Not happy with answers Apple provided earlier this month regarding iOS privacy practices, a Congressional committee has requested Apple send a representative to Capitol Hill to explain in person, reports “PC World” (http://macte.ch/J9Q7g).

Apple needed to provide more detailed information as to what the company is doing to protect user privacy on its mobile devices, Rep. Henry A. Waxman, ranking member of the Energy and Commerce Committee, and Rep. G.J. Butterfield, ranking member of Subcommittee on Commerce, Manufacturing, and Trade, wrote in a letter to Apple CEO Tim Cook on March 14. The House Committee on Energy and Commerce originally sent a letter to Apple February 15 asking about iOS privacy practices. The representatives said Cook’s response on March 2 was insufficient, notes “PC World.”

Last month Waxman and Butterfield sent a letter to Apple, following complaints that a smartphone application dubbed Path was collecting address book data and storing it on remote servers without permission. While Path has been tweaked to address the issue, Butterfield and Waxman have noticed that parts of Apple’s iOS developer website says Apple provides a comprehensive collection of tools and frameworks for storing, accessing and sharing data.

They came up with a list of questions they wanted Apple to answer about all this. You can find the questions at http://macte.ch/SQSDW .
