Your smartphone’s apps may be tracking your location, contacts and other personal information.

The average American has 32 apps on their phone, but many are not aware of what those apps are tracking behind the scenes.

Adi Kamdar works for the Electronic Frontier Foundation and said apps have access to almost all information on your phone, and you are responsible for restricting that access.

"With some apps it's the developers that have access to this information, and with other apps they actually have agreements with third parties, whether data brokers or advertising companies where they send this information to them." 

Kamdar said you should delete anything you do not use and make it common practice to change your password. Next time you download an app, pay attention to what permissions it is requesting.
