These Terms of Service (“Terms”) govern your access to and use of the 23 Hours platform (“Service”), operated by 2% Endurance (“we,” “our,” or “us”). By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service.
23 Hours is a performance intelligence platform for endurance athletes and coaches. It imports health and fitness data from connected wearable devices (including Whoop, Oura, Garmin, Apple Health, and Strava), analyzes that data, and provides personalized insights including training load scores, nutrition recommendations, sweat and hydration analysis, and race performance predictions.
23 Hours is a tool for informational and performance optimization purposes only. It is not a medical device and does not provide medical advice, diagnosis, or treatment.
You must be at least 13 years old to use the Service. By using the Service you represent that:
You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. Notify us immediately at support@twopercent.life if you suspect unauthorized access.
You may not share your account, create accounts on behalf of others without authorization, or use automated means to create accounts.
By connecting a wearable device or third-party fitness service, you authorize 23 Hours to access and import the health and fitness data made available through that integration. You represent that you have the right to share this data with us.
Health data is sensitive. We treat it accordingly — see our Privacy Policy for full details on how it is stored, protected, and used.
Insights generated from your data — training load scores, nutrition recommendations, race predictions, hydration plans — are provided for informational purposes. They do not constitute medical or professional coaching advice. Always consult a qualified professional before making significant changes to your training, nutrition, or health regimen.
Access to data sync and analytics features requires an active paid membership. Membership fees are billed through Stripe on the cycle shown at sign-up (monthly or annual). All fees are stated in USD and are non-refundable except as required by law or as described below.
We reserve the right to change pricing with 30 days’ notice. Price changes take effect at your next billing cycle. If you do not agree to a price change, you may cancel before it takes effect.
You may cancel your membership at any time from the Membership tab. Access continues until the end of the current billing period.
Coaches may access the data of athletes who have joined via the coach’s invite link. By accepting a coach invite, an athlete grants their coach read access to their health metrics, training data, salt sessions, and race predictions within the 23 Hours platform.
Coaches agree not to use athlete data for any purpose outside of providing coaching services to that athlete, and not to share or export athlete data to third parties without the athlete’s explicit consent.
You agree not to:
The Service, including its design, code, algorithms, and content, is owned by 2% Endurance and protected by copyright, trademark, and other intellectual property laws. These Terms do not grant you any ownership rights in the Service.
Your health and fitness data remains yours. You grant us a limited license to process it for the sole purpose of providing the Service to you. We do not claim ownership of your data.
The Service integrates with third-party platforms including Whoop, Oura, Garmin, Apple Health, and Strava. Your use of those platforms is governed by their own terms of service and privacy policies. We are not responsible for the availability, accuracy, or practices of third-party services.
The Service is provided “as is” and “as available” without warranties of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, or non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or that any data or insights will be accurate or complete.
23 Hours is not a medical device. Nothing in the Service constitutes medical advice. Do not use insights from 23 Hours as a substitute for professional medical, nutritional, or coaching guidance.
To the maximum extent permitted by applicable law, 2% Endurance shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including loss of data, loss of revenue, or personal injury, arising from or related to your use of the Service, even if we have been advised of the possibility of such damages.
Our total liability to you for any claim arising from these Terms or the Service shall not exceed the amount you paid us in the 12 months preceding the claim.
You agree to indemnify and hold harmless 2% Endurance and its officers, employees, and agents from any claims, damages, or expenses (including reasonable legal fees) arising from your use of the Service, your violation of these Terms, or your violation of any third-party rights.
We may suspend or terminate your account at any time if you violate these Terms or engage in conduct that harms the Service or other users. You may delete your account at any time from Profile Settings. Upon termination, your right to use the Service ceases immediately.
We may update these Terms from time to time. When we do, we will update the “Last updated” date above and notify you by email if the changes are material. Continued use of the Service after changes take effect constitutes acceptance of the revised Terms.
These Terms are governed by the laws of the State of Florida, without regard to its conflict of law provisions. Any disputes arising from these Terms or the Service shall be subject to the exclusive jurisdiction of the state and federal courts located in Florida.
