(NBC News) - Just how much information are you giving away each time you use your smart phone?
Revelations about government spy tactics reveal it may be much more than you realize, and now a growing number of companies are offering smartphone applications and devices that will help users take their privacy back.
"I think it's impossible to be 100 percent secure," said security consultant Ashkan Soltani.
To demonstrate, Soltani intercepted NBC reporter Danielle Leigh's phone activity. Applications loaded on her phone sent out her location, age and even shopping habits.
Fortunately, new applications like Silent Text, Silent Phone, Red Phone, Text Secure, Safe Plug and Secret help users interact anonymously.
"It's about being in control of your presence," said Silent Circle's Toby Weir-Jones.
Silent Circle's Silent Phone lets users make encrypted, near record-less calls and video chats. Silent Text does the same for messaging.
Silent Circle will also unveil the Blackphone, an anti-surveillance smartphone.
"They are much more difficult to track," Weir-Jones said.
But security experts say even these phones won't block the NSA, meaning the only way to go completely off the grid is to power down all those devices.
