SecureFox: Post-Quantum VPN

SecureFox is the first consumer VPN to ship NIST-standardized post-quantum cryptography (ML-KEM-768, FIPS 203) alongside an advanced anti-censorship transport. We build our own Go networking core in-house — we do not repackage a generic, off-the-shelf VPN stack.

WHAT MAKES SECUREFOX DIFFERENT

• Post-quantum key exchange. Hybrid X25519 + ML-KEM-768 (FIPS 203, NIST-standardized) keeps your sessions safe even against a future quantum attacker. Toggle in Settings → Tunnel.
• Stealth anti-censorship transport. A TLS-1.3-mimicking obfuscation layer that makes the tunnel look like ordinary HTTPS, so it keeps working on restrictive networks where standard VPN protocols are blocked.
• Custom networking framework. We compile our own gomobile binding around our Go core + lwIP TCP/IP stack — not a third-party SDK, not a template.
• WireGuard option. A second protocol option for the rawest speed when stealth isn't needed. Switch in Settings → Tunnel → Protocol.

A SERVER NETWORK THAT MATTERS

• Locations across Asia, Europe, and the Americas, with live device-to-server ping next to each city.
• Recommended-server scoring weights ping AND current load — a fast-but-saturated node never beats a slightly slower one with capacity to spare.
• Auto-reconnect after sleep, network change, or OS pause.

PRIVACY-FIRST DESIGN

• No-logs policy. We do not record browsing history, DNS queries, or IP addresses.
• Genuine kill switch — if the tunnel drops, iOS blocks all traffic until it returns. Your real IP never leaks.
• Passwordless sign-in by email link. Sign in with Apple supported. We never ask for your phone number.
• All app data lives in Secure Enclave-backed keychain.
• Payments handled exclusively by Apple — we never see your card.

SUBSCRIPTIONS

• FREE — unlimited use of our entry-tier locations, no time limit, no ads.
• PRO — every server location, more concurrent devices, priority routing.
• PREMIUM — everything in PRO plus streaming-optimized exit nodes and dedicated capacity.

Auto-renewing subscriptions are billed through your Apple ID. Cancel anytime in Settings → Apple ID → Subscriptions; cancellation takes effect at the end of the current period.
