How does Whatscan work? A lot of people who use WhatsApp already know that they can use WhatsApp on PC with the help of the WhatsApp Web.

  1. WhatsApp may be end to end encrypted, but its metadata and user contact lists are known to Facebook who own and operate it. There are also suspicions about backdoor access to WhatsApp.

    That being the case; how does the use of Whatscan introduce further potential privacy and security vulnerabilities for WhatsApp users?

    Whatscan’s developers, “World Scan & Cleaner”, do have a privacy policy (concerning the use of cookies), but their website does not identify who or where they are, and provides only a gmail address to reach them at.


    • In the whole post, we have described the use of Whatscan. If we look at the positive side, it is a good application. However, as a parent, we can keep our eyes on the WhatsApp chats of our children to protect them from any bad that could happen. We all know the scammers are everywhere and sometimes they try to manipulate the younger ones who are inexperienced.

      You gave a good point about the breach of WhatsApp data. I appreciate that!
