title: How to get User Data from the App?
body: <p>Is there a way to get data from the user while they use my app on their device (iPhone/iPad). For example, if the app fills a dictionary during the runtime about which avatar is used most of the time and which avatar not, is there a way to transfer that dictionary to me? Do I need a server?</p>
  
  <p>This is my first time thinking about data transfers over the internet. I don't have any idea or any experience on how to do that. Somehow I feel it is impossible for some security reasons. I found the <code>NSURLConnection</code> class, but this seems to be only one way to move data from a server to the app.</p>
  
  <p>Thanks.</p>
