In short: Splitwerk is a training app, not medical advice. You subscribe via Apple; your subscription renews automatically until you cancel it in your Apple ID settings. Refunds are handled by Apple. The text below is what counts.
1. Provider and scope
(1) The Splitwerk app (the "App") is provided by Nick Illig, Unterm Grasweg 57, 79379 Müllheim, Germany ("we", "us"). Contact: support@splitwerk.app.
(2) These Terms govern your use of the App. Apple's Licensed Application End User License Agreement also applies (Apple Standard EULA). Conflicting terms of users do not apply.
(3) The App is intended for consumers for private use.
2. Services
(1) The App helps you prepare for hybrid fitness races in the 8 × 1 km run plus 8 stations format. In particular it offers: a finish-time prediction with a range, an analysis of the segments with the greatest potential for improvement ("time sinks"), an adaptive training plan, a workout player with timer and voice cues, a pacing plan, a doubles planner and a technique library. The current scope is described in the App Store listing and in the App itself.
(2) Predictions, target times and recommendations are model-based estimates using your inputs. They are not a promise of any particular result.
(3) Without a subscription only selected features are available (e.g. your prediction). Full access ("Pro") requires a subscription.
(4) Splitwerk is independent and not affiliated with any organiser of hybrid fitness races or their trademarks.
3. Contract via the App Store
(1) Downloads and subscriptions are handled exclusively via the Apple App Store. Apple (in the EU: Apple Distribution International Ltd., Ireland) processes purchase and payment under the App Store terms. We are responsible for the content and services of the App.
(2) A subscription contract is concluded when you confirm the purchase in Apple's payment dialog.
4. Subscriptions, free trial and prices
(1) We offer the following subscriptions (prices for Germany, incl. VAT):
- Annual: €79.99 per year, with a 7-day free trial,
- Monthly: €14.99 per month, without a trial.
The prices shown in the App Store before purchase apply; they may differ in other countries (e.g. UK: £69.99 per year / £12.99 per month). We may offer limited-time or one-time special offers (e.g. a discounted annual plan); the conditions shown in the offer then apply.
(2) Free trial: the trial is available once per Apple ID. Unless you cancel at least 24 hours before it ends, it automatically converts into the paid annual subscription and the annual price is charged to your Apple ID.
(3) Renewal: purchase, term and renewal of your subscription are governed by the terms of Apple's App Store. Under these, a subscription renews automatically for the chosen term (one year or one month) unless you cancel at least 24 hours before it ends; Apple charges the renewal to your Apple ID within the 24 hours before the end of the current period.
(4) Price changes for existing subscriptions happen only in line with App Store rules. Apple will inform you in advance; where required, a higher price applies only after you agree.
5. Cancellation
(1) You can cancel your subscription at any time, effective at the end of the current trial or period – on your iPhone under Settings → [your name] → Subscriptions → Splitwerk → Cancel Subscription, or via your Apple ID's subscription management. Cancel at least 24 hours before the end of the period to avoid renewal.
(2) Deleting the App does not cancel a subscription.
(3) When your subscription ends, Pro features are no longer available. Data stored locally remains on your device until you delete it.
(4) The right to terminate for good cause remains unaffected.
6. Right of withdrawal and refunds
(1) Consumers have a statutory right of withdrawal when purchasing digital content and services. As purchase and payment are handled by Apple, information about, exercise and processing of withdrawal follow the App Store terms. Apple provides the withdrawal information.
(2) Refunds can only be requested from Apple, e.g. at reportaproblem.apple.com. We have no access to payments and cannot issue refunds ourselves.
7. Health notice – no medical advice
(1) The App does not replace medical advice, diagnosis or treatment, nor personal supervision by qualified coaches. Content and training plans are general training recommendations.
(2) Get a medical check-up before starting intense training, especially if you have pre-existing conditions, symptoms or injuries, are pregnant, take medication, or answered "yes" to any question in the App's health check.
(3) You train at your own risk. Listen to your body and stop immediately if you notice pain, dizziness, shortness of breath or other unusual symptoms. Make sure you have a safe training environment, suitable equipment and correct technique.
8. Your obligations
(1) Enter your information to the best of your knowledge; the quality of predictions and plans depends on it.
(2) You may use the App only in accordance with these Terms and the Apple Standard EULA. In particular, you may not circumvent technical protection measures, decompile the App (except where permitted by law) or commercially redistribute or copy its content.
9. Licence and intellectual property
(1) The App and its content (including text, training plans, graphics and software) are protected by copyright. You receive a simple, non-transferable right to use the App for private purposes – for Pro features, for the duration of your subscription.
(2) You may share result cards created with the App for private purposes, including on social networks.
10. Statutory rights and updates
(1) Statutory warranty rights apply, in particular the rules on contracts for digital products (Sections 327 et seq. of the German Civil Code, BGB). We provide updates necessary to keep the App in conformity (Section 327f BGB).
(2) The App's core features work offline. Some features (e.g. purchasing and restoring purchases) require an internet connection.
11. Liability
(1) We are liable without limitation for intent and gross negligence, for injury to life, body or health, under the German Product Liability Act and to the extent of any guarantee we have given.
(2) For slightly negligent breaches of an essential contractual obligation, our liability is limited to the foreseeable damage typical for the contract. Essential obligations are those whose fulfilment makes proper performance of the contract possible in the first place and on whose compliance you may regularly rely.
(3) Otherwise, liability for slight negligence is excluded.
(4) These limitations also apply in favour of our vicarious agents. Statutory warranty rights (section 10) remain unaffected.
12. Changes to these Terms
We may change these Terms for the future, e.g. when we add features or the law changes. We will inform you of changes in the App in good time. Changes that affect essential terms of your existing subscription (e.g. scope of service or price) to your disadvantage only take effect with your consent.
13. Governing law, dispute resolution
(1) German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer habitually resident in another country, the mandatory consumer protection provisions of that country remain unaffected.
(2) We are neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration board. If you have questions or problems, just email support@splitwerk.app.
(3) If individual provisions are invalid, the rest of the contract remains valid; Section 306 BGB applies.
