Can I delete an app I got on sale? I recently downloaded an app for free from Google play store. It usually costs $0.99, but is now free.
If I were to delete it, will google remember that I purchased it, even though I paid nothing? Can I delete it now, and install it later without purchasing it?
Thanks in advance!
From play store support:


  You can use apps you bought on Google Play on any Android device
  without paying again. However, each device must have the same Google
  Account on it.
  
  You can:
  
  
  Reinstall an app you bought but deleted
  Install an app on more than one Android device. 
  Install an app on a new Android device. 
  


Even though the app you downloaded was free now, being that usually it is a paid app, Google will count it as if you paid $0.00 and therefore it's counted as if you bought it. And as quoted above, purchased apps can be reinstalled later.
