One app.Ten ways to stay private.
Your private OS.In one app.
StealthOS opens a whole desktop inside one app, locked behind your own password. Real windows you can move, resize or make full screen, a dock for your apps, and nothing that ties it to you.
- Real windows and a dock
- Files, Notes, Voice Notes and more
- No account, no sign up, no tracking
Tor built in.Fingerprint masked.
Stealth Browser connects through a Tor client that runs inside the app, opens .onion sites, and hides the details sites use to fingerprint you. Camera and microphone stay blocked unless you allow them.
- Embedded Tor with .onion support
- Anti-fingerprinting device profiles
- Block camera and microphone for websites
Forced to unlock?They get nothing.
Set a second password for the moment someone makes you open the app. Type it instead of your real one and everything in StealthOS is permanently deleted. It looks like a normal unlock, onto a fresh, empty desktop.
- A separate panic password
- Everything permanently deleted
- Looks like a normal unlock
Passwords and 2FA.Sealed.
Logins, cards, Wi-Fi and PGP keys live in an AES-256 encrypted vault, with live two-factor codes next to the accounts they protect and autofill when you sign in.
- AES-256 encrypted on your device
- Live two-factor codes
- Autofill in Stealth Browser
Scams stoppedbefore they load.
Every page you open is checked for phishing and scam patterns, on your phone. Risky pages are stopped with a clear risk score before you type anything into them.
- Phishing and scam detection
- A risk score for every page
- Runs on your device
Real PGP.Opens anywhere.
Create keys, then encrypt, sign and share messages and files with standard OpenPGP. What you send opens in GnuPG, Proton Mail and Thunderbird.

- Standard OpenPGP keys
- Works with GnuPG, Proton Mail, Thunderbird

Save your whole StealthOS system to one encrypted snapshot file. Restore it later and everything comes back, exactly as you left it. Only your passkey opens it.
- Your whole system in one file
- Encrypted with your passkey
- Restore in one step
Phone to phone.No internet.

Straight answers.
What is StealthOS?
StealthOS is a private operating environment for iPhone and iPad. One app gives you a desktop with real windows, a private browser with Tor built in, an encrypted password vault, OpenPGP, encrypted snapshots, offline chat, calls and games, and on-device AI. There is no account and no tracking.
Is StealthOS free?
Yes. The desktop, Stealth Browser with Tor, the password vault, the panic password, PGP, snapshots, Connection Pool chat, calls and games, and the AI tools are free. Premium adds pro tools: Terminal, a Linux shell, the Code Editor, NetMap and extra fingerprint profiles.
Does StealthOS route all of my phone traffic through Tor?
No. StealthOS is not a VPN. Tor and anti-fingerprinting protect what you do in Stealth Browser inside the app. Other apps on your phone are not affected.
What does the panic password do?
You set a second password next to your real one. If you are ever forced to unlock StealthOS, type the panic password instead. Everything in StealthOS is permanently deleted and the app opens to a fresh, empty desktop, so it looks like a normal unlock. The deletion cannot be undone, so keep an encrypted snapshot somewhere safe.
How does Connection Pool work without the internet?
Nearby phones connect directly to each other over Wi-Fi and Bluetooth, with no signal and no server. Up to 8 people can join a nearby pool. For people far apart, you can run your own open-source StealthRelay: up to 16 people can join a pool through it, including friends who join from a web browser with the relay web client. The relay is open source and you host it yourself.
Does StealthOS collect analytics or telemetry?
No. There is no account to create, and the app has no analytics or tracking SDKs. Your passwords, files and browsing data stay on your device.
Privacy you canhand over.
Free on the App Store for iPhone and iPad. No account needed.
