If you're looking for how to transfer your Minecraft worlds between devices, please go to Transfer Minecraft Worlds to Another Device.
We're often asked if players can download Minecraft for mobile for free after purchasing it on a device using a different app store. Unfortunately, this is not possible. For example, if you made your initial purchase on an Android device and then want to play Minecraft on an iOS device, you must purchase it again through your iOS app store.
Apple's App Store, Google Play, and Amazon Appstore each sell their apps separately and do not coordinate sales with competing companies. Unfortunately, it is not possible to download a previously purchased app, including Minecraft, to a device that uses a different online marketplace.
If you've deleted Minecraft and want to download it again using the same app store account and device type where you first purchased it, you can visit your device's app store, search for Minecraft, and download the app again for free.
For more information on these policies, please contact your app store's support center:
