More than half of mobile application users have uninstalled or avoided certain apps due to concerns about the way personal information is shared or collected by the app, according to a nationally representative telephone survey conducted by the Pew Research Center’s Internet & American Life Project.

In all, 88% of U.S. adults now own cell phones, and 43% say they download cell phone applications or “apps” to their phones. Among app users, the survey found:

• 54% of app users have decided to not install a cell phone app when they discovered how much personal information they would need to share in order to use it
• 30% of app users have uninstalled an app that was already on their cell phone because they learned it was collecting personal information that they didn’t wish to share

Taken together, 57% of all app users have either uninstalled an app over concerns about having to share their personal information, or declined to install an app in the first place for similar reasons.
