@cici0710 Hi and welcome,
If you mean your boosters they are stored on the device itself, so if your device or game crashes, you uninstall or even change device. Your boosters are lost or not transferable.
If you had any unused purchased boosters you can contact customer support and they should help you with these , If they were free boosters then they may help but it would be a good will gesture
Thank you
