StealthOS is a native iOS application that provides a privacy-focused environment with multiple security and privacy features. The application operates entirely on-device without external servers or third-party APIs. The browser component includes anti-fingerprinting capabilities that spoof Canvas, WebGL, Audio, Navigator, Screen, Timezone, Fonts, and Battery APIs. Users can create and manage multiple device profiles with different fingerprint identities. WebRTC protection blocks IP leaks and removes trackers, analytics, and fingerprinting scripts. Security features include AI-powered phishing detection, domain age verification, shared IP detection, and anti-malware protection using on-device CoreML models. The system detects crypto miners, keyloggers, formjacking, data exfiltration attempts, and drive-by downloads. Data protection includes AES-256-GCM encryption for file storage and password management. The password manager supports TOTP 2FA, browser autofill, and field-level encryption. Local peer-to-peer communication uses Curve25519 and AES-256 end-to-end encryption for messaging. Networking features include isolated DNS, Proxy, and Tor settings that only affect StealthOS without impacting device-wide settings. DNS-over-HTTPS support includes Cloudflare, Google, Quad9, and OpenDNS providers. Additional components include an SSH terminal with ANSI/xterm-256color support, a virtual Linux environment with 70+ commands, a code editor with syntax highlighting for 20+ languages, voice notes with transcription and speaker diarization, and an AI assistant with 20+ native tools.
