# 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 (60 min / 4 GB)
|
|
3. Your traffic routes through a single server in Finland
|
|
4. When data runs out, you're throttled to 1.5 Mbps instead of cut off
|
|
5. Session expires — watch another ad or move on
|
|
|
|
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 `www.github.com` TLS. To any DPI box, your tunnel looks like a browser visiting GitHub
|
|
- **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

## 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.
