Millions have downloaded Meta's AI agent Muse. Getting it to do your bidding comes with a price tag you didn't agree to: a detailed profile of every friend and family member in your contacts.

Meta's privacy policy for Muse is explicit. The agent collects your contacts, your messages with those contacts, and your interactions with them. It builds a picture of who they are, what they talk about, and how they relate to you. It stores that data.

This isn't a side effect. It's how the tool works. You can't use Muse without it reaching into your private conversations and mapping your social circle.

The app is free. There's no paywall. The cost is your data — and the data of everyone you've ever texted.

Meta says it uses the information to make Muse more helpful. That means your aunt's birthday, your cousin's business, your friend's health struggles — all fed into a model that can summarize, predict, and potentially share that knowledge elsewhere.

There's no toggle to opt out of the social mapping. You accept it or you don't use the app. That's the deal.

This is the same playbook Meta has used for years. Free app, data harvest, profit from the pattern. But this time it's not just your own data. It's the data of people who never agreed to anything. They didn't sign up. They didn't see the terms. They just got pulled into your contact list and turned into a profile.

The app is available on iOS and Android. Download numbers are in the millions. The privacy cost is invisible to most users because it's buried in the fine print.

Why this matters for us: When Meta builds a file on your abuela's health or your primo's side hustle, that information can be used, shared, or sold — and they never asked anyone for permission to touch that data.
