Facebook is giving us a new way to glimpse just how much it knows about us: On Tuesday, the social network made a long-delayed “Off-Facebook Activity” tracker available to its 2 billion members. It shows Facebook and sister apps Instagram and Messenger don’t need a microphone to target you with those eerily specific ads and posts — they’re all up in your business countless other ways.

Even with Facebook closed on my phone, the social network gets notified when I use the Peet’s Coffee app. It knows when I read the website of presidential candidate Pete Buttigieg or view articles from The Atlantic. Facebook knows when I click on my Home Depot shopping cart and when I open the Ring app to answer my video doorbell. It uses all this information from my not-on-Facebook, real-world life to shape the messages I see from businesses and politicians alike.

You can see how Facebook is stalking you, too. The “Off-Facebook Activity” tracker will show you 180 days’ worth of the data Facebook collects about you from the many organizations and advertisers in cahoots with it. This page, buried behind lots of settings menus (here’s a direct link), is the product of a promise CEO Mark Zuckerberg made during the height of the 2018 Cambridge Analytica scandal to provide ways we can “clear the history” in our accounts.
