VPNKill is a network kill switch for macOS. It blocks traffic that would leave your Mac outside your VPN tunnel. This policy describes what data VPNKill handles — which is easy, because it handles almost none.
Nothing. VPNKill has no accounts, no analytics, no telemetry, no crash reporting, no advertising, and no third-party SDKs. We do not collect, store, transmit, sell, or share any personal information or usage data. The app never phones home.
VPNKill uses Apple's NetworkExtension framework to run a content filter on your Mac. The filter decides whether to allow or block each connection using packet and flow metadata only — the network interface it would use and its source and destination addresses. It does not inspect, record, or retain the contents of your traffic. All filtering decisions happen entirely on your device.
During setup you can run an optional leak self-test. It attempts a single outbound TCP connection to a public server (9.9.9.9, Quad9 DNS, port 443) bound to your physical network interface, to confirm the killswitch blocks it. The attempt carries no personal data — a blocked or completed TCP handshake is the entire test — and the result is shown only to you and stored nowhere.
Your preferences (armed state, pause duration, LAN allowance, manual allow-list, notification choices) are stored locally on your Mac using standard macOS mechanisms and never leave it.
vpnkill.com is a static site served by Cloudflare. It sets no cookies and runs no analytics scripts. Cloudflare may process standard technical request data (such as IP addresses) to deliver the site and protect it from abuse, per Cloudflare's privacy policy.
If a future version of VPNKill ever changes any of the above, this policy will be updated before that version ships, with the change described plainly at the top.
