Turn Location Services on or off. Go to Settings > Privacy > Location Services. You can turn it off 
for some or for all apps and services. If you turn off Location Services, you’re prompted to turn it 
on again the next time an app or service tries to use it.
Turn Location Services off for system services. Several system services, such as location-based 
ads, use Location Services. To see their status, turn them on or off, 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 iPad 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 iPad.
Set a passcode. Go to Settings > Touch ID & Passcode (iPad models with Touch ID) or Settings > 
Passcode (other models), then set a 4-digit passcode.
Setting a passcode turns on data protection, using your passcode as a key to encrypt Mail 
messages and attachments stored on iPad, using 256-bit AES encryption. (Other apps may also 
use data protection.)
Increase security. Turn off Simple Passcode and use a longer passcode. To enter a passcode that’s 
a combination of numbers and letters, you use the keyboard. If you prefer to unlock iPad using 
the numeric keypad, set up a longer passcode using numbers only.
Add fingerprints and set options for the Touch ID sensor. (iPad models with Touch ID) Go to 
Settings > Touch ID & Passcode. See 
, below.
Allow access to features when iPad is locked. Go to Settings > Touch ID & Passcode (iPad 
models with Touch ID) or Settings > Passcode (other models). Optional features include:
