If you let Siri know who you are, you can get personalized service—like, “remind me when I get home to call my wife.”
Tell Siri who you are. Fill out your info card in Contacts, then go to Settings > General > Siri > My Info and tap your name.
Be sure to include your home and work addresses, and your relationships.
Note: Location information isn’t tracked or stored outside iPhone. If you don’t want to use Location Services, go to Settings > Privacy > Location Services to turn it off. You can still use Siri, but Siri won’t be able to do anything that requires knowing your location.
