Disappearing messages. To enable this feature, you need to briefly press the icon with the name of the interlocutor and then click on "Messages" - "Temporary Messages".
Message read report. You can make it so that the person you're talking to can't tell if your message has been delivered. There are two ways: through "Settings" ("Account" - "Privacy" - "Reading reports") and by installing a special widget on the smartphone screen (only suitable for Android devices).
Ban your profile picture. In WhatsApp you can hide your avatar from everyone or from some people. To do this, go to "Profile photo" through the "Account" - "Privacy".
