    Your browser, VPN, or search engine doesn't keep you private online..your device does.
    A VPN just masks your IP address, it doesnt hide your device.
    A virtual private browser is replacing the VPN because it allows a person to surf the Web using a server in the cloud. The server interacts with every site, never your device so you are always anonymous and free of viruses.

    approximate location - if you call 10 miles approximate
    OS and browser version - that's not too hard
    basic info about your CPU and GPU - VERY basic, got just the manufacturer right
    download speed - not even close
    websites you’re logged into - ditto
