 that your data is, imagine a tunnel between your computer and the website that you're visiting. So it's a little tunnel that is private, and nobody can peer into that tunnel and see what you're doing. So the reason I would recommend a VPN is if you want to access things that you can't typically access in the place you are. So for instance, when I was in China, I couldn't access various social media networks, so I used a VPN to get around that.
