For Public Libraries
A quiet companion for your library users.
Free, private, no account needed. Leaf helps your library users stay on top of their return dates and build a daily reading habit. Nothing to set up, nothing to manage on your end.
Free for every library user, No account, no data collection, Speaks your readers' language
Free for every library user
No subscription, no sign-up. The reading-tracking features stay free.
No account, no data collection
Everything stays on the reader's device. We can't see it.
Speaks your readers' language
Available in 16 languages, matched to the phone settings.
For your library users
Fewer books returned half-read.
Readers borrow with good intentions and run out of time. Leaf turns the return date into a daily reading pace they can actually keep. Seventeen pages today. Twenty-two tomorrow if they missed a day. The math stays honest. The book gets finished.
For your circulation
A reader who finishes one borrowed book comes back for another.
Leaf builds a daily reading habit through quiet streaks and milestones. A reader on a thirty-day streak is a reader who visits your library every month. The habit forms quietly, without leaderboards or nudges that make reading feel like a task.
For your principles
Reader privacy is a library value. It's also a Leaf value.
A reader's library stays on their phone. No account, no public profile, and nothing about what they read is sold or used to target ads. Leaf uses product analytics and crash reports to improve the app. Cloud sync is available for those who want their library across devices, but it is entirely opt-in.

Who builds Leaf
A solo studio. No venture capital, no growth team, no plans to sell your library users' data.
Leaf is built by No Bad Seed Studio, a one-person studio. It is funded by an optional Leaf Pro subscription, a one-time Challenge Pass, non-personalized ads in the free version, and small commissions on optional buy links. That model lets us keep the reading-tracking features free and the data on the device, where it belongs.
Frequently asked questions
Is Leaf really free for our library users?
Yes. Reading tracking, streaks, goals, statistics, and the borrowed-books feature are all free with no subscription. Leaf Pro and the Challenge Pass are optional extras, and library users don't need either.
What data does Leaf collect from our library users?
Their library, progress, streaks, and goals stay on the device unless they choose to turn on sync. Leaf does use product analytics (for example, which screens are used and when a book is added) and crash reporting to improve the app, and the free version shows non-personalized ads. Nothing about what someone reads is sold, used for ad targeting, or turned into a public profile, and Leaf never asks for contact lists.
Do we need to register or sign a partnership?
No. There is no library license, no partnership, no form. Library users download Leaf from the App Store or Google Play like any other app. Recommending it is something staff can do at the desk or in a newsletter.
Is Leaf available in languages other than English?
Yes. Leaf ships in 16 languages including English, French, German, Spanish (Spain and Latin America), Portuguese (Portugal and Brazil), Italian, Polish, Russian, Hindi, Japanese, Korean, Chinese, Arabic, and Turkish. The app uses the phone's language automatically.
