How can anyone track on my iPad or iPhone?
What are you asking?
Have you lost your ipod/iphone?
The only way to track and iPhone is by using Find My iPhone.
This has been stated countless times on these forms so I'm not sure why you were asking when the information is readily available to you
If your iPhone has not been jailbroken and someone has not taken your device and installed tracking software on it or you did not install and allow find my friends to track you-they can't.
