Privacy Policy

1 Introduction

Welcome to Readlet PDF Viewer. Readlet is a Chrome browser extension that replaces Chrome's default PDF viewer with a modern, beautiful reading experience.

This Privacy Policy explains how we handle information when you use our extension. The short version: We don't collect, store, or transmit any of your personal information. Your documents stay on your device, always.

2 Information We Collect

We believe in privacy by design. Readlet is engineered to function without collecting personal information.

These preferences are stored in your browser's local storage and are never transmitted externally.

3 How We Use Information

Readlet processes information entirely locally on your device:

• URL Detection: We detect PDF file URLs to open them in Readlet. This happens locally and is not logged.
• PDF Rendering: Your PDF files are processed within your browser to display them beautifully.
• OCR Processing: Text extraction from scanned documents happens locally using Tesseract.js.
• Preference Storage: Your viewing preferences are saved locally for a consistent experience.

All operations happen client-side. No data is ever sent to external servers.

4 Data Storage

Readlet uses your browser's local storage for preferences. This data:

• Remains exclusively on your device
• Is never synchronized to any cloud service by us
• Can be cleared through your browser settings
• Is automatically removed if you uninstall the extension

We do not operate any servers that store user data.

5 Third-Party Services

Readlet does not integrate with any third-party services that collect user data:

• No Analytics: We don't use Google Analytics or any analytics platform.
• No Advertising: We don't display ads or use advertising networks.
• No Tracking: We don't use tracking pixels, beacons, or similar technologies.
• No External APIs: PDF processing happens entirely offline using bundled libraries.

6 Permissions Explained

Readlet requires these Chrome permissions to function:

These permissions are used exclusively for PDF detection and display. We do not use them to read or transmit other browsing data.

7 Data Security

Your data security is guaranteed by our architecture:

• No Data Transmission: Since we don't collect data, there's nothing to secure in transit.
• Local Processing: All rendering and OCR happens in your browser's sandboxed environment.
• No Server Infrastructure: We don't operate data collection servers.
• Open Source Libraries: We use well-maintained, auditable libraries for PDF processing.

The most secure data is data that's never collected.

8 Children's Privacy

Readlet is a general-purpose PDF viewer not directed at children under 13. However, since we collect no personal information, we are inherently compliant with COPPA and similar regulations.

Parents can be confident that no data about their children is collected by Readlet.

9 Chrome Web Store Compliance

In accordance with Chrome Web Store Developer Program Policies:

Continued use of Readlet after changes indicates acceptance of the updated policy.
