How can you delete WhatsApp messages permanently from server?

WhatsApp does not provide a direct way for users to delete messages permanently from their servers. Once a message is sent, WhatsApp encrypts it and delivers it to the recipient(s). After it is delivered, WhatsApp does not retain the message on their servers.

However, there are a few things to keep in mind regarding message deletion on WhatsApp:

1. **Deleting Messages Locally**: You can delete messages you've sent or received from your own device. This action removes the message from your chat, but it does not affect the recipient's chat. If you want to delete a message for everyone in the chat, you can use the "Delete for Everyone" option within a specific time frame after sending the message.

2. **Delete for Everyone Feature**: WhatsApp allows you to delete messages for everyone in a chat within a limited time window (about an hour). This feature helps in removing accidental messages sent to the wrong person or group. To use this feature:
   - Open the chat containing the message you want to delete.
   - Tap and hold the message or messages to select them.
   - Tap the trash can icon at the top of the screen.
   - Select "Delete for Everyone" to remove the messages from both your chat and the recipient's chat.

3. **Data Retention**: Even though WhatsApp does not store messages on their servers after delivery, it's important to note that users may have backups of chats stored in cloud services like iCloud (for iPhone users) or Google Drive (for Android users). If you have backed up your chats to these services, deleting messages from WhatsApp will not delete them from your cloud backups automatically.

4. **Third-Party Tools**: There are third-party tools that claim to delete WhatsApp messages from servers, but their effectiveness and reliability are questionable. Be cautious with such tools as they may compromise your data security.

In summary, while WhatsApp provides options to delete messages from your device and from the recipient's device within a limited time frame, it does not offer a direct method for users to delete messages permanently from their servers after delivery. For privacy and security reasons, it's essential to manage your messages carefully and be aware of the implications of data retention policies on cloud backups.
