1) Scope and Applicability

These Terms of Service ("Terms") govern all relationships between Mane Biotech GmbH, operating under the brand niostem, and users of our websites, online stores, mobile applications, and devices (collectively, the "Services"). By using our Services, you agree to be bound by these Terms.

These Terms apply to both consumers and business customers, unless otherwise specified. In the event of conflict, mandatory consumer protection laws shall prevail.


2) Contract Formation

(1) The presentation of products in our online store does not constitute a legally binding offer but an invitation to order. By placing an order, you submit a binding offer to purchase the goods. The contract is concluded once we confirm your order by email.

(2) For app use, the contract is formed when you download the app and accept these Terms upon registration.

(3) Contracts are concluded in English. German law applies as outlined in Section 12.


3) Product Information and Pricing

(1) Product descriptions, specifications, and prices are subject to change without notice but will not affect existing orders.

(2) All prices include VAT (where applicable) and are displayed in euros (€).

4) Payment, Delivery, and Transfer of Risk

(1) Payments may be made via Stripe, PayPal, Klarna, Mollie, Apple Pay, or Google Pay.

(2) Delivery is handled by our logistics partners (DHL, UPS, FedEx, Hermes). Delivery times are indicated during checkout.

(3) Risk of loss passes to you upon delivery to your address. For business customers, the risk passes upon handover to the carrier.

You have the right to withdraw from this contract within 14 days without giving any reason.

The withdrawal period is 14 days from the day on which you or a third party designated by you (other than the carrier) takes possession of the goods.
