How Silent VPN protects your traffic
Plain-language explanation — see the Privacy Policy for the legal version.
1. What actually happens when you connect
When you tap Connect, the app opens an encrypted tunnel from your device to one of our VPN servers using the Xray proxy protocol — specifically VLESS over REALITY or TLS, depending on the server. Both are modern transports designed to be indistinguishable from ordinary encrypted web traffic (HTTPS) to anyone observing the connection from outside.
From that point on, every request your device makes — web pages, app traffic, DNS lookups — travels through that encrypted tunnel before reaching the open internet from the server side.
2. Why we can't see your browsing
The encryption is end-to-end between your device and the exit server: the contents of your traffic (which sites you visit, what you send/receive) are encrypted using keys the app and the server negotiate directly. Silent VPN, as a company, does not run man-in-the-middle inspection, does not log destination URLs or DNS queries, and has no separate "analytics" pipeline reading your traffic. What the server sees is exactly what any VPN server has to see to route packets — encrypted bytes and their destination IP — not their decrypted content.
3. What is technically necessary to keep the service running
A VPN server has to know a small amount of operational information to function and to enforce your subscription's data/time limits — this is unavoidable for any VPN, not specific to us:
- Connection timestamps (when a session starts/ends) and total bytes transferred, used only to enforce your plan's data allowance and expiry.
- The server-side IP your device connects from, transiently, the same way any network service sees the IP of an inbound connection.
This is retained only as long as needed for billing/quota purposes, not indefinitely, and is never linked to your real identity — see Data We Collect for the full, itemized breakdown.
4. Open engine, not a black box
The VPN core is XTLS/libXray, an MIT-licensed open-source library wrapping the widely used Xray-core proxy engine. The protocol logic that encrypts your traffic is publicly auditable source code, not a proprietary implementation you have to take our word for.
5. Kill switch
If the VPN tunnel drops unexpectedly, Silent VPN blocks network traffic rather than silently letting your device fall back to your regular, unencrypted connection — so a dropped VPN connection never quietly exposes traffic you thought was protected.
6. No mandatory account
The app doesn't ask for a name, email, or phone number to use. You're identified only by an anonymous, randomly generated ID shown in Settings — enough to match a purchase to a subscription, nothing more.
