Why Chinese Apps Are Dangerous ?

1] Accessing Information :-       

          Chinese apps that widely used in India are seeking excessive information from customers, according to an  independent study by an information security firm, stoking privacy concerns among experts.         - Why are they making collection of our information ?

2] Non-Relevant Permissions :-
        Most Famous Chinese apps like Helo, Shareit as well as UC Browser, ask user to provide access to camera and microphone on their smartphones even such access is not required.

 3] Why Precise Location :-
          UC browser asks for location that is precise point from where a person is searching for information. I understand that Uber or Swiggy ( Food Delivery Apps) needs to know because offers a service.
           - Why does UC Browser need to know the Location for Searching ? 

4] Sharing Information :-
          The Study, commissioned by The Economic Times, reviewed the permission sought and data shared by these type of apps to around seven outside agencies, with 69% of the data being transferred to the US.
             - TikTok sends data to China Telecom, Vigo video to Tencent and UC Browser  to its parent owned by Alibaba.
