Signal

Overview

Signal is a free messaging platform that uses state of the art end to end encryption (based on the open-source Signal Protocol) for all messages, voice calls, video calls, media, and files so that only the sender and recipient can read them. It supports text and group chats, voice and video calls, disappearing messages, encrypted stickers, and cross-platform use on mobile and desktop without ads or tracking.
