No, your private key need only for sign and view your unspent balance.

We do not send your private keys anywhere and do not store them. Operations with private keys are held in your browser.
But we recommended use one-time addresses where you do not store coins.

First address and second what this?

First address(TO) it will have a Malicious Transaction character, that is, it will be removed from the blockchain and the coins will not be confirmed at this address.
Second address(TO2) to this address, you return your coins when you broadcast the second transaction.
