Terms and Conditions

1. Scope & Provider

These Terms and Conditions apply to all contracts for the purchase of digital goods (eBooks and comparable digital content) via this website. The provider is David Vaupel, named in the legal notice (brand “M.d.Ä.”).

2. Subject Matter of the Contract

The goods sold are digital content provided as files in the formats EPUB and PDF. No physical data carrier is delivered. The files can be opened with common reading software and reading devices for EPUB and PDF; they carry no technical copy protection. They carry a personal identifier (see no. 6).

3. Ordering Process and Conclusion of Contract

The order proceeds in these steps:

1. Choose the edition in the Kontor and, if desired, add a dedication or a gift.
2. Enter the email address for delivery and, for a dedication or a gift, the details requested there.
3. In the payment step, tick the box on immediate delivery (see no. 7), choose the payment method and enter the payment details.
4. The button “Order with obligation to pay” places the binding order.

The presentation of the works in the Kontor is a binding offer. It is accepted with the button “Order with obligation to pay”; the purchase contract is thereby concluded. If the payment service declines the payment or it is not carried out, no delivery takes place.

Entries can be changed at any time until the order is sent: via “Back” in the payment step, by overwriting the fields or by closing the page. Before sending, the edition chosen and the total price are shown directly above the order button.

German and English are available for concluding the contract. In the event of discrepancies the German version prevails. The text of the contract is not stored as a separate document. The order data is stored; it is sent by email together with the invoice, these Terms and the withdrawal instructions. The Terms and the withdrawal instructions are also permanently available on this website and can be saved and printed. The provider is not subject to any particular code of conduct.

4. Prices & Payment

All prices are final prices and include statutory value added tax. There are no shipping costs. Payment is made via the payment methods offered during the ordering process and falls due with the order.

5. Provision

Immediately after receipt of payment, the files (EPUB and PDF) are sent by email. In addition, a personal download link is provided, which is valid for 30 days. For payment methods where receipt of payment is confirmed only later, the files are provided upon that confirmation.

6. Rights of Use

With the purchase, a simple, non-transferable right of personal use is granted. Passing on, reproduction for distribution, or resale is not permitted. Each copy is marked with a personal identifier for traceability.

In the case of a gift purchase, the buyer is the contractual partner (payment and declaration of withdrawal); the gifted person is the beneficiary and receives the files. The personal identifier is then issued to the recipient's address. An optionally booked dedication is included in both formats.

7. Right of Withdrawal

Consumers have a statutory right of withdrawal; the withdrawal instructions apply. For digital content that is not supplied on a tangible medium, the right of withdrawal expires if provision of the files has begun after express consent was given to begin before the withdrawal period has expired, knowledge of the loss of the right of withdrawal was acknowledged, and a confirmation of the contract containing these declarations has been provided (section 356 (6) no. 2 of the German Civil Code, BGB). Consent and acknowledgement are obtained in the payment step by a separate tick box.

A withdrawal can also be declared via the function “Withdraw from contract” on this website.

8. Rights in the Event of Defects

The statutory rights in the event of defects in digital products apply. The statutory obligation to provide updates remains unaffected.

9. Liability

The provider is liable without limitation for intent and gross negligence, for injury to life, body or health, under the German Product Liability Act, and where a guarantee has been given or a defect has been fraudulently concealed.

In the case of slight negligence, the provider is liable only for the breach of an essential contractual obligation, that is an obligation whose fulfilment makes the performance of the contract possible in the first place and on whose observance one may regularly rely. In this case liability is limited to the foreseeable damage typical for the contract.

10. Dispute Resolution

There is neither willingness nor obligation to take part in dispute resolution proceedings before a consumer arbitration board.

11. Final Provisions

The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. Towards consumers this choice of law applies only insofar as it does not withdraw the protection granted by mandatory provisions of the state in which the consumer has their habitual residence.

Should any provision be invalid, the validity of the remaining provisions shall remain unaffected.
