How can you delete WhatsApp chat history permanently?

To delete WhatsApp chat history permanently, you can follow these steps:

1. Open WhatsApp on your device.
2. Tap and hold the conversation that you want to delete.
3. Tap on the "Delete" icon at the top of the screen.
4. Confirm that you want to delete the conversation by tapping on "Delete for me" or "Delete for everyone" depending on whether you want to delete the conversation for yourself or for everyone in the conversation.
5. If you want to delete all conversations, go to "Settings" > "Chats" > "Chat History" > "Delete all chats."
6. Confirm that you want to delete all chats by tapping on "Delete for me" or "Delete all chats" depending on your device.

Note that deleting a conversation from WhatsApp will only delete it from your device. If the other participants in the conversation have not deleted the conversation, they will still have a copy of it on their device.

To permanently delete the conversation from WhatsApp servers, you need to delete the conversation from all devices where it is stored. This includes your device and the devices of the other participants in the conversation.

Additionally, you can use a file explorer app to delete the WhatsApp database files from your device's storage. The database files are stored in the WhatsApp folder on your device's internal storage or SD card. To delete the database files, follow these steps:

1. Open a file explorer app on your device.
2. Navigate to the WhatsApp folder on your device's internal storage or SD card.
3. Find the database files that correspond to the conversations you want to delete. The database files are named "msgstore-YYYY-MM-DD.1.db.crypt12" where YYYY-MM-DD is the date of the backup.
4. Delete the database files that correspond to the conversations you want to delete.

Note that deleting the database files will permanently delete the conversations and you will not be able to recover them. Make sure that you have a backup of the conversations before deleting the database files.
