PrivacyPrivacy settings let you see and control which apps and system services have access to Location
Services, and to contacts, calendars, reminders, and photos.
Location Services lets location-based apps such as Maps, Weather, and Camera gather and
use data indicating your location. Your approximate location is determined using available
information from local Wi-Fi networks, if you have Wi-Fi turned on. The location data collected
by Apple isn’t collected in a form that personally identies you. When an app is using Location
Services, appears in the menu 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 location-based
iAds, use Location Services. To see their status, turn them on or o, or show in the menu
bar when these services use your location, go to Settings > Privacy > Location Services >
System Services.
Turn o access to private information. Go to Settings > Privacy. You can see which apps and
features have requested and been granted access to the following information:
•Contacts
•Calendar
•Reminders
•Photos
•Bluetooth Sharing
•Microphone
•Twitter
•Facebook
You can turn o each app’s access to each category of information. Review the terms and privacy
policy for each third-party app to understand how it uses the data it’s requesting.
SecuritySecurity features help protect the information on your iPad from being accessed by others.
Use a passcode with data protection
Initially, iPad doesn’t require you to enter a passcode to unlock it. You can set a passcode that
must be entered each time you turn on or wake up iPad.
Set a passcode. Go to Settings > General > Passcode Lock and 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 o 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.
Allow access to features when iPad is locked. Go to Settings > General > Passcode Lock.
Optional features include:
•Siri (if enabled; see Siri settings on page 38)
