Muse trains Meta models on your conversations: the data collection toggle is on by default
It can be turned off with a single toggle in settings, and training is disabled even for past conversations.
Muse asks you to link a payment card before the first conversation. Then it asks for access to your email, calendar, and smart home.
The assistant is only as useful as the access you give it to your life. Muse's App Store listing declares 13 categories of collected data, including financial information, health data, and precise location, and names third-party advertising as a collection purpose (18.09.2026).
The switch lives in settings. Settings → Data controls, with a toggle for using interactions to improve AI. Turning it off applies retroactively to past conversations too (Meta help center, 08.09.2026). Until you change it, chats are used to train Meta's models.
Meta promises isolation. Conversations are stored in Muse Secure VM and do not flow into advertising systems; before training, names, email addresses, and phone numbers are removed, and interactions are decoupled from the account. The boundary is stated there too: the architecture "does not prevent Meta from accessing data when necessary to support, protect, or operate the service," while employee access is governed by operational policies rather than technology.
The app continues Meta's approach: data collection for training is enabled by default, and users must turn it off themselves. Muse launched on 8 September 2026 only in the US — web, iOS, Android, and chats in WhatsApp — and a Mac version arrived on 17 September, where the agent works with files, email, calendar, and notes in native apps.
You cannot officially connect from Russia. The rollout is US-only, and before the first conversation Muse asks you to link a card, which makes it a matter of paying for an overseas service. The free tier includes a remaining-usage counter; paid plans cost $20 and $100 per month (TechCrunch, 08.09.2026).
Meta promised to bring Muse to its AI glasses.
