Terms & Refund Policy
Version 1.6 · Effective November 11, 2026
1. Who you are dealing with
Jan Decher – Azubi-Hilfe Online Lernhilfen & Kurse, Berliner Straße 3, 35315 Homberg (Ohm), Germany. Email: info@passthecalc.com.
2. What is included and what is open now
Your purchase includes over 50 modules. Your email provides access to all your course materials. The Voltage Drop module is also open in your online course at this website.
3. Contract
A contract is formed when your payment is completed at checkout. Payments are processed by Stripe, which emails you a payment receipt.
Purchases are available to customers with a US billing address only. If a payment is made with a billing address outside the United States, we refund it in full automatically and no contract for delivery comes into being. Applicable US sales tax is calculated and collected at checkout by our payment provider based on your billing address.
4. What you buy and how it is delivered
Pass the Calc products are digital content: online videos, worked problems, practice sets and related study material. Nothing is shipped. Immediately after payment, you’ll receive an email with access to all your course materials. Downloaded materials are yours to use without a time limit. There is no future full-release date to wait for. A personal link shown on the confirmation page additionally opens the Voltage Drop module on this website.
5. Your consent
Before you can complete an order you must tick a box with this statement: “I expressly agree that you may begin providing the digital content before the withdrawal period ends. I understand that I lose my right of withdrawal once access has been granted.” An order cannot be placed without this consent. We store the time and wording version of your consent with your order and show it on the confirmation page after payment. The confirmation page repeats this consent and links these terms.
6. Right of withdrawal and when it ends
Consumers in the European Union and in some other countries have a statutory right to withdraw from an online purchase within 14 days. For digital content that is not supplied on a physical medium, this right ends as soon as we begin to perform the contract, provided you have expressly agreed to this, have confirmed that you know you lose the right, and have received our confirmation (§ 356 (5) of the German Civil Code). The right of withdrawal therefore ends when your personal access link is shown on the confirmation page, together with the confirmation of your consent. Until then, you may withdraw by writing to us. For this reason no withdrawal form is provided.
7. All sales are final
This applies to every customer worldwide. Once access has been granted there are no refunds, cancellations or exchanges, regardless of whether you have used the content fully, partly or not at all, and regardless of your exam result.
This does not limit rights that the law does not allow us to exclude. In particular, we will put things right or refund you if you were charged twice, if access was never provided, or if the content is defective and we cannot fix it within a reasonable time. Write to info@passthecalc.com and we will sort it out.
8. Exam results
Pass the Calc is a study aid. We do not promise that you will pass any exam or reach any score. Our problems are written by us; they are not real exam questions and are not issued, reviewed or approved by any licensing agency or exam provider. Exam content, rules and code editions can change. You are responsible for checking the current requirements with your licensing agency and for your own preparation.
9. Your licence
Your purchase gives you a personal, non-transferable right to use the content for your own exam preparation. You may not share your access link, pass the content on, publish it, resell it or use it to train or teach others without our written permission. We may block access in the event of misuse.
10. Payment disputes
If something is wrong with a charge, please contact us first. If a charge is disputed with a bank or card provider, we will submit the order record, including the consent given at checkout, as evidence.
11. Liability
We are fully liable for intent and gross negligence and for injury to life, body or health. For slight negligence we are liable only for breach of essential contractual duties, limited to the foreseeable damage typical for this kind of contract. Otherwise liability is excluded to the extent the law allows.
12. Governing law
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, you keep the protection of the mandatory consumer laws of the country or state where you live. We do not take part in dispute resolution proceedings before a consumer arbitration board.
