title: What are packaged app in context of chrome app development?
body: <p>I am new to chrome app development and I am trying to build a simple Chrome App which will have a database. I will be storing the data locally on the system. </p>
  
  <p>While going through the <a href="https://developer.chrome.com/apps/offline_apps" rel="nofollow">documentation</a> in the <em>Saving data locally</em> section, there's a note which is as follows:</p>
  
  <blockquote>
    <p>Note: Packaged apps cannot use Web SQL Database or localStorage. The WebSQL specification has been deprecated for awhile now, and localStorage handles data synchronously (which means it can be slow). The Storage API handles data asynchronously.</p>
  </blockquote>
  
  <p>So I am confused here, what is exactly a packaged app? And what is the other type of app where there are no restrictions on storing data?</p>
