Private Browser with Built-in Tor
A privacy-first browser with anti-fingerprinting protections across Canvas, WebGL, Audio, Fonts, Timezone, Screen, and Navigator. WebRTC leak blocking is always on. Up to 50 tabs with session restore, encrypted history, encrypted downloads, DNS-over-HTTPS, proxy support, and password autofill. Built-in Tor with .onion support, on-demand new circuits, and a kill switch — no second app to install.
Encrypted Vault, Password Manager, TOTP, and PGP
Files, photos, downloads, notes, and private documents in one workspace, encrypted with AES-256-GCM and unlocked through Secure Enclave protected keys. Built-in password manager with autofill, generator, strength scoring, TOTP 2FA with QR scanning, and Curve25519 PGP key generation.
End-to-End Encrypted Voice and Video Calls
Call over Connection Pool with end-to-end encryption (Curve25519 + AES-256-GCM or ChaCha20-Poly1305). Local peer-to-peer over WiFi or Bluetooth, or remote via your own self-hosted StealthRelay. Hardware-accelerated H.264 video. No phone number required.
StealthRelay and Relay Exit
Open-source StealthRelay (Rust, zero-knowledge WebSocket relay with Noise NK + ChaCha20-Poly1305) lets you self-host a private relay. Relay Exit routes the StealthOS browser and built-in network requests through your relay so destinations see the relay's IP, not yours. TLS to destinations stays end-to-end. Per-pool host approval keeps you in control.
On-Device AI Assistant and Threat Shield
The AI assistant runs through Apple Intelligence (iOS 26+) with profiles for writing, coding, tutoring, planning, research, and analysis — including voice mode with interruption support. Threat Shield uses on-device AI for phishing detection, domain intelligence (newly registered, shared IP, impersonating domains), content blocking for ads/trackers/fingerprinting scripts, and a duress password for emergency wipe.
Notes, Virtual Desktop, Games, and Premium Workstation
Notes with on-device transcription, multi-speaker detection, AI summaries, reminders, and inline checklists. A windowed virtual desktop with movable windows, folders, themes, and a master password lock houses 15+ built-in apps. Nine multiplayer games (Chess, Ludo, Connect Four, Chain Reaction, Memory Rush, Word Guess, and more) run end-to-end encrypted over your pool. Premium unlocks 10 device fingerprint profiles, SSH terminal, Linux shell, code editor, and NetMap.
