A simple, fully free-software WireGuard VPN client for Android. It manages tunnel profiles and connects — nothing more.

Create, list, edit and delete WireGuard profiles. Import a configuration by scanning a QR code or opening a .conf file; export a tunnel back to a standard wg-quick .conf (guarded by device authentication — the file contains the private key). Connect/disconnect with a per-tunnel switch (userspace backend, no root). Always-on VPN support: enable it from the shield action in the app (opens the system VPN settings) and Android reconnects your most recently used tunnel automatically — including after a reboot, and with the optional kill-switch. No trackers, no analytics, no ads, no Google Play Services. The only network connection the app makes is your own WireGuard tunnel.
