Your books, notes and reading history stay on your own device. The web server hands out this reader and the built-in Getting started guide, and keeps ordinary web-server access logs of requests for those files. It does not receive your books, notes or reading history.
The reader is built on the following libraries. Their licenses require that their notices are kept with the software, so they are reproduced here in full.

This reader does not load or ship any web fonts. The cover of the built-in guide was drawn for this project, and its lettering is set in Linux Libertine, which is licensed under the SIL Open Font License.
A private edition of this reader, made for a particular group, can host specific books for that group. Those books belong to their owners and are shared with the group by the person who set up that edition.
Books you add to your library are your own copies of files you already have. Their copyright belongs to their authors and publishers, and the reader does not copy or upload them.
