#17 removed the `setSessionExpiry` and `isVpnRuntimeAlive` MethodChannel handlers from MainActivity, and #18 removed their last callers. The Dart wrappers stayed behind. Both swallow their errors, so a future caller would not fail loudly — it would get a silent no-op from `setSessionExpiry` and a permanent `processAlive: false` from `runtimeState()`, which previously read as "the tunnel is dead". Deleting them keeps that trap out of the codebase. `VpnRuntimeState` goes with them; runtime liveness now arrives through the native status stream, which is generation-scoped. The battery-optimisation methods are untouched and still used by background_reliability.dart.

ReVoltVPN
A free VPN app for Android. Open-source client, transparent infrastructure. Watch an ad, get 2 hours of full-speed traffic — no accounts, no logs, no subscriptions.
How it works
- Watch a short rewarded ad
- Server creates a temporary VLESS session (2 hours / 10 GB)
- Your traffic routes through a single server in Finland at full speed
- When time or data runs out, session ends — watch another ad to continue
- No throttling, no slow lane, no mid-session punishment
No email. No password. No payment. The ad pays for the server.
Protocol
- Transport — VLESS over XHTTP (HTTP/2 multiplexed, path-hidden behind
/revolt) - Obfuscation — Xray Reality spoofs a real website's TLS. To any DPI box, your tunnel looks like a browser visiting that website
- Encryption — TLS 1.3 with borrowed certificate (Reality). No certbot, no domain ownership required
- API — Standard HTTPS to a separate domain. Tunnel destination is IP-pinned — domain compromise is DoS only
Stack
| Layer | Technology |
|---|---|
| App | Flutter (Android) |
| VPN | VLESS + Xray Reality + XHTTP |
| Backend | Python Flask ("Hivemind") — session management, quotas, stats |
| Ads | Google AdMob rewarded, verified server-side |
| Server | Debian, single Hetzner box in Finland |
Limitations
- One server, one location (Finland)
- 2 vCPU / 4 GB RAM — not built for thousands of concurrent users
- Android only
Privacy
Your traffic routes through Finland. We don't log it, inspect it, or sell it. Hivemind tracks only session liveness and byte counters for quota enforcement — no packet contents, no destination IPs, no DNS queries.
