It talks to the same backend as the bot, so the subscription state matches wherever the user opens it.
One Kotlin Multiplatform codebase — Android, iOS and Windows, interface in Compose.
Two VPN engines in Go live inside: sing-box with VLESS Reality, which I wired into the client, and olcRTC — a censorship-resistant engine no other app on iPhone carries.
The system tunnel differs per platform: VpnService, Network Extension, wintun.
On iOS the extension gets 50 MB of memory, and that decides half of what happens inside the core.
On top of it, a censorship-resistant transport of my own: traffic rides inside an ordinary cloud document editor and looks like document work from the outside.
