What Is Ephemeral Messaging?
Quick Answer
Ephemeral messaging means messages automatically disappear after being read or after a set time, leaving no permanent record on any device or server.
Detailed Explanation
Ephemeral messaging is designed around the principle that communication shouldn't persist indefinitely. Unlike traditional messaging where your entire history is stored forever (and can be breached, subpoenaed, or discovered), ephemeral messages have a defined lifetime. There are different levels: Snapchat claims ephemerality but stores data on servers. WhatsApp's disappearing messages still exist in backups. Signal's disappearing messages persist until the timer runs. zkChat's ephemerality is the strongest: messages exist only in RAM during active sessions, rooms auto-destroy when empty or when the timer expires, and one-time messages delete after a single read. Nothing is ever written to disk.
