In essence, Sewell explained that Apple collects information on users who have enabled location-based services, those who have agreed to receive iAds, and those who have agreed to receive diagnostic information on their devices. The data is collected every 12 hours and encrypted before it is sent to Apple via Wi-Fi. According to PCWorld.com:
Attached to the GPS data is a random identification number generated by the phone every 24 hours. The information is not associated with a particular customer.
Sewell also explained that users who wish not to send geographic data to Apple can disable location-based services on their devices.
The lawmakers' reaction to the responses was mixed, PCWorld.com writer Nancy Gehring says. Markey was satisfied that Apple obtained user consent before collecting the information and also gave users different means of "opting out" of the data collection. Barton, on the other hand, was not convinced. He noted:
I remain concerned about privacy policies that run on for pages and pages.
Whether these or other lawmakers will probe further on the issue remains to be seen.
