Whether sending emails or shopping for a new car, we all leave a trail of data, or a digital footprint, every time we go online. And while we create a lot of that data, a lot more is created without us even knowing. It can be hard to know how much personal information is floating around the web—and even harder to know how it is being used. It can feel overwhelming, but understanding your digital footprint can increase your control of, and who has access to, your data!
