# ReVoltVPN A free VPN app for Android. Open-source client, transparent infrastructure. Watch an ad, get 60 minutes of full-speed traffic — no accounts, no logs, no subscriptions. --- ## How it works 1. Watch a short rewarded ad 2. Server creates a temporary VLESS session (2 hours / 10 GB) 3. Your traffic routes through a single server in Finland at full speed 4. When time or data runs out, session ends — watch another ad to continue 5. 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 `some 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.
