Let’s say you’re browsing online,

shopping on different sites.

Slide4

Advertising companies are always there behind the scenes,

Slide5

collecting lots of information about you.

as if they have a tracking device on you at all times.

Slide6

They can see what you’re looking at

and where you are.

Slide7

They follow you across the web, always adding more information to their profile of you.

Slide8

Based on all they know about you, they can change the ads you see,

Slide9

and provide different prices than other users based on your spending

habits.

Slide10

You know who else can see all this stuff?

Insurance companies, hiring managers, creditors…

Really, anyone who’s curious.

Slide11

If you want to stop sharing with people and businesses you don’t know,

but keep using the internet you know & love,

you have to do something about it.
