What concerns me is:
> applications should obtain explicit approval
Why not change that to a MUST? I'm pretty sure that's a legal requirement anyway.
> all data was collected for research purposes with users’ explicit approval and consent.
I don't trust you, sorry. Please show me the UI/forms you used to gain consent. I cannot have sex with someone because they agreed to it in a lengthy, detailed and complex agreement buried in complicated legalese.
> users were allowed to opt out at any point and request their data to be deleted.
And I can request for you to go...yourself with the BS you throw at developers every now and then, doesn't mean you're going to, does it?
I'm getting more and more closer to throwing the smartphone out the damn window, I'm not paying for a device so you can log my every interaction within the world in 4k.
