Sendant is a private, encrypted messenger built on a simple promise: your conversations belong to you. Messages are end-to-end encrypted by default, your keys never leave your device, there's no central server quietly logging who you talk to — and no phone number, email, or account required to start.
It feels like the messengers you already know — fast chats, groups, attachments, reactions, and disappearing messages — but the trust model underneath is different.
WHY SENDANT
• End-to-end encrypted by default (X3DH + Double Ratchet). Only you and the people you're talking to can read your messages.
• No phone number, email, or account. Your identity lives in cryptographic keys held on your device, not tied to your SIM.
• Messages that don't get lost. Your message is sealed on your device and held in a store-and-forward mailbox the servers can't read, so it waits and delivers when your contact reconnects.
• Less metadata. We minimize the "who talked to whom, when" trail that centralized apps collect by default.
• Verify the people you trust. Confirm a contact with a QR code or safety number, and get a clear, plain-language warning the moment something changes.
• No ads, no tracking SDKs.
TRUST YOU CAN READ
Security here speaks plain English. Sendant shows "Verified," "End-to-end encrypted," and "Safety number changed" — never cryptographic jargon.
PRIVACY BY DEFAULT
No phone number, email, or account required. Local-first storage on your device. Your keys stay under your control.
Private by default. Calm by design.

• Incoming calls now ring through the iPhone's call screen, like a phone call.
