What Google knows about you
For all the many controversies around Facebook's mishandling of personal data, Google actually knows way more about most of us. It likely knows everything you've ever typed into your browser’s search bar and every YouTube video you’ve ever watched. But that's just the beginning. It may also know where you've been, what you've bought and who you communicate with. A 2018 study by Vanderbilt University's Douglas Schmidt found that Google and Chrome are sending plenty of data to Google even without any user action, including location data (assuming a user hasn't chosen not to share such information). And nearly half the data came from people's interaction with Google's services for advertisers, as opposed to consumers directly choosing to use a Google service. In addition to everything Google collects via its services, Google search aims to be a repository for all the world's information. That means there's a mountain of information accessible on Google because someone, somewhere in the world has put it online.
