ALWAYS be careful with pasting your private keys into fork recovery services, remember that coinbase has stated they will make a certain number of bitcoin forks available for withdraw soon.
At the very least you should empty your bitcoin wallet with which you are going to use the private key to recover the forked coins first before using a service like this.
