Hi again, I don't believe Apple endorses any anti russian or pro russian developers. I do believe however that the developers have found a way to access the data without querying the filesystem. I think StoreKit has to be explored more deeply.

I've just opened a new thread without knowing this one existed. Nonetheless, I ask myself the same question - how does SpyBuster lists all my installed apps on iOS and iPadOS ? As a developer, I've tested couple of possibilities - none of them worked. The suggestion that app uses canOpenURL and tries app URL schemas is not valid because I built my own app locally and SpyBuster is listing it. Within the app itself, MacPaw states "SpyBuster performs data analysis using standard AppStore API provided by Apple. ..." AppStore API somehow returns a list of all installed apps on the current device ?
