Siri - are you storing my questions?

(CNN) - What you don't know about Apple iPhone's interactive voice, Siri, could hurt you. Wired magazine reports Siri and other data collecting apps are putting information at risk.

The software license agreement for Apple iPhone says that when you use Siri or Dictation, the things you say will be recorded and sent to Apple and converted into text.

Siri also collects other information - like names in your address book and sensitive user data.
The objective? To help Siri do a better job.

But IBM's Chief Information Officer Jeanette Horan is concerned. In an article in MIT's Technology Review, she says the company has banned some apps on personal smart phones - including Siri - for fear sensitive company information could be leaked.

Other banned apps include public file-transfer services like Dropbox and Apple's iCloud.
