Privacy Policy

1. Introduction

We respect your privacy and are committed to protecting your personal data. This Privacy Policy explains how we handle information when you use our HEIC to PDF converter service. Our commitment to privacy is fundamental to our service design.

2. Core Privacy Principles

2.1 Complete Client-Side Processing

  • 100% Local Processing: All image conversion occurs entirely within your web browser
  • Zero Server Uploads: Your images are never uploaded to our servers
  • No Network Transmission: Image data never leaves your device during processing
  • Memory-Only Processing: Images are processed in browser memory and automatically cleared

2.2 No Image Data Collection

  • We have no access to your image files or their content
  • We cannot see, analyze, or store any images you process
  • We collect no metadata from your image files
  • All processing happens locally using WebAssembly and JavaScript technologies

3. Information We Collect

3.1 Personal Information

  • We collect NO personal information such as:
    • Names, email addresses, or contact details
    • User accounts or profiles
    • Personal identifiers of any kind
  • No registration required - the service works anonymously

3.2 Image Data

  • Your images are NEVER transmitted to our servers
  • Local processing only - conversion happens entirely in your browser using:
    • WebAssembly for HEIC/HEIF decoding
    • Canvas API for image manipulation
    • PDF-lib for PDF generation
  • Automatic cleanup - images are cleared from memory when you:
    • Close the browser tab
    • Navigate away from the page
    • Clear the results manually

3.3 Technical Information (Anonymous Only)

We may collect minimal, anonymous technical data:

  • Browser type and version (for compatibility)
  • Operating system (for performance optimization)
  • Screen resolution (for UI optimization)
  • Page views and session duration (for service improvement)
  • Referral sources (to understand how users find us)
  • Error reports (to improve service reliability)

Important: This technical data is:

  • Completely anonymous and cannot be linked to individuals
  • Aggregated and used only for service improvement
  • Never combined with image data (which we don't have access to)

4. How We Use Information

4.1 Image Processing

  • Images are processed solely for format conversion from various formats to PDF
  • No analysis, indexing, or content extraction occurs
  • No machine learning or AI processing of image content
  • Processed images remain under your complete control
  • Conversion logic varies by format:
    • HEIC/HEIF: Decoded to bitmap, then embedded in PDF
    • JPEG/PNG: Directly embedded in PDF (no re-encoding)
    • Other formats: Converted to JPEG, then embedded in PDF

4.2 Technical Data Usage

Anonymous technical information may be used to:

  • Optimize performance for different devices and browsers
  • Identify and fix compatibility issues
  • Improve user interface and user experience
  • Monitor service availability and performance
  • Prevent abuse and ensure service security
  • Plan for infrastructure scaling

5. Data Storage and Security

5.1 Image Data

  • Zero server storage - no image data ever reaches our servers
  • Browser-only processing - all operations occur in your device's memory
  • Automatic cleanup - processed images are immediately eligible for garbage collection
  • No caching - we don't cache or store any image data locally or remotely

5.2 Technical Data

  • Minimal collection - only essential anonymous metrics
  • Secure transmission - any technical data transmitted uses HTTPS
  • Limited retention - technical data is automatically purged according to retention policies
  • Industry-standard security - we employ appropriate security measures for any collected data
  • No personal identifiers - technical data cannot be used to identify individuals

6. Third-Party Services and Dependencies

6.1 Client-Side Libraries

Our service uses the following client-side libraries (processed in your browser):

  • heic-decode: For HEIC/HEIF image decoding (WebAssembly-based)
  • @cantoo/pdf-lib: For PDF generation and manipulation
  • Canvas API: Browser-native image processing

These libraries process data entirely within your browser and do not transmit data externally.

6.2 Analytics Services (Optional)

We may use privacy-focused analytics services to understand service usage:

  • Data collected is anonymous and aggregated
  • No personal identifiers are tracked
  • You can opt-out using browser settings or privacy extensions

6.3 Content Delivery and Hosting

  • Our service may be delivered via Content Delivery Networks (CDNs)
  • CDNs only serve static files (HTML, CSS, JavaScript) and have no access to your image data
  • Any CDN caching is limited to static application files, never user data

7. Cookies and Local Storage
