title: How is my data secure with firebase?
body: <p>I have been looking at the demos of <a href="https://www.firebase.com" rel="noreferrer"><strong>Firebase</strong></a> and i am amazed at the functionality and flexibility to store data online. Also looked at the AngularJS Projects tutorial on its <a href="http://angularjs.org/" rel="noreferrer">homepage</a>, with Firebase as the backend.</p>
  
  <p>However, before starting to use it in my web application, i have few questions like:</p>
  
  <ol>
  <li>Where exactly is all my data stored?</li>
  <li>What if my data gets lost in the future due to hardware failure or any other issue?</li>
  <li>Will it be safe to rely on Firebase, for the security of my app data from hackers?</li>
  <li>What if Firebase asks payment in the future for storing or retrieving my app data?</li>
  <li>Is Firebase suitable for storing large data sets, something like 100 MB per user (not just chat data) ?</li>
  </ol>
  
  <p>Can someone help me to clarify these questions?</p>
