Important Notice

Strenvio includes AI-generated coaching. AI output can be wrong, incomplete, or misleading. You are responsible for how you use it. Strenvio is not a medical service and does not replace a qualified professional.

1. Acceptance of these Terms

These Terms & Conditions (“Terms”) are a legally binding agreement between you and Strenvio. By downloading, accessing, or using the App and related services (together, the “Services”), you agree to these Terms. If you do not agree, do not use the Services.

2. Eligibility and minors

You must be at least 13 years old (or the minimum age required by your country) to use the Services. If you are under the age required to enter into a contract where you live, you may use the Services only with a parent/guardian’s consent and supervision.

3. Accounts, security, and account deletion

3.1 Account information

You agree to provide accurate account information and keep it updated. You are responsible for activity on your account and for keeping your login credentials secure.

3.2 Account deletion

If the App allows account creation, the App will also provide a way to request deletion of your account within the App (where required).

4. The Services

Strenvio is a sports and performance tracking and coaching app. Features may include workout/training logs, analytics, insights, and AI-driven coaching recommendations. Some features may require an internet connection and may change over time.

5. AI Coaching and the “Nature of AI”

5.1 Probabilistic output (“hallucinations”)

The AI coaching feature generates text and recommendations based on patterns learned from data. It may produce incorrect, contradictory, incomplete, or nonsensical output. You understand that AI output is not guaranteed to be accurate, safe, or suitable for your situation.

5.2 No human oversight

AI interactions are automated. Unless we explicitly state otherwise, no human coach reviews the AI’s output before it is shown to you.

5.3 User-curated “Long-Term Memory”

If the App offers a “Long-Term Memory” feature, it relies on information you choose to save (for example “Key Points”, “Insights”, or notes). You are solely responsible for what you store, including its accuracy, legality, and relevance. You can remove items you previously saved using the App’s controls (where available).

5.4 Third-party AI providers and data sharing consent

To provide AI coaching, Strenvio may send your prompts, messages, and selected memory items to third-party AI model providers (for example, large language model services). Where required, we will clearly disclose this in the App and obtain your explicit permission before sharing your personal data with third parties, including with third-party AI. You can withdraw your permission by disabling AI features (where available) or by contacting us. Apple’s rules specifically require clear disclosure and explicit permission when sharing personal data with third parties, including with third-party AI.

6. Health, safety, and professional disclaimer

6.1 Not medical advice

The Services are for informational and self-help purposes only and are not medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional before starting or changing any exercise, training, or wellness program, especially if you have any injury, medical condition, or unusual symptoms.

6.2 Stop if something feels wrong

If you feel pain, dizziness, faintness, shortness of breath, chest pain, or anything that feels unsafe, stop immediately and seek professional help.

6.3 Emergencies

Strenvio is not an emergency service. If you believe you are in danger or need urgent help, call local emergency services right away.

7. User content

7.1 Your content

“User Content” includes information you enter or upload (for example training notes, messages, metrics, and feedback). You keep ownership of your User Content as between you and Strenvio.

7.2 License to operate the Services

You grant Strenvio a worldwide, non-exclusive, royalty-free license to host, store, reproduce, process, and display your User Content solely to operate, maintain, improve, and provide the Services (including providing AI features you enable), and as described in our Privacy Policy.

7.3 You are responsible for your content

You represent that you have the rights needed to provide your User Content and that it does not violate law or anyone’s rights.

8. Acceptable use

You agree not to misuse the Services. For example, you must not:

  • Use the Services to generate, request, upload, or share content that is illegal, sexually explicit, abusive, hateful, or violent.
  • Use the Services to exploit or harm minors, or to create sexual content involving minors (zero tolerance).
  • Use the Services to facilitate wrongdoing (for example, fraud, scams, harassment, or illegal activities).
  • Attempt to reverse engineer, disrupt, overload, or bypass security of the Services.
  • Use AI features to generate deceptive content or content intended to mislead others.

9. Reporting, moderation, and enforcement

9.1 In-app reporting

If the App generates or displays AI content, the App will provide an in-app way to report or flag offensive AI-generated content without needing to exit the App. We may use these reports to improve filtering and safety. Google Play specifically requires in-app reporting/flagging for AI-generated content.

9.2 Actions we may take

We may review reports and may remove content, limit features, suspend, or terminate accounts when we believe there is a violation of these Terms, legal requirements, or safety needs. We may do this with or without notice where legally allowed.

10. Paid features, subscriptions, credits, and in-app purchases

10.1 Store billing

If you buy subscriptions, credits, or other paid features through Apple’s App Store or Google Play (“Store Purchases”), the payment is processed by the relevant store, not by Strenvio. Your Store Purchases are subject to the store’s terms and policies.

10.2 Pricing and changes

Prices and availability of paid features can change. If you have an auto-renewing subscription, the store will bill you according to the plan you selected unless you cancel through your store account settings.

10.3 Trials and promos

If we offer trials or promotional pricing, the terms shown at the time of the offer apply. Unless stated otherwise, trials convert to paid plans unless canceled.

10.4 Refunds

Refunds for Store Purchases are handled by Apple or Google under their policies. Strenvio cannot directly issue refunds for Store Purchases.

11. Privacy and data protection

Our Privacy Policy explains what data we collect, how we use it, and how we share it. The Privacy Policy is part of these Terms. You must read it.

If you connect third-party services (for example Apple Health or other integrations), those services are governed by their own terms and policies.

12. Intellectual property

The Services (including software, design, logos, and content provided by Strenvio) are owned by Strenvio or its licensors and are protected by law. You receive a limited, personal, non-transferable, non-exclusive license to use the App for your personal, non-commercial use, subject to these Terms.

13. Feedback

If you send us feedback or suggestions, you grant us permission to use it without restriction or compensation, unless prohibited by law.

14. Termination

You may stop using the Services at any time. We may suspend or terminate your access if you violate these Terms, if we must do so for legal or safety reasons, or if we discontinue the Services (in whole or in part).

15. Disclaimers

15.1 Services provided “as is”

THE SERVICES ARE PROVIDED “AS IS” AND “AS AVAILABLE”. TO THE MAXIMUM EXTENT PERMITTED BY LAW, STRENVIO DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

15.2 AI disclaimer

STRENVIO DOES NOT GUARANTEE THAT AI OUTPUT WILL BE ACCURATE, SAFE, OR USEFUL. YOU ARE RESPONSIBLE FOR HOW YOU USE AI OUTPUT, INCLUDING ANY TRAINING OR HEALTH DECISIONS YOU MAKE BASED ON IT.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, STRENVIO’S TOTAL LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATED TO THE SERVICES WILL NOT EXCEED THE AMOUNT YOU PAID TO STRENVIO FOR THE SERVICES IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM (OR, IF NONE, USD $50 / EUR €50 OR THE MINIMUM AMOUNT ALLOWED BY YOUR LOCAL LAW).

SOME COUNTRIES DO NOT ALLOW CERTAIN LIMITATIONS OF LIABILITY, SO SOME OF THESE LIMITS MAY NOT APPLY TO YOU.

18. Changes to the Services or Terms

We may update the Services and these Terms from time to time. If changes are material, we will provide reasonable notice (for example in-app). By continuing to use the Services after changes take effect, you agree to the updated Terms.

19. Governing law and dispute resolution

These Terms are governed by the laws of Czech Repubic, without regard to conflict-of-law rules. Courts located in Czech Republic will have jurisdiction, unless mandatory consumer protection laws say otherwise.
