Kuaiya security practice: no-logs policy and DNS leak protection
Lead: "We don't keep logs" is a claim almost every accelerator makes, but few stand up to scrutiny. This article focuses on two Kuaiya VPN security practices — its no-logs policy and DNS leak protection — explaining the technical implementation and boundaries.
What the no-logs policy covers
Kuaiya VPN's no-logs policy promises not to record three types of data: browsing history, visited destinations, and real IP addresses. To keep connections alive, the system keeps only temporary session info that is cleared immediately after the session ends, with nothing persisted that could identify a person.

How DNS leak protection works
DNS resolves domain names to IPs. If this query goes to your local ISP's DNS server, it reveals your intent. Kuaiya VPN forces all DNS requests through a private DNS inside the encrypted tunnel, and the client has built-in leak detection that blocks and alerts the moment a request tries to bypass the tunnel.

The kill switch backstop
Even if the tunnel drops, without a backstop traffic falls back to direct and the real IP leaks. Kuaiya VPN's kill switch cuts the network the instant the tunnel drops, until it recovers, reducing traffic outside the encrypted tunnel to zero.
| Mechanism | Protects | Trigger |
|---|---|---|
| No-logs policy | Leaves no traces | Architecture |
| DNS leak protection | Hides destinations | Forced private DNS |
| Kill switch | Prevents IP leak | Auto on tunnel drop |
Real case: a journalist's sensitive work
A journalist doing overseas interviews chose Kuaiya VPN for its no-logs policy and kill switch. He reports that even with unstable local networks, he never saw traffic fall back to direct and expose his identity.
"For interviews, exposing sources is my worst fear. Kuaiya's no-logs and kill switch give me the safety I need." — a media journalist
Data and verification
Kuaiya VPN publishes a DNS leak test guide so users can verify for themselves. In August 2026, 96% of users confirmed no leaks in self-tests, and the third-party audit confirmed the logging policy matches its promise.
| Verification item | Result |
|---|---|
| DNS leak self-test pass rate | 96% |
| Audited logging policy | Matches promise |
| Kill switch response | <1 second |
Conclusion
Privacy is not a slogan but layers of no-logs, DNS protection and kill switch. Kuaiya VPN makes these verifiable defaults. Free VPN download Kuaiya and self-test to see for yourself.
