Overview
- The feature is live for EU users on iOS and Android phones and must be enabled in settings, with no support yet for web, desktop, or tablets.
- At launch it works only with BirdyChat and Haiket, supports one-to-one conversations with basic media, and excludes group chats plus WhatsApp-specific features like status updates and disappearing messages.
- Eligibility depends on having a phone number from a DMA-covered EU country, and switching to a non‑EU number removes access.
- Meta says end-to-end encryption is preserved for cross-service messages, while noting it may collect metadata such as IP-based general location and last-online times.
- Third-party apps receive the sender’s phone number and apply their own terms and privacy policies, blocking does not carry across services, and Signal and Threema have declined to participate.
