Sky is a fast, secure, and free VPN proxy. It allows you to browse the Internet securely and anonymously. It can be used on public Wi-Fi hotspots, cellular data networks, and even on enterprise Wi-Fi.

With a VPN, your connection speed is much higher than with a regular proxy. 

Sky also allows you to watch videos and stream online content. When you use this VPN proxy, your internet activities are completely anonymous. As it does not keep a log of your activity, it means you cannot be tracked by anybody.

You can also connect to a server in a particular country if you need to. This VPN proxy service is completely free, with no in-app purchases.
