It seems their Android app is open source... Maybe the protocol could be reverse engineered? https://github.com/ProtonVPN/android-app https://github.com/ProtonVPN/android-app PS: Tried their free plan in China and it won't connect ("Connection Timeout"). In fact, I had to use another VPN to get past their app's loading screen (guessing it got stuck while doing a request to their server)...
