StealthOS: Private Browser

Private browser with Tor, PGP encryption, password manager and encrypted vault in one app. No account, no ads, no tracking. Your data stays encrypted on your iPhone.

StealthOS puts a whole private workspace inside iOS: a browser that resists fingerprinting and warns you about phishing, 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. All of it behind an app lock with Face ID and a recovery key.

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, Brainpool and RSA keys up to 4096 bit
- Keyring with fingerprint verification, so you know who you are writing to
- Share a public key or an encrypted message as a .asc file
- Spot PGP blocks on a web page and open them in one tap
