Security and privacy boundary

Original documents and image pixels are processed locally by the protection pipeline.
Reversible mappings and restore keys remain local and structurally outside the Protected Library exposed to AI through MCP.
Users review findings and can keep or protect individual detected values before generating a safe copy.
Protected images use destructive pixel redaction rather than a cosmetic overlay-only approach.
Optional remote connectivity is authenticated and exposes only already-protected Library content, never original values or restore mappings.

Regulatory support

Designed to support GDPR privacy-by-design and data-minimization practices, EU AI Act human-oversight and data-governance workflows, and U.S. privacy/security controls including CCPA/CPRA and the NY SHIELD Act.

Important: Privacy Gate is a technical safeguard, not legal advice, an audit, or a certification of compliance. Automated detection may require human review, and organizational compliance depends on the complete workflow, policies, contracts, jurisdiction, and use case.

Distribution and support

Privacy Gate 0.5.0 is available for Windows and macOS. The Microsoft Store edition is signed and distributed through Microsoft Store. Direct Windows and macOS release artifacts are published with SHA-256 checksums; current direct macOS packages are not Apple-notarized.
