Nett Academy is hosted on the Teachable platform. Teachable provides the hosting, the checkout, and payment collection, acting as our limited payment collection agent. The contract for a course is concluded between you and us. Teachable's own terms apply to your use of the platform in addition to these terms; where they conflict, these terms govern the sale and Teachable's terms govern the platform.

2. What Is Sold

A Nett Academy course is a video course delivered as lessons on this platform, together with the supporting material listed on that course's page. Depending on the course, that material may include a slide deck, a study guide, practice questions, and a starter kit of source files.

3. How a Purchase Is Made

The presentation of a course on Nett Academy is an invitation to purchase, not a binding offer. You make a binding offer by completing the checkout and clicking the order button. The contract comes into effect when we accept your order, which happens automatically on successful payment and is confirmed by the receipt e-mail sent to you.

Before you place your order you can review your selection and the total price, and correct your entries using your browser's back function or by editing the checkout fields.

The contract language is English. We store the contract text and send it to you with the receipt e-mail. Please retain that e-mail.

4. Access and Licence

A course purchase is a one-time payment with no recurring charge, unless a product is explicitly offered as a subscription at checkout.

On purchase you receive a non-exclusive, non-transferable licence to use the course material for your own personal learning and for your own professional work. You may not:

  • share, resell, sublicense, rent, or publish the material, or make your account available to anyone else,
  • reproduce or distribute videos, slides, study guides, questions, or source files outside your own use,
  • use the material to deliver training to others, whether paid or unpaid,
  • remove or alter copyright notices, or
  • circumvent or attempt to circumvent access controls on the platform.

Course videos are streamed on the platform and are not provided as downloads. Practice questions are taken on the platform and are not provided as a downloadable file. Where a course includes downloadable material — a slide deck, a study guide, or a starter kit — that is stated on the course page, and the licence above applies to it unchanged.

Source files supplied in a starter kit may be used in your own environment, including at work, and adapted for it. They may not be redistributed as a product or as training material.

5. Prices and Taxes

Prices are shown on the course page and at checkout, in the currency displayed there, and include any applicable value added tax. The final total payable is displayed at checkout before you purchase. The tax rate applied depends on your country of residence and is determined and displayed at checkout.

The tax due on your purchase is calculated, collected, and remitted through the platform's tax handling as configured for this school. Your receipt shows the amount charged and any tax included in it.

6. Payment

Payment is collected at checkout through Teachable Payments, which uses Stripe as its underlying payment processor. The payment methods available to you are shown at checkout. We do not receive or store your card details.

7. Delivery

Access is granted immediately on successful payment. The receipt e-mail and your account's My Courses page are your route to the material.

8. Withdrawal and Refunds

Consumers in the European Union have a statutory right of withdrawal, and every purchase carries a 14-day money-back guarantee. Both are set out in full on the Cancellation and Refunds page, which forms part of these terms.

9. Your Account

You are responsible for keeping your account credentials confidential and for everything done through your account. Tell us at contact@christophernett.com if you believe your account has been used by someone else.

We may suspend or terminate access where an account is used in breach of section 4, in particular where course material is shared or redistributed. Where the breach is remediable and not serious, we will ask you to stop before suspending anything.

10. Content and Availability

Course content is educational material about cybersecurity, cloud, and AI. It is accurate to the best of our knowledge at the time of recording, and the products it covers change frequently. It is general guidance rather than advice for your specific environment, and you remain responsible for evaluating whether a configuration or recommendation fits your systems, your security requirements, and the law that applies to you.

No result is promised. Where a course prepares you for a certification exam, it does not guarantee that you pass it, and we have no influence over exam content, availability, or scoring.

We aim to keep the platform available at all times but do not guarantee uninterrupted availability. Planned maintenance, platform outages, and interruptions outside our control may occur.

11. Liability

We are liable without limitation for intent and gross negligence, for injury to life, body, or health, and under the German Product Liability Act (Produkthaftungsgesetz).

In cases of simple negligence, we are liable only for the breach of essential contractual obligations — obligations whose fulfilment makes the proper performance of this contract possible in the first place and on whose fulfilment you may regularly rely — and only up to the amount of the foreseeable damage typical for this kind of contract.

Any further liability is excluded. Mandatory statutory liability provisions and consumer rights remain unaffected.

12. Changes to These Terms

We may change these terms for future purchases. The version published on this page at the time of your purchase governs that purchase, and a later change does not alter a contract already concluded.

13. Governing Law and Disputes

These terms are governed by the laws of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods (CISG). If you are a consumer, the mandatory consumer protection provisions of the country in which you have your habitual residence remain unaffected.

The European Commission's online dispute resolution platform was discontinued on July 20, 2025. We are neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration board.
