Unfortunately if you reinstall your game app, it's likely that you lose your boosters. This is because boosters are saved locally in your device.
You will find more details about safeguarding
your boosters here.
We recommend using your free items as you go so you get the most use out of them but if you lost any purchased boosters, our Player Relations Team will be able to return them to you through here.
