Cookies and similar technologies

A simple site, including its data use.

This site sets no cookies and contains no analytics, advertising pixels, embedded videos or third-party content. Fonts and images are served locally.

It uses localStorage only to remember language and theme choices you make manually, using the keys koalearn-language and koalearn-theme. These preferences stay on your device and are not sent to the server. You can change them with the controls in the header or remove them by clearing this site’s data in your browser.

Without saved preferences, the entry page uses browser languages and the theme follows your system. No IP geolocation is used. The site activates no tracking tools and has no cookie-consent banner. Technical request data is described in the privacy notice.

The website and the app are separate.

The Android app uses local preferences and integrates AdMob. Advertising choices are managed through Google UMP in the app and, when required, can be changed from Profile. This website does not manage those choices.
