A lot of people use VPNs to limit their digital footprint. Windscribe, TunnelBear, AtlasVPN, and others do a great job masking your IP address or encrypting your traffic. But in most cases, you don't really need a VPN to reduce your footprint on the internet, since most browsers already have built-in privacy features. Besides, using a VPN doesn't really stop companies from tracking you through your browser, accounts, or device habits.
