I recently got an Amazon Fire Stick and downloaded a Kodi Build. I keep seeing things about Virtual Private Networks (VPN) ensuring my privacy. My entire network involves being at home. I don't stream movies on the road or anything like that. My wife and I use our Android Smartphones only for email, text, Facebook and calling. At home I have 4 TV's (3 Smart, I Dumb), w Xbox One's, 2 Xbox 360's, a WII, two Windows 10 PC's, an HP printer all on my Network. I own my own Router a Netgear N750 Wireless Dual Band.

I like to use Kodi for watching movies, but mostly I use the Amazon stuff on the Fire Stick.

Do I need a VPN Service or can I somehow set up my router for the protection provided by a VPN?

After searching data about a VPN, I'm just more confused than ever.

Help! Thanks in advance.
