Opera today announced a new Android app that promises to cut your smartphone data costs by up to 50 percent. Unlike Opera Mini, which only compressed data from the browser, Opera Max compresses Internet data across apps, browsers, videos and most of the other Internet data transfer you do on the phone. With Opera Max, all your non-encrypted data transfer is compressed and rerouted from Opera’s VPN. The company promises that it only stores the data you use and how much you saved, to quench privacy worries. The app is currently only available to users in the US and Europe, who pre-register for it here. It is currently being rolled out in batches in order to ensure their servers don’t get overwhelmed.
