READ PHONE STATE AND IDENTITY
Allows the app to access the phone features of the device. An app with this permission can determine the phone number and serial number of this phone, whether a call is active, the number that call is connected to and the like.
So is it going to store my phone number in a database somewhere? Is it simply going to avoid trying to send data if a phone call is active? We, as users, have no way of knowing. And, if they made the permissions even more granular, we would never be able to successfully wade through all of them. I need someone smarter than me to fix the design. But the design as it exists today is largely useless.
