Location Services lets location-based apps such as Reminders, Maps, and Camera gather and
use data indicating your location. Your approximate location is determined using available
information from cellular network data, local Wi-Fi networks (if you have Wi-Fi turned on), and
GPS (may not be available in all areas). The location data collected by Apple isn’t collected in a
form that personally identies you. When an app is using Location Services, appears in the
status bar.
Turn Location Services on or o. Go to Settings > Privacy > Location Services. You can turn it o
for some or for all apps and services. If you turn o Location Services, you’re prompted to turn it
on again the next time an app or service tries to use it.
Turn Location Services o for system services. Several system services, such as compass
calibration and location-based ads, use Location Services. To see their status, turn them on or o,
or show in the status bar when these services use your location, go to Settings > Privacy >
Location Services > System Services.

Security
Security features help protect the information on your iPhone from being accessed by others.
Use a passcode with data protection
For better security, you can set a passcode that must be entered each time you turn on or wake
up iPhone.
Set a passcode. Go to Settings > Touch ID & Passcode (iPhone models with Touch ID) or
Settings > Passcode (other models), then set a 6-digit passcode.
Setting a passcode turns on data protection, using your passcode as a key to encrypt Mail
messages and attachments stored on iPhone, using 256-bit AES encryption. (Other apps may
also use data protection.)
Add ngerprints and set options for the Touch ID sensor. (iPhone models with Touch ID) Go to
Settings > Touch ID & Passcode. See Touch ID, below.
