Unfortunately, we do not support content and payment sharing with multiple devices. You can transfer your data from one device to another, and keep your data on one device only.
Song packs, Singles, Star Pass, and Gems that you bought on one device cannot exist on another device simultaneously. If you really wish to use two devices to play Starri and keep the purchased items on both devices, you are required to buy the same thing twice.
Please read: I would like to switch to my new device to play Starri. How can I transfer data?↗︎
