Legal
Terms of Use
Endurance Bytes LLC · California, USA · Effective: September 18, 2026 · Version 1.1
These Terms of Use (“Terms”) govern your use of this website and the RunCoachSync mobile application and related services (collectively, the “Services”), offered by Endurance Bytes LLC, a California limited liability company (“Company,” “we,” “us”). By accessing the website, downloading, or using the app, you agree to these Terms. If you do not agree, do not use the Services.
These Terms are a general software license and website terms, not a substitute for advice from qualified counsel. We may update them as the business grows.
1. Not medical advice
The Services provide general fitness and training information for educational purposes only. Nothing here is medical advice, diagnosis, treatment, or a substitute for professional judgment by a physician, physical therapist, or other licensed health care provider. The Services do not create a doctor–patient or clinician–patient relationship. Always seek the advice of your physician or other qualified health provider with questions about a medical condition, pregnancy, medications, or your ability to exercise safely. Stop exercising and consult a physician if you experience pain, chest discomfort, dizziness, or other unusual symptoms.
2. Eligibility
You must be old enough to enter a binding contract where you live (typically 18+) to use the Services, or you must have a parent or legal guardian review and accept these Terms on your behalf. If you are under 13, you may not use the Services.
3. Assumption of risk
Physical activity, including running and structured training, involves inherent risks, including injury, overtraining, dehydration, cardiovascular events, and death. You voluntarily choose to participate and assume all risks associated with your use of the Services and any activities you undertake based on their content. You are solely responsible for exercising within your abilities and in a safe environment.
4. No professional relationship
Features labeled as coaching, plans, intelligence, readiness, or similar are software-generated suggestions only. They do not establish a personal training, coaching, or medical relationship with the Company. If you use Coach Mode to share plans with others, you are responsible for your own compliance with applicable laws and professional standards in your jurisdiction.
5. License
Subject to these Terms and the App Store rules of the platform from which you obtained the app, we grant you a limited, non-exclusive, non-transferable, revocable license to use the app for your personal, non-commercial use (or, for Coach Mode, for coaching others in accordance with the app’s intended functionality). The website is provided for information about the Company and its products.
6. Acceptable use
You agree not to misuse the Services, including by attempting to reverse engineer, interfere with security, scrape data at scale, or use the Services in violation of law. You are responsible for your content and for complying with Apple’s terms and HealthKit guidelines.
7. Subscriptions and purchases
Optional subscriptions and in-app purchases are processed by Apple. Pricing, renewal, cancellation, and refunds are governed by Apple’s terms. We do not guarantee uninterrupted or error-free access to paid features. TestFlight builds are pre-release software and may change or stop without notice.
8. Disclaimers
THE SERVICES ARE 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, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICES WILL BE ACCURATE, COMPLETE, RELIABLE, OR SUITABLE FOR YOUR GOALS OR HEALTH STATUS. TRAINING PLANS ARE ESTIMATES. COMPLETING A PLAN DOES NOT GUARANTEE ANY RACE TIME OR PERFORMANCE OUTCOME.
9. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL THE COMPANY OR ITS LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATED TO YOUR USE OF OR INABILITY TO USE THE SERVICES, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE COMPANY’S TOTAL LIABILITY FOR ANY CLAIM ARISING OUT OF THESE TERMS OR THE SERVICES SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE APP OR SUBSCRIPTIONS IN THE TWELVE (12) MONTHS BEFORE THE CLAIM, OR (B) FIFTY U.S. DOLLARS (USD $50), IF NO SUCH PAYMENTS WERE MADE.
Some jurisdictions do not allow certain limitations; in those jurisdictions, our liability is limited to the fullest extent permitted by law.
10. Release and hold harmless
To the fullest extent permitted by law, you release, waive, discharge, and hold harmless the Company and its members, contractors, and affiliates from any and all claims, demands, damages, losses, or causes of action arising out of or related to your use of the Services or any physical activity you perform in connection with them, including claims arising from the negligence of the Company (except where prohibited by law).
11. Indemnification
You agree to indemnify, defend, and hold harmless the Company from any claims, liabilities, damages, losses, and expenses (including reasonable attorneys’ fees) arising from your use of the Services, your violation of these Terms, or your violation of any rights of a third party.
12. Third-party services and device compatibility
The app may integrate with Apple Health, iCloud, and Apple Watch. Your use of those services is subject to Apple’s terms and policies. We are not responsible for third-party services.
Watch sync: Sending structured workouts from the app to a wrist-worn device is supported for Apple Watch only. Other fitness watch brands (for example Garmin, Samsung, Coros, Polar, or Suunto) are not supported for that sync feature as of the date of these Terms, unless and until we announce otherwise in the app or on this website.
13. Website
This website may describe products that are not yet available on the App Store, including TestFlight evaluation. Descriptions are informational. Features can change before and after public release.
14. Changes
We may modify these Terms or the Services. Material changes to the app may require you to accept updated terms in the app before continued use. If you do not agree, you must stop using the Services.
15. Termination
We may suspend or terminate access at any time. You may stop using the Services at any time. Provisions that by their nature should survive (including Sections 1, 3, 8 through 12, and 16) will survive termination.
16. Governing law and disputes
These Terms are governed by the laws of the State of California, United States, without regard to conflict-of-law rules, except where mandatory local law requires otherwise. You agree that the state and federal courts located in California shall have exclusive jurisdiction over disputes arising from these Terms or the Services, where permitted by law.
