For Users

A paper business card is a small act of optimism. You hand someone a rectangle of card and quietly hope that, months later, when they finally need you, the ink still means something. Usually it doesn't. By then you've changed job, number, or city, and your carefully chosen typeface is a fossil in a drawer.

Vauchi starts from a different premise. The valuable part of meeting someone is the meeting — the fact that you chose to be in the same room. The data is just the residue. So Vauchi keeps the human bit exactly as it is — you swap details face to face, on purpose — and quietly fixes the part that always rots. When your number changes, theirs updates. No re-sending, no "hi, new phone!" group text, no fossils.

This section is the owner's manual. It is shorter than you fear.

Why this one is different

Most apps want to be the room you live in: a feed to scroll, a follower count to mind, a profile to perform. Vauchi wants to be the handshake, and then get out of the way. There is no feed, no audience, no number going up.

The whole thing rests on one slightly unfashionable idea — that giving someone your real details, in person, because you decided to, is worth more for being scarce, not less. A contact you met is a contact you meant. Everything in the app is built to protect that.
