Privacy Checkup: Decide who can see what
WhatsApp’s Privacy Checkup tool is the quickest and easiest way for you to control who can see your information. By going to Settings and under Privacy, you can decide who should see your profile photo, status, last seen and bio. You can also choose who can add you to groups and who can call you. Setting Last Seen and Status to ‘Nobody’ gives you an extra layer of security when receiving messages from strangers.
