fix: Keep BookOrbit sign-in details on the server they belong to
When a BookOrbit server answered a request by pointing somewhere else,
the app followed it and could send the reader's session, and sometimes
what was being saved, to an address it had never checked. Only saving
a reading place or status was protected. Every BookOrbit request now
refuses to be pointed elsewhere.

An open-source ebook reader for Android, and a client for calibre-web, Komga, BookOrbit, liseur-sync and any OPDS catalog: EPUBs on your phone, in sync with your own book server.

About Liseur

Liseur renders EPUBs with the Readium engine, in open typefaces (Literata, Vollkorn, Atkinson Hyperlegible, Inter) or whatever the publisher shipped. Four reading themes: Light, Sepia, Dark, OLED Black. Margins, line spacing, brightness, and page-turn vs. continuous-scroll are adjustable per book or library-wide. Auto-scroll runs at a set pace and continues across chapter boundaries.

A footer shows the page you are on, how much of the chapter is left, and time remaining. Highlights, margin notes, bookmarks, and dictionary lookups are inline; book-level notes live in the notebook. Marking a passage offers three colours, and you tick which of the six you want along with the colour new marks use. Footnotes open as a card over the page rather than sending you to the back of the book.

The library is one shelf whatever the source: local folders, calibre-web, Komga, BookOrbit, liseur-sync, or any OPDS catalog. Series are grouped into stacks tracking reading order, progress, and missing volumes. "Download all books" fills the shelf from a connected server in one go. An empty library also offers a shelf of free books from Project Gutenberg — pick a category and how many books you want, and they are there before there is anything to connect to. Once that shelf is populated, you can ask for 50 more books at a time from the same category and language.

Reading position syncs across devices through calibre-web, Komga, BookOrbit or liseur-sync, down to the exact sentence on the last three. BookOrbit positions travel as EPUB CFIs. A Custom connection can be an OPDS address, a kosync address, or both, so a plain catalog and a sync server that know nothing about each other still add up to a library that follows you. What each server can and cannot do is in docs/SERVER_CAPABILITIES.md.

With liseur-sync you get extras, like settings sync, and better insights of your reading progress across devices.

No trackers, no analytics, no ads, no subscriptions. Liseur only talks to the servers and dictionary sources you configure. See the privacy policy.

  • liseur-sync: Lightweight self-hosted library and sync server. Watched folders, browse, download, positions and reading stats. This will give you the best "kindle/just work" experience compared to the other sync servers.
  • liseur-desktop: Desktop version of Liseur (abandoned).

Development

See DEVELOPER.md for build instructions and architecture notes, and docs/SERVER_CAPABILITIES.md for what each server exposes, what Liseur implements against it, and why the gaps remain.

What's in a name?

Liseur ([li.zœʁ], lee-ZUR) is the French word for an avid reader or book lover. It sounds dignified, like the English word leisure.

Another inspiration was a painting by Pierre-Auguste Renoir portraying Claude Monet as "Le Liseur":
