title: Facebook Log Out required for Unity apps?
body: <p>According to the Facebook policy, article I.6 states:</p>
  
  <blockquote>
    <p>Your website must offer an explicit "Log Out" option that also logs the user out of Facebook.</p>
  </blockquote>
  
  <p><a href="https://developers.facebook.com/policy" rel="nofollow">https://developers.facebook.com/policy</a></p>
  
  <p>And as far as I can tell 'website' also means 'app'.</p>
  
  <p>Also, the login implementation instructions says under "Policies" to include a log out button (<a href="https://developers.facebook.com/docs/facebook-login/checklist#providelogout" rel="nofollow">https://developers.facebook.com/docs/facebook-login/checklist#providelogout</a>)</p>
  
  <blockquote>
    <p>Your app should offer an explicit "Log Out" option (See Platform Policies section I.6). Make sure that the logout button is easy to find and that it functions properly."</p>
  </blockquote>
  
  <p>That said, according to the documentation for the Unity Facebook SDK's FB.Logout function: 
  (<a href="https://developers.facebook.com/docs/unity/reference/current/FB.Logout/" rel="nofollow">https://developers.facebook.com/docs/unity/reference/current/FB.Logout/</a>)</p>
  
  <blockquote>
    <p>You almost certainly should not use this function, which is provided primarily for completeness. Having a logout control inside a game that executes a Facebook-wide logout will violate users' expectations. Instead, allow users to control their logged-in status on Facebook itself.</p>
  </blockquote>
  
  <p>So, is a  Log Out button required? If so, how is it supposed to be implemented without FB.Logout()?</p>
