Privacy Policy

Last Updated: May 2026

1. Core Privacy Principle: 100% Offline Processing

ChapterWave is built with your privacy as the fundamental priority. The core functionality of the application—converting your documents (EPUB, PDF, DOCX, TXT) into audiobooks using neural voices—happens entirely locally on your own machine. We do not have access to your books, your documents, the generated audio, or your usage habits.

2. Information We Do Not Collect

• No Document Uploads: Your files are never uploaded to any cloud server or third-party service.
• No Telemetry: We do not track how many books you convert or what features you use inside the app.
• No Voice Processing Data: The AI voice synthesis is powered by a local ONNX model downloaded to your device upon installation.

3. Information We Collect (Website & Purchase)

If you purchase ChapterWave through our website, our payment processor collects necessary billing information (such as your email address, name, and payment details) to process the transaction and deliver your license key. We use this information solely for order fulfillment and customer support.
