If you are worried about the leakage of the ETH private key, you can create a new wallet that is only used for cpc transactions, and then transfer the cpc assets on ETH to this new wallet before "token swap"😀  
 
@cpchain_io How does the token swap in the app work? The app asks for my private key of my ETH-wallet. No way this is serious.
