in what ways am I NOT giving SN the ability to spend my money:

 when SN's website is NOT loaded in your browser or your wallet is NOT decrypted or your browser is NOT connected to the internet, SN cannot spend your money.

The encryption key must live somewhere so can't SN decrypt said NWC and spend money that way? Or do I severely misunderstand NWC
