Secure messaging,
end-to-end encrypted.
AlphaMessage is a username-based, end-to-end encrypted messenger. The server can never see your content.
Features
From end-to-end encryption and channels to voice calls and multi-device support — everything AlphaMessage ships.
End-to-end encryption
Every message is encrypted on your device with the Signal Protocol (X3DH + Double Ratchet). The server only relays ciphertext and never sees your content.
Channels (servers)
Discord is blocked in Türkiye, so AlphaMessage ships the same thing: text and voice rooms, categories, roles and permissions, moderation, screen sharing. Channel messages and text rooms are end-to-end encrypted; the audio stream of a voice room is not.
Multi-device
Use one account across several devices. Each device holds its own key pair; messages are encrypted separately for every device.
Voice & video calls
Voice notes, one-to-one and group voice/video calls. In a call, audio and video frames are end-to-end encrypted before they leave your device. (Voice rooms inside a channel are distributed by a server and are not end-to-end encrypted.)
No ads, no tracking
No ads, no analytics, no trackers. We do not sell your data. The server keeps only the minimum metadata needed to route messages.
Deleted on delivery
Encrypted messages are deleted from the server as soon as they are delivered. History lives only on your device, in an encrypted local database.
