4.3 If the User carries out the order process via the MATS App, the User requires an account with “Google Play” to use the “Google Pay” payment system of Google Ireland Limited, Gordon House, 4 Barrow St, Dublin, D04 E5W5, Ireland (hereinafter “Google“) or an account in the “App Store” to use the “Apple Pay” payment system of Apple Distribution International, Hollyhill Industrial Estate, Cork, T23 YK84, Ireland (hereinafter “Apple“) in order to select a payment method and complete the order process.  Via the respective payment system, the User can select a payment method or payment service as part of the ordering process.

For this purpose, a forwarding to Google or Apple takes place.

Notwithstanding the foregoing, the training plan must be of such a nature that, from the point of view of an averagely informed and reasonable third party without any particular prior or specialized knowledge in the medical or athletic field, compliance with the training plan does not lead to permanent health impairments for a physically healthy athlete/athlete that go beyond the actual training load.

§ 15 Final provisions

15.1 Contracts between the Provider and the User under these GTC shall be governed by the laws of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods (CISG). In the case of consumers, this choice of law shall only apply to the extent that the protection granted by mandatory provisions of the law of the country of the consumer’s habitual residence is not thereby withdrawn (favorability principle).

15.2 The place of performance for all services arising from the contracts concluded between the Provider and the User as well as the place of jurisdiction shall be the Provider’s place of business, insofar as the User is not a consumer within the meaning of Section 13 of the BGB, but a merchant, a legal entity under public law or a special fund under public law. The same shall apply if the customer does not have a general place of jurisdiction in the Federal Republic of Germany or the European Union or if the customer’s place of residence or habitual abode is unknown at the time the action is brought. The right to also call upon the court at another legal place of jurisdiction remains unaffected by this.

15.3 Should individual provisions in these GTC be or become invalid and/or contradict the statutory regulations, this shall not affect the validity of the provisions in these Terms of Use in other respects. The ineffective provision shall be replaced by the contracting parties by mutual agreement with a provision that comes as close as possible to the economic purpose of the ineffective provision in a legally effective manner. The above provision shall apply mutatis mutandis in the event of loopholes.

15.4 The EU Commission provides an Internet platform for online dispute resolution (“ODR platform”) at This platform serves as a contact point for the out-of-court settlement of such disputes arising from online purchase contracts.
