I always wonder who created this website and how does it work because you send some money from an adress to another and a website can see that and gives confirmation i mean how!? It is like escrow? I send btc it goes to blockchain after that to receiver's adress?
And if someone hacks that website all btcs will be gone?

I use it. It is a great wallet. Just use a very strong password and don't lose the password because if you do then your coins are lost since the web site never gets your password - all crypto takes place on your own computer.
Oh, and be sure to back up your wallet data in case the site get hacked, goes down, etc. Then you can just import it into another wallet program.
