Our iPhones are the keys to our digital lives, holding our most private photos, conversations, and financial data, among much else. That’s why Apple goes to such lengths to help us protect our privacy and security. But we all have people with whom we share some level of access, whether that means shared photo albums, shared locations, or even shared passcodes. Unfortunately, trusted relationships sometimes disintegrate, occasionally in ugly ways that could endanger your safety. If that happens, you want to make sure to disable whatever sharing you had with such a person. You can always turn to us for help, of course, but Apple has now published “Device and Data Access when Personal Safety Is At Risk,” a clear, sensible PDF guide that explains the many ways of sharing data using Apple devices and services, along with details on how to see with whom you’re sharing—and how to stop that sharing. Even if you aren’t worried about your safety in this regard, it’s worth reading the guide and revisiting your settings to make sure you’re sharing only with intended people.
