Security First
We designed Red Shield·Redact with a zero‑trust architecture. Your privacy is not an afterthought — it's the foundation.
100% Local Processing
Your PDF never leaves your device. No file upload, no server — just your browser and your data.
Zero Tracking
We don't use analytics, cookies, or any tracking tools. What you redact stays with you.
Browser Sandbox
The app runs inside your browser's secure sandbox, isolated from the rest of your system.
Encrypted Delivery
Our site is served over HTTPS, ensuring the code you receive hasn't been tampered with.
Auditable Dependencies
We rely on trusted open‑source libraries (PDF.js, pdf‑lib) that are continuously reviewed by the community.
No Local Copies
We don't store any information on your device beyond temporary browser memory, which is cleared on close.
No Special Permissions
The app only requires the file picker to read your PDF — no access to your camera, microphone, or location.
Actively Maintained
We keep dependencies up‑to‑date and monitor for security advisories to ensure a safe experience.
Full Transparency
Our Terms and Privacy Policy clearly state exactly what we do (and don't do) with your data.
