Your communications and the data on your devices are far from the only sensitive digital records you’re constantly creating. You’re also leaving behind a trail of breadcrumbs on the paths you take around the internet—paths that are all too visible to your internet service provider and the websites you visit, and which can be highly revealing to anyone building a profile of you and your behavior.

“For me, I always say it’s important to remember you’re not ‘going to’ a website,” says Matt Mitchell, founder of CryptoHarlem, a security and privacy training and advocacy nonprofit. “You’re opening a door, and just like if you open your door, people can see you, and they can see behind you.”
