How It Works: The Mathematics of Absolute Privacy.
We don't just promise privacy; we mathematically guarantee it. Powered by Zero-Knowledge concepts and Cryptographic Hashing.
Dynamic QR Shield
Your app generates a unique, time-limited QR code for every interaction. Shops verify the token, not your identity. Once scanned, the code self-destructs.
Isolated Identities
You are a different person to every shop. We use one-way hashing to generate a unique ID per merchant. Shops cannot collude to track your cross-store behavior.
UID_merchant = Hash(User_ID + Merchant_ID)Irreversible. The same person produces a different UID at every store, so merchants can never link your activity across shops.
The Communications Firewall
Merchants command the system to reward 'UID #8923'. Our servers do the matching and push the notification. The merchant never touches your contact details.
Frequently Asked Questions
The hard questions about cryptography and trust.
Your device's secure enclave holds the cryptographic proof. When you claim a reward, the app signs a challenge locally and presents a verifiable token — no personal identifier ever leaves your phone.
We don't store PII (Personally Identifiable Information). A hack would only reveal useless, hashed tokens that cannot be reversed into a name, number, or payment method.
