Private messaging without a phone number, email, or company-run account server. PrivaMesh is an end-to-end encrypted messenger for iPhone, built for conversations that should never become someone else’s data. Your identity, contacts, encryption keys, and chat history stay on your device. NO PHONE NUMBER OR EMAIL Create a private identity without linking a SIM, email address, or contact list. Friends find you by nickname, and your address book is never uploaded. NO COMPANY-RUN MESSAGE SERVER PrivaMesh does not operate an account server or message database. Encrypted messages travel through a public, decentralized transport and can be read only on the intended recipient’s device. END-TO-END ENCRYPTION Every message is encrypted before it leaves your iPhone. X3DH establishes secure sessions, the Double Ratchet generates a fresh key for every message, and AES-256-GCM protects content against reading or tampering. Forward secrecy helps protect earlier messages even if a key is compromised later. METADATA PROTECTION One-time delivery addresses, cover traffic, and fixed-size padding are designed to reduce exposure of who you contact, when you message, and how much you send. There are no ads, trackers, or in-app analytics. YOUR DEVICE, YOUR KEYS Encryption keys are stored in the iOS Keychain and protected with Face ID or Touch ID. Your recovery phrase can restore your identity on another device. Chat history intentionally stays local and is not restored. PRIVATE MESSAGING THAT FEELS FAMILIAR • Private one-to-one conversations • Nickname discovery without phone numbers • Disappearing messages • Search, message details, block, and report controls • A private visual view of your contacts • No contact-list upload OPEN SOURCE BY DESIGN PrivaMesh’s source code and protocol are public for inspection. Privacy should be verifiable in the architecture, not dependent on a company promise. Install PrivaMesh and keep your conversations private by design.
