Features

Vauchi is designed to be simple, private, and useful. Here's what it can do.


Core Features

Contact Exchange

Exchange contact cards in person via QR code. Both parties must be physically present, preventing spam and impersonation.

Privacy Controls

Control what each contact can see. Show your work email to colleagues, your personal number to friends, and hide your home address from acquaintances.

Multi-Device Sync

Use Vauchi on your phone, tablet, and computer. All devices share the same identity and stay in sync.

Auto Updates

When you update your contact card, everyone who has it sees the change automatically. No more outdated contact information.

Backup & Recovery

Protect your identity with encrypted backups. If you lose access to all devices, social recovery lets trusted contacts help you regain access.

Encryption

Everything is end-to-end encrypted. Your data is unreadable to anyone except you and your contacts — including us.

Design Principles

Every feature in Vauchi is guided by our principles:

  1. Privacy is a right — Encryption by default, no tracking
  2. Trust is earned in person — QR exchange, not account lookup
  3. Quality comes from rigor — Tested, audited crypto
  4. Simplicity serves the user — Do one thing well
  5. Beauty adapts to the user — Customizable appearance
