Clueful Privacy Advisor is a simple security tool that will analyze the applications that you have installed on your device and give you a score that estimates the level of privacy that you maintain.
Clueful Privacy Advisor's basic function is to tell you which of your apps are potentially dangerous, and to what degree. So, you can imagine that apps like WhatsApp are labeled as 'dangerous application' since they have full online access. As you can see, it's really up to you as the user what you do with the information obtained through the analysis.
From Clueful Privacy Advisor's interface you'll have the ability to take a look at all the permissions that your different applications have. You can also easily erase them from that menu, if that's what you want to do.
Clueful Privacy Advisor is a useful tool to identify app permissions. Often, if an app is not strictly necessary for your device, it might be a good idea to get rid of it entirely.
