Does using Mudfish VPN consume data even when not playing the game itself?

Hi! I am planning to buy Credits in Mudfish to be used in Pay per Traffic, but I am confused on how it works. I would like to mainly use this in Hunt: Showdown and some other games that I may find myself having a high ping. Will the data also be consumed by my browser while I am playing? Thank you!

Unfortunately sometimes it could happen. For details, please check the following documents:
