When a conversation needs extra security
For sensitive conversations, keeping no trace in the cloud and letting messages disappear automatically after a set amount of time makes secret chat a useful option whenever you need a higher level of security than usual.
The other person is notified if you take a screenshot
Secret chat sends a notification to the other person the moment you take a screenshot of the conversation -- a feature regular chats do not have. It is not a perfect guarantee, but it does add some friction against content being saved without permission.
Frequently Asked Questions
Can I see my secret chat messages on another device?
No -- a secret chat is only stored on the device it was started on and the other person's device, so logging in on a new device will not show any previous secret chats.
How can I tell a secret chat apart from a regular chat?
A secret chat shows up in your chat list with a lock icon and a green color theme, so it stands out visually from an ordinary chat.
