Or in Other Words

A VPN protects your privacy online by creating a secure "tunnel" between you and your Internet destination.This tunnel is created by first authenticating your client to Your device with a VPN server. The server, which you can run yourself with VPN application installed in your device, then it uses one of several encryption protocols to make sure that everything sent between you and websites and Internet services can't be monitored by trackers. as i said before, It does it by creating an encrypted tunnel, which is like putting a package into a box and then sending it to someone. Nobody can see what it's inside the box until it's opened/decrypted.
