Terms of Use

1. Who we are and what these terms cover

The website kneepainrecovery.com (the “Website”) and the mobile application “Knee Pain Recovery Workouts” (the “App”) are provided by Kiedrowski Management UG (haftungsbeschränkt), Dresselndorfer Str. 25, 57299 Burbach, Germany (“we”, “us”). Our full company details are in the Legal Notice.

By using the Website or installing and using the App you agree to these terms. If you do not agree, please do not use them. Our Privacy Policy explains how we handle your personal data and is part of these terms.

These terms are written for consumers. Nothing in them limits rights you have under mandatory consumer protection law in the country where you live.

2. Important health notice

The App is not a medical service. It provides general exercise routines and information for people with knee discomfort. It does not diagnose, treat or cure any condition, it is not a medical device, and it is not a substitute for advice from a physician, physiotherapist or other qualified health professional who has examined you.

The plan the App builds for you is based only on the answers you give and on general rules. It cannot take into account injuries, conditions or circumstances you have not told it about, and it cannot examine your knee.

By using the App you confirm and agree that:

• you will consult a physician before starting the exercises if you have had a recent injury or surgery, a diagnosed knee condition, are pregnant, have a cardiovascular condition, or have any other doubt about whether exercise is safe for you;
• you will stop exercising immediately and seek medical advice if you experience sharp or increasing pain, swelling, instability, locking, numbness, dizziness or shortness of breath;
• you exercise at your own risk and are responsible for performing the exercises within your own abilities and in a safe environment;
• in an emergency you will contact your local emergency services, not us.

Information on the Website and in the blog is for general education only and is subject to the same limits.

3. Who can use the App

You must be at least 18 years old to use the App or make a purchase. By using the App you confirm that you are 18 or older.

4. Your account

The App creates an anonymous account for you automatically the first time you open it. No registration is needed. The account and your progress are linked to the device you used. If you delete the App, reset your device or switch to a new one, you may lose access to that account and to your progress; we cannot restore it because we do not know who you are. A purchase can be restored on a new device using “Restore purchases” with the same Apple ID.

You are responsible for your device and for anyone you allow to use the App on it. You can delete your account at any time in the App’s settings.

5. Licence to use the App

We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the App on Apple-branded devices that you own or control, for your own personal, non-commercial use, in accordance with these terms and the App Store rules (the “Usage Rules” in Apple’s Media Services Terms and Conditions). All rights not expressly granted remain with us.

6. Free content and full access

The App is free to download. Some content and features are available free of charge; the full programme is unlocked by a one-time purchase (“Full Access”).

Buying Full Access

Full Access is bought through Apple’s in-app purchase system. The price shown in the App at the time of purchase applies and includes any applicable VAT. Payment is processed by Apple according to your Apple ID payment settings; we never see your payment details. The contract for Full Access is concluded when Apple confirms the purchase.

What you get

Full Access is a single payment, not a subscription. It does not renew and there are no recurring charges. It gives you access to all programme content in the App, including content we add later, for as long as we offer the App (see section 10 for what happens if we discontinue it). Full Access is tied to your Apple ID and can be restored on other devices signed in with the same Apple ID.

Right of withdrawal

If you are a consumer in the EU or EEA you have a statutory right to withdraw from a purchase within 14 days without giving reasons. For digital content such as Full Access, this right expires early if you expressly agree that delivery starts immediately and confirm that you know you thereby lose your right of withdrawal (§ 356(5) BGB). Apple asks for this confirmation during checkout and handles withdrawal and refund requests for purchases made through the App Store. To request a refund, go to reportaproblem.apple.com. Your statutory rights are not affected by this.

7. Acceptable use

You agree not to:

• copy, record, download, redistribute, publicly perform or sell the exercise videos, images, texts or any other content of the App or Website, other than as the App allows;
• reverse engineer, decompile or attempt to extract the source code of the App, except where the law expressly permits it;
• use the App or Website to build a competing product, or use automated tools to scrape them;
• interfere with the operation or security of the App, the Website or our servers, or access them other than through the interfaces we provide;
• use the App in any way that breaks the law or infringes the rights of others.

8. Intellectual property

The App, the Website and all content in them — including exercise videos, images, texts, programme structure, software, logos and the “yourstrength” and “Knee Pain Recovery” names — are owned by us or our licensors and are protected by copyright, trademark and other laws. Except for the licence in section 5, nothing in these terms gives you any right in this content.

If you send us feedback or suggestions, you allow us to use them without any obligation to you.

9. Third-party services

The App relies on services from third parties, including Apple (distribution and payments), Google Firebase (accounts, storage and notifications), RevenueCat (purchase validation) and Crisp (support chat). Your use of those services is also subject to their own terms. The Website and App may link to third-party websites; we are not responsible for their content.

10. Availability, updates and changes

We work to keep the App available and up to date, but we do not promise that it will be available without interruption or error. We may temporarily suspend the App for maintenance, security or technical reasons.

We may update the App, and we may change, add or remove content and features, provided the changes are reasonable for you taking into account our legitimate reasons (such as technical developments, security, legal requirements or improvements to the programme) and do not deprive you of the essential benefit of Full Access. We provide updates required to keep the App in conformity with the contract in accordance with § 327f BGB. To receive them you need to install the updates offered through the App Store and use a supported iOS version.

If we decide to discontinue the App entirely, we will tell you through the App or the Website with reasonable notice, at least three months where possible. Holders of Full Access purchased within the twelve months before discontinuation may request a pro-rata refund from us.

11. Ending your use

You can stop using the App at any time by deleting it and your account. We may suspend or terminate your access if you materially breach these terms, in particular section 7, and do not remedy the breach within a reasonable period after we notify you, or if a remedy is not possible. Your statutory rights in case of termination remain unaffected.

12. Warranty

For consumers, the statutory warranty rights for digital products (§§ 327 et seq. BGB) apply to Full Access. If the App does not conform to the contract, you may be entitled to have the defect remedied, to reduce the price or to terminate the contract, as provided by law.

Free content and features are provided as a courtesy. For these, we are liable only in accordance with section 13.

13. Liability

We are liable without limitation:

• for damage caused intentionally or by gross negligence;
• for injury to life, body or health;
• under the German Product Liability Act (Produkthaftungsgesetz); and
• to the extent we have given a guarantee.

For slight negligence we are liable only for breach of an obligation whose fulfilment is essential for the proper performance of the contract and on whose fulfilment you may regularly rely (a cardinal obligation), and in that case only for the damage that was foreseeable and typical for this type of contract at the time it was concluded.

Beyond this, our liability is excluded. This section also applies to the liability of our employees, representatives and agents.

Please note that the health notice in section 2 describes your own responsibilities when exercising. Nothing in this section limits our liability for injury to life, body or health caused by our fault.

14. Terms required by Apple

Because the App is distributed through the Apple App Store, the following terms apply in addition:

• These terms are between you and us only, not with Apple. We, not Apple, are responsible for the App and its content.
• Apple has no obligation to provide maintenance or support for the App.
• If the App fails to conform to any applicable warranty, you may notify Apple and Apple will refund the purchase price to you. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App.
• We, not Apple, are responsible for addressing any claims by you or a third party relating to the App, including product liability claims, claims that the App fails to conform to legal or regulatory requirements, and claims under consumer protection or similar law.
• If a third party claims that the App infringes its intellectual property rights, we, not Apple, are responsible for the investigation, defence, settlement and discharge of that claim.
• You confirm that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and that you are not on any U.S. Government list of prohibited or restricted parties.
• Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.

15. Governing law and disputes

These terms are governed by the law of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer living in another EU/EEA country, you also benefit from the mandatory consumer protection provisions of that country.

If you have a problem, please contact us first at luca@yourstrength.com — most issues can be resolved quickly. We are neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration board (§ 36 VSBG).

16. Changes to these terms

We may change these terms where necessary for good reason, for example because of changes in the law, in the App’s features or in the services we rely on. We will notify you of changes in the App or on the Website at least four weeks before they take effect. If you do not object before the effective date, the new terms apply; we will point this out specifically in the notification. If you object, you may continue to use the App under the old terms until we terminate in accordance with section 11, and you may delete your account at any time. Changes that reduce the essential benefit of Full Access require your express agreement.

17. Final provisions

If any provision of these terms is invalid, the remaining provisions remain in effect. The English version of these terms is authoritative.
