• Sorry, but you are wrong. They will still collect all they can collect, but when you reject a permission the OS literally blocks the API access from the app.

    For example, a common evil behavior for apps like this is to do passive listening through your device’s microphones so that they can target you for ads based on your day-to-day conversations. However, if you reject microphone access, the app will not be able to do this. The OS will literally block it from accessing the APIs for the microphone.

    iOS has done this for quite some time. I assume Android is recently doing something similar, although not up to par.
