Overview

Signal is widely regarded as the gold standard for private messaging. Built by the Signal Foundation, a non-profit organization, it uses the open-source Signal Protocol to provide end-to-end encryption for all messages, voice calls, and video calls.

Unlike many competitors, Signal does not monetize user data, display ads, or track user behavior. The app supports disappearing messages, screen security, relay calls to hide your IP address, and sealed sender technology that conceals even who is messaging whom. It is available on iOS, Android, Windows, macOS, and Linux, making it one of the most accessible truly private messaging platforms available today.
