No cookies on this website

This website sets no cookies. Nor does it use your browser's local storage (local storage, session storage) or any other storage on your device for tracking.

Analytics without cookies

We use Ahrefs Web Analytics for visitor statistics. It sets no cookies and stores nothing on your device. Our privacy policy describes the data it processes.

Payment through Stripe

When you buy a course, you are taken to Stripe's checkout page (checkout.stripe.com). Stripe may set cookies there that are strictly necessary for the payment and serve fraud prevention and payment security. Such cookies do not require consent (section 25(2) no. 2 of the German Telecommunications Digital Services Data Protection Act (TDDDG)). Stripe's privacy policy applies.

Embedded content

This website does not embed third-party content such as videos, maps or social media posts.

No cookie banner

Because we use no cookies or similar technologies that require consent, we show no cookie banner to visitors in Germany or anywhere else. If that changes, we will update this notice and ask for your consent first.
