I would not recommend that. Even on Android people have had problems restoring their data after reinstalling the game even though they were signed in with Google/Facebook. There is no way to be sure what save file of your progress Nekki has on their servers so it's better to try the uninstall-reinstall approach only if you can backup the data yourself.
