Terms of Service

You must be at least 16 years old to use the App. By using the App you represent that you meet this age requirement and have the legal capacity to enter into these Terms. If you are using the App on behalf of someone else, you represent that you are authorized to accept these Terms for them.

A9Core is an AI-assisted personal-training and nutrition-guidance app. It generates workout plans, nutrition targets, and coaching suggestions based on the information you provide and, with your permission, data from Apple Health.

The App is a fitness and wellness tool, not a medical device or a healthcare provider. It does not diagnose, treat, cure, or prevent any disease or medical condition.

Read this section carefully.

• The App does not provide medical advice. Content in the App — including workout plans, exercise instructions, calorie and macronutrient targets, and coaching messages — is for general informational and educational purposes only.
• Consult a qualified physician or healthcare professional before starting any exercise or nutrition program, especially if you are pregnant, nursing, elderly, have a pre-existing medical condition or injury, or take medication.
• You assume all risk arising from your use of the App, including the risk of injury from physical exercise. You are solely responsible for exercising within your own limits and stopping any activity that causes pain, dizziness, shortness of breath, or discomfort. Seek immediate medical attention in an emergency.
• We are not responsible for any injury, health condition, or loss that results from your use of, or reliance on, the App.

Plans, recommendations, and coaching in the App are generated in part by automated systems and artificial-intelligence models. AI output can be inaccurate, incomplete, or unsuitable for your circumstances. Treat it as a suggestion, not a directive, and apply your own judgment. We do not warrant the accuracy, completeness, or fitness for any purpose of AI-generated content.

• You may need to create an account to use certain features. You are responsible for maintaining the confidentiality of your credentials and for all activity under your account.
• You agree to provide accurate information (including height, weight, age, and goals). Inaccurate information may produce unsuitable or unsafe recommendations.
• Notify us promptly of any unauthorized use of your account.

Free tier. A limited version of the App is available at no cost.

Trial. New users may receive a 7-day free trial of Pro at no charge and without entering payment information. Unless otherwise stated, the trial does not auto-convert to a paid subscription; when it ends, your account reverts to the free tier until you choose to subscribe.

Pro subscription. Pro features are available through an auto-renewing subscription offered as an in-app purchase:

• Billing is handled by Apple through your App Store account. We do not receive or store your payment-card details.
• The subscription automatically renews at the then-current price unless you cancel at least 24 hours before the end of the current period.
• Manage or cancel your subscription any time in your Apple ID settings (Settings → [your name] → Subscriptions). Deleting the App does not cancel a subscription.
• Current pricing is shown in the App before purchase (for example, [$X.XX / month] or [$XX.XX / year]). Prices may vary by region and may change; we will give notice of changes as required by law and by the App Store.
• Refunds are handled by Apple under the App Store terms. We generally cannot issue refunds directly.

With your permission, the App reads and writes certain data through Apple Health (HealthKit), such as weight, workouts, and heart-rate data. We use this data only to provide the App's features. We do not use Apple Health data for advertising or sell it.

Our collection and use of personal data — including health-related data — is described in our Privacy Policy, which forms part of these Terms. Please read it.

You agree not to:

• use the App for any unlawful purpose or in violation of these Terms;
• reverse-engineer, decompile, or attempt to extract source code, except where permitted by law;
• interfere with or disrupt the App or its servers, or attempt to gain unauthorized access;
• resell, sublicense, or commercially exploit the App without our written permission;
• upload content that is unlawful, harmful, or infringing.

The App, including its software, design, text, graphics, and content (excluding your own data), is owned by us or our licensors and is protected by intellectual-property laws. We grant you a limited, non-exclusive, non-transferable, revocable license to use the App for your personal, non-commercial use, subject to these Terms.

You retain ownership of the data you enter (such as body measurements and workout logs). You grant us a license to use that data as needed to operate and improve the App, as described in the Privacy Policy. You are responsible for the accuracy and legality of the information you provide.

The App relies on third-party services, including Apple (App Store, HealthKit), our cloud/infrastructure provider, and AI model providers. Your use of those services may be subject to their own terms. We are not responsible for third-party services.

The App is provided "as is" and "as available", without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the App will be uninterrupted, error-free, secure, or that its content is accurate or reliable. Some jurisdictions do not allow the exclusion of certain warranties, so some of the above may not apply to you.

To the maximum extent permitted by law, we and our affiliates will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, data, or goodwill, arising out of or relating to your use of (or inability to use) the App. To the maximum extent permitted by law, our total liability for any claim relating to the App will not exceed the greater of the amount you paid us in the [12] months before the claim or [USD 50].

Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law (including liability for death or personal injury caused by negligence, where applicable).

You agree to indemnify and hold us harmless from any claims, damages, losses, and expenses (including reasonable legal fees) arising from your misuse of the App or your breach of these Terms.

We may suspend or terminate your access to the App at any time if you breach these Terms or if we discontinue the App. You may stop using the App at any time. Sections that by their nature should survive termination (including Sections 3, 12, 13, 14, and 17) will survive.

We may update these Terms from time to time. If we make material changes, we will provide notice (for example, in the App or by updating the "Last updated" date). Your continued use of the App after changes take effect constitutes acceptance of the revised Terms.

These Terms are governed by the laws of Vietnam, without regard to its conflict-of-laws rules. Any dispute will be resolved in the competent courts of Da Nang, Vietnam, unless applicable law grants you the right to bring a claim elsewhere. (Confirm this section with a lawyer — where you serve users in other countries, such as the United States or the EU, local consumer-protection law may override the chosen governing law and forum.)
