One of the important new features coming with iOS 16 is Safety Check. Designed as a tool for those at risk for domestic abuse, Safety Check for iPhone allows users to immediately revoke access other people and apps have to their location and perform a security review.
Apple is known for its focus on security and privacy, and Safety Check in iOS 16 follows a Personal Safety User Guide that was first published in late 2020 and updated in 2022. It features a number of steps to take to limit iPhone access, limit sharing, and stop iPhone from sharing location data.
