Terms of Service for the "LeibFit" app

Last updated: 13 August 2026

This is a courtesy translation of the German "Allgemeine Geschäftsbedingungen (AGB)". In case of any discrepancy, the German version is legally binding, and German law governs the contract as set out in Section 11.

1. Provider and scope

(1) The provider of the "LeibFit" app (the "App") is:

Sebastian Leib, Ahornweg 26a, 68623 Lampertheim, Germany
Email: sebastian.leib@me.com
Small business owner per § 19 UStG (no VAT charged)

(2) These Terms apply to use of the App by consumers ("Users") in Germany, Austria, and Switzerland.

(3) A consumer is any natural person who enters into the transaction for purposes that are predominantly outside their trade, business, or profession.

2. Relationship to Apple

(1) The App is obtained and the subscription concluded exclusively through the Apple App Store. The contracting party for processing the purchase (payment, invoicing, subscription management) is Apple, under Apple's applicable terms.

(2) The subscription is managed and cancelled via the User's Apple ID in device settings (Settings → [Apple ID] → Subscriptions). Payment processing and any refunds are likewise handled through this channel, under Apple's rules.

(3) These Terms govern the relationship between the provider and the User regarding use of the App. They do not create any rights or obligations for Apple.

3. Description of services

(1) LeibFit is a fitness app for home training. Based on the equipment and training profile provided by the User, it generates training suggestions, suggests weights, and documents training progress. Processing takes place locally on the User's device.

(2) With the User's explicit permission, the App can evaluate health and fitness data from Apple Health locally to provide training and recovery guidance.

(3) Not a medical offering / health notice: The App does not replace medical, physiotherapeutic, or other professional advice. The training and recovery guidance is for orientation purposes only and does not constitute a medical diagnosis or treatment recommendation. The User trains at their own responsibility. In case of health concerns or uncertainty, medical advice should be sought before starting training.

(4) The App requires a compatible device and a compatible iOS version (see App Store listing). Certain features require the availability of Apple Intelligence and/or Apple Health on the device.

4. Formation of contract

The contract for the paid subscription is formed when the User confirms the paid subscription as part of the purchase process provided by Apple.

5. Free trial period, prices, and term

(1) After installing, Users can use the App free of charge for 7 days with full functionality. This trial is provided by the provider itself: it requires no subscription, no payment details and no cancellation, and it does not convert into a paid subscription. It starts when the App is first launched on the device and is not transferable. Once the trial ends, Users are free to decide whether to take out a subscription.

(1a) If Apple additionally provides a one-time introductory offer in the App Store (for example a free trial when taking out a subscription), the terms shown during the purchase process apply to that offer; such an offer converts into a paid subscription once it ends, unless it is cancelled via the Apple ID at least 24 hours beforehand.

(2) The subscription is available as either:

a monthly subscription priced at €6.99 per month, or
an annual subscription priced at €44.99 per year.

The prices stated are final prices. As a small business owner, the provider does not charge VAT (§ 19 UStG). For Users outside Germany, Apple may apply different, country-adjusted prices; the price shown in the App Store is decisive.

(3) The subscription automatically renews for the chosen term (one month or one year) unless cancelled via the Apple ID at least 24 hours before the end of the current period. Billing for the renewal is handled via the Apple ID.

(4) Beyond the free trial under paragraph 1, there is no permanently free tier. After the trial period ends without a subscription being taken out, paid features are unavailable; data stored on the device up to that point is retained.

6. Cancellation

The User may cancel the subscription at any time, effective at the end of the current billing period, via subscription management in their Apple ID (Settings → [Apple ID] → Subscriptions). No separate cancellation notice to the provider is required.

7. Right of withdrawal for consumers

Consumers generally have a statutory right of withdrawal. The following withdrawal notice applies.

— Right of withdrawal —

Right of withdrawal: You have the right to withdraw from this contract within fourteen days without giving any reason. The withdrawal period is fourteen days from the day the contract was concluded.

To exercise your right of withdrawal, you must inform us (Sebastian Leib, Ahornweg 26a, 68623 Lampertheim, Germany, sebastian.leib@me.com) of your decision to withdraw from this contract by an unambiguous statement (e.g. by email). To meet the withdrawal deadline, it is sufficient that you send the notice of withdrawal before the withdrawal period expires.

Effects of withdrawal: If you withdraw from this contract, we shall reimburse all payments received from you without undue delay, and no later than fourteen days from the day on which we received notice of your withdrawal. Since payment processing is handled by Apple, any reimbursement follows Apple's terms.

— Premature expiry of the right of withdrawal —

The right of withdrawal expires for a contract for the supply of digital content not supplied on a physical medium if the provider has begun performing the contract after the User has

expressly agreed that performance of the contract may begin before the withdrawal period expires, and
acknowledged that, by giving this agreement, they lose their right of withdrawal once performance begins.

8. User obligations

The User uses the App in compliance with applicable law. The User is solely responsible for the accuracy of the data they enter and for assessing their own physical capacity.

9. Rights of use

The provider grants the User a simple, non-transferable right to use the App for the duration of the contractual relationship, on devices assigned to the User, for the User's own purposes. Any further use, in particular reproduction, modification, or distribution, is not permitted.

10. Liability

(1) The provider is liable without limitation for intent and gross negligence, as well as for injury to life, body, or health.

(2) For simple negligence, the provider is liable only for breach of a material contractual obligation (cardinal obligation) whose fulfillment is essential to the proper performance of the contract and on whose observance the User may regularly rely. In this case, liability is limited to foreseeable damage typical for this type of contract.

(3) Liability is otherwise excluded. Liability under the Product Liability Act remains unaffected.

(4) The App provides training suggestions. For personal injury or property damage arising from a User's own, improper, or health-inappropriate execution of exercises, the provider is liable in accordance with the paragraphs above; see also Section 3(3).

11. Contract language, dispute resolution, applicable law

(1) The contract language is German.

(2) The European Commission provides a platform for online dispute resolution (ODR): https://ec.europa.eu/consumers/odr. The provider is neither obligated nor willing to participate in dispute resolution proceedings before a consumer arbitration board.

(3) The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. For consumers, this choice of law applies only insofar as it does not deprive the consumer of protection granted by mandatory provisions of the law of the country of their habitual residence.

12. Final provisions

Should individual provisions of these Terms be or become invalid, the validity of the remaining provisions shall remain unaffected.
