Zero-Knowledge Architecture

We don't just comply with LGPD and GDPR — we make violations architecturally impossible.

1
Merchant sends customer data
Email, phone number, or any PII enters the system through secure API
2
SHA-256 + Unique Salt
Each merchant has an exclusive cryptographic salt. Data is hashed instantly — the original is never stored
3
Only hashes exist
All segmentation, analytics, and automation operate on hashed data. Even we cannot see the original
4
Breach-proof by design
A data breach would expose only meaningless hashes — no PII, no liability, no damage
// Customer email enters the system
const email = "customer@email.com";
 
// Unique salt per merchant
const salt = merchant.getUniqueSalt();
 
// SHA-256 hashing — irreversible
const hash = SHA256(email + salt);
 
// What we store:
"a7f3b2c9d1e4f5...8b9c0d1e2f3"
 
// What we know about the customer:
nothing. // zero-knowledge ✓

Leadership

Founded on 15 Years of Experience

Otoniel Avila Pinho - Founder & CEO
Otoniel Avila Pinho
Founder & CEO — Privacy Vault Technologies LLC
After processing 2.6 billion email opens and 196 million clicks for enterprise retailers including Casas Bahia, Carrefour, and Walmart Brazil, Otoniel identified a fundamental problem in the marketing industry: the broken trust model of storing customer data in plain text.
That insight led to the creation of Privacy Vault Technologies — the world's first zero-knowledge multichannel retention platform where privacy violations are architecturally impossible. Previously, Otoniel founded and operated SmartBMC (2010-2023), one of Brazil's largest independent email marketing infrastructure platforms, and OTTOTEX in the 1990s, a textile manufacturing company with 500+ employees.
