FUSA VPN

Military-grade encryption for your iOS device. FUSA VPN shields your browsing, protects sensitive data on public Wi-Fi, and keeps your online identity private — all with zero-log policy.

Core Features
of Our Apps
Every feature is carefully engineered to deliver a seamless, safe, and high-performance experience on iOS devices.
End-to-End Encryption
All data is encrypted using AES-256 standards, ensuring your personal information and browsing activity remain completely private and inaccessible to third parties.
Zero-Log Architecture
Our VPN operates on a strict no-logging policy. We collect no usage data, connection logs, or timestamps — your activity stays yours alone.
Smart Junk Removal
The Cleaner app uses intelligent scanning algorithms to identify and safely remove temporary files, cache data, and app leftovers without touching important files.
Duplicate Photo Detection
AI-powered image comparison identifies duplicate and near-duplicate photos, helping you reclaim gigabytes of storage with a single tap.
Real-Time Performance Boost
Monitor your device's performance in real time. FUSA Cleaner identifies resource-heavy processes and helps you keep your iPhone running at peak speed.
Public Wi-Fi Protection
Automatically activates VPN protection when connecting to unsecured public networks, keeping your sensitive data safe in cafes, airports, and hotels.
Privacy Dashboard
A clear, intuitive privacy dashboard gives you full visibility and control over your data exposure, app permissions, and security status at a glance.
Seamless iOS Integration
Built entirely with native iOS frameworks, our apps integrate deeply with the Apple ecosystem — Widgets, Siri Shortcuts, and iCloud sync included.
