Share a line, not your life.
A private, end-to-end encrypted vault for the people in your life. Relay Lines you hand out instead of your number. And the Exchange — a tap that shares exactly as much as you choose, never more. The black book, engineered as a privacy product.

What is a private line?
A private line is a relay phone number you hand out instead of your own — calls and texts pass through to your phone while your real number stays hidden. Burn it and it goes quiet in both directions. Graduate it and one tap reveals your real number.
The burner number alternative built for trust — paired with an encrypted contact vault that does what a personal CRM only gestures at: it remembers people, privately.
Log a person in five seconds.
At the bar door, one voice note: "met at Lina's party, climber, knows Dev from work, no cilantro — dinner idea, that Thai place." The vault structures it into a person — where you met, the thread, the moments, the circles they run in.
Then it works while you live. The next-touch dispatcher, personal edition: "Maya's gallery opening is Friday — you said you'd go." Memory that holds, without you holding it.
The contacts app is where context goes to die — "Mike Hinge?", "Sarah conference?", fused to a number you can never take back. This is the replacement.
Two phones tap. You choose the card.
Each side picks a disclosure card in the moment — explicit, never inferred. They get a beautiful contact card. You get a vault entry with time and place attached. The physical Vyan card works here too: one piece of hardware, both markets.
Receipts, not promises.

Is Vyan Personal really end-to-end encrypted?
Yes. The vault is encrypted on your device and stored as ciphertext, with keys held by you. We cannot read it, sell it, or be subpoenaed into a gossip file. The architecture is the privacy policy.
What happens when I burn a line?
The line goes quiet in both directions. No bounce, no notification to the other party — it simply becomes unreachable, like any number that changes. The thread archives in your vault, and your real number was never exposed.
Can I move from a burner app?
Yes. Provision a Line per context, hand it out instead of your number, and log the people worth keeping into the vault. Unlike a burner app, a line here has two endings — burn it, or graduate it to your real number when trust matures.
Remember everyone worth remembering.
Open the vault, provision your first Line, and hand out a number you can take back. The free tier is the real product — Black is the rest of it.
Share a line, not your life. Burn it if you need to. Remember everyone worth remembering.
