End-to-end encryption is a privacy feature in messaging apps where messages are encrypted as they are sent from the sender's device and remain encrypted until they are decrypted on the recipient's device. This means that only the sender and the intended recipient can read the contents of the message, even if intercepted by others during transmission.
End-to-end encryption does not delete messages. Instead, it ensures that the messages remain confidential and cannot be accessed by anyone other than the sender and the intended recipient. The messages are stored on the sender and recipient's devices and remain encrypted until decrypted upon receipt. However, users must keep in mind that if they delete the messages from their device, they will be permanently deleted and cannot be retrieved.
