## What is Sumi Book?

Sumi is a beautifully crafted, native reader for the books, manga and comics you already own or have the right to read.

Sumi comes empty by design. It includes no catalog, no content, and no built-in sources — you decide what to read. Import your own files, or add a source by pasting the web address of a site you are entitled to access. Sumi is the elegant reading experience on top; the library is yours.

A READER, NOT A LIBRARY • Ships with zero content and zero pre-loaded sources • Import your own files (.cbz / .zip) straight from the Files app • Add your own source — nothing is bundled

DESIGNED FOR READING • A refined dark interface made for long sessions • Smooth paged and continuous (webtoon) reading modes • Right-to-left support for manga • Remembers your place across your whole collection

NO ADS, EVER Sumi shows no advertising. The reading view is just the page — nothing between you and your story.

PREMIUM Unlock the full experience: • Incognito mode — read without saving history or progress • App Lock — guard your library with Face ID, Touch ID, or a passcode • Backup & restore — export and recover your entire collection • Premium themes — including the dusk-rose Sakura palette • Offline downloads — keep what you're reading with you

YOUR RESPONSIBILITY Sumi is a neutral reading tool. It is not affiliated with any website, publisher, or content, and cannot guarantee the availability of any third-party source. You are responsible for ensuring you have the right to access whatever you add. Please support the authors and publishers you love.
