Privacy Policy

Last updated August 21, 2026.

Who we are

Our website address is https://isbnly.com.

What we collect

isbnly.com doesn't have user accounts, comments, or file uploads, so there's very little to collect. When you visit the site, our server logs standard technical information (your IP address, browser user agent, and the pages you request), the way essentially every website does, for security and abuse prevention. We don't currently run any analytics or advertising trackers, and we don't set any cookies beyond what's strictly necessary to serve the page you asked for.

Third-party links

Book pages link out to ISBNLab.com (the API that powers our book data) and to third-party booksellers such as Amazon and Bookshop.org for purchase links. Those sites have their own privacy policies that we don't control. Check their pages directly for how they handle your data.

Children's privacy

isbnly.com isn't directed at children under 13, and we don't knowingly collect personal information from them.

Changes to this policy

If how we handle data changes (for example, if we add analytics or cookies down the line), we'll update this page and the "last updated" date above.
