SAN FRANCISCO (AP) -- Just how private is that smartphone?
A Senate subcommittee will hear testimony today from an Apple vice president and a Google executive about the smartphone companies' tracking practices.
Congress is demanding details after researchers revealed last month that iPhones and Android phones were secretly keeping track of users' locations.
Apple and Google say they only record the location of Wi-Fi hot spots and cell towers to improve service, not to stalk customers, and that tracking can be turned off.
Apple said a "bug" caused the iPhone to keep location data even when tracking was disabled.
