What is collected, why, and your choices.
The NFL Analytics Textbook is a free educational site run by one person. I do not ask you to create an account and I do not directly collect personally identifying information. This page explains the limited data that is collected automatically and how to control it.
I use Google Analytics 4 (measurement ID G-1DZ9CYKN61) to understand which pages are read and how the site is performing, in aggregate. Google Analytics sets cookies and collects information such as your IP address, device and browser type, and the pages you visit; I use it to improve the content, not to identify individual visitors. You can learn more in Google’s privacy policy and opt out site-wide with the Google Analytics Opt-out Browser Add-on.
I display ads served by Google AdSense and its partners. To do this, these third parties may use cookies and device identifiers.
I do not control the cookies set by advertising partners. Please review Google’s privacy and terms for details on how they use data.
Cookies are small text files stored on your device by websites you visit. This site uses them for two purposes: first-party browser storage (your browser’s local storage) to remember preferences such as your dark-mode theme and tutorial progress, and third-party cookies set by the advertising and analytics partners described above. You can block or delete cookies in your browser settings; the site will still work, and your preferences will simply reset.
This site is a set of static HTML files served by Microsoft IIS on a server I operate. There is no third-party website host, no content delivery network in front of it, no database, and no contact form — corrections come by email. Like any web server, it can write standard access logs (IP address, requested URL, user agent, and timestamp) for operation, troubleshooting, and security; those logs are not used to build visitor profiles and are not shared. Fonts, JavaScript libraries, and the advertising and analytics tags described above are loaded from Google and public CDNs, so those requests reach the providers named on this page.
This site is written for adults: it teaches statistics and programming, and part of it covers sports-betting markets with 21+ notices throughout. It is not directed to children, it is not a mixed-audience service, and I do not knowingly collect personal information from anyone under 13 (or under 16 in the EEA/UK). If you believe a child has provided personal information through this site, email me at contact@nflanalytic.com and I will delete it.
If you are located in the European Economic Area, you have rights under the General Data Protection Regulation (GDPR), including the right to access, correct, or delete personal data, to object to processing, and to withdraw consent at any time. The legal bases for processing are consent (for non-essential cookies and ad personalization — requested via the consent message shown on your first visit) and legitimate interests (for operating, securing, and improving the site). You also have the right to lodge a complaint with your local data protection supervisory authority. Email me to make a request.
Under the California Consumer Privacy Act (CCPA), California residents have the right to know what personal information is collected, the right to request its deletion, and the right to opt out of the sale or sharing of personal information. I do not sell personal information; you can opt out of personalized advertising via the links in the Advertising section above, or email me to exercise any of these rights.
I do not sell your personal data. I do not run email marketing. Links to third-party sites (data sources, references) are governed by those sites’ own privacy policies, not this one.
