The encrypted messaging app for iPhone
iOS has strong hardware security built in. A well-built encrypted messenger uses it — here is what to look for in an encrypted messaging app for iPhone.
Encryption plus the Secure Enclave
A strong iPhone messenger pairs end-to-end encryption with iOS key storage. PrivaMesh keeps your private keys in the iOS Keychain — device-only, biometric-lockable with Face ID or Touch ID — so keys never sync to a cloud or touch a server.
Encryption uses X3DH, the Double Ratchet and AES-256-GCM, giving forward secrecy: a key that leaks today cannot decrypt yesterday's messages.
No iCloud backup of your messages
iCloud backups can quietly weaken message privacy in some apps. PrivaMesh keeps history on-device and, by design, does not back it up — forward secrecy deletes old keys, so past messages cannot be reconstructed from your seed alone. Your seed restores funds and identity, not chat history.
