Disable Find My iPhone
Find My iPhone helps users locate a lost iPhone or iPad.
It also lets someone lock their device if it is stolen.
Apple devices in the one household often share the same iCloud account.
This might mean that a perpetrator can have access to the location of all iPhone and iPad users within the household.
