Privacy without
compromise.
StealthOS is a private browser, Tor, password manager, encrypted vault, secure notes, on-device AI, and end-to-end voice & video calls · in one iPhone app. No accounts. No tracking.
Twelve privacy tools.
One private app.
StealthOS replaces the bag of single-purpose privacy apps you'd normally cobble together. Each module is built to work standalone · and to make the next one stronger.

A new device,
every visit.
Trackers stitch your identity together using Canvas, WebGL, Audio, Fonts, Timezone, Screen, and Navigator signals. StealthOS spoofs them with realistic, consistent profiles · so the picture they get isn't yours.
- Spoof Canvas, WebGL, Audio, Fonts, Timezone, Screen, Navigator
- Multiple device profiles you can switch on demand
- Premium unlocks up to 10 fingerprint profiles
- WebRTC IP leak blocking always on
Your sensitive stuff,
sealed by your phone.
Files, photos, downloads, notes, and private documents in one workspace · encrypted with AES-256-GCM and unlocked through Secure Enclave-protected keys. The vault belongs to your device alone.
- AES-256-GCM at rest with keys in the Secure Enclave
- File manager for documents, photos, downloads, notes, and private files
- Generate and securely store PGP key pairs
- Face ID / Touch ID unlock · no cloud sync, no key escrow
One vault for every login,
autofilled in-app.
A built-in password manager with autofill in the StealthOS browser, a strong-password generator, real-time strength scoring, and TOTP for 2FA. Scan the QR code or paste the secret · it's yours from then on.
- Autofill across StealthOS Browser and Tor
- Password generator with length, symbol, and pattern controls
- TOTP (2FA) with QR scanning, organized by category
- Field-level encryption and Face ID gating on every reveal
Call without a number.
End-to-end encrypted.
Voice and video calls run over Connection Pool · local peer-to-peer when you're nearby, or via your StealthRelay when you're not. Hardware-accelerated H.264, ChaCha20-Poly1305 encryption, no phone number required.
- End-to-end encrypted voice and video calls
- Local P2P over WiFi/Bluetooth, or via your own relay
- 1-on-1 and group calls inside any pool
- No phone number, no SIM, no contact-list upload
One pool.
Everything you do together.
Pools are the social layer of StealthOS · chat, voice, video, multiplayer games, and relay tunneling, all over a single end-to-end encrypted connection. Pools stay alive when the host goes offline, so friends keep talking and playing without waiting for you to come back.
- End-to-end encrypted messaging in every pool
- Pools stay alive while the host is offline · reconnect with the same key
- Open-source StealthRelay support for self-hosted private relay
- Local peer-to-peer or remote relay · same UI, same encryption
Exit at your relay's IP,
not your home network.
Route the app's browser and built-in network requests through your self-hosted StealthRelay. Destinations see the relay's IP, not yours · and the relay only sees ciphertext, because TLS to the destination stays end-to-end.
- Browser & app traffic exits at your relay; TLS stays end-to-end
- Affects only StealthOS app traffic · other apps are untouched
- Per-pool host approval decides who else can use it as an exit
- Off by default · automatic kill switch if the relay refuses traffic
Take your whole system
with you.
Save everything StealthOS holds · files, passwords, notes, browser history, settings · into one encrypted file, then restore it whenever you want. Even after a factory reset, or on a brand new install. It's encrypted with a passkey only you know, so nothing from the old device is needed to open it.
- One file holds your vault, passwords, notes, browser data and settings
- Encrypted with your passkey alone · AES-256-GCM, tamper-evident
- Keep it in Files, iCloud Drive, or move it to a computer · we keep no copy
- Restoring verifies the whole file before it replaces anything
There is no recovery without the passkey · not by you, not by us, not by anyone.
Threats caught
before you load them.
On-device AI flags phishing pages, scam patterns, and suspicious domains the moment a link is tapped · not after your credentials are gone. Domain intelligence, content blocking, and a duress password give you a stack of safety nets, all running locally.
- AI phishing detection for fake login pages and scam sites
- Domain intelligence for newly-registered, shared-IP, and impersonating domains
- Content blocking for ads, trackers, and fingerprinting scripts
- Duress password: emergency wipe with a single login
An assistant that
stays on your device.
