Privacy and analytics

This page explains how The Quantum Investor’s Notebook measures readership and how you can control optional analytics cookies.

The Quantum Investor’s Notebook is a small, independent research notebook. I use analytics to understand which pages readers find useful, how visitors move between notes and articles, and where the site could be improved.

Analytics tools

Google Analytics 4 helps measure readership, including visits, page views, and how readers find the site.

Microsoft Clarity helps show how readers interact with individual pages, including patterns such as clicks and scrolling, heatmaps, and session recordings. I use this information to improve the structure and usability of the site. Clarity is loaded only if you accept analytics cookies.

Your choice about analytics cookies

Optional analytics cookies are disabled by default. When you first visit, you can accept or reject them. The content and features of the site remain available either way.

If you accept, Google Analytics and Microsoft Clarity may store first-party analytics cookies in your browser, and Microsoft may also set its own cookies on its clarity.ms and bing.com domains. These cookies help distinguish visits and connect page views into more complete sessions.

If you reject, optional analytics cookies are not stored and Microsoft Clarity is not loaded. Google Analytics may still perform limited cookieless measurement. This allows basic readership measurement while avoiding optional analytics cookies.

Your choice is saved in your browser so that it can be remembered on later visits. You can change it at any time using the Cookie settings link in the footer.

If you accept and later choose Reject in Cookie settings, Clarity is stopped on the current page and its first-party cookies are deleted. Cookies that Microsoft set on its own domains (clarity.ms, bing.com) cannot be removed by this site; you can delete them in your browser settings.

Advertising

This site does not use advertising cookies. Advertising-related permissions remain disabled.

Newsletter

Signups for The Notebook Ledger newsletter, including the form on the homepage, are handled by Beehiiv, which processes your email address to deliver the newsletter and may store its own cookies to support the form and track where signups come from.
