Happ is a mobile application designed to simplify the use of proxy and VPN servers on Android devices. With its user-friendly interface, it offers essential features such as proxy configuration based on user-defined rules, support for multiple protocols, and options for hidden and encrypted subscriptions. The app supports various protocols including VLESS, VMess, Trojan, Shadowsocks, and Socks, enabling users to customize their network experience based on their needs.

One of the key advantages of Happ is its commitment to user privacy; it does not collect any data, ensuring that all information remains on the user's device. However, it is important to note that Happ does not provide VPN services for purchase, and users must obtain or set up their own servers. Additionally, users are advised to adhere to the relevant laws in their jurisdiction while using this application.
