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!
Bochur's answer is correct. By way of additional information in your Play Store → Account → Order History , these apps will be shown as 0 price payment apps as the screenshot below shows - all these apps (barring third) were bought free (discounted) and I can install them again on any device (of course with the same account)
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.
- 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.
