Hubyn is a private messenger and workspace for iPhone and Mac, built around a PIN you own instead of a phone number.
It is not open to the public yet. Tell us who you are — we'll confirm straight away, and write once more when testing opens to people outside the build.

Questions, answered.
Hubyn is in controlled pre-production testing, so these answers say what the product does today and what is still waiting on a gate outside the code.
Frequently asked questions
01Is my PIN a password?
+
No. A Hubyn PIN lets someone request a connection. It does not unlock your account, conversations, calls or workspaces. Your identity is proven by cryptographic keys — not a phone number, carrier or uploaded address book. A claimed PIN is verified against the sender's identity key, so it cannot be spoofed.
02Who can read my messages and files?
+
Only their participants. Messages and files use libsignal — X3DH, the Double Ratchet and PQXDH — never a custom ratchet. Workspace content reaches the service only as ciphertext it cannot merge or interpret. Call media is built with SFrame (RFC 9605) above the transport, keyed per sender per epoch, so the forwarding server relays ciphertext without possessing the keys. That is what the implementation does — production provider activation and physical qualification are still underway, so we describe it as built rather than proven.
03Where does my work live?
+
Messages, files, workspaces and transcripts are stored through encrypted, identity-scoped systems, sealed locally under a device-held key a restored backup does not carry. When admitted devices share a local network, Hubyn can carry that traffic directly and deduplicate it against relayed delivery — carriage only, never identity or membership authority. V1 claims no mesh and no arbitrary nearby connectivity.
04What does Jimmy actually see?
+
Jimmy uses local models on supported Apple hardware and loads only the context you authorize. Jimmy proposes; it never acts on its own. Every summary cites its source, on systems where summarization is available. Web research is off by default, tells you before it runs, shows what will be sent, and names the provider receiving it.
05What happens if I lose my device?
+
Recovery restores your identity, not the lost device. A replacement receives fresh keys, the old device's authority is retired, and important identity changes remain visible. Each linked Mac can be revoked. You keep your Hubyn PIN without the system pretending nothing changed.
06Why are the status words so literal?
+
Because Hubyn tells you what actually happened. Sent is not Delivered. Delivered is not Read. Encrypted is not Verified. Requested is not Applied. Unavailable is not Success. The system never softens a distinction to make a screen look calmer — which is the same reason every capability above carries its real state instead of a checkmark.
Something not working?
Tell us what happened and we'll get back to you. During controlled testing this reaches a person, not a queue.
