Overview

Signal is the gold standard for private, end-to-end encrypted messaging. It supports text, voice calls, video calls, and file sharing. Signal collects almost no metadata and its protocol is open and independently audited.

Designed for everyday users who value privacy, Signal is a drop-in replacement for SMS and MMS with a familiar interface.
