Terms & Conditions

1. Scope

1.1 These General Terms and Conditions (GTC) apply to all contracts concluded between [Your Company] (hereinafter referred to as “Seller”) and the customer (hereinafter referred to as “Customer”) concerning the sale of goods and services in the field of HBOT.

1.2 Customers within the meaning of these GTC are both consumers and entrepreneurs.

  • A consumer is any natural person who enters into a legal transaction for purposes that are predominantly outside their trade, business, or profession (§ 13 German Civil Code – BGB).

  • An entrepreneur is a natural or legal person or a partnership with legal capacity who, when entering into a legal transaction, acts in the exercise of their trade, business, or profession (§ 14 BGB).

2. Conclusion of Contract

2.1 The presentation of goods and services on the Seller’s website does not constitute a legally binding offer but rather an invitation to the Customer to submit a binding order.

2.2 The Customer may submit the offer via the Seller’s online order form. By entering personal data and clicking the “Submit Order” button in the final step of the order process, the Customer submits a legally binding contractual offer regarding the goods and/or services contained in the shopping cart.

2.3 The Seller may accept the Customer’s offer within five days by:

  • sending the Customer a written order confirmation or an order confirmation in text form (fax or email), in which case the receipt of the order confirmation by the Customer is decisive, or

  • delivering the ordered goods to the Customer, in which case the receipt of the goods by the Customer is decisive, or

  • requesting payment from the Customer after the order has been placed.

If the Seller does not accept the Customer’s offer within the aforementioned period, this shall be deemed a rejection of the offer, with the consequence that the Customer is no longer bound by their declaration of intent.

3. Prices and Payment Terms

3.1 The prices stated by the Seller are final prices and include statutory VAT. Any additional delivery and shipping costs will be specified separately in the respective product description.

3.3 Various payment methods are available to the Customer, as specified in the Seller’s online shop.

3.4 If advance payment has been agreed, payment is due immediately after conclusion of the contract.

7.1 The Seller is liable to the Customer in cases of intent and gross negligence in accordance with statutory provisions.

11. Applicable Law

11.1 The law of the Federal Republic of Germany applies to all legal relationships between the parties, excluding the provisions of international sales law (CISG).

11.2 For consumers, this choice of law only applies insofar as the protection afforded by mandatory legal provisions of the state in which the consumer has their habitual residence is not withdrawn.

12. Place of Jurisdiction

12.1 If the Customer is a merchant, a legal entity under public law, or a special fund under public law, the exclusive place of jurisdiction for all disputes arising from this contract is Siegen, Germany.
