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.

You need a QR code right now. Not in five minutes. Now. This app lets you create one in seconds. Enter any text, link, or contact info. Generate a clean QR code instantly. Save it or share it anywhere. And when you need to scan? It handles both QR codes and barcodes like a pro. Point your camera and the result appears immediately. URLs open. WiFi connects. Product info shows up. No waiting. No retries. Vibration and sound confirm every successful scan. Auto copy to clipboard. One tap to open links. It just works. All common barcode formats are supported. EAN, UPC, Code 128, Code 39, and many more. One more small bonus. Sometimes you're not scanning a code but struggling to read a dark receipt or faded label. There's a simple document brightener mode built in. Not the main show, just a handy extra when you need to see something clearly in poor light. Create. Scan. Share. That's it. Download now and get both tools in one free app. Privacy Policy:https://www.termsfeed.com/live/c6ce2b1a-46f0-4fd9-a63f-36e4eeebfda3
