Overview
- The EU-only feature has begun rolling out on iPhone and Android as an opt-in setting, with no support yet for desktop, web or tablets.
- At launch, cross-app messaging is limited to one-to-one conversations with Birdychat and Haiket users and supports text, images, videos, voice messages and documents, excluding status updates and disappearing messages.
- Eligibility is tied to an EU-registered phone number, and switching to a non‑EU number removes access to third-party chats.
- Message contents remain end-to-end encrypted, while metadata such as IP-based location, last online time and usage duration is collected, and connected services receive the sender’s phone number.
- Signal and Threema are not participating, the rollout is staggered over the coming months, and Meta flags higher spam risks with separate block lists across different apps.
