Privacy and Terms
Last updated November 11, 2026
The short version
- Wondrous Library is a student project shared with a small group for testing. It is not a Harvard product and is not affiliated with or endorsed by Harvard University.
- Your books, pages, pictures, videos and voice recordings stay in your own browser on your own device. They are not uploaded to us.
- An account is optional. If you make one, we keep your email, your profile and the list of your books so you can sign in again.
- Nothing is sold, there are no ads, and there is no tracking.
- Your work stays yours.
1. What stays on your device
Everything you put inside a book stays in your web browser's own storage on the device you are using. That includes pages, pictures, PDFs and slides you import, notes, videos, GIFs and voice recordings. None of it is sent to our servers.
Clearing your browser's data for this site, or using a private window, can erase your books. Use Backup โ Save backup to keep a copy you control. A backup file contains your books and settings, so store it somewhere you trust.
2. If you create an account
An account lets your profile and book list follow you between devices. If you create one, we store:
- Your email address and password. The password is handled by our sign-in provider and stored in encrypted form; we never see it.
- The profile details you choose to fill in, such as your name, photo, headline and links. Profile details are public: anyone using the site can see them, so only fill in what you're happy to share. Your sign-in email is never shown unless you also type it into the profile's public email field.
- Your book list: each book's title, cover design and settings, any clip notes, and whether it is public. The pages inside your books are not uploaded.
This data is stored with Supabase, a hosting provider, on servers in the United States. It is used only to sign you in and keep your list in sync. Supabase sends account emails, such as confirming your address or resetting your password.
3. Public shelf
Books are private unless you mark them Public. Your public shelf shows your profile card and the books you made public to anyone who has its link. Only make something public if you are comfortable with anyone seeing it.
4. What we don't do
- We don't sell, rent or share your information.
- We don't show ads or use advertising or analytics trackers.
- We don't read the contents of your books.
- We don't use your work to train AI.
5. Other services the site uses
The site is hosted by Vercel. Fonts load from Google Fonts, and some code libraries load from public code sites (cdnjs, jsDelivr). Like any website, these services can see your device's IP address when they send you a file. The planner's calendar and email features only work inside Claude and are not used on this site.
6. Deleting your information
- A book: open it and choose Delete book. Its pages are removed from your browser.
- Your account: go to Profile โ Delete account. This removes your account, profile and book list from our servers. You can also choose to wipe the books on that device at the same time.
- Everything on a device: clear this site's data in your browser settings.
7. Using Wondrous Library
- Who it's for. This test version is for adults, age 18 and over. Please don't create an account for a child.
- Your content is yours. You keep all rights to what you make. Publishing a book on your public shelf gives the site permission to show it there until you make it private or delete it.
- Only add what you have the right to share. Don't upload other people's copyrighted work, private information, or photos of people, especially children, without their permission.
- Respect classmates and school rules. Don't upload confidential course materials, other students' private information or grades, or anything your program's policies don't allow you to share.
- Be kind. Don't use the site to harass anyone or to share anything illegal or harmful. We may remove public content or accounts that break these rules.
- It's a test version. The site is provided as is, and things may change, break or go away. Keep backups of anything important. To the extent the law allows, we aren't responsible for lost content.
8. Changes and questions
If these terms change, the date at the top will change too. Questions or requests, including deleting your data, can go to the person who invited you to try Wondrous Library.
