Study Finds that 50% of Android Apps Secretly Share User Data

A study of 30 of the 358 most popular apps for Andriod devices found that 50% of them sent location information to advertisers without users’ knowledge.

Some apps dispatched location information as often as every 30 seconds, even when an application was not running. One sent this information to advertisers before it was even run for the first time. Seven apps shared unique identifier numbers, and others dispatched phone and SIM card numbers.
