Terms of Use

Last updated: 25 May 2026
Please note: This document is a working draft provided for general informational purposes. It has not yet been reviewed by a qualified lawyer. Before relying on it commercially, Kadvar should have it reviewed by a legal professional familiar with EU and Czech law.

Welcome to Kadvar. These Terms of Use (the "Terms") govern your access to and use of the Kadvar website and application (the "Service"). By creating an account or using the Service, you agree to these Terms. If you do not agree, please do not use the Service.

1. Who we are

Kadvar is an AI-assisted fitness and nutrition planning service operated by an individual sole operator based in the Czech Republic. Contact: support@kadvar.com. (You must add a working contact email before launch — it is legally required.)

2. Eligibility

You must be at least 18 years old to use Kadvar. By using the Service you confirm that you are 18 or older and able to enter into a binding agreement.

3. Not medical advice

Kadvar provides general fitness and nutrition information generated with the assistance of artificial intelligence. It is not medical advice and is not a substitute for professional healthcare. Kadvar does not diagnose, treat, or prevent any disease or condition. Always consult a qualified physician before starting any exercise or nutrition program, especially if you have a health condition, injury, are pregnant, or take medication. See our Health & Fitness Disclaimer for full details.

4. Your account

You are responsible for keeping your login credentials secure and for all activity under your account. You agree to provide accurate information during onboarding, as the quality of your plan depends on it. Notify us promptly of any unauthorised use.

5. Subscriptions, payment and trial

6. Right of withdrawal and refunds (EU consumers)

As a consumer in the EU, you generally have a 14-day right to withdraw from a distance contract. By starting to use a digital service during this period you may be asked to acknowledge that this right can end once the service has been fully provided. Where required by law, refunds will be handled in accordance with applicable EU and Czech consumer protection rules. [This clause in particular should be confirmed by a lawyer, as digital-service withdrawal rules are nuanced.]

7. Acceptable use

You agree not to misuse the Service, including: attempting to access other users' data, reverse-engineering or scraping the Service, reselling or redistributing generated plans commercially, or using the Service for any unlawful purpose.

8. Intellectual property

The Service, its design, and its underlying software are owned by Kadvar. The personalised plans generated for you are provided for your own personal, non-commercial use.

9. AI-generated content

Workout and meal plans are generated using artificial intelligence and may occasionally contain errors, omissions, or unsuitable suggestions. You should use your own judgement, and consult a professional where appropriate, before acting on any plan. Kadvar does not guarantee any particular fitness, weight, or health outcome.

10. Limitation of liability

To the fullest extent permitted by law, Kadvar is not liable for any injury, loss, or damage arising from your use of the Service or reliance on its content, except where such liability cannot be excluded under applicable law. Nothing in these Terms limits liability for death or personal injury caused by negligence where such limitation is prohibited by law.

11. Termination

You may stop using the Service and delete your account at any time. We may suspend or terminate access if you breach these Terms.

12. Changes to these Terms

We may update these Terms from time to time. Material changes will be communicated through the app or by email. Continued use after changes means you accept the updated Terms.

13. Governing law

These Terms are governed by the laws of the Czech Republic, without prejudice to mandatory consumer protections available to you under the law of your country of residence in the EU.
