Local Processing
No data ever leaves your browser. Verified by local regex & NLP.
Free & Forever
Built by an independent developer. No subscriptions, no ads, just pure security.
One-Click Send
Auto-mask and submit your prompt in a single click. Zero friction.
Security by Design.
We believe privacy isn't just a feature—it's the foundation. Privatus is architected to keep your PII safe without sacrificing utility.
Local Storage Only
Your settings and masking history are stored locally in your browser. We don't have servers. We don't have a database.
Transparent Permissions
We only request permissions (like `activeTab` or `sidePanel`) when strictly necessary for the extension to function.
Side Panel Workflow
Works alongside your chat. No need to copy-paste sensitive data into separate third-party apps.
No External Scripts
Self-contained logic. We don't fetch or execute remote code, ensuring what you install is exactly what runs.
What if you don't mask?
Every unmasked prompt is a permanent record. Once sent, you lose control of that data forever.
Shared Company Accounts
Using ChatGPT Team or Enterprise? Your workspace admins and colleagues can often search and view your chat history. Don't accidentally leak your salary, HR complaints, or client secrets to the whole office.
AI Model Training
Default settings often allow AI companies to train on your data. Your proprietary code and sensitive strategies could become part of the next public model's knowledge base.
Future Ad Targeting
As AI platforms monetize, your deep personal insights and chat history will become a goldmine for advertisers. Build your privacy defense now, before the ads start.
Accidental Leaks
Even if you trust the AI provider, do you trust their security? If your account is hacked, your entire unmasked history is exposed. Masking ensures your secrets stay secret, even after a breach.
