QuizUp's lax security lets other players see your private data

Also of note is how QuizUp handles access to your contacts. The game allows you to invite your friends to the game via text message, which you need to grant QuizUp access to your contacts to allow. Once this is done, QuizUp sends your contact's emails, in plain text, to their servers, in violation of federal privacy laws.

Last week I downloaded QuizUp on my iPhone and was planning to sign up as soon as I had some free time. Today I deleted the app without signing up.
