title: How do I clear out my data on app signout from crashlytics
body: <p>I am using fabric/crashlytics for log reporting. I am usually setting username, email,id etc once a user signs into my app. I was wondering if there is a way I can clear out my user data on app signout. I tried looking for a way /function to clear data on crashlytics but no luck. Any ideas?</p>
  
  <p>Currently I am setting username, email etc on my user profile page once a user signs in:</p>
  
  <pre><code>CrashlyticsCore.getInstance().setUserEmail(it.email)
                          CrashlyticsCore.getInstance().setUserName(it.firstName)
                          CrashlyticsCore.getInstance().setUserIdentifier(it.username)
  </code></pre>
  
  <p>and also once the app is launched I set this in my "application" class :</p>
  
  <pre><code>Fabric.with(this, CrashlyticsCore())
  </code></pre>
  
  <p>I want to keep the crashlytics running for the app but the user specific data cleared out upon logout. do I simply set it to null such that?</p>
  
  <pre><code>CrashlyticsCore.getInstance().setUserIdentifier(null) etc., 
  </code></pre>
  
  <p>or is there some clearuser data param I can use in my logout function? </p>
