Can I set up Telegram to automatically delete old messages

Enable Auto-Delete for All Chats

1. Open the Telegram app and go to Settings.
2. Tap on "Privacy and Security".
3. Select "Auto-Delete Messages".
4. Choose a self-destruct timer for all new chats - options include 24 hours, 1 week, 1 month or a custom time period up to 1 year[1][2][5].
5. Tap "Enable Auto-Deletion" to confirm. All new messages in future chats will now be automatically deleted after the specified time[1][2].

Enable Auto-Delete for Individual Chats

1. Open the chat where you want to enable auto-delete.
2. Tap on the recipient's name at the top of the chat.
3. Tap the three-dot menu icon and select "Auto-Delete"[2][4].
4. Set the time period after which messages in this chat will be automatically deleted[2][4].

A few key points about Telegram's auto-delete feature:

- It only applies to messages sent after the timer is set, not existing chat history[6].
- In groups and channels, only admins can enable or modify the auto-delete timer[6].
- All messages show a countdown to their deletion time - tap on Android or press and hold on iOS to view[6].
- You can turn off the self-destruct timer anytime by disabling it in the "Auto-Delete Messages" settings[5].

So in summary, Telegram makes it easy to automatically clean up old messages to keep your chats organized and your data private. The auto-delete feature works for both individual chats and all new conversations.
