Thunder VPN is a free app that provides lightning-fast VPN service. With just one click, users can access the internet securely and anonymously without any configuration. Thunder VPN encrypts the internet connection, making it more secure than a typical proxy, especially when using public free Wi-Fi. The app has a global VPN network that includes America, Europe, and Asia, and it is expanding to more countries soon. Most servers are free to use, and users can change servers as many times as they want.<br/><br/>Thunder VPN is a great choice for privacy as it has almost the fewest permissions required and the smallest package size compared to other similar apps. This means that less sensitive information is collected, and there are fewer uncontrollable risks from third-party code. The app has a strict no-logging policy, a well-designed UI with few ads, and no usage or time limit. It also does not require registration or configuration and has no additional permissions required. The app is tiny in size but has high performance.<br/><br/>A virtual private network (VPN) extends a private network across a public network, allowing users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. VPNs are used to secure transactions, circumvent geo-restrictions and censorship, or to connect to proxy servers for the purpose of protecting personal identity and location. However, some internet sites block access to known VPN technology to prevent the circumvention of their geo-restrictions.<br/><br/>VPNs cannot make online connections completely anonymous, but they can usually increase privacy and security. To prevent disclosure of private information, VPNs typically allow only authenticated remote access using tunneling protocols and encryption techniques. Mobile VPNs are used in settings where an endpoint of the VPN is not fixed to a single IP address, but instead roams across various networks such as data networks from cellular carriers or between multiple Wi-Fi access points. Mobile VPNs have been widely used in public safety, where they give law enforcement officers access to mission-critical applications while they travel between different subnets of a mobile network. <br/><br/>In summary, Thunder VPN is a free app that provides lightning-fast VPN service with a global VPN network.
