I assume that anything written or read on WeChat is read by the government of the People's Republic of China. I understand the risks of that.
However, I would like to understand the implications of using WeChat for other data on my device. With earlier versions of Android, you had to grant all an app's permission requests in order to use it, and WeChat demanded every possible permission. More recent versions of the OS allow users to grant or deny permissions in groups. Is there a combination of permissions which would allow WeChat to function as a chat/messenger app, but prevent it from reading other data on my device?
