If there's any free product or app, you are the product.

They are using your data and selling it in some way, shape or form or selling you ads.

Like you are literally the product of anything that's free.

So that's one thing.

Free Wi-Fi, especially, there's different types of free Wi-Fi, right?

There's like free Wi-Fi in airports where you connect to the free Starbucks Wi-Fi or there's free Wi-Fi in airplanes.

So we're going to go through a few different ones.

Okay, please.

So I want to just let you kind of visualize how Wi-Fi works, right?

Okay.

You're connected and let's say you go on Facebook and you send a message to your friend.

That message is literally like flying through cyberspace.

Just imagine your own little tunnel.

It's flying through the tunnel to your friend, right?

The issue is when you're on open free Wi-Fi, it's usually unencrypted, which means that anyone can go in and out of that tunnel and see what you're doing if they want to, if they know how to.

So every time you do any data, like you do anything online-

Well, the good thing is, you're not an idiot.

You're not an idiot.

The good thing is most of the U.S.

websites now are secure.
