Facebook, Google, Microsoft, and other tech companies have a ton of our data. We give up a lot of our privacy to use their services. But we don't always know how well that data is protected or which 3rd parties have access to it. Data breaches like Collection #1 or attacks like the T-Mobile hack happen way too frequently. And companies like Facebook have been criticized for uploading user data without permission. What's going on with your data and how can you maintain your privacy online?
