About & FAQ
Everything you need to know about PromptShield.
Is it truly 100% Offline?
Yes. Once the page loads, you can disable your internet connection. All regex parsing, smart mock injection, and hashing happen locally in your browser using Native JavaScript APIs.
How does the Memory Vault work?
When data is redacted, we store a secure map (e.g., `user1@example.com` -> `real@email.com`) inside your browser's `localStorage`. This allows the tool to "De-Anonymize" the AI's response perfectly, without the real data ever leaving your machine.
