Go to Settings > Privacy > Profile Photo and set it to "My Contacts" to prevent strangers from viewing your picture.

After the fake loading sequence, the site will claim the DP is ready but require you to complete a survey, download an app, or click on ads to "unlock" the image.

To ensure your own display picture (DP) stays private, follow these steps in the WhatsApp Help Center : Go to > Privacy . Tap on Profile Photo .
