What You Can Report
You can send feature requests, import failures, chapter parsing issues, playback or read-aloud problems, cover display issues, bookmark and progress issues, and content corrections.
Common Notes
Supported Files
CantoListen supports common reading and audiobook files, including TXT, EPUB, MP3, M4A, and M4B. Encoding, chapter structure, and audio metadata can affect parsing results.
Local-First Design
Imported books, audio, covers, chapters, playback progress, and bookmarks are stored on your device by default. Unless you choose to send feedback email or share files, the app does not actively upload your imported content.
Import Sources
You can import from iOS Files, iCloud Drive, cloud drives, WeChat, browsers, email, or other apps that support sharing. Available locations depend on your iOS file providers and installed apps.
Privacy and Terms
The privacy policy and terms of use are available on this website and from the Settings screen inside the app.
