When you use Find My iPhone, your device’s location, as well as information about your device and your account will be sent to and retained by Apple so Apple can provide you with the service.
While in Lost Mode, your device can keep track of where it has been and report back so you can view its recent location history, right from the Find My iPhone app.
Find My iPhone will help you locate your missing device on a map, remotely lock it, play a sound, display a message, or erase all the data on it.
Please note that Find My iPhone must be enabled in iCloud settings on your device before you can locate it with this app.
If you misplace your iPhone, iPad, iPod touch, or Mac, the Find My iPhone app will let you use any iOS device to find it and protect your data.
Your device’s location is only sent to Apple if you actively request the location of a device or accessory.
If you choose to enable the Send Last Location feature, your device’s last known location will be automatically sent to Apple any time your device’s battery reaches a critically low level.
For missing iOS devices, Find My iPhone also includes Lost Mode.
You can create a free Apple ID to use with iCloud on your iPhone, iPad, iPod touch or Mac.
Lost Mode locks your device with a passcode and can display a custom message and contact phone number right on the Lock Screen.
