Methodology & Verification Safeguards

Technical Integrity & Boundaries

This tool operates on mathematically verified algorithms, standard RFC protocols, and authentic registry streams. Results reflect deterministic measurements and should be interpreted alongside holistic investigative context.

Zero-Retention Privacy Guarantee

User privacy is non-negotiable. Candidate files and payloads are evaluated in isolated memory and permanently purged immediately after returning analysis results. We never build databases from user data.
