Once messages are auto-deleted in Telegram, they are generally considered permanently lost and cannot be recovered. Here are the key points regarding the recoverability of auto-deleted messages:
1. Permanent Deletion: When messages are set to auto-delete, they are removed from both your device and Telegram's servers after the specified time. This means that once deleted, they cannot be restored through any official means or by contacting Telegram support[1][5].
2. Recent Deletions: If a message is deleted, Telegram does provide a brief window (typically five seconds) during which you can undo the deletion. However, this is only applicable immediately after the message is deleted and does not apply to auto-deleted messages that have already been removed from the chat[2][4].
3. Data Recovery Tools: While some third-party data recovery tools claim to recover deleted messages, they typically do not work for messages that have been auto-deleted, as these messages are not stored anywhere after deletion[2][5].
4. Backup Options: If you have previously backed up your Telegram data (for example, using Telegram Desktop's export feature), you might be able to retrieve some information, but this would not include messages that were specifically set to auto-delete after a timer[1][2].
In summary, auto-deleted messages in Telegram are not recoverable, and users should take care when setting up auto-deletion if they wish to retain important conversations.
