The finding comes as the U.S. Senate held a hearing on mobile privacy issues this week following much-publicized reports that iPhones, iPads and Android devices collected detailed information about users' locations. One focus of the inquiry by the Privacy, Technology and Law Subcommittee of the Judiciary Committee was the privacy of personal information collected and used by apps on mobile devices.
Discussion of that topic led to questioning on the lack of privacy policies for apps. An investigation earlier this year by The Wall Street Journal found that 45 of the top 101 iPhone or Android apps analyzed did not provide privacy policies on their sites or inside the apps at the time of testing.
The group's own analysis includes looking at the top paid iPhone and Android apps as of May 10, as well as industry standard reporting from mobile analytics firm Distimo. In addition to examining developer Web sites for app privacy policies, it also downloaded a sample of the paid apps to determine whether at any time during the download or installation process a policy was presented to the user.
In connection with the Senate hearing, the deputy director of the FTC's Bureau of Consumer Protection said in a prepared statement this week that the agency is also investigating mobile privacy, including children's privacy.
