About Tsundoku

Tsundoku is a Japanese word for the habit of acquiring books and letting them pile up unread. We think that is a beautiful problem to have.

This is a small, quiet place for people who love books. You catalogue what you own, share shelves with friends, and maybe -- when the right moment comes -- lend a book to someone who needs it more than your shelf does.

Why this exists

Reading is good for you. It makes you slower in the best way. It gives you words for things you already felt but could not say. We want more people to read, and we think the best way to make that happen is through friends -- not algorithms, not recommendations from strangers, not bestseller lists.

If your friend has a book you are curious about, you should be able to borrow it. If you have a shelf full of novels gathering dust, maybe someone in your circle would give them a better life. That is all this is.

Your data

We keep things simple and honest:

• —Your data is not sold to anyone. Not now, not ever.
• —We do not run ads. We do not track you across the web.
• —We store your email, name, and the books you add. That is it.
• —Profile images are compressed and stored securely. Nothing leaves this platform.
• —Your shelves are private by default. You choose what to share and with whom.

We built this because we buy too many books ourselves and thought others might relate.

Invitation only

Tsundoku grows slowly, by invitation. Every new member gets five invite codes to share with people they trust. Good things stay small for a while.

If you have a code, you are already welcome.
