What personal data can the ios application receive?

Question

iOS

Recently, I often read news that mobile application developers receive a huge amount of user data. What data can an ios app developer get? Can I get a phone number, AppleID or other personal information?

Answer 1

Are you joking like that?
Apple pays a lot of attention to privacy. The application has access to some characteristics of the phone and the environment, and even then not all, and it gets access to personal data only after the appropriate permission from the user.
For example, despite the information about ip when connecting to your WiFi point, the application cannot find out its mac address. It used to be possible, but now the shop has already been closed.
Is that through the identification of the device, you can pull out some data. This is when the developers of two different applications exchange information (with or without an intermediary) about their customer base, and it turns out that the user of your game has recently used another application or visited some site. But this already goes beyond the protection of PD by Apple, which continues to put spokes in the wheels of application developers (but without fanaticism).
Well, high-profile articles, when some kind of bug or hole is found, are loud precisely because Apple focuses on security, but in fact there is a leak. In addition, many journalists try to find something that can be submitted with a beautiful yellow headline. And "hole in iOS" sounds louder than "hole in Android".
Of course, there are also real holes, and sometimes huge ones. But I’ll tell you in secret that your PD is not a secret for, for example, the state anyway. Even here I, with certain connections and money, can access your whatsapp correspondence. So if you have some really big secrets, then you should not rely on Apple, you need to make additional efforts to ensure information security.
