1) Scope

1.1 These General Terms and Conditions (hereinafter "GTC") of Sterntal UG (haftungsbeschränkt) (hereinafter "Seller") apply to all contracts for the delivery of goods concluded by a consumer or entrepreneur (hereinafter "Customer") with the Seller regarding the goods presented by the Seller in its online shop. The inclusion of the Customer's own terms and conditions is hereby objected to, unless otherwise agreed.

1.2 A consumer within the meaning of these GTC is any natural person who enters into a legal transaction for purposes that are predominantly neither attributable to their commercial nor their independent professional activity.

1.3 An entrepreneur within the meaning of these GTC is a natural or legal person or a partnership with legal capacity who, when concluding a legal transaction, acts in the exercise of their commercial or independent professional activity.

2) Conclusion of Contract

2.1 The product descriptions contained in the Seller's online shop do not constitute binding offers on the part of the Seller, but serve for the submission of a binding offer by the Customer.

2.2 The Customer can submit the offer via the online order form integrated into the Seller's online shop. In doing so, after having placed the selected goods in the virtual shopping cart and passed through the electronic ordering process, the Customer submits a legally binding contractual offer in relation to the goods contained in the shopping cart by clicking the button that concludes the ordering process.

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 e-mail), whereby the receipt of the order confirmation by the Customer is decisive, or

  • by delivering the ordered goods to the Customer, whereby the receipt of the goods by the Customer is decisive, or

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

If several of the aforementioned alternatives exist, the contract is concluded at the point in time when one of the aforementioned alternatives occurs first. The period for accepting the offer begins on the day after the Customer sends the offer and ends with the expiry of the fifth day following the sending of the offer. 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 result that the Customer is no longer bound by their declaration of intent.

2.4 When selecting a payment method offered by PayPal, payment processing is carried out via the payment service provider PayPal (Europe) S.à r.l. et Cie, S.C.A., 22-24 Boulevard Royal, L-2449 Luxembourg (hereinafter: "PayPal"), subject to the PayPal Terms of Use, viewable at https://www.paypal.com/de/legalhub/paypal/useragreement-full or – if the Customer does not have a PayPal account – subject to the Terms for Payments without a PayPal account, viewable at https://www.paypal.com/de/legalhub/paypal/privacywax-full. If the Customer pays by means of a payment method offered by PayPal that can be selected in the online ordering process, the Seller already declares the acceptance of the Customer's offer at the point in time when the Customer clicks the button that concludes the ordering process.

2.5 When selecting the "Amazon Payments" payment method, payment processing is carried out via the payment service provider Amazon Payments Europe s.c.a., 38 avenue John F. Kennedy, L-1855 Luxembourg (hereinafter: "Amazon"), subject to the Amazon Payments Europe User Agreement, viewable at https://pay.amazon.de/help/201751590. If the Customer selects "Amazon Payments" as the payment method as part of the online ordering process, they also issue a payment order to Amazon by clicking the button that concludes the ordering process. In this case, the Seller already declares the acceptance of the Customer's offer at the point in time when the Customer triggers the payment process by clicking the button that concludes the ordering process.

2.6 When submitting an offer via the Seller's online order form, the text of the contract is stored by the Seller after the conclusion of the contract and transmitted to the Customer in text form (e.g., e-mail, fax, or letter) after the order has been sent. The Seller will not make the text of the contract accessible beyond this.

2.7 Before submitting a binding order via the Seller's online order form, the Customer can identify possible input errors by carefully reading the information displayed on the screen. An effective technical means for better recognition of input errors can be the magnification function of the browser, with the help of which the display on the screen is enlarged. The Customer can correct their entries within the framework of the electronic ordering process using the usual keyboard and mouse functions until they click the button that concludes the ordering process.

2.8 Different languages are available for the conclusion of the contract. The specific language selection is displayed in the online shop.

2.9 Order processing and contact usually take place via e-mail and automated order processing. The Customer must ensure that the e-mail address provided by them for order processing is correct, so that e-mails sent by the Seller can be received at this address. In particular, when using SPAM filters, the Customer must ensure that all e-mails sent by the Seller or by third parties commissioned by the Seller with the order processing can be delivered.

3) Right of Withdrawal

3.1 Consumers are generally entitled to a right of withdrawal.

3.2 Further information on the right of withdrawal can be found in the Seller's cancellation policy.

4) Prices and Payment Terms

4.1 Unless otherwise stated in the Seller's product description, the prices indicated are total prices that include the statutory value-added tax (VAT). Any additional delivery and shipping costs will be stated separately in the respective product description.

4.2 In the case of deliveries to countries outside the European Union, additional costs may arise in individual cases for which the Seller is not responsible and which are to be borne by the Customer. These include, for example, costs for the transfer of money by credit institutions (e.g., transfer fees, exchange rate fees) or import duties or taxes (e.g., customs duties). Such costs may also arise in relation to the money transfer if the delivery is not made to a country outside the European Union, but the Customer makes the payment from a country outside the European Union.

4.3 The payment option(s) will be communicated to the Customer in the Seller's online shop.

4.4 When selecting a payment method offered via the "PayPal" payment service, payment is processed via PayPal, whereby PayPal may also use the services of third-party payment service providers for this purpose. If the Seller also offers payment methods via PayPal in which they make advance payments to the Customer (e.g., purchase on account or installment payment), they assign their payment claim to PayPal or to the payment service provider commissioned by PayPal and specifically named to the Customer. Before accepting the declaration of assignment, PayPal or the payment service provider commissioned by PayPal carries out a credit check using the transmitted customer data. The Seller reserves the right to refuse the Customer the selected payment method in the event of a negative test result. If the selected payment method is permitted, the Customer must pay the invoice amount within the agreed payment period or in the agreed payment intervals. In this case, they can only pay to PayPal or the payment service provider commissioned by PayPal with debt-discharging effect. However, even in the event of the assignment of claims, the Seller remains responsible for general customer inquiries, e.g., regarding goods, delivery time, shipping, returns, complaints, declarations of withdrawal and shipments, or credit notes.

4.5 If the "Sofortüberweisung" (Immediate Transfer) payment method is selected, payment processing is carried out by Klarna Bank AB (publ), Sveavägen 46, 11134 Stockholm, Sweden (hereinafter "Klarna"). In order to be able to pay the invoice amount via "Sofortüberweisung", the Customer must have an online banking account that has been activated for participation in "Sofortüberweisung", identify themselves accordingly during the payment process, and confirm the payment instruction. The payment transaction is carried out immediately afterwards by Klarna and the Customer's bank account is debited. Further information on the "Sofortüberweisung" payment method can be found by the Customer on the Internet at https://www.klarna.com/sofort/.

4.6 When selecting a payment method offered via the "Shopify Payments" payment service, payment processing is carried out by the payment service provider Stripe Payments Europe Ltd., 1 Grand Canal Street Lower, Grand Canal Dock, Dublin, Ireland (hereinafter "Stripe"). The individual payment methods offered via Shopify Payments will be communicated to the Customer in the Seller's online shop. For the processing of payments, Stripe may use other payment services for which special payment terms may apply, to which the Customer may be pointed out separately. Further information on "Shopify Payments" is available on the Internet at https://www.shopify.com/legal/terms-payments-de.

4.7 When selecting a payment method offered via the "Apple Pay" payment service, payment processing is carried out by Apple Distribution International (Apple), Hollyhill Industrial Estate, Hollyhill, Cork, Ireland ("Apple"). The individual payment methods offered via Apple Pay will be communicated to the Customer in the Seller's online shop. For the processing of payments, Apple may use other payment services for which special payment terms may apply, to which the Customer may be pointed out separately. Further information on Apple Pay is available on the Internet at https://www.apple.com/de/apple-pay/.

4.8 When selecting a payment method offered via the "Google Pay" payment service, payment processing is carried out by Google Ireland Limited, Gordon House, 4 Barrow St, Dublin, D04 E5W5, Ireland ("Google"). The individual payment methods offered via Google Pay will be communicated to the Customer in the Seller's online shop. For the processing of payments, Google may use other payment services for which special payment terms may apply, to which the Customer may be pointed out separately. Further information on Google Pay is available on the Internet at https://pay.google.com/intl/de_de/about/.

5) Delivery and Shipping Conditions

5.1 If the Seller offers shipping of the goods, delivery shall be made within the delivery area specified by the Seller to the delivery address specified by the Customer, unless otherwise agreed. In the processing of the transaction, the delivery address specified in the Seller's order processing is decisive. Notwithstanding this, when selecting the payment method PayPal, the delivery address stored by the Customer with PayPal at the time of payment is decisive.

5.2 If the delivery of the goods fails for reasons for which the Customer is responsible, the Customer shall bear the reasonable costs incurred by the Seller as a result. This does not apply with regard to the costs for the outward shipment if the Customer effectively exercises their right of withdrawal. For the return costs, the provision made in the Seller's cancellation policy applies if the Customer effectively exercises the right of withdrawal.

5.3 If the Customer acts as an entrepreneur, the risk of accidental loss and accidental deterioration of the sold goods shall pass to the Customer as soon as the Seller has delivered the item to the freight forwarder, the carrier, or the person or institution otherwise designated to carry out the shipment. If the Customer acts as a consumer, the risk of accidental loss and accidental deterioration of the sold goods generally only passes upon handover of the goods to the Customer or an authorized recipient. Notwithstanding this, the risk of accidental loss and accidental deterioration of the sold goods shall also pass to the Customer in the case of consumers as soon as the Seller has delivered the item to the freight forwarder, the carrier, or the person or institution otherwise designated to carry out the shipment, if the Customer has commissioned the freight forwarder, the carrier, or the person or institution otherwise designated to carry out the shipment and the Seller has not previously named this person or institution to the Customer.

5.4 The Seller reserves the right to withdraw from the contract in the event of incorrect or improper self-delivery. This only applies in the event that the non-delivery is not the responsibility of the Seller and the Seller has concluded a specific covering transaction with the supplier with due diligence. The Seller will make all reasonable efforts to procure the goods. In the event of non-availability or only partial availability of the goods, the Customer will be informed immediately and the consideration will be refunded immediately.

5.5 Self-collection is not possible for logistical reasons.

6) Retention of Title

If the Seller makes advance payments, they reserve the right of ownership of the delivered goods until the purchase price owed has been paid in full.

7) Liability for Defects (Warranty)

Unless otherwise stated in the following provisions, the provisions of statutory liability for defects shall apply. Notwithstanding this, the following applies to contracts for the delivery of goods:

7.1 If the Customer acts as an entrepreneur,

  • the Seller has the choice of the type of supplementary performance;

  • for new goods, the limitation period for defects is one year from delivery of the goods;

  • for used goods, rights for defects are excluded;

  • the limitation period does not start anew if a replacement delivery is made within the framework of liability for defects.

7.2 The liability restrictions and reductions in deadlines regulated above do not apply

  • for claims for damages and reimbursement of expenses by the Customer,

  • in the event that the Seller has fraudulently concealed the defect,

  • for goods that have been used for a building in accordance with their usual use and have caused its defectiveness,

  • for any existing obligation of the Seller to provide updates for digital products, in the case of contracts for the delivery of goods with digital elements.

7.3 In addition, for entrepreneurs, the statutory limitation periods for any existing statutory right of recourse remain unaffected.

7.4 If the Customer acts as a merchant within the meaning of § 1 HGB (German Commercial Code), they are subject to the commercial duty of inspection and notification of defects according to § 377 HGB. If the Customer omits the notification obligations regulated therein, the goods shall be deemed approved.

7.5 If the Customer acts as a consumer, they are asked to complain about delivered goods with obvious transport damage to the deliverer and to inform the Seller of this. If the Customer does not comply with this, this will have no effect on their statutory or contractual claims for defects.

8) Liability

The Seller is liable to the Customer for all contractual, quasi-contractual, and legal claims, including tortious claims for damages and reimbursement of expenses as follows:

8.1 The Seller is liable without limitation for any legal reason

  • in case of intent or gross negligence,

  • in the event of intentional or negligent injury to life, limb, or health,

  • on the basis of a guarantee promise, unless otherwise regulated in this respect,

  • on the basis of mandatory liability such as under the Product Liability Act.

8.2 If the Seller negligently violates an essential contractual obligation, liability is limited to the contract-typical, foreseeable damage, unless there is unlimited liability according to the above section. Essential contractual obligations are obligations that the contract imposes on the Seller according to its content in order to achieve the purpose of the contract, the fulfillment of which enables the proper execution of the contract in the first place and on the observance of which the Customer may regularly rely.

8.3 In all other respects, liability on the part of the Seller is excluded.

8.4 The above liability regulations also apply with regard to the Seller's liability for their vicarious agents and legal representatives.

9) Special Conditions for the Processing of Goods According to Certain Specifications of the Customer

9.1 If, according to the content of the contract, the Seller owes not only the delivery of goods but also the processing of the goods according to certain specifications of the Customer, the Customer must provide the Seller with all content required for processing such as texts, images, or graphics in the file formats, formatting, image, and file sizes specified by the Seller and grant them the necessary rights of use. The Customer is solely responsible for the procurement and acquisition of rights to this content. The Customer declares and assumes responsibility for the fact that they have the right to use the content provided to the Seller. In particular, they shall ensure that no rights of third parties are violated, in particular copyrights, trademark rights, and personal rights.

9.2 The Customer shall indemnify the Seller against claims by third parties which they may assert against the Seller in connection with a violation of their rights through the contractual use of the Customer's content by the Seller. In this case, the Customer also assumes the necessary costs of legal defense including all court and lawyer's fees in the statutory amount. This does not apply if the Customer is not responsible for the legal violation. In the event of a claim by a third party, the Customer is obliged to provide the Seller immediately, truthfully, and completely with all information required for the examination of the claims and a defense.

9.3 The Seller reserves the right to reject processing orders if the content provided by the Customer for this purpose violates legal or official prohibitions or is contrary to public policy. This applies in particular to the provision of anti-constitutional, racist, xenophobic, discriminatory, insulting, youth-endangering, and/or violence-glorifying content.

10) Redemption of Campaign Vouchers

10.1 Vouchers issued by the Seller free of charge as part of promotional campaigns with a certain period of validity and which cannot be purchased by the Customer (hereinafter "Campaign Vouchers") can only be redeemed in the Seller's online shop and only in the specified period.

10.2 Campaign Vouchers can only be redeemed by consumers.

10.3 Individual products may be excluded from the voucher campaign if a corresponding restriction results from the content of the Campaign Voucher.

10.4 Campaign Vouchers can only be redeemed before the ordering process is completed. Subsequent offsetting is not possible.

10.8 The balance of a Campaign Voucher is neither paid out in cash nor does it earn interest.

10.9 The Campaign Voucher will not be refunded if the Customer returns the goods paid for in full or in part with the Campaign Voucher within the scope of their statutory right of withdrawal.

10.10 The Campaign Voucher is only intended for use by the person named on it. Transfer of the Campaign Voucher to third parties is excluded. The Seller is entitled, but not obliged, to check the material entitlement of the respective voucher holder.

11) Applicable Law

The law of the Federal Republic of Germany shall apply to all legal relationships between the parties, excluding the laws on the international purchase of movable goods. In the case of consumers, this choice of law only applies to the extent that the protection granted is not withdrawn by mandatory provisions of the law of the state in which the consumer has their habitual residence.

12) Place of Jurisdiction

If the Customer acts as a merchant, a legal entity under public law, or a special fund under public law with its registered office in the territory of the Federal Republic of Germany, the exclusive place of jurisdiction for all disputes arising from this contract is the Seller's place of business. If the Customer has their registered office outside the territory of the Federal Republic of Germany, the Seller's place of business is the exclusive place of jurisdiction for all disputes arising from this contract if the contract or claims from the contract can be attributed to the professional or commercial activity of the Customer. In the above cases, however, the Seller is in any case entitled to call the court at the Customer's place of business.

13) Alternative Dispute Resolution

The Seller is neither obliged nor willing to participate in a dispute resolution procedure before a consumer arbitration board.
