Was wir bauen, warum, und was Verlage und Leser immer wieder fragen.
Readers have had bought books deleted from their devices and the download option removed. A sealed edition is a file on your license page, in a published format, and no server can take it back.
2026-09-29Store formats tie a book to one app and one account. The sealed edition opens in any modern browser, in the Mac, iPhone and Android apps, and in anything built on the published layout.
2026-09-28Store readers sync position but keep collections per device and annotations one-way. Here position, preferences, bookmarks, notes and shelves follow the license and the account.
2026-09-27Readers complain about sepia that turns text brown, fonts they cannot change and apps that ignore accessibility. The reader has four tuned themes, three fonts including an easy-read mode, and tools for focus and listening.
2026-09-26Logins and phrases are the friction readers quit on. A signed link from the library signs you in for thirty days on that device, and owned books then open with nothing to type.
2026-09-25Collections that only exist on the device that made them are a known failure of store apps. Shelves here belong to the account and group the library everywhere.
2026-09-24Heavy locks make honest readers pay for a few copiers. The ZI² approach keeps reading free of friction and makes a leaked copy traceable instead.
