2ndBook is an app about books and about the people who read them. Your personal library, your book club, swapping books with other readers and a comfortable reader all live in one place. YOUR LIBRARY • Add books and documents; by ISBN or a cover photo the fields fill in automatically. • Read offline: local books open with no network and no mandatory sync. • Open books in 2ndBook straight from Files and Telegram via Share — they go right into your library. • EPUB, FB2, MOBI, PRC, DOCX, ODT, RTF, TXT, MD, HTML, PDF and CBZ open in the app’s reader. DJVU, AZW, AZW3, KF8 and CHM are stored and synced, but open in an app on the device. • Listen to audiobooks, book podcasts and video sound with the screen off, with controls in the notification shade and on the lock screen. • Reading progress, bookmarks and favourite quotes sync across your devices. • Select text to save notes and quotes in EPUB, TXT, FB2, DOCX, HTML and Markdown — they gather in one list and open the book right where you made them. • Several accounts on one phone: each keeps its own library, bookmarks and progress. BOOK CLUBS • The club picks its book by vote, and everyone reads it together. • An author or a partner starts a club. • Discussion opens as you read: until you reach a chapter you see only the topic's title — spoilers stay closed. • A club can be open (join in one tap, no request), link-only or invite-only. • Schedule a meeting with an "I'm coming" reply. A coffee break is its own club activity: members split into small groups. • Su-Li-Fa, the club's quick game: the winner names a book first in the next cycle — the vote still happens. • Pass the paper copy to the next member: the club remembers who handed it to whom. • Every club has a chat of its own. BOOKS BETWEEN PEOPLE • Post a book you are ready to sell, gift, swap or lend. • Find other readers' books through search and filters — by genre, from classics to art, photography and design. • Say which format and language you are waiting for — paper, e-book or audio, in Russian, English or Kazakh. • An order takes name, phone and e-mail from your profile and the address from «My addresses». • Give books away: the Gifts section shows what you handed on and what you received, with a clear status for every handover. • Agree the details in the in-app chat. The seller sees the recipient's address and contacts only while handing the book over. • Rate each other after a deal, so the community feels safer. BOOKSHOP PARTNERS • E-books and audiobooks are published by book partners from their storefront. «Become a book partner» is free. • «Read» puts a partner’s book straight into E-BOOK, and it opens offline; if there are several formats, choose one. WHAT ELSE IS HERE • Notifications about what actually matters: a reply in chat, the status of your book, an answer from support. • Support answers inside the app. When it needs more details, the question arrives right in your report, and you answer it in the «Feedback» section. • Dark and light themes; Russian, English and Kazakh. SAFETY AND RESPECT FOR THE READER • Listings pass moderation before publication. Any post can be reported, including for copyright infringement, and any user blocked right from the app; we review every report. • Age ratings on books: restricted editions are unavailable to readers who have not given a date of birth or are below the required age. • We show no ads and do not sell your data. • No paid subscriptions and no in-app purchases: nothing is locked behind a payment. • Readers settle up directly — 2ndBook neither holds nor transfers money. • You delete your account right in the app — immediately, with its files and contacts. • «Delete» on your feedback really erases its text, contacts and screenshots. Legal documents and the privacy policy are in the app and at secondbook.kz. Build your library and give books a second life — with 2ndBook.
