This extension does not collect, store, or transmit any personal data or user content. All processing happens locally in your browser: pages you fetch are read directly by the extension using your own browser session, and the resulting EPUB file is generated and saved to your device — nothing is sent to the developer, to any analytics service, or to any third party. No account, login, or personal information is required to use this extension. Any data (URLs, chapter selections) exists only in the extension's local session and is not persisted beyond your device's own browser storage. For questions, contact b.a.espasandin+EPUB@gmail.com.
