About Vauchi¶
Privacy-focused updatable contact cards via in-person exchange.
What We're Building¶
Vauchi is a contact card that updates automatically. When you change your phone number, everyone who has your card sees the change — no need to notify them manually.
Unlike traditional contact apps:
- No accounts — Your device is your identity
- No phone number required — Exchange cards in person
- End-to-end encrypted — Only you and your contacts can read your data
- Open source — Verify every claim yourself
Why We Built It¶
Contact information goes stale. You change jobs, move cities, get a new number — and suddenly half your contacts have outdated info. The usual solution is to use a platform (social network, messaging app) as the source of truth, but that means trusting a company with your data.
We believe there's a better way: updatable contact cards that stay private.
