The Book

Privacy on this site

thebook.ltd · Last updated 10 September 2026

This page covers the thebook.ltd website itself: the pages that describe the apps and link to them. Each app has its own privacy policy, published inside that app and on its store listing, because each one handles a different kind of record. BlackBook's is at thebook.ltd/privacy.

What this site collects

Nothing that you type. The site has no forms, no accounts and no newsletter, and we do not run our own analytics on it. Our hosting provider, Vercel, keeps standard server logs (the address a request came from, the page asked for, the time and the browser's user agent) for a short period to operate and protect the service.

Advertising and cookies

This site uses Google AdSense to show advertising. Third-party vendors, including Google, use cookies to serve ads based on a visitor's earlier visits to this site and to other sites. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this and other websites.

If you have used BlackBook in this browser, the site also sets one first-party cookie, bb_app, which only remembers that the address thebook.ltd should open the app for you rather than this page. It holds no personal information.

The apps are separate

Nothing you record in any of the apps is shared with this site or with its advertising. The records you keep in an app stay on your device unless you turn on that app's own sync, and what advertising a particular app shows, if any, is set out in that app's own policy.
