ZERO-TRUST DATA SANITIZATION (ZTDS) AUDIT CERTIFICATE

CISO Audit Verified

CERT-ID: ZTDS-E9F4C3A72B8D

This document certifies that the prompt and document sanitization process detailed below was executed 100% client-side in volatile local memory under the Zero-Trust Data Sanitization (ZTDS) protocol. Zero plaintext identifiers, customer data, credentials, or proprietary prompts were transmitted across any network or retained on persistent storage.

CISO Compliance Declarations & Privacy Guarantees

1. Zero Network Risk No network request containing prompt contents, files, or sensitive metadata was dispatched during sanitization. All parsing and regex engines operated strictly in the local browser execution thread.

2. Volatile RAM Scoping Plaintext PII and synthetic replacement token maps are allocated strictly within tab-scoped volatile RAM. No tokens are written to localStorage, cookies, or indexedDB, preventing forensic extraction.

3. Reversible Token Bindings Data reversal (Reveal) is executed entirely client-side using deterministic local token dictionaries. PrivacyScrubber functions as a zero-knowledge, zero-storage boundary conduit.
