# How does automatic message deletion work?

This feature supports setting timed deletion for all message types in private chats and group chats (text/images/files, etc.).

\
**Operating Process:**

* Enter the chat details page → Select "Auto Delete" → Set the time limit.
* Once the other party successfully receives the message, the countdown begins immediately.
* After the time expires, the message will automatically be deleted from both devices and cannot be recovered.

**Important Note:** This only applies to new messages: Only messages sent after the setting is applied will trigger automatic deletion. Historical messages are unaffected.
