Cellphone users concerned about privacy

More than half of US mobile app users say they will not use an app because privacy concerns.

A study released Wednesday from the Pew Internet & American Life Project found that 54 percent of mobile app users decided not to install one once they found out how much personal information they d have to share to do so.

Mobile apps include maps, games and other programs that help turn smartphones into portable computers.

Thirty percent of app users say they have removed an app once they found out how much information it collected about them.

The national telephone survey was conducted among 2,254 adults in March and April. It has a margin of error of plus or minus 2.4 percentage points.
