Calls, sync & reliabilityKeep the
conversation going.

Messaging 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.
