Seconds since last reformat, number of times clipboard was used since last reformat, seconds since last reboot, dozens of other apps installed on the phone…
On Apple devices, so much is leaked to developers, and they will use it.
No need to play games and intentionally be obtuse all across the thread. "They" are the developers. A website has far less access to a device than an app and ads are easier to block. So they wrap anything into an app to gain that access and make ad money.
> Integration with OS features is what made the app ecosystem, because of utility.
This is true of some apps, like the beer-drinking one that uses the accelerometer / other orientation sensors.
It's not true of a large number of other apps, hence the "your app could have been a webpage" charge. This is distinct from "every app could be a webpage".
Responding but never answering to anything. You were asking a bunch of questions with obvious answers that you should have known or could have discovered yourself, but expected others to dig out and chew them for you. You even went to ridiculous lengths to pretend that apps only do things "because of utility" and everything else like data collection, tracking, ads, etc. is "conspiracy". That's negative value in a conversation.
