No. Everything runs in your browser - your file never leaves your device. How this is verifiable
An EPUB is essentially a ZIP archive of XHTML chapters plus a control file (the OPF) that defines the reading order - the so-called spine. That is great for reading, but awkward when you only need the plain text: to quote, to search, to paste into a notes app or to process it programmatically. This tool unpacks the EPUB, reads the chapters in exactly the spine order and outputs a single TXT file with the running text.
The conversion runs entirely locally in your browser (fflate for unpacking, pure JavaScript - no upload, even offline). From each chapter the XHTML markup is removed, block elements such as paragraphs and headings become line breaks, and HTML entities are turned back into real characters. Images, fonts and layout are deliberately dropped - this is purely about the readable text.
This helps when you need the content of an e-book as a simple text file, for instance for a full-text search, a script or importing into an editor. DRM-protected EPUBs cannot technically be read and are rejected honestly rather than producing unusable text. Pure formatting, the heading hierarchy and embedded media are lost - if you want to keep the layout, another format is the better choice.

Limitations: It outputs plain running text in reading order - without images, fonts, layout or clickable links. Footnotes and tables are simplified. DRM-protected e-books cannot technically be read and are clearly rejected. The chapter structure appears only as blank lines between sections.
No. The unpacking and extraction happen entirely locally in the browser - even offline.
No. DRM-protected EPUBs are encrypted and are rejected honestly; without DRM it works.
No. It outputs plain text; fonts, images and layout are dropped. Paragraphs are kept as line breaks.
Yes. The chapters are merged in the reading order (spine) stored in the EPUB.
