Many U.S. cellphone users say they have decided not to use an app on their phone because of concerns about privacy.
More than half of Americans who use apps say they have decided not to install one once they found out how much personal information they'd have to share, according to a study released Wednesday from the Pew Internet & American Life Project.
Mobile apps include maps, games and other programs that help turn smartphones into portable computers. Some apps, for instance, want to know a person's location using the phone's GPS function.
Thirty percent of app users say they have removed an app once they found out how much information it collected about them.
Android and iPhone users were equally likely to remove or not install an app because of concerns over how much personal information it collected, according to the study.
In all, 88 percent of adults said they own some sort of a mobile phone, and 43 percent of that group downloaded applications to their phone. That's up from 31 percent in 2011.
