Essential browser storage

The site saves your light/dark theme preference, course progress and badges in local storage. It also stores your cookie choice with the date of your decision in local storage. These functions remain available when analytics is rejected. The administrative sidebar may use a functional cookie to remember whether it is open.

Optional Google Analytics

Google Analytics measures page views only after you expressly accept. It may set analytics cookies such as _ga and _ga_* to distinguish visits, depending on Google's configuration. Google advertising storage, user-data and personalization signals remain denied; this site does not ask for advertising consent.

Your choice

You can accept, reject or customize analytics in the first-visit panel. Reject and Accept are equally available; nothing optional is enabled by default. Reopen Cookie settings from the footer to withdraw or change consent. Withdrawal stops future measurement and reloads the page if the Google tag was already loaded; it cannot undo data already received by Google. Clearing site data resets your choice, so the panel will appear again.

Global Privacy Control

If your browser sends a Global Privacy Control signal, analytics stays off, even if you previously accepted it. You can also clear cookies and local storage using your browser's settings. Last updated: 30 September 2026.
