Privacy
Privacy 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, Camera, and Passbook 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 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 location-based
ads, 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
•
Calendars
•
Reminders
•
Photos
•
Bluetooth Sharing
•
Microphone
•
Camera
•
Health
•
HomeKit
•
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. For more
information, see support.apple.com/kb/HT6338.
Security
Security features help protect the information on your iPod touch 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 iPod touch.
Set a passcode. Go to Settings > Passcode, 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 iPod touch, 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 iPod touch
using the numeric keypad, set up a longer passcode using numbers only.
