Apple has responded to queries by US lawmakers over the location data the company collects by writing a 13 page letter, tech news site eWeek reported on Monday.
In its reply to members of the US House of Representatives Ed Markey from Massachusetts and Joe Barton from Texas, Apple said it collects encrypted location data every 12 hours from iPhones running OS 3.2 and iOS 4, via wireless broadband.
“When a customer’s device sends Wi-Fi, cell tower, GPS, or diagnostic location information to Apple, it does not include any information identifying the particular device or user,” explained Apple’s General Counsel, Bruce Sewell, in the company's written response.
Sewell also stated that any data collected by the company via the devices is kept for a maximum of six months, and that no information is used or passed on to a third party without the user’s permission.
Barton and Markey have thanked Apple for responding to their queries and sharing information about their data collection practice, but have still expressed some misgivings.
Barton said: "While I applaud Apple for responding to our questions, I remain concerned about privacy policies that run on for pages and pages."
