Well that's simple, every device that connects to the internet has an IP address this is a set of numbers that tells other devices how to get hold of you, much like a postal address.
All we do is tell other devices/websites that your IP address is one of ours making them think you're in a different location like a PO Box
We only deal with some of the requests unlike a VPN
So it's as fast as your internet can handle
Yes using a Proxy or VPN service is perfectly legal.
