Privacy Policy

Your privacy is our top priority. Learn how we protect your data.

Zero Data Collection

We don't collect, store, or transmit your documents or personal data. Everything happens in your browser.

Local Processing

All PII detection and redaction happens locally on your device. Your sensitive data never leaves your browser.

Data Processing

What We DON'T Do

  • • We don't upload your documents to our servers
  • • We don't store your text or files anywhere
  • • We don't track your document content
  • • We don't share your data with third parties
  • • We don't use your documents for training or improvement

How It Actually Works

  • • Machine learning models run entirely in your browser
  • • Documents are processed in your device's memory
  • • Results are generated and displayed locally
  • • Exported files are saved directly to your device
  • • No network requests are made with your content

Technical Implementation

Client-Side Architecture

Our application uses modern web technologies to ensure complete privacy:

  • WebAssembly & WebGPU: High-performance ML inference in the browser
  • Local Storage: Temporary data is stored only in browser memory
  • No Analytics on Content: We never analyze your document content
  • Offline Capable: Works without internet connection after initial load

Website Analytics

While we don't collect your document data, we do use privacy-focused analytics to understand how our website is used:

What We Track

  • • Page views and navigation patterns
  • • General usage statistics (number of files processed, export formats used)
  • • Performance metrics (load times, error rates)
  • • Basic device information (browser type, screen size)

What We DON'T Track

  • • Document content or text
  • • Detected PII items
  • • File names or file contents
  • • Personal identification information

Open Source Transparency

Our commitment to privacy is backed by transparency. The complete source code of this application is available for review, allowing security experts and privacy advocates to verify our privacy claims.

Verify Our Claims

You can inspect the source code, review network requests in your browser's developer tools, and even run the application offline to confirm that no data is transmitted to external servers.

Browser Storage

Our application may use browser storage mechanisms for the following purposes:

  • Local Storage: Save your preferences (detection settings, export format)
  • Cache Storage: Store ML models for faster loading
  • Session Storage: Temporary storage during your session

None of this stored data contains your document content or detected PII. You can clear this data at any time through your browser settings.

Security Measures

Technical Security

  • • HTTPS encryption for all connections
  • • Content Security Policy headers
  • • Cross-Origin Resource Sharing controls
  • • Subresource integrity verification

Privacy by Design

  • • No server-side processing
  • • Memory-only document handling
  • • Automatic data cleanup on page reload
  • • Zero persistent storage of content
