Can Deleted Messages Be Recovered?
Quick Answer
On most platforms, 'deleted' messages may still exist in backups, server logs, or the recipient's device. With zkChat, messages only exist in RAM and are truly gone when the session ends.
Detailed Explanation
When you delete a message on WhatsApp, Telegram, or most messengers, the message may persist in: cloud backups, the recipient's device, server databases, or even in memory on the server. Digital forensics can often recover 'deleted' data. zkChat is fundamentally different because messages are never written to disk — they exist only in RAM during an active session. When the room is destroyed (everyone leaves, timer expires, or the room is burned), the data is gone. There's no backup, no database record, no file on disk to recover. This is true ephemeral messaging.
