Facebook + Instagram
At the top of the list are Instagram and Facebook, to no one’s surprise. Both Instagram and Facebook collect a total of 79% and 57% of personal data, respectively. On top of that, both apps practically want access to everything on your iPhone, like purchase history, location, contact information, search history, financial information, and much more.
There are many other apps that ask and use your personal data, but these apps are the ones you should worry about the most. Fortunately, with iOS 14.5, you have a little more control over your information. But you might still consider deleting these apps and games if you worry about your data.
