We warmly welcome you to the Friendly King Community's Candy Crush Saga forum.🤗
In the case of Android and I-Phone, your collected booster & lives is stored in the device memory. This stored booster & lives can not be synced with the server, because the game studio still does not have this process.You will not be able to transfer the boosters to another device, you will lose the complete booster & lives for app uninstalling or crashing. And the boosters & lives are not refundable.
I'm sorry I couldn't help you.😌
