Prove your Aadhaar.
Show nothing.

Your Aadhaar never leaves this device. Your browser builds a proof that answers one question, and nothing but that question.

How it works

  1. UIDAI already signed your Aadhaar

    Your e-Aadhaar carries a Secure QR: your full record, signed by UIDAI. It lives on your device.

  2. The old way hands all of it over

    Checking that signature needs the whole record, so every service that checks it keeps every field.

  3. Shunya proves instead of showing

    Your browser builds a zero-knowledge proof that the signature is genuine and answers one question. Nothing else leaves this device.

Getting your e-Aadhaar

Why this exists

Aadhaar data keeps leaking, and not from UIDAI's vault: every service that checks an Aadhaar the old way keeps a copy, and copies leak. Each incident below is documented and linked:

A proof changes the arithmetic. It answers one question, holds nothing else, and the service never gets a copy of your card. What is never collected can never leak.

Your zero-knowledge proof

This is the entire proof π your device handed over. There's no name, date of birth, address or photo anywhere inside it. Only the claims you chose to reveal.
