StealthOS: Private Browser

New: real PGP. Encrypt, decrypt and sign messages that open in GnuPG, Proton Mail and Thunderbird. Plus block any website from using your camera or microphone.

Private browser, PGP encryption, password manager, and encrypted vault in one app. No account. No tracking. Nothing leaves your iPhone unless you send it.

StealthOS puts a whole private workspace inside iOS: a browser that resists fingerprinting, real PGP for your messages, AES-256 storage for your files and passwords, built-in Tor, and end-to-end encrypted chat with voice and video.

PGP AND OPENPGP ENCRYPTION Real PGP, not a lookalike. What you write here opens in the tools everyone else uses.

• Encrypt, decrypt, sign and verify with OpenPGP
• Works with GnuPG, GPG, Proton Mail, Thunderbird and Kleopatra
• Ed25519, Curve25519 and RSA keys up to 4096 bit
• Keyring with fingerprint verification, so you know who you are writing to
• Send a public key or an encrypted message as a .asc file by Mail or Messages
• Encrypt files, and sign text so anyone can confirm it came from you
• Spot a PGP block on a web page and open it in one tap

PRIVATE BROWSER

• Anti-fingerprint protection for Canvas, WebGL, Audio, Fonts, Timezone, Screen and Navigator
• Block any website from reaching your camera or microphone
• WebRTC leak blocking
• 50 tabs, session restore, bookmarks, encrypted history and encrypted downloads
• Address bar suggestions computed offline, so nothing you type leaves the device
• DNS-over-HTTPS, proxy support and password autofill

TOR BROWSER BUILT IN

• Tor with .onion support, no second app to install
• Kill Switch if Tor drops

PASSWORD MANAGER AND ENCRYPTED VAULT

• AES-256-GCM storage with Secure Enclave protected keys

• TOTP two-factor codes with QR scanning

ENCRYPTED CHAT, VOICE AND VIDEO

• End-to-end encrypted messaging, voice calls and video calls
• Peer-to-peer nearby, or through a relay when you are apart
• Open-source StealthRelay you can host yourself
• Send the app's traffic out through your own relay instead of your home network
• Pools stay alive while you are offline, so friends keep talking

SAVE AND RESTORE EVERYTHING

• One encrypted file holds your files, passwords, notes, browser data and settings
