But free apps often have a privacy cost. When you install an app, you probably never read its terms and conditions. You merely click “Agree.” In the terms and conditions, the app developer typically reveals what data you are voluntarily handing over, such as your online activities, location, contact list, text messages and more. (By the way, none of the apps on my 10 Best lists do this.)
Researchers at Carnegie Mellon University recently analyzed the Google Play store’s top 100 apps operations, terms and conditions. They found these 10 requested the most access to your smartphone or tablet’s hardware:
Backgrounds HD Wallpaper
Talking Tom Virtual Pet
It makes sense that Google Maps needs your location and song-identifying Shazam needs access to your microphone, but why does a virtual pet, dictionary or wallpaper app need anything like that? Both iOS and Android have built-in flashlights, so you don’t even need an app.
While the researchers looked at Android apps, almost all of them have iOS versions. iOS lets you set permissions on a case-by-case basis. Go to Settings>>Privacy and choose the permission, such as camera or GPS. Slide the slider to “Off” to deny a permission.
Unlike iOS, Android doesn’t have per-app permission controls. It was a hidden feature in Android 4.4.2, but Google removed it. No one knows when or if it will be back.
Before you install any Android app, check the app’s page in the Google Play store. Google requires that developers reveal permissions that the app requires.
On an app page, scroll down to the “Additional Information” section and under “Permissions” click “View details.” Google users can turn off GPS and location services. Go to Settings>>Personal>>Location Services and uncheck any checked boxes.
As for apps that collect your contact data, make sure the app needs it for a legitimate reason. For example, communication apps Skype or Google Voice require it.
If you’re wondering about other apps, visit PrivacyGrade, where researchers from Carnegie Mellon examine what permissions an app should need and what it actually requires, and then they assign it a grade.
