Terms of Service

Endyr.AI LLC · Effective Date: July 3, 2026 · Last Updated: July 3, 2026 · Version 1.2

These Terms of Service ("Terms") constitute a legally binding agreement between you ("User," "Athlete," or "you") and Endyr.AI LLC ("Endyr," "we," "our," or "us") governing your access to and use of the Endyr platform, mobile applications, websites, AI coaching services, and all related features and content (collectively, the "Services").

Please read these Terms carefully. By creating an account, accessing the Services, or clicking "I Agree," you agree to be bound by these Terms and our Privacy Policy, which is incorporated herein by reference. If you do not agree, do not use the Services.

1. Eligibility and Account Registration

1.1 Age Requirements

You must be at least 18 years of age to create an Endyr account independently. Users between the ages of 13 and 17 may access the Services only with verified parental or legal guardian consent through Endyr's minor athlete onboarding process. Endyr does not knowingly provide Services to individuals under the age of 13.

1.2 Account Accuracy

You agree to provide accurate, current, and complete information during registration and to keep your account information updated. You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account.

1.3 One Account Per User

Each individual may maintain only one personal Endyr account. Affiliate and coaching organization accounts are governed by separate Affiliate tier terms. You may not transfer your account to another person.

1.4 Account Termination by User

You may delete your account at any time through the app settings. Upon deletion, your personal data will be handled in accordance with the data deletion process described in Section 7 of these Terms and our Privacy Policy.

2. Description of Services

2.1 AI-Powered Coaching Platform

Endyr provides an AI-powered athletic coaching platform designed for Masters CrossFit, Hyrox, and functional fitness athletes. These features are produced using Endyr's proprietary methodology together with third-party artificial intelligence services that generate analysis from your wearable data and athlete-provided information. Information about how your data is processed, including by our third-party AI provider, is described in our Privacy Policy.

2.2 Not a Medical Service

THE SERVICES ARE DESIGNED FOR ATHLETIC PERFORMANCE OPTIMIZATION AND GENERAL WELLNESS PURPOSES ONLY. ENDYR IS NOT A HEALTHCARE PROVIDER, MEDICAL DEVICE, OR MEDICAL SERVICE. NOTHING IN THE SERVICES CONSTITUTES MEDICAL ADVICE, DIAGNOSIS, OR TREATMENT. THE AI COACHING RECOMMENDATIONS PROVIDED BY ENDYR ARE NOT A SUBSTITUTE FOR PROFESSIONAL MEDICAL ADVICE, PHYSICAL EXAMINATION, OR THE JUDGMENT OF A LICENSED PHYSICIAN, PHYSICAL THERAPIST, OR OTHER QUALIFIED HEALTHCARE PROFESSIONAL.

You should consult a qualified healthcare professional before beginning any new exercise program, particularly if you have or suspect you have a medical condition, injury, or health concern. If you experience pain, discomfort, or adverse symptoms, stop activity immediately and seek appropriate medical care.

2.3 Service Availability

Endyr makes reasonable efforts to maintain platform availability but does not guarantee uninterrupted access. The Services may be subject to scheduled maintenance, updates, or temporary outages. We will provide advance notice of planned downtime where practicable.

2.4 Service Evolution

Endyr continuously develops the platform. We reserve the right to add, modify, suspend, or discontinue features or Services at any time. We will provide reasonable notice of material changes that affect your use of the platform.

3. Subscription Tiers and Payment

3.1 Subscription Tiers

Endyr offers the following subscription tiers, the features and pricing of which are described on our website and may be updated from time to time:

3.2 Billing and Renewal

Paid subscriptions are billed in advance on a monthly or annual basis as selected at checkout. Subscriptions automatically renew at the end of each billing period unless cancelled before the renewal date. By providing a payment method, you authorize Endyr to charge the applicable subscription fee at each renewal.

3.3 Free Trial

Endyr may offer free trial periods for new subscribers. At the end of the trial period, your subscription will automatically convert to a paid plan unless you cancel before the trial expires. You will be notified in advance of the trial end date.

3.4 Price Changes

Endyr reserves the right to modify subscription pricing. We will provide at least 30 days written notice of price changes via email or in-app notification. Your continued use of the Services after the effective date of a price change constitutes acceptance of the new pricing. If you do not accept the new pricing, you may cancel your subscription before the change takes effect.

3.5 Cancellation

You may cancel your subscription at any time through your account settings or by contacting [email protected]. Cancellation takes effect at the end of the current billing period. Endyr does not provide prorated refunds for partial billing periods, except where required by applicable law.

3.6 Refund Policy

All subscription fees are non-refundable except: (a) as required by applicable law; (b) at Endyr's sole discretion in response to documented service failures; or (c) within 7 days of initial subscription for new subscribers who have not accessed premium features. To request a refund, contact [email protected].

3.7 Payment Disputes

If you believe a charge is incorrect, contact [email protected] within 30 days of the charge. Initiating a chargeback without first contacting Endyr may result in account suspension.

4. Wearable Device Integrations and Health Data

4.1 Third-Party Device Connections

Endyr integrates with third-party wearable devices and health platforms (including but not limited to WHOOP, Oura, Apple Health and Eight Sleep devices). By connecting a third-party device or service, you authorize Endyr to receive and process the data types you explicitly grant access to. Endyr is not responsible for the data practices, accuracy, or availability of third-party platforms.

4.2 Data Accuracy

Wearable device data is subject to the accuracy limitations of the underlying hardware and third-party platforms. Endyr's AI coaching recommendations are informed by this data but are not guaranteed to be error-free. You acknowledge that biometric data from consumer wearables is not clinically validated and should not be used for medical decision-making.

4.3 Meal Photo Processing

Endyr's nutritional logging feature may use photograph analysis to estimate meal composition. Meal photos are processed in real time and immediately deleted from Endyr servers. No meal photograph is retained beyond the processing session. Nutritional estimates derived from photos are approximations only and should not be relied upon for medical dietary management.

4.4 Historical Data Import

When you connect a wearable platform, Endyr may retrieve available historical data from that platform to initialize the fitness algorithm and establish your personal baseline.

4.5 Processing of Your Data

To generate coaching analysis and recommendations, Endyr transmits training and recovery metrics derived from your health data to third-party AI providers that process the data on Endyr's behalf. These providers do not use your data to train AI models and retain it only for a limited period for security and abuse-monitoring purposes before deletion, as described in our Privacy Policy. You provide explicit consent to this processing through the in-app consent flow before any data is sent for analysis. Because AI analysis is a core function of the Services, withdrawing this consent may limit or end your ability to use the Services.

5. Coaches and Coaching Organizations

5.1 Affiliate Agreements

Coaches, gyms, and athletic organizations accessing the Services under the Affiliate tier are subject to a separate Affiliate Agreement in addition to these Terms. In the event of a conflict between these Terms and an executed Affiliate Agreement, the Affiliate Agreement controls with respect to the conflicting provision.

5.2 Coach Access to Athlete Data

Where an athlete is connected to a coach on the platform — whether independently or through a coaching organization — that coach may access the athlete's performance data for the purpose of providing coaching services. Coach access requires the athlete's authorization, granted when the athlete accepts a coach's invitation or connects with a coach during onboarding. Athletes may disable coach access to their performance data at any time through their account settings; while disabled, no coach or coaching organization can view the athlete's performance data. Disabling data sharing does not end the coaching relationship, and messaging between athlete and coach remains available. Coaches agree to use athlete data solely to provide coaching services and not to share, sell, or use athlete data for any other purpose.

5.3 Competitive Intelligence Firewall

Endyr maintains a strict competitive intelligence firewall between affiliated organizations. Athlete data, training metrics, and performance insights belonging to one affiliated organization are not accessible to, and will not be shared with, any other affiliated organization or its coaches, administrators, or members.

5.4 Coach Responsibilities

All coaches and organization administrators are responsible for: obtaining appropriate consent from athletes they onboard; ensuring minor athletes are onboarded through the appropriate parental consent process; using the platform in compliance with applicable professional standards; and maintaining the confidentiality of athlete data.

6. Minor Athletes

6.1 Parental Consent Requirement

Athletes between the ages of 13 and 17 may only use the Services with the affirmative, documented consent of a parent or legal guardian. The parent or guardian must complete the minor athlete consent flow, which includes separate acknowledgment of the types of health data collected and explicit authorization for coach access if applicable.

6.2 Parental Rights and Controls

Parents and legal guardians of minor athletes have the right to: review all data collected about their child; request correction or deletion of their child's data; revoke coach access on behalf of their child; and terminate their child's account at any time. These rights are exercisable by contacting [email protected].

6.3 Age of Majority Transition

When a minor athlete reaches 18, they will be required to independently accept these Terms and the Privacy Policy before continuing to use the Services; parental rights under Section 6.2 end at that point.

6.4 Youth Athlete Coaching Considerations

Endyr's AI coaching recommendations for minor athletes are subject to additional guardrails appropriate for developing bodies. AI-generated training load and recovery recommendations for minor athletes are intended as general guidance only and should be reviewed by a qualified coach or healthcare professional familiar with youth athletic development.

7. Data Export and Deletion

7.1 Your Right to Export

You may request a full export of your personal data at any time through your account settings or by contacting [email protected]. Endyr will deliver your data export within 72 hours. Your export will include all personal data, health data, and AI-generated scores and recommendations that were delivered to you, organized as a structured data package.

7.2 Scope of Export — What Is Included

Your data export includes:

7.3 Scope of Export — What Is Excluded

Your data export includes all personal data and AI-generated outputs delivered to you. It does not include Endyr's proprietary algorithms, scoring methodology, model parameters, weighting coefficients, or population benchmarks. These constitute Endyr's trade secrets and are protected under applicable law. This exclusion is consistent with your rights under the California Consumer Privacy Act (CCPA), Washington My Health MY Data Act, and other applicable privacy laws, which expressly carve out trade secrets from data access and portability obligations. The export provides the what — your scores, recommendations, and biometric data — not the how those outputs were computed.

7.4 Data Deletion Process

You may request deletion of your personal data at any time through your account settings or by contacting [email protected]. Deletion requests are processed as follows:

Step 1 — Export delivery (Days 1–2). If you request deletion together with an export, your data export will be prepared and delivered within 72 hours. The deletion grace window begins upon confirmed export delivery, ensuring you have received your data before permanent deletion proceeds.

Step 2 — Grace window (Days 1–7). Deletion is queued but not executed during the first 7 days following your request (or following export delivery, if requested together). You will receive a confirmation email containing a clearly visible link to cancel the deletion request. This window protects against accidental deletion and allows time to confirm receipt of your export. After 7 days, deletion cannot be reversed.

Step 3 — Deletion processing (Days 8–30). Confirmed deletions are executed across all Endyr systems within 30 days of the original request, including primary databases, backup systems, wearable sync caches, and analytics pipelines. A confirmation email is sent upon completion.

When you submit a deletion request, Endyr will send a confirmation email that reads:

We have received your data deletion request. Your data will be permanently deleted within 30 days. You have 7 days to cancel this request — after that, deletion cannot be reversed. Use the link below to cancel if you change your mind.

7.5 Data Retained After Deletion

The following limited data is retained after a deletion request is fulfilled:

8. Acceptable Use

8.1 Permitted Use

You may use the Services solely: (a) for your own personal athletic coaching and wellness purposes; (b) if you are a coach, for providing coaching services to athletes who have authorized your access; or (c) if you are a coaching organization administrator, for managing your organization's coaches and athletes on the platform.

8.2 Prohibited Conduct

You agree not to:

9. Intellectual Property

9.1 Endyr Ownership

The Services, including the platform, AI algorithms, fitness scoring methodology, model parameters, weighting coefficients, population benchmarks, software, design, text, graphics, and all other content created by Endyr, are owned by Endyr.AI LLC and protected by copyright, trade secret, and other applicable intellectual property laws. These Terms do not grant you any ownership interest in the Services or Endyr's proprietary methodologies.

9.2 Trade Secret Protection

Endyr's AI algorithms, scoring methodology, capacity weighting framework, and related computational methods constitute trade secrets. You acknowledge that access to AI-generated outputs (scores, recommendations, trends) does not grant any right to, or insight into, the underlying methodology. Any attempt to reverse engineer Endyr's algorithms from exported data, platform outputs, or any other means is a material breach of these Terms and may constitute misappropriation of trade secrets under applicable law.

9.3 Limited License to User

Subject to these Terms, Endyr grants you a limited, non-exclusive, non-transferable, revocable license to access and use the Services for your personal, non-commercial use. This license terminates automatically upon termination of your account or these Terms.

9.4 Your Data

You retain ownership of the personal data and health information you provide to Endyr. By using the Services, you grant Endyr a limited license to process, analyze, and use your data to provide the Services as described in the Privacy Policy. Endyr does not claim ownership of your personal data.

9.5 Feedback

If you submit feedback, suggestions, or ideas about the Services, you grant Endyr a perpetual, irrevocable, royalty-free license to use that feedback for any purpose without obligation or compensation to you.

10.4 Essential Basis

You acknowledge that the disclaimers and limitations of liability in this Section reflect a reasonable allocation of risk and are an essential basis of the bargain between you and Endyr. Endyr would not provide the Services on the terms set forth herein without these limitations.

You agree to indemnify, defend, and hold harmless Endyr.AI LLC and its officers, directors, employees, contractors, and agents from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your use of the Services; (b) your violation of these Terms; (c) your violation of any applicable law or the rights of any third party; (d) any data you provide to Endyr that infringes or misappropriates the rights of any third party; or (e) any attempt to reverse engineer or misappropriate Endyr's proprietary algorithms or trade secrets.

12. Dispute Resolution

12.1 Informal Resolution

Before initiating any formal dispute proceeding, you agree to contact Endyr at [email protected] and attempt to resolve the dispute informally. Endyr will attempt to resolve the dispute within 30 days of receiving written notice.

12.2 Binding Arbitration

If informal resolution fails, any dispute, claim, or controversy arising out of or relating to these Terms or the Services shall be resolved by binding individual arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, rather than in court. The arbitration shall be conducted in Hendricks County, Indiana or by videoconference. The arbitrator's decision shall be final and binding.

12.3 Class Action Waiver

YOU AND ENDYR EACH WAIVE THE RIGHT TO A TRIAL BY JURY AND TO PARTICIPATE IN A CLASS ACTION LAWSUIT OR CLASS-WIDE ARBITRATION. ALL DISPUTES MUST BE BROUGHT IN YOUR INDIVIDUAL CAPACITY ONLY.

13.6 Force Majeure

Endyr shall not be liable for any failure or delay in performance resulting from causes beyond its reasonable control, including natural disasters, acts of government, labor disputes, internet outages, or third-party service failures.
