1. Scope 1.1 These Terms of Service ("Terms") of Northstar Labs LLC ("Seller") apply to all contracts for the delivery of goods entered into between a consumer or business (“Customer”) and the Seller regarding goods presented by the Seller in its online shop. Any terms and conditions of the Customer are hereby objected to, unless otherwise agreed. 1.2 These Terms apply accordingly to contracts for the delivery of vouchers, unless otherwise provided herein. 1.3 For purposes of these Terms, a "consumer" is any natural person entering into a legal transaction for purposes that are predominantly outside their trade, business, or profession. 1.4 For purposes of these Terms, a "business" is any natural or legal person, or partnership with legal capacity, acting in the exercise of their trade, business, or profession when entering into a legal transaction.

2. Formation of Contract The products presented in the Seller's online shop constitute a non-binding invitation to order. By completing the order process (clicking the button that concludes the order), the Customer submits a binding offer to purchase the goods contained in the shopping cart. The contract is concluded once the Seller accepts the order by sending an order confirmation via email or by shipping the goods. The Seller reserves the right to decline orders without stating reasons, for example in cases of unavailability of goods or doubts regarding creditworthiness. Payment is processed via the payment providers offered at checkout in accordance with Section 4. The contract language is English. The text of the contract will be sent to the Customer via email after the order is completed.

3. Return and Refund Rights The Seller voluntarily grants the Customer a 30-day right of return. This right applies exclusively to unused goods in their original condition. To initiate a return, the Customer must contact our customer support at support@doyoo.com within 30 days of receiving the goods. After inspection of the returned goods, the purchase price will be refunded to the original payment method, generally within 10 days of receipt and inspection of the return. Return shipping costs are borne by the Customer, unless stated otherwise. This right of return exists in addition to any mandatory statutory rights applicable at the Customer's place of residence.

4. Prices and Payment Terms 4.1 Unless otherwise stated in the Seller's product description, the prices quoted are total prices. Any sales tax applicable in the United States will, where legally required, be automatically calculated and displayed at checkout based on the Customer's delivery address. Any additional delivery and shipping costs will be stated separately in the respective product description. 4.2 For deliveries outside the United States of America, additional costs may apply 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 money transfers charged by financial institutions (e.g., transfer fees, currency exchange fees) or import duties or taxes (e.g., customs duties). 4.3 The available payment method(s) will be communicated to the Customer in the Seller's online shop. 4.4 If advance payment by bank transfer has been agreed, payment is due immediately upon conclusion of the contract, unless the parties have agreed on a later due date. 4.5 If the Customer selects a payment method offered by PayPal, payment will be processed by the payment service provider PayPal, Inc., 2211 North First Street, San Jose, CA 95131, USA ("PayPal"), subject to the PayPal User Agreement, available at https://www.paypal.com/us/legalhub/paypal/useragreement-full. If the Customer pays using a PayPal-offered payment method selected during the online ordering process, the Seller hereby declares acceptance of the Customer's offer at the time the Customer clicks the button that concludes the order process. 4.6 If the Customer selects a payment method offered through "Shopify Payments," payment will be processed by the payment service provider Stripe, Inc., 354 Oyster Point Blvd, South San Francisco, CA 94080, USA ("Stripe"). The individual payment methods offered through Shopify Payments will be communicated to the Customer in the Seller's online shop. Stripe may use additional payment services to process payments, which may be subject to separate payment terms, of which the Customer will be separately notified where applicable. Further information on "Shopify Payments" is available at https://www.shopify.com/legal/terms-payments-us. 4.7 If the Customer selects payment by credit card via Stripe, the invoice amount is due immediately upon conclusion of the contract. Payment will be processed by the payment service provider Stripe, Inc., 354 Oyster Point Blvd, South San Francisco, CA 94080, USA. Stripe reserves the right to conduct a creditworthiness check and to decline this payment method in the event of a negative result.

5. Delivery and Shipping Terms 5.1 If the Seller offers shipping of the goods, delivery will be made within the delivery area specified by the Seller to the delivery address provided by the Customer, unless otherwise agreed. The delivery address specified during the Seller's order process shall govern the transaction. 5.2 If delivery fails for reasons attributable to the Customer, the Customer shall bear the reasonable costs incurred by the Seller as a result. This does not apply to the cost of the outbound shipment if the Customer effectively exercises their right of return under Section 3. For return shipping costs, the provisions set out in Section 3 apply in the event the Customer effectively exercises their right of return. 5.3 If the Customer is acting as a business, the risk of accidental loss or accidental deterioration of the sold goods passes to the Customer as soon as the Seller has delivered the item to the carrier, freight forwarder, or other person or entity designated to carry out the shipment. If the Customer is acting as a consumer, the risk of accidental loss or accidental deterioration of the sold goods generally passes only upon delivery of the goods to the Customer or an authorized recipient. Notwithstanding the foregoing, the risk of accidental loss or accidental deterioration also passes to a consumer Customer as soon as the Seller has delivered the goods to the carrier, freight forwarder, or other person or entity designated to carry out the shipment, if the Customer has instructed that carrier, freight forwarder, or other person or entity to carry out the shipment and the Seller had not previously named that person or entity to the Customer. 5.4 The Seller reserves the right to withdraw from the contract in the event of incorrect or improper self-supply. This applies only if the Seller is not responsible for the non-delivery and has entered into a corresponding procurement transaction with the supplier with due diligence. The Seller will make all reasonable efforts to procure the goods. In the event of unavailability or only partial availability of the goods, the Customer will be informed without delay and any consideration already paid will be refunded without delay. 5.5 Self-pickup is not possible for logistical reasons.

6. Retention of Title If the Seller performs in advance, the Seller retains title to the delivered goods until full payment of the purchase price owed has been received.

This contract is governed by the laws of the State of Wyoming, USA, excluding the United Nations Convention on Contracts for the International Sale of Goods (CISG) and excluding Wyoming's conflict-of-laws rules. 11.2 Binding Arbitration; Class Action Waiver. Any dispute, claim, or controversy arising out of or relating to these Terms, their breach, termination, enforcement, interpretation, or validity, or to the use of the website or the purchase of goods (collectively, "Disputes") shall be resolved exclusively through final and binding individual arbitration rather than in court, except that either party may bring an individual action in small claims court.

The arbitration will be administered by the American Arbitration Association ("AAA") in accordance with its Consumer Arbitration Rules then in effect, except as modified by this provision.

Each party shall bear its own attorneys' fees and costs in connection with the arbitration, except as otherwise provided under the AAA Consumer Arbitration Rules or applicable law, or as awarded by the arbitrator based on the merits of the claim. 11.5 Exceptions. Notwithstanding the foregoing, either party may bring an individual action in small claims court, and the Seller may seek injunctive or other equitable relief in a court of competent jurisdiction to protect its intellectual property rights, without first engaging in arbitration. 11.6 Venue for Non-Arbitrable Matters. For any matters not subject to arbitration under this Section 11, the exclusive venue shall be the state or federal courts located in Sheridan County, Wyoming, and the Customer consents to the personal jurisdiction of such courts, to the extent permitted by mandatory consumer protection laws applicable at the Customer's place of residence.
