"We will continue to work hard to strike the right balance between fulfilling our legal responsibilities and protecting our customers' privacy as they expect and deserve," statement from Apple.
Apple doesn't provide some types of information either because the company doesn't retain it or because it is encrypted, the company said. Apple also specified certain types of communications are protected, such as FaceTime and iMessage conversations, which are "protected by end-to-end encryption so no one but the sender and receiver can see or read them."
