What TalX does differently

No account, no number

On first launch the device generates a key pair. That is the entire sign-up. No phone number, no e-mail address, no profile held by a provider – and therefore no record anywhere that could go missing.

Works without the internet

Two devices in range talk to each other directly, over Bluetooth and Wi-Fi Direct. On the same Wi-Fi they find each other via mDNS and deliver over a direct connection – voice and video calls included, with no server involved at all.

Encrypted on the Signal principle

Double Ratchet with a fresh key per message, forward secrecy from the very first message, and a hybrid post-quantum share (ML-KEM-1024) mixed straight into the root key. All of it from vetted libraries – no home-made cipher code.

Transcription and translation stay here

Voice messages are transcribed on the device, texts are translated on the device. A cloud translator would receive the plaintext of every message – which is precisely what end-to-end encryption exists to prevent.

Being honest about it

TalX has not been independently audited

Every review so far has been internal – thorough, documented and covered by regression tests, but internal. An independent external cryptography audit is still outstanding and is tracked as open finding F-07. If you need communication that a life depends on, use Signal. TalX is strong in its niches: offline, on a local network, without a phone number, self-hosted.

Compared with WhatsApp and SignalFactual and deliberately even-handed – including a chapter of its own on where TalX loses.

Goals & roadmapA server cluster instead of a single relay, an external audit, an iOS version and a modular crypto core of our own.
