Unfortunately, it’s not as simple as just turning on your VPN and disappearing off grid. While VPNs certainly offer better privacy and security, they don’t make you completely anonymous. There are a mindbogglingly number of ways that companies track you across the internet and a VPN isn't capable of blocking all of them. For example, when you sign into a website, your identity is revealed to that website. Or when you log into your Gmail account while using a VPN, Google can now collect cookies based on your browsing.
