Vauchi Documentation

Contacts that never go stale.

Swap details once, in person — and they keep themselves current, forever. New number, new job, new city: the people who matter just know, without you ever having to send another "my number changed" text.

What is Vauchi?

Vauchi is a living contact card you exchange face to face, in a single moment — a kind of digital handshake. From then on, whenever your details change, everyone who holds your card sees the update automatically. No feeds, no accounts, no company sitting in the middle of your relationships.

The relationship is yours and theirs. No one else is in the room.

Meet once, stay in touch — exchange in person; it keeps itself current forever
No sign-up, no phone number — your device is your identity
Yours alone — end-to-end encrypted, so only you and your contacts can ever read it
Open source — verify every claim yourself
