I lost too much data, I don’t know why. I only use VPN to play muonline. And I don’t have full VPN.
Please visit ‘Account → Edit profile’ menu to enable the Connection Log feature to see where your traffics were used. You can find it at Sign In - MUDFISH: Acceleration As a Service link.
At this moment I don’t know why because as default we’re not doing any kind of logging to trace your traffics for privacy protection. So after enabling it, you can see connection logs at ‘Status → Access Log’.
