title: How can I save some user data locally on my Xamarin Forms app?
body: <p>I have a simple Xamarin Forms app. I've now got a simple POCO object (eg. <code>User</code> instance or an list of the most recent tweets or orders or whatever).</p>
  
  <p>How can I store this object locally to the device? Lets imagine I serialize it as JSON.</p>
  
  <p>Also, how secure is this data? Is it part of Keychains, etc? Auto backed up? </p>
  
  <p>cheers!</p>
