I dont think they can break the sandbox. because then apple would have most likely removed them from the store already.
However what they can do is everything the app can do:
- get your contacts
- get your messages
- get your photos
- get your location
- get the people you chat with
- read the stati of your contacts
therefore i would assume with the right tools you can directly identify a phone use, its social circle, most talked topics on an "encrypted messenger" and since the messages are right there: sentiment analysis of conversations had and therefore social status of the pople you chat with
actually its quite terrifying. but so is the idea also that our faces and words are being handed through the world by a tech company without international regulations...... soooo business as usual =)
