Terms of Service

General Terms and Conditions for the app "Zugkraft". Last updated: July 2026.

This is an English translation of the German-language terms governing this Austria-based service; the German version is legally binding. These terms are based on Austrian and EU law.

1. Provider and scope

The provider of the app "Zugkraft" is Lukas Mauracher, Bürgerstraße 22/11, 4300 St. Valentin, Austria (hereinafter "we"). These terms apply to your use of the app as a user. Download and payment processing take place via the Apple App Store; Apple's license terms (Standard EULA) apply in addition.

2. Service

Zugkraft is a training app that provides adaptive training plans, progress tracking, and optional AI-powered features. The app does not replace medical, physiotherapeutic, or nutritional advice. Training content consists of general guideline values. You train at your own responsibility, stop in case of pain or discomfort, and seek medical advice if in doubt. In particular, in cases of pre-existing conditions, injuries, or pregnancy, medical consultation is advised before starting training.

3. Free version and Zugkraft Pro

The app can be used in a free basic version. "Zugkraft Pro" unlocks additional features and is offered as a subscription (monthly or yearly) or as a one-time purchase ("Lifetime"). Current prices are shown to you in the App Store before purchase.

4. Subscription term, renewal, and cancellation

Subscriptions automatically renew for the respective term unless cancelled at least 24 hours before expiry.
Billing is handled through your Apple ID account.
An optional free trial period automatically converts into a paid subscription if not cancelled. Any unused portion of a free trial is forfeited upon purchase.
Cancellation and management of the subscription can be done at any time in your Apple account settings (App Store → Subscriptions). We ourselves cannot cancel Apple subscriptions.
The "Lifetime" purchase is a one-time purchase without renewal.

5. Payment and refunds

Apple is the contractual partner for payment. Refunds are handled exclusively by Apple according to its policies. Please direct related requests to Apple (reportaproblem.apple.com).

6. Right of withdrawal

As a consumer, you have a statutory right of withdrawal. Details and the model withdrawal form can be found in the Right of Withdrawal page.

7. User obligations

You agree not to misuse the app, not to circumvent any protective mechanisms, and not to upload unlawful content (e.g. during plan import).

8. Warranty and liability

Statutory warranty rights apply. We are liable without limitation for intent and gross negligence, as well as for damages resulting from injury to life, body, or health. For slight negligence, we are only liable for breach of material contractual obligations and limited to the foreseeable damage typical for this type of contract. Liability for health consequences arising from your own responsible use of the training content is excluded to the extent permitted by law (see item 2).

9. Availability and changes

We strive for high availability but do not guarantee uninterrupted usability. Individual features (in particular AI and online features) may change or be discontinued. We may amend these terms with reasonable notice where necessary for good cause; for existing subscriptions, changes only take effect at the start of the next term.

10. Governing law and jurisdiction

Austrian law applies, excluding its conflict-of-laws rules and the UN Convention on Contracts for the International Sale of Goods. As a consumer, you continue to enjoy the protection of any mandatory provisions of the law of the country in which you have your habitual residence. Any mandatory consumer venue remains unaffected.
