Common Questions
Quick answers to the things people ask us most.
How does the PII engine actually work?
Everything runs in your browser's RAM using native JavaScript regex patterns and the compromise.js NLP library. When you paste text, the engine scans for 50+ entity types (names, emails, phones, IDs), replaces them with deterministic tokens like
[NAME_1], and stores the mapping in volatile RAM. Zero data leaves your device — you can verify by running in Airplane Mode. I lost my PRO license — how do I recover it?
Your PRO license is stored locally in your browser's
localStorage. If you cleared your browser data or switched devices, check your email for the original payment receipt from Paddle. Click the license activation link in that email, or forward the receipt to support@privacyscrubber.com and we'll send you a fresh activation link within hours. How does Reverse Scrubbing (Reveal) work?
After scrubbing, the engine keeps a sessionMap in RAM — like
[NAME_1] → "John Doe". When you paste the AI response back and click "Reveal", every token gets replaced with the original value. This map exists only for the current tab session and is destroyed on page reload. Learn more →Does PrivacyScrubber support enterprise deployment?
Yes. The Enterprise tier includes an on-premise source code license, air-gapped operation (no CDN needed), Chrome MDM integration for 10,000+ seats, and dedicated GRC support. Contact us using the form above for custom pricing and a technical evaluation call.
Can I verify the zero-server claim myself?
Absolutely — and we encourage it. Open DevTools (F12), go to the Network tab, enable Airplane Mode, then scrub a document. You'll see zero outbound requests. The entire engine runs client-side in WebAssembly and JavaScript. This is our "Airplane Mode Verified" trust signal, and it's the strongest proof we can offer: if the network is off and it still works, no data was ever sent.
The engine didn't detect a specific name — why?
Our General profile uses NLP + regex patterns optimized for English names. Uncommon names, abbreviations, or non-Latin scripts may require a Custom Regex Rule (PRO). You can also switch to a specific Industry Profile (Medical, Legal, Finance) which includes broader entity recognition for specialized formats.
