The iPhone manufacturer has told them to pull the code responsible or risk having their apps banned from the store. The issue came to light after TechCrunch reported that hidden code in some apps was recording users without their permission. Even worse, the code - which comes from a company called Glassbox - has not been masking some sensitive information. Many apps tested didn't send personal information but none of them warned users that their screens were being recorded. The idea is to collect data about how users interact with apps and to then improve the experience.
