Your photos are already on your phone. Tsuzuru gives a few of them a page, a line of your own words, and a cover — so they become a book instead of a scroll. MAKE A BOOK • Pick photos you already have. A book takes about five minutes. • Three kinds of page: photo only, photo with words underneath, or words alone. • Your writing sits below the photo, never on top of it. Longer passages simply take more of the page. • Add today's page straight from the shelf — no menus in between. READ IT LIKE A BOOK • The cover opens. Pages turn under your finger, with the weight and the sound of paper. • Lean the phone and light runs across the page. • Tap a photo to lift it out and look closer. • Leave a bookmark and come back. SHARE IT • Turn a book into a vertical video, ready for Instagram, TikTok or anywhere else. • Or publish a book and send the link. On the web the link shows the cover and the title; the book itself opens in the Tsuzuru app, and lands on that reader's own shelf. • A published book is reachable only by its link. There is no feed, no search, and no way to browse other people's books. WHAT IT COSTS • Making, reading and exporting video are free, with no limit. • You can keep three books published at a time, for three months each. Premium is a one-time purchase that raises this to 1,000 books for a year each, removes banner ads, and removes the Tsuzuru card from the end of your videos. ABOUT YOUR PRIVACY • No account. No sign-up. • Book photos and text are sent to our server only when you choose Publish, one book at a time. You can also save or share videos through your own actions. • Without Premium, a banner may appear at the bottom of the bookshelf, never while editing, reading or exporting video. Personalized ads may be requested only if you allow tracking and your regional consent choices permit it. If you decline tracking, ad requests are non-personalized. Your book features work even if you decline. • An ad consent form may appear depending on your region. When privacy choices are required, Ad privacy choices appears in the bookshelf menu. • Separately from book publication, Firebase is used for usage analytics and crash reporting. Photos, text and book titles are not included in analytics events. • A published book includes re-rendered photos, text, its title and layout. Original photo files and their embedded GPS metadata are not sent. Terms: https://tsuzuru.tsukuruya.me/en/terms Privacy: https://tsuzuru.tsukuruya.me/en/privacy
