 This message will self-destruct in three, two, one. With WhatsApp, you don't have to be a spy to erase your messages. Let's see how. To start, open WhatsApp and then open the chat that you want to enable it in. Tap on the contact's name at the top of the window or the three dots on the right for Android phones. You'll see an option called Disappearing Messages here. Tap it and, if prompted, tap Continue. A new window will explain how disappearing messages work in WhatsApp. Select On, as required. Go back to the chat and you will see a message warning that the disappearing mode is on and all messages will self-destruct after seven days. Also, a timer icon will be put under the profile picture of your friend in the chat or friends if you turned on a group chat. Interesting, right? A few years ago, actual spies used to delete all their messages to leave no trace behind. But now with videos, audios, and a bunch of everyday text messages, it is a must for everyone to save storage space in their devices. Thank goodness that today your WhatsApp messages only disappear and they don't actually explode, right? However, this disappearing process can give anyone in the chat the chance to copy and save the messages during the seven-day window. So what if you want a message to disappear faster? Well, there is a feature in the Telegram app called Auto Delete Option. This allows you to choose between a after one day or after one week timeframe.
