Califax VPN delivers next-generation privacy with quantum-resistant encryption, a strict zero-log policy, and RAM-only servers around the world. Connect in one tap and reclaim your online privacy. WHY CALIFAX VPN • ZERO-KNOWLEDGE ARCHITECTURE — We can't see your traffic, your browsing history, or your real identity. This is enforced by our technology, not just a policy. Trust the math, not the company. • QUANTUM-RESISTANT ENCRYPTION — Next-generation cryptography designed to resist attacks from both today's adversaries and tomorrow's quantum computers. • RAM-ONLY SERVERS — Our servers run on volatile memory only. When a server reboots, all data is irrecoverably destroyed. Nothing is ever written to disk. • SMART PROTOCOL ENGINE — Our AI auto-select picks the best tunnel for your network in real time, falling back gracefully when networks block standard VPN traffic. • MILITARY-GRADE ENCRYPTION — Industry-standard AES-256 encryption for every connection, every time. • KILL SWITCH — Block all internet traffic instantly if the VPN drops, so your real IP is never exposed. • AUTO-CONNECT — Connect automatically the moment you join an untrusted Wi-Fi network. • LOCATION PRIVACY — Optional on-device location fuzzing protects your real GPS coordinates from leaking to other apps. • GLOBAL SERVER NETWORK — Servers across North America, Europe, Asia, the Middle East, Africa, and Oceania. Pick a region or let the engine pick the fastest one. • APP STORE PRIVACY — We collect the minimum data needed to provide the service. No advertising, no tracking, no third-party analytics. SUBSCRIPTION • Monthly: $9.99/month — auto-renews • Yearly: $59.99/year — save 50%, auto-renews • 7-day free trial for new subscribers • Cancel anytime in Settings → Apple ID → Subscriptions Payment is charged to your Apple ID.
