title: Google Play Promo Codes
body: <p>I want to distribute my app via Google Play but to be visible only to users have my Promo Codes. It's possible in App Store but looks like not possible in Google Play. </p>
  
  <p>Is there any way to achieve this?</p>
  
  <p>Note : I don't want to use Google Play Alpha/Beta tests since I need to provide email address for users. I just want to distribute my app via promo codes (or sth similar) before launching.</p>
  
  <p>Thanks</p>
