Frequently asked questions

What do I need to get started?

Just a browser. The exercises run right in the browser, no separate installs needed.

How does payment work?

A monthly or yearly subscription (€19.90/month or €199.90/year) that gives you access to the whole course catalog — including courses added later. Cancel anytime from your account.

Can I try a course before subscribing?

Yes. Registering lets you start a free course right away, at no cost — a good way to see what the teaching is like before deciding to subscribe to the rest.

Is there a time limit?

No time limit on studying — you move at your own pace for as long as your subscription is active. After canceling, access to paid courses continues until the end of the current billing period; free courses and any certificates you've already earned stay yours after that.

Who are the courses for?

The starting courses assume no prior experience. Follow-up courses state in their description which earlier course they assume you've finished.

What payment methods do you support?

Payments are handled securely through Stripe.

Can I cancel my subscription?

You can cancel anytime from your account — access continues until the end of your current billing period. On top of that, cancelling within the first 14 days is completely free: you get a full refund, no questions asked.
