Asphalt 8.

[Gamer3]

Hello,
Recently I installed A8 on my phone, played for a while, completed stages & stuff. But now I want to uninstall the game to free up some space for another (My phone have only 8 GB Internal Memory).
So, I want to ask that if I uninstall the game & then reinstall it later, then will the progress of the game be restored or not. If not is there any way to safeguard my progress, for eg. via signing in using Google+.
P.S. : My phone is not rooted.
