Apple revamps the privacy page on its website
Apple adds that it doesn't collect the information created when users ask questions for Siri to answer. And Apple's Differential Privacy means that data belonging to an iPhone owner is scrambled, added to the data belonging to millions of other iPhone users, and examined for general patterns. According to Apple, these patterns help it discover the most popular emoji, the best suggestions for QuickType, and energy consumption rates for the Safari mobile browser.
Other privacy related topics on the page include the use of encrypted data, and how app developers must follow "strict guidelines" when it comes to handling your personal information, or face having their apps removed from the App Store.
There is no mention of Face ID on the page. That is the technology that will be found for now only on the Apple iPhone X. It uses your face to unlock the handset and verify the identity of the phone's user.
