Data mining proof



How can I proof for myself which app or the OS itself is collecting my data and sending it ‘home’ ?

To trust the FOSS developer is OK, but a own proof is better


A while back there was a topic with the same question:


Ah, Ok, haven’t seen. But I hope, that we will get some answers now.And I’m not meaning e alone, I mean also every app I have installed.


My reply in the other thread is also valid regarding verification of apps.


Help, I have seen, tx
