If I unstall candy crush on my phone, will I lose everything?

Every time I try to play the game candy crush on my phone, it will start loading, then it will go off.

There are some other steps you can take before you delete the game:

To answer your question though, you will lose your boosters if you delete it, but your progress and gold bars will remain as they are saved to your Facebook/Kingdom account.
