HAC Terms of Use

1. Eligibility

1.1 Age Requirement

The Service is available only to individuals who are at least 18 years of age. By creating an account, you represent and warrant that you are at least 18 years old. If you are under 18, you may not use the Service.

1.2 Verification

We may require verification of your age at our discretion. If we have reason to believe you are under 18, we may suspend or terminate your account and delete any data collected.

2. Description of Service

2.1 Service Overview

HAC is a hormone-informed training and wellness platform designed for female athletes and active women. The Service provides personalized training, recovery, and nutrition insights informed by user-reported data including menstrual cycle tracking, body metrics, sleep quality, mood and energy levels, fueling and hydration habits, and training and workout data. The Service uses a pattern-based algorithm to generate insights based on your individual data over time.

2.2 Third-Party Integrations

The Service may integrate with third-party health and wellness applications, wearable devices, and health data platforms to import data you authorize. The Service may also integrate with third-party hormone testing providers to receive hormone testing data that you choose to share with us, either through manual entry or through an API connection between the third-party provider’s application and ours.

Your use of any third-party application or service is governed by that provider’s own terms and privacy policy. We are not responsible for the products, services, accuracy, or data practices of any third-party provider. HAC does not administer, process, or handle hormone tests.

2.3 Health Platform Data Imports

The Service offers optional integrations with supported health platforms, including Apple Health (iOS) and, where available, Google Health Connect (Android) or other compatible health data sources, through our integration partner (Vital SDK) or direct platform APIs.

• All health platform connections are entirely optional and are not required to use the Service.
• You control which specific data types (such as activity, sleep, or heart rate) the Service can access. The Service only reads categories you explicitly authorize through your device’s health permissions interface.
• HAC does not use imported health platform data for advertising, marketing to third parties, or sale.
• Disconnecting a health platform integration stops all future data imports. Previously imported data remains in your account unless you separately delete it.
• HAC requests access only to the specific health-platform data categories reasonably necessary for the features you have enabled, and only after you grant permission through your device’s health permissions interface.
• HAC’s use of Apple HealthKit data complies with Apple’s HealthKit developer guidelines. HAC’s use of Google Health Connect data complies with Google Play’s health data policies.

2.4 Algorithmic and Coaching-Style Outputs

Insights, recommendations, correlations, and other outputs generated by the Service are informational only and may not be complete, current, or accurate for your individual circumstances. Physical training, nutrition changes, and recovery decisions carry inherent risks. You should use your own judgment and consult a qualified professional when making decisions that affect your health, training, or nutrition.

2.5 Not Medical Advice

IMPORTANT: THE SERVICE IS NOT INTENDED TO PROVIDE MEDICAL ADVICE, DIAGNOSIS, OR TREATMENT.

The Company is not a licensed medical care provider. The Service is designed for informational, educational, and performance optimization purposes only. The recommendations, outputs, and insights provided by the Service are not a substitute for professional medical advice, diagnosis, or treatment. You should always consult with a qualified healthcare provider regarding any medical questions, conditions, or concerns. Never disregard professional medical advice or delay seeking it because of information you have accessed through the Service.

HAC is not a HIPAA-covered entity, and the Service is not a HIPAA-regulated healthcare service. The Service is regulated under applicable federal and state consumer protection, data privacy, and health data laws, unless we expressly state otherwise in connection with a specific partner offering.

2.6 Not a Diagnostic Tool

The Service is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease or medical condition.

2.7 Emergency Situations

In case of a medical emergency, call emergency services immediately. Do not rely on the Service for emergency medical assistance.

3. Account Registration and Security

3.1 Account Creation

To access the Service, you must create an account by providing accurate, current, and complete information. You agree to maintain and promptly update your account information, keep your password secure and confidential, and notify us immediately of any unauthorized access or security breach.

3.2 Account Responsibility

You are responsible for all activities that occur under your account. You agree not to share your account credentials with others.

3.3 Personal Use

The Service is for your personal, non-commercial use unless we agree otherwise in writing.

4. Consent and Data Processing

4.1 General Terms Consent

Before using the Service, you will be asked to affirmatively agree to these Terms and our Privacy Notice by checking a box during account creation.

4.2 Health Data Consent (Required for Use of the Service)

The core value of the Service—personalized, hormone-informed training, recovery, and nutrition insights—depends on processing your health and wellness data, including menstrual cycle data. You will be asked to provide separate, affirmative consent specifically for the collection and processing of this data.

• What this consent covers: Collection and processing of your health data for generating personalized insights, cycle predictions, and training recommendations informed by your menstrual cycle and health patterns.
• What happens if you do not consent: Health data consent is required to complete account creation, because hormone-informed personalization is the product’s core functionality and the Service cannot operate without processing your health data. If you do not wish to consent, you will not be able to create an account or use the Service.
• Withdrawing health data consent: You may withdraw this consent at any time through your account settings. If you withdraw consent:
  • The Service will stop processing your health data for personalization. Because health data processing is required for the Service’s core functionality, withdrawing consent will effectively end your ability to use the Service in any meaningful way.
  • Historical data you previously entered will remain visible to you in read-only form until you delete your account or request deletion.
  • Previously collected identifiable health data will be retained in inactive status unless you request deletion. Upon deletion request, it will be removed from active systems within thirty (30) days and from backups within ninety (90) days, except where retention is required by law.
  • Withdrawal does not affect the lawfulness of processing performed before withdrawal.
  • De-identified data derived from your information before withdrawal and that can no longer identify you is not affected by withdrawal.

4.3 Research Consent (Optional)

You will be given the option to consent to or decline the use of your de-identified data for research purposes. This consent is separate and optional—declining does not affect any feature of the Service. You may change this preference at any time through your account settings. Withdrawal applies to future research activities only.

4.4 Optional Third-Party Import Consent

If you choose to connect third-party applications or devices, you will be asked to authorize each connection and the specific data types to be imported. These connections are entirely optional and can be disconnected at any time. The Service’s core personalized functionality does not require any third-party connections—you can enter all data manually.

4.5 Marketing Consent (Optional)

With your consent, we may send marketing communications. You can opt out at any time via unsubscribe links or account settings.

5. User Data and Privacy

5.1 Privacy Notice

Our collection, use, sharing, and protection of your personal information is described in our Privacy Notice, which is incorporated into these Terms by reference.

5.2 No Sale of Personal Data

We do not and will not sell your personal information to third parties.

5.3 How Your Data Is Used for Personalization and Model Improvement

Your data is used in the following distinct ways:

• Individualized personalization: Your identifiable, account-level data is used to generate your personal insights, predictions, and recommendations. This processing is necessary for the core personalized features.
• General model improvement: De-identified and/or aggregated data is used to improve algorithm accuracy across the user population. Individual account-level data is not used in identifiable form for general model training. De-identified datasets used for internal improvement are access-restricted to authorized personnel only.
• Quality assurance and testing: De-identified data may be used to test new features before release. Access to QA datasets is restricted.
• Product analytics: Usage data (how you interact with the App’s features, not your health data) is used to understand feature adoption and identify improvements.
• Research: Subject to your separate, optional research consent, de-identified and/or aggregated data may be used for scientific research and publication.

De-identified data is never used for advertising, third-party audience building, or any purpose inconsistent with the uses described above. Where any re-identification key or linkage table exists, it is stored separately from de-identified datasets with restricted access controls.

6. Acceptable Use

You agree to use the Service only for lawful purposes and in accordance with these Terms. You agree not to:

• Violate any applicable laws or regulations.
• Infringe upon the rights of others.
• Transmit any harmful, offensive, or inappropriate content.
• Attempt to gain unauthorized access to the Service or related systems.
• Interfere with or disrupt the Service or servers.
• Use automated systems or software to extract data from the Service.
• Reverse engineer, decompile, or disassemble any aspect of the Service.
• Misrepresent your identity or affiliation.
• Use the Service to provide medical advice to others.
• Submit false, misleading, or fraudulent information.
• Transmit viruses, malware, or other malicious code.

7. Intellectual Property Rights

7.1 Company Intellectual Property

The Service, including all content, features, functionality, software, algorithms, models, scoring logic, presentation frameworks, designs, text, graphics, logos, and trademarks, is owned by the Company or our licensors and is protected by copyright, trademark, patent, trade secret, and other intellectual property laws. You are granted a limited, non-exclusive, non-transferable, revocable license to access and use the Service for your personal, non-commercial use.

7.2 Your Data

You retain all rights to the personal data you submit to the Service. By using the Service, you grant us a limited, worldwide, non-exclusive, royalty-free license to use, process, store, and display your data solely for the purposes described in these Terms and the Privacy Notice. This license terminates upon deletion of your account, except with respect to de-identified or aggregated data that can no longer identify you.

7.3 Algorithm and Model Outputs

The underlying models, scoring logic, and presentation frameworks used to generate insights, recommendations, and predictions are the intellectual property of the Company.

However, personalized outputs that are associated with your account and that reveal health-related patterns, predictions, or inferences specific to you may constitute personal information under applicable privacy law. Your privacy rights with respect to those outputs (including access, correction, and deletion) are described in the Privacy Notice. The distinction between intellectual property ownership and privacy rights means that while the Company owns the technology that generates outputs, you retain the privacy rights that applicable law provides to you with respect to personalized outputs linked to your identity.

7.4 Feedback

If you provide us with feedback, suggestions, or ideas, you grant us an unrestricted, perpetual, irrevocable, royalty-free right to use such feedback for any purpose without obligation to you.

8. Disclaimers and Limitations of Liability

8.1 Service Provided “As-Is”

8.2 Health and Wellness Disclaimers

WE MAKE NO REPRESENTATIONS OR WARRANTIES REGARDING THE ACCURACY, RELIABILITY, OR COMPLETENESS OF ANY RECOMMENDATIONS, INSIGHTS, OR DATA PROVIDED THROUGH THE SERVICE.

Nothing in this Section 8 excludes or limits liability for gross negligence, willful misconduct, fraud, or personal injury caused by our negligence, or any other liability that cannot be excluded or limited by applicable law.

9. Indemnification

You agree to defend, indemnify, and hold harmless the Company, its affiliates, licensors, and service providers from and against any claims, liabilities, damages, losses, costs, or fees (including reasonable attorneys’ fees) arising from your violation of these Terms, your use or misuse of the Service, your violation of any third-party rights, or your violation of applicable law.

10. Subscription and Payment Terms

10.1 Subscription Plans

Certain features require a paid subscription. Plans and pricing are displayed in the App prior to purchase.

10.2 Billing and Auto-Renewal

Your subscription will automatically renew at the end of each billing period (monthly or annual, as applicable) at the then-current price unless you cancel before the end of the current billing period. By subscribing, you authorize the applicable platform (Apple App Store or Google Play) to charge your payment method.

10.3 Platform Billing

All subscription purchases and billing are managed through the Apple App Store or Google Play Store. HAC does not directly process or store your payment card details. We receive limited transaction confirmation data from the applicable platform (such as transaction ID, subscription plan, and purchase date) for subscription management and support purposes.

10.4 Cancellation

You may cancel your subscription at any time through your device’s app store subscription settings. Uninstalling the App does not cancel your subscription. Upon cancellation, you retain access to paid features through the end of your current paid billing period.

10.5 Refunds

Refunds for subscription purchases are governed by the refund policies of the Apple App Store or Google Play Store, as applicable. HAC does not independently control or administer refunds for platform purchases. If you have a billing question or believe you were incorrectly charged, we will assist you in resolving the issue with the applicable platform, but the refund decision rests with Apple or Google.

10.6 Free Trials

We may offer free trial periods. If offered, you will be clearly informed of the trial duration, the price after the trial, and how to cancel. At the end of the trial, your subscription automatically converts to a paid subscription unless you cancel through your app store settings before the trial expires.

10.7 Price Changes

We may change subscription prices from time to time. Changes take effect at the start of the next billing period. Pricing may differ by platform or region.

10.8 Platform Account Responsibility

You are responsible for managing your subscription through your Apple App Store or Google Play account. The applicable platform’s terms of service may impose additional billing, cancellation, or refund rules. We encourage you to review the subscription management instructions for your platform.

11. Modifications to Service and Terms

11.1 Service Modifications

We reserve the right to modify, suspend, or discontinue any aspect of the Service at any time. We will use reasonable efforts to provide advance notice of material changes.

11.2 Terms Modifications

We will provide at least thirty (30) days’ advance notice of material changes by posting the updated Terms, updating the “Last Updated” date, and sending you notice through the App or email. If a material change adversely affects your rights, you may terminate your account without penalty within thirty (30) days of notice. Continued use after the effective date constitutes acceptance.

12. Termination

12.1 Termination by You

You may terminate your account at any time using the account deletion feature in the App or by contacting us.

12.2 Termination by Us

We may suspend or terminate your account immediately for breach, fraud, illegal activity, law enforcement requests, or security threats. For other terminations, we will provide at least thirty (30) days’ advance notice.

Upon termination: all licenses and rights under these Terms immediately cease; your personal data will be handled per the Privacy Notice (active deletion within 30 days, backup purge within 90 days); de-identified data used for research, model improvement, or quality assurance may be retained for as long as it remains useful for the stated purposes, subject to periodic review as described in the Privacy Notice; surviving provisions include intellectual property, disclaimers, indemnity, limitations of liability, and dispute resolution.

13. Third-Party Services and Links

The Service may contain links to or integrate with third-party services not owned or controlled by us. We are not responsible for their content, privacy practices, or availability.

14. Dispute Resolution

Before filing any formal dispute, you agree to attempt to resolve it informally by emailing us at emily@teamhac.com. We will attempt resolution through good-faith negotiation within sixty (60) days.

14.3 Binding Arbitration Agreement

IMPORTANT: PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS, INCLUDING YOUR RIGHT TO FILE A LAWSUIT IN COURT AND TO HAVE A JURY TRIAL. BY AGREEING TO THESE TERMS, YOU AND THE COMPANY EACH WAIVE THE RIGHT TO A JURY TRIAL AND THE RIGHT TO PARTICIPATE IN A CLASS ACTION.

If we cannot resolve a dispute informally, you and the Company agree that any dispute arising out of or relating to these Terms or the Service shall be settled by binding arbitration administered by the American Arbitration Association (AAA) in accordance with its Consumer Arbitration Rules, except that:

• You may assert claims in small claims court if your claims qualify; and
• Either party may seek equitable relief in court for intellectual property infringement.

The arbitration will be conducted at a location reasonably convenient to you as determined under the AAA Consumer Arbitration Rules, or by telephone, video conference, or other remote means if you prefer.

14.4 Class Action Waiver

YOU AND THE COMPANY AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING.

14.5 State-Law Limitations

If you reside in a jurisdiction that prohibits mandatory arbitration, class-action waivers, or jury trial waivers for consumers, those provisions will not apply to you to the extent prohibited by your state’s law. All other provisions of this Section 14 remain in effect. Nothing in this section limits your ability to file a complaint with a state attorney general or other regulatory body.
