If you are not familiar with VPN, the service allows you to create a personal connection to a remote server that will communicate with the websites you are visiting. Instead of sending and receiving information over a public network where they could potentially be captured by a malicious participant, all of these exchanges are processed by the server. With an encrypted connection between the phone and the VPN server, your data is undetected for anyone trying to spy on your actions online.
Opera's built-in VPN uses 256-bit encryption for data protection. It also blurred the user's true location by connecting to servers located around the world. Until the company has specified what will be available for VPN sites, the beta allows users to choose servers in America, Europe or Asia, or use a setting to automatically select the best available connection. Opera also promises that it will not store user activity logs so it will not store data in a way that can allow someone to identify a person based on their online activity.
