Opera Max started out as a VPN capable of reducing data usage, as well as blocking apps from accessing the internet. Now Opera is rolling out a new feature to Max, called 'privacy mode,' that aims to make your device even more secure online.
Privacy mode is based on the S Secure feature Opera created for Samsung for the Galaxy J5 Prime and J7 Prime, which filtered ad trackers and other privacy risks. Opera Max takes it a step further by showing information per app, so you can see what applications on your device are potentially dangerous. Opera uses the EasyPrivacy filter list, a massive database of tracking services, to make this possible.
And of course, since Opera Max is a VPN, it's great for use on public WiFi networks where user data can easily be intercepted. This is very similar to Google's WiFi Assistant, but Opera Max works on any network and shows detailed information about each app.
