Dual Screen Sync vs SecureFox

"Welcome to Dual Screen Sync! Stream with ease and enjoy a bigger, better experience on your phone."

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.
