When VPN is enabled, internet access will be routed to the application. Through this application, you can decide which app should access the Internet and which app shouldn't. There is no actual VPN creation and no information has been sent over to the external servers. All data access will be centralized. This makes you the superuser to allow or deny Internet access to certain apps.
