Can’t speak for compass & accelerometer permissions but how do you expect auto-rotation to work in apps?
Part of auto-rotation has always been happening in the system.
It’s not the apps detecting when they need to rotate, but the system tells them about it.
Apps don’t need access to precise sensor data.
Do you really expect people to push a consent toggle every time they visit pornhub.com. Be serious.
Where did I say this?
Did you hear about remembering permissions?
I think you are overthinking this.
I am really not. You may have said that 40 years ago and it would be fine, but nowadays it’s not just scientists running professional software on their computers that’s virtually granted to not do anything wrong, we all run apps that we don’t completely trust, because it’s not possible.
If that wouldn’t be the case, we wouldn’t have permission toggles for microphone and network access.
The concern here should be can Google or any other party exfiltrate this offline data and if so, what can you do to stop it?
Oh, they can, and you will see it if you read my previous comment in whole.
Popping up a Wireshark equivalent and monitoring the chatter on your device is a good place to start. Otherwise you would be making cases for where there is no argument to be made.
If it doesn’t happen today, that does not mean it won’t ever.
Also, apps can detect if a VPN is active (which is required for capturing packets in a way that allows you to see the source app) and change their behavior. And then I doubt that you can capture broadcast messages that way, because why would that be routed through a VPN? (even when not a real one)
