Terms of Service

Last updated: 4 August 2026

These Terms of Service ("Terms") are a legal agreement between you andKai Qin ("we", "us", "our") governing your use of the Basismobile application ("Basis", the "App", the "Service"). By creating an account or using Basis, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.

Basis was previously called Hybrid. Only the name changed.

1. The Service

Basis provides adaptive training and recovery guidance for athletes, including AI-generated daily plans, log parsing, and a coaching chat. Features may change, and we may add, modify, or discontinue parts of the Service over time.

2. Not medical advice — health disclaimer

Basis is not a medical device and does not provide medical advice. The Service gives general training-load and recovery guidance only. It does not diagnose, treat, cure, or prevent any injury, illness, or condition.

• Consult a qualified healthcare professional before beginning, changing, or continuing any exercise program, especially if you have a medical condition or are recovering from injury.
• Physical training carries inherent risks. You are solely responsible for how you train and for listening to your body.
• If you experience pain, dizziness, chest discomfort, shortness of breath, or any concerning symptom, stop and seek medical attention immediately.
• AI-generated guidance can be incomplete or wrong. Use judgment; do not rely on it as a substitute for professional advice.

3. Eligibility

You must be at least 16 years old to use Basis. By using the Service you represent that you meet this requirement and that the information you provide is accurate.

4. Your account

• You are responsible for maintaining the confidentiality of your account and for all activity under it.
• Keep your account information accurate and current.
• Notify us promptly of any unauthorized use of your account.

5. Acceptable use

You agree not to:

• Use the Service for any unlawful purpose or in violation of these Terms.
• Attempt to reverse-engineer, decompile, disrupt, or gain unauthorized access to the Service or its systems.
• Upload content that is unlawful, infringing, or that you do not have the right to submit.
• Attempt to extract, scrape, or misuse other users' data, or use the Service to build a competing product.
• Interfere with, overload, or circumvent any rate-limiting, security, or cost-control mechanism.
• Create multiple accounts, or delete and re-create an account, in order to obtain more than one free allowance. The free allowance is one per person, and we keep an anonymous marker to enforce this (see Privacy Policy §7.1).
• Use the coach for purposes outside training and recovery guidance (for example general-purpose questions, code, or homework), or attempt to override the coach's instructions through the text you send it.

6. Your content

• You own your content. You retain ownership of the workout text, screenshots, wellness entries, and other data you submit ("Your Content").
• License to operate. You grant us a limited, non-exclusive license to host, process, and transmit Your Content solely to provide and improve the Service to you — including sending the minimum necessary context to our AI processor as described in the Privacy Policy §5.
• Responsibility. You are responsible for Your Content and for having the rights to submit it.

7. AI-generated output

The Service generates plans, summaries, and coaching responses using a third-party AI model. AI output may be inaccurate, incomplete, or unsuitable for your situation. You use it at your own discretion and risk, subject to the health disclaimer in §2.

8. Subscriptions and payments

Some features may require a paid subscription in the future. If and when offered, pricing, billing, renewal, and cancellation terms will be presented at the point of purchase and processed through the applicable app store (Apple App Store or Google Play), subject to that store's terms. (No paid subscription is offered as of the effective date.)

9. Intellectual property

The Service, including its software, design, branding, and content (excluding Your Content), is owned by us or our licensors and is protected by intellectual-property laws. We grant you a limited, personal, non-transferable, revocable license to use the App for its intended purpose. All rights not expressly granted are reserved.

10. Third-party services

The Service relies on third-party providers (see Privacy Policy §6). Your use of the Service may also be subject to the app store's terms. We are not responsible for third-party services outside our control.

11. Termination

You may stop using the Service and delete your account at any time from within the App. We may suspend or terminate your access if you violate these Terms, if required by law, or if we discontinue the Service. Sections that by their nature should survive termination (e.g. §2, §6, §9, §12–§14) will survive.

12. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT ANY GUIDANCE WILL ACHIEVE A PARTICULAR RESULT. Some jurisdictions do not allow certain disclaimers, so some of the above may not apply to you.

13. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, KAI QIN AND HIS SUPPLIERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF DATA, PROFITS, OR GOODWILL, ARISING FROM OR RELATED TO YOUR USE OF (OR INABILITY TO USE) THE SERVICE — INCLUDING ANY PERSONAL INJURY OR HEALTH OUTCOME RELATED TO TRAINING. OUR TOTAL AGGREGATE LIABILITY FOR ANY CLAIM WILL NOT EXCEED THE GREATER OF THE AMOUNT YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM OR USD 50. Some jurisdictions do not allow these limitations, so they may not fully apply to you. Nothing in these Terms limits liability for death or personal injury caused by negligence, for fraud, or for any other liability that cannot be limited under applicable law.

14. Indemnification

You agree to indemnify and hold harmless Kai Qin from claims, damages, and expenses (including reasonable legal fees) arising from your misuse of the Service, your violation of these Terms, or your violation of any law or third-party right.

15. Changes to these Terms

We may update these Terms from time to time. We will revise the "Last updated" date and, for material changes, provide notice in the App. Continued use after an update constitutes acceptance of the revised Terms.

16. Governing law and disputes

These Terms are governed by the laws of Germany, without regard to conflict-of-law rules. Any dispute will be subject to the courts of that jurisdiction, unless applicable law grants you rights to a different venue. If you are a consumer resident in the EU, you keep the protection of the mandatory provisions of the law of your country of residence.

17. Apple App Store additional terms

If you download Basis from the Apple App Store, you acknowledge that these Terms are between you and us, not Apple; that Apple has no obligation to provide support or maintenance for the App; and that Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them. The App must be used in compliance with the Apple Media Services / App Store Terms of Service.
