Privacy policy
Effective 15 July 2026. This policy explains the limited data this static guide may process.
Information collected automatically
The hosting provider may process standard request data such as IP address, browser type, requested page, time and security signals. This information is generally used to deliver the site, prevent abuse and diagnose failures.
Optional analytics
The site contains environment-ready hooks for Google Analytics and Microsoft Clarity. These tools are disabled when their public configuration IDs are unset. If enabled, the providers may process usage information according to their own policies, including page visits, device details and interaction data.
If you contact us, we receive the information you choose to send, including your email address. It is used to answer the request, investigate a correction or handle a rights issue. Do not send passwords, financial information or sensitive identity documents.
Cookies and local storage
The site itself does not require an account or use a first-party login cookie. Configured analytics providers may use cookies or local storage. Browser controls can restrict or remove that storage.
