Many smartphone apps gather and distribute your important information with relative ease due to the lack of privacy policy. Pandora, a popular music application, which is available in both iPhone and Android  platforms, sends your age, location, gender and phone’s ID to other advertising networks, while Paper Toss, also a popular game, distributes your phone identifier to five advertising companies. Obviously, if you have these three apps simultaneously on your device, your “private” information is widely available on the advertising industry.

Unfortunately, there is nothing users can do to prevent third-party apps from sending their important data, except by removing the apps completely from their devices. When contacted, developers of those apps argued that any data given to third-party firms are not linked someone’s name. They claimed that they only sent age and gender information as volunteered by users.

Nearly half of apps sold today don’t contain any kind of privacy policy as Google and Apple do not require a privacy policy in applications.

The most commonly shared information shared is your device’s unique ID number, for example, on iPhones it is called “UDID” (Unique Device Identifier). On Android platform, establishing a uniform consumer protection policy can be more complicated. If iOS is exclusively used by Apple, Android is being employed by many phone manufacturers including Samsung and Motorola. Android apps are not reviewed by Google and user can download them from many different vendors.  Google only requires apps developers to include a notification about data sources that the app may access, including contact list, memory card, phone’s camera, bookmarks and many others. Users can cancel the download process if they disagree.
