No phone number. No contact-book upload. No analytics. Just end-to-end encrypted chat, calls, stories, and bots — built on Curve25519 + AES‑256‑GCM with per-message forward secrecy.
See how it works Try it inside Matrix VaultEverything modern messengers do — minus the metadata harvesting.
Curve25519 + HKDF + AES‑256‑GCM, with an ephemeral key per message for forward secrecy. The server routes ciphertext only.
WebRTC peer-to-peer where possible, encrypted TURN relay otherwise. 1:1 and group calls, with optional in-call assistant.
Share with the people you choose, for the duration you choose — 1 hour, 24 hours, 3 days, 7 days. Encrypted in transit, encrypted at rest.
Reminders, weather, currency, translation, dictionary, email bridges — each is a separate end-to-end-encrypted peer, self-hosted on our infrastructure.
Your handle is a globally unique @username. Your identity is a Curve25519 keypair generated on your device. No SIM swap risk, no leak from contact-book uploads.
12-digit per-contact safety numbers verify you're talking to who you think you are. TOFU on first add, alerts if a key ever rotates.
We route ciphertext envelopes. We cannot decrypt your messages, calls, stories, or files. Auditable on the network.
Pairwise encryption fanout, Signal-style. The server never sees plaintext group membership.
Plain-English privacy policy enumerates every byte of metadata we touch. Nothing else.
No AWS, no Twilio, no third-party messaging vendor. Our servers are dedicated hardware in Germany.
YoMatrix Messenger ships today as part of the Matrix Vault iOS app — the encrypted vault + browser + messenger bundle. A dedicated YoMatrix standalone app is in the works.
