title: Firebase's Cloud Firestore Free Quota Run Out Permanently Once Exceeded?
body: <p>I have read about the pricing for Firebase's Cloud Firestore usage and in the first screenshot below it says:</p>
  
  <blockquote>
    <p>Quotas are applied daily and reset around midnight Pacific time.</p>
  </blockquote>
  
  <p>While in the second screenshot it says:</p>
  
  <blockquote>
    <p>After you exceed the usage and storage quotas for the free tier,
    you're charged for the database operations you perform</p>
  </blockquote>
  
  <p><strong>My Concerns:</strong></p>
  
  <p>Let's say I build an app using Firebase's Cloud Firestore and at some point the app exceeds the free quota:</p>
  
  <ol>
  <li>Will that free quota be permanently gone (never to be accessed again) after exceeding it for the first time.</li>
  <li>Will I now be automatically charged after exceeding the free quota? (even though I have never signed up for billing)</li>
  </ol>
  
  <p><strong>Or</strong> </p>
  
  <ol>
  <li><p>Since I am using the <strong>free tier quota</strong> and haven't signed up for billing, I'll just be restricted from communicating with the backend until I stop exceeding the free quota limits?</p></li>
  <li><p>Will the free quota still reset at midnight as long as I make sure to stop exceeding the free quota limits?</p></li>
  </ol>
  
  <p>Essentially, I have never signed up for a billing account, I have always had a free Firebase account, <strong>so what precisely happens</strong> when a <strong>free account</strong> user exceeds the free quota provided by Cloud Firestore?</p>

  <p><strong>Additionally:</strong></p>
  
  <p>Is it more feasible to build a social media app (with lots of read and writes to and from the backend), such as when users' make posts in the app, with <strong>Cloud Firestore</strong> or should I use the classic <strong>Real Time Firebase Database</strong>? <strong>(In terms of pricing)</strong></p>
  
  <p><strong>Lastly:</strong></p>
  
  <p>It was stated on Firebase that users can monitor their quotas using App Engine. My concern is, in order to use this, do I have to be using a paid billing account or can a free account user monitor his/her quotas if using the app engine?</p>
