If you connect your game to either Facebook or a Kingdom account, you're progress will be saved to their server. That means once you reinstall and reconnect the game to either account you'll get your progress back. The only thing to keep in mind is that it's only progress and gold bars that sync, everything else does not as it's only locally stored and will be wiped.
