The South Korean Communications Commission said it has had launched an inquiry into Apple's tracking of its users of iDevices to assess whether the snooping violates its rules on personal privacy.
The inquiry follows the revelation that Apple tracks its users where-ever they go.
The gadget maker said a year ago that it "must have access to the comprehensive location-based information," in order "to provide the high quality products and services that its customers demand." That statement was given by the company's general counsel Bruce Sewall in response to a question by U.S. Congressmen Edward J. Markey and Joe Barton.
No-one paid the missive much attention at the time until it was revealed last week that many of Apple's iDevices track their users' movements over extended periods of time.
The South Korean telecoms regulator said it had a number of questions for Apple and has sent a sent the company a list of points it wants clarified.
The regulator said it wants to know why the tracking data is recorded, why it isn't encrypted and whether users can opt out from being snooped on.
Apple is yet to make any sort of comment on the revelations.
