Minecraft is sold and licensed separately on each platform, and transferring licenses is not possible. For example, if Minecraft was originally bought on a PlayStation®4 and you want to transfer it to the Xbox One or the Nintendo Switch, or you purchased a copy on an iOS device, but instead want to play on an Android device.
Deleted Minecraft applications can be redownloaded using the same store account and device type on which it was purchased. You can visit your device's marketplace, search for Minecraft, and re-download the app for free.
For more information on these policies, please contact your marketplace's support center:
