Privacy Policy

1. Introduction

At PDF to OCR, we are committed to protecting your privacy and ensuring your documents remain private. Our service is designed with privacy as a core principle, not an afterthought. All OCR processing happens locally in your browser using WebAssembly, meaning your files never leave your device.

2. What We Don't Collect

Zero Data Collection: We do not upload, store, or process your documents on any servers. All OCR processing occurs entirely within your browser using our WebAssembly-powered technology.

• No file uploads or storage
• No document content collection
• No metadata or file size logging
• No user accounts or registration required
• No analytics or tracking of your usage

3. What We Do Collect (Limited)

We only collect minimal, non-personal information to ensure our service functions correctly:

• Technical Data: Browser type and version for compatibility optimization
• Usage Statistics: Aggregate traffic data to improve performance
• Local Storage: History of your OCR conversions (stored locally in your browser only)

4. Local Storage & History

Our service stores OCR conversion history locally in your browser's storage (localStorage). This feature allows you to:

• Recover previous OCR results
• Delete individual conversions
• Clear your entire conversion history

This data remains on your device only and is never transmitted to our servers.

5. Data Security

Security is built into our architecture:

• End-to-end processing in your browser
• No network transmission of your files
• JavaScript-based OCR (Tesseract.js) with zero server interaction
• Encrypted local storage for sensitive data

6. Third-Party Services

We use third-party services to provide core functionality:

• PDF.js: PDF rendering (no file uploads)
• Tesseract.js: OCR processing (runs locally)
• Google Translate API: For text translation (only when you explicitly request it)

These services respect your privacy and don't store your documents.
