Terms of Service
Last updated: April 17, 2026
Welcome to Baller. These Terms of Service ("Terms") form a binding agreement between you and Yaozhuo Sun, an individual developer based in the United States ("we", "us", "our"), the operator of the Baller mobile application ("the App"). By creating an account or using the App, you agree to these Terms. Please read them carefully.
1. Acceptance of Terms
By creating an account or using the App, you agree to be bound by these Terms and by our Privacy Policy. If you do not agree, do not use the App.
2. Description of Service
Baller is an AI-powered basketball training application that provides personalized training plans, drill recommendations, performance tracking, and training reports. The App uses artificial intelligence to generate and adapt training content based on your profile and progress.
3. Account
You must create an account to use the App. You are responsible for maintaining the security of your account credentials. You must provide accurate information and keep it up to date. You may not share your account or transfer it to anyone else.
4. Subscriptions, Free Trial, and Payments
Some features of the App require a paid Baller Pro subscription. Subscriptions are sold and billed through Apple's App Store and are subject to Apple's Standard Terms and Conditions for Apple Media Services.
Pricing (United States): Baller Pro is offered as a monthly subscription at $9.99/month or an annual subscription at $69.99/year. Prices in other regions are shown in the App and may vary by Apple's regional pricing.
Free Trial: New subscribers may be offered a 7-day free trial. If you do not cancel at least 24 hours before the end of the trial period, your subscription will automatically convert to a paid subscription and your Apple ID will be charged the applicable subscription price.
Renewal and Cancellation:
- Payment is charged to your Apple ID account upon confirmation of purchase or at the end of the free trial.
- Subscriptions automatically renew at the end of each billing period unless canceled at least 24 hours before the end of the current period.
- You can manage and cancel subscriptions at any time in your device's Settings → Apple ID → Subscriptions.
- Canceling a subscription stops future renewals; the current paid period will remain active until it expires.
Refunds: All payments are processed by Apple. Refund requests are handled in accordance with Apple's App Store refund policies, which you can request through Apple directly. We do not separately issue refunds.
5. Acceptable Use
You agree not to:
- Use the App for any unlawful purpose
- Attempt to reverse-engineer, decompile, or disassemble the App
- Interfere with or disrupt the App's servers, networks, or AI systems
- Create multiple accounts for abusive purposes, including evading subscription limits
- Resell, redistribute, or commercially exploit the App's content without our written permission
- Use the App in any way that could harm other users or third parties
6. AI-Generated Content
The App uses AI to generate training plans, drill descriptions, and performance reports. While we strive for accuracy, AI-generated content is provided for informational and training-guidance purposes only. It may contain inaccuracies and is not a substitute for professional coaching or medical advice. You are responsible for evaluating the suitability of any AI-generated suggestion before acting on it.
7. Health and Safety Disclaimer
Consult Your Physician. Before beginning any exercise or training program provided through the App, you should consult with a qualified healthcare provider. This is especially important if you have any pre-existing medical conditions, injuries, cardiovascular issues, or physical limitations.
Assumption of Risk. Physical exercise, including basketball training, carries inherent risks of injury. By using the App, you acknowledge and voluntarily assume all risks associated with any training activities you undertake, including but not limited to sprains, fractures, muscle injuries, joint injuries, cardiac events, heat-related illness, and other physical harm.
Not Medical or Professional Coaching Advice. The App provides AI-generated training guidance for informational purposes only. It is not a substitute for professional medical advice, diagnosis, treatment, or certified athletic coaching. You should not disregard professional medical advice or delay seeking it because of information provided by the App.
Your Responsibility. You are solely responsible for monitoring your physical condition during training. Stop immediately if you experience pain, dizziness, shortness of breath, or any discomfort. You are responsible for ensuring that any training environment you use is safe and appropriate.
Minors. The App is intended for users age 13 and older. If you are between the ages of 13 and 18, you must have the consent of a parent or legal guardian before using the training features of the App. Parents and guardians are responsible for supervising minors' use of the App and assume all risks on behalf of their minor children.
No Guarantee of Results. We do not guarantee any specific athletic outcomes, performance improvements, or health benefits from using the App.
8. Intellectual Property
All content, features, and functionality of the App — including but not limited to text, graphics, logos, drill libraries, and software — are the property of Baller and its developer, and are protected by intellectual property laws. You receive a personal, non-exclusive, non-transferable, revocable license to use the App for your personal, non-commercial use, subject to these Terms.
9. Account Deletion
You may delete your account at any time from within the App (Profile → Delete Account). Upon deletion, your personal data and training history will be permanently removed in accordance with our Privacy Policy.
10. Termination
We reserve the right to suspend or terminate your account, with or without notice, if you violate these Terms or engage in conduct that we reasonably determine to be harmful to other users, the App, or us. Upon termination, your right to use the App ceases immediately. Sections that by their nature should survive termination (including disclaimers, limitation of liability, and intellectual property) will survive.
11. Disclaimers and Limitation of Liability
The App is provided "AS IS" and "AS AVAILABLE", without warranties of any kind, express or implied, to the maximum extent permitted by law.
To the maximum extent permitted by law, Baller and its developer shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, goodwill, or other intangible losses, arising out of or in connection with your use of the App. Our total liability for any claim arising out of or relating to these Terms or the App will not exceed the amount you paid us, if any, in the twelve (12) months preceding the event giving rise to the claim, or USD $100, whichever is greater.
12. Changes to Terms
We may update these Terms from time to time. We will notify you of significant changes through the App or by email. Your continued use of the App after the updated Terms take effect constitutes acceptance.
13. Governing Law and Dispute Resolution
These Terms are governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to its conflict-of-laws principles. You agree that any disputes arising out of or relating to these Terms or the App will be resolved exclusively in the state or federal courts located in Delaware, except where applicable consumer protection law gives you the right to bring action in your local jurisdiction.
