ShareVPN is a free VPN service developed by Share Hub for Android users. It provides servers for users to connect to, which have been donated by random users and funded by the developer's own pockets.

Privacy and security are taken seriously by ShareVPN, as their servers and payloads configurations are encrypted with OpenSSL to safeguard users' privacy and security.

The service is free for everyone, and the developer requests users to rate their app wholeheartedly. However, there are rules to follow, such as not allowing torrenting on non-torrent servers and prohibiting illegal activities like child pornography, carding, DDOS, hacking, and other illegal activities.

If you need help with the app, you can contact the developer via their email address. Overall, ShareVPN is a decent free VPN service for Android users who prioritize privacy and security.
