LivaraPrivate messengerMessaging reliability explained: encrypted calls, WebRTC, multi-device sync, offline delivery, internet shutdowns and reconnect recovery.
The network is part of every conversation. These guides look at what happens when a call starts, a device reconnects, an app moves to the background, or a connection disappears.
Explore message delivery, offline outboxes, group calls and multi-device recovery. The articles separate privacy protections from the connectivity a messenger still needs.
What happens when my connection drops?
How are calls and message delivery different?
How does multi-device recovery work?
Discover how hybrid post-quantum messaging protocols use ML-KEM-768 prekey bundles to maintain forward secrecy even when your contact remains offline for weeks.
UI timers hide messages from your screen, but unencrypted payloads linger in flash storage. Discover why cryptographic key shredding is the only mathematically sound path to secure file deletion in messaging.
Discover how Livara device sync relies on transient routing metadata to deliver encrypted payloads independently, keeping your cross-device experience smooth without ever exposing plaintext to a server.
Standard voice protocols leak connection details during setup. Learn how Livara Chat secures voice call privacy by sealing WebRTC signalling inside LVR1 envelopes.
Google Firebase Cloud Messaging (FCM) delivers real-time notifications to billions of Android devices, but this convenience creates a severe structural privacy flaw. Even when an application encrypts message text end-to-end, FCM token routing exposes device identifiers, IP addresses, and exact commu
