Privacy

In short

• No account and no registration.
• No advertising cookies.
• Google Analytics only if you accept it in the cookie banner (see below).
• Your preferences (language, tool settings, ticked tasks in the training paths, cookie choice) are stored only in your own browser (local storage); you can delete them at any time by clearing the site data.

Microphone (tuner)

The tuner asks your permission to use the microphone. The sound is analysed only inside your browser: it is never recorded, stored or sent anywhere.

Server logs

Like every website, the web server temporarily records technical data of each request (IP address, date, requested page, browser) to deliver the pages and protect the service. These logs are not used to profile visitors.

External services

Fonts, scripts and images are loaded from this site. The only exception is the Google Analytics script (googletagmanager.com), which measures visits only after your consent.

Google Analytics

With your consent we use Google Analytics 4 (Google Ireland Ltd.) to count visits and understand which pages are useful. Until you click Accept no analytics cookies are set (Google Consent Mode v2), and the IP address is anonymised. You can change your choice at any time by clearing the site data in your browser: the banner will appear again.
