Pretty much all Apple devices and systems feature encryption in some way. If you use FileVault 2 on a Mac, your system is encrypted. iOS devices are also automatically encrypted and secured by your passcode, fingerprint or facial data.
When data is sent to Apple’s servers, it’s also end-to-end encrypted. That goes for your location data in Maps or the contents of the texts you send in Messages. You can rest assured that, in pretty much every way, Apple tries to keep your data away from prying eyes. (That includes itself, since even it doesn’t have the keys to unlock your data.)
