Internal Apple documents reveal new details about its app policies SHARE Internal Apple Inc. documents released as part of the iPhone maker’s legal battle with video game maker Epic Games Inc. have revealed new details about its App Store policies and user retention strategy. The documents, The Verge reported today, indicate that Apple had avoided making iMessage available on Android to reduce the chance of users switching to Google LLC’s operating system. It also appears that a senior engineer expressed doubts internally about the effectiveness of the company’s efforts to protect users from malicious iOS apps. The details were included in “proposed findings of fact” filings Apple and Epic Games submitted this week as part of their court dispute. The legal battle started last year after Fortnite, a popular video game developed by Epic Games, was removed from the App Store because the company allowed users to make in-app purchases without going through Apple’s payment system. The App Store terms of service only permit in-app purchases using Apple’s payment system, a rule Epic argues is anticompetitive.
