This Cookie Policy explains how the My Lichess Online Analyzer (MyLOA) website uses cookies and similar technologies when you visit https://www.chessopeninganalyzer.com/ (the "Website"). It should be read together with our Privacy Policy, which describes how we handle personal data more generally.
Cookies help us ensure the Website works correctly, remember certain choices you make, and, where enabled, understand how visitors use our pages so we can improve MyLOA and related services.
You can control and manage cookies as described in the Managing Cookies section below.
Cookies are small text files that a website stores on your device (such as your computer, tablet, or smartphone) when you visit it. They allow the website to recognize your device and remember information about your visit.
Cookies can be:
- Session cookies: these are temporary cookies that only exist while your browser is open. They are deleted automatically when you close your browser.
- Persistent cookies: these remain on your device for a set period or until you delete them. They allow a website to remember you across multiple visits.
Cookies can also be set directly by the website you are visiting ("first-party cookies") or by other domains providing services through that website ("third-party cookies").
We use cookies on the MyLOA Website for the following main purposes:
- Essential operation: to allow the Website to function correctly, for example to load pages securely and remember basic settings that are required to display content.
- Preferences and usability: to remember certain choices you make, such as your cookie consent selections and, where applicable, interface preferences. This helps make your experience smoother when you return to the Website.
- Analytics and performance (where enabled): to collect anonymous or aggregated information about how visitors use our Website, such as which pages are visited most frequently, how long pages are viewed, and any error messages. This helps us understand and improve how people discover and use information about MyLOA.
- Security and abuse prevention: to help protect the Website, prevent misuse, and detect unusual or suspicious activity.
We do not use cookies to show third-party advertising on this Website.

We do not control third-party cookies directly. You can find more information about how such third parties use cookies in their own policies, and you can usually manage their cookies using your browser settings and, where available, the third party's own tools.
We may update this Cookie Policy from time to time, for example to reflect changes in the cookies we use, in applicable laws, or in how we operate the MyLOA Website.
