Terms and Conditions
1. Scope
These Terms and Conditions apply to all contracts concluded between Marvin Schürhaus (hereinafter the "Provider") and consumers (hereinafter the "Customer") for the direct sale of goods or services by the Provider.
The majority of Marvin Schürhaus's offering – in particular products within The 1:1 Diet by Cambridge Weight Plan and PortionIQ products – is sold through the Cambridge Weight Plan's 1:1 app operated by that provider, where that provider's own terms and conditions apply. These Terms only apply where the Provider, as an exception, concludes a contract directly with the Customer outside the 1:1 app, for example in connection with coaching services or a direct sale.
2. Formation of Contract
The presentation of services and products on the website does not constitute a binding offer, but a non-binding invitation for the Customer to submit an offer. The contract is formed when the Provider expressly accepts the Customer's order or booking (e.g. by email or appointment confirmation).
3. Prices and Payment Terms
The prices stated on the website or in the respective offer at the time of ordering apply. All prices are final prices. Marvin Schürhaus applies the German small business exemption (§ 19 UStG); no VAT is therefore stated.
Payment can be made, at the Customer's choice, in cash, by bank transfer, by SumUp card payment, or via a SumUp payment link sent by the Provider. For payment by bank transfer, unless otherwise agreed, the invoice amount is due within 14 days of invoicing without deduction; for the other payment methods, payment is made immediately upon ordering or handover of the goods.
4. Delivery
In-stock items are shipped within 1–3 business days of receipt of payment. For items that need to be specially ordered, delivery — where delivery is possible — may take up to three weeks. Delivery is made to the address provided by the Customer within Germany. For coaching and consulting services, no physical delivery takes place; the service is provided online at the agreed appointment.
5. Retention of Title
Delivered goods remain the property of the Provider until paid in full.
6. Right of Withdrawal
Consumers have a statutory right of withdrawal. Details can be found in the Right of Withdrawal notice.
7. Warranty
Statutory warranty rights apply. Should delivered goods be defective, the Customer is first entitled to subsequent performance. Further claims (rescission, price reduction, damages) are governed by statutory provisions.
8. Liability
The Provider is liable without limitation for intent and gross negligence, as well as under the Product Liability Act. For slight negligence, the Provider is only liable for breach of a material contractual obligation (cardinal obligation), the fulfilment of which is essential for the proper performance of the contract and on whose compliance the Customer may regularly rely; in this case, liability is limited to the foreseeable damage typical for the type of contract. Liability for damage resulting from injury to life, body, or health remains unaffected.
No substitute for medical advice:
The Provider's services constitute nutritional guidance and do not replace medical diagnosis, treatment, or advice. If you have health concerns, or before starting any dietary change, consulting a physician is recommended.
9. Applicable Law and Jurisdiction
The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. Mandatory consumer-protection provisions of the country in which the Customer has their habitual residence remain unaffected.
10. Final Provisions
Should individual provisions of these Terms be or become invalid, the validity of the remaining provisions shall remain unaffected.
