Tiashue

There is no sign out button in the game, and deleting the app will not remove your account, your account is tied to your device. In order to remove an account from a device you need to send an in game help message from the device you want unlinked (menu -> extras -> help -> new chat). The message should include what you wish to do, along with the type of device (i.e. iPhone 6+) you want the account unlinked from.
