Turn Location Services off for system services. Several system services, such as location-based iAds,
use Location Services. To see their status, turn them on or off, or show in the menu bar when
these services use your location, go to Settings > Privacy > Location Services > System Services.
Turn off 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

You can turn off 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.

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 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 iPod touch, 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 iPod touch
using the numeric keypad, set up a longer passcode using numbers only.
Allow access to features when iPod touch is locked. Go to Settings > Passcode. Optional
features include:

Siri (if enabled; see

Siri settings

on page 37)

Passbook (see Chapter 24,

Passbook

, on page 95)

Reply with Message (see

Make and answer calls

on page 58)

Allow access to Control Center when iPod touch is locked. Go to Settings > Control Center. See

Control Center

on page 27.

Erase data after ten failed passcode attempts. Go to Settings > Passcode and tap Erase Data.
After ten failed passcode attempts, all settings are reset, and all your information and media are
erased by removing the encryption key to the data.

If you forget your passcode, you must restore the iPod touch software. See
