Terms of Service

Last updated: April 2026

These Terms of Service ("Terms") govern your use of the Paceon application and website (collectively, "the Service"), operated by miuustudio ("we," "us," or "our"). By using Paceon, you agree to these Terms. If you do not agree, do not use the Service.

1. Description of Service

Paceon is an AI-powered running training application that generates personalized training plans, adapts them based on your activity data, and provides coaching guidance for distance running events. The Service is available as a mobile application on iOS.

Important: Paceon is a training tool, not a medical service. The training plans, pace recommendations, and coaching notes in Paceon are generated by AI and are for informational purposes only. Always consult a qualified medical professional before starting a new exercise program, especially if you have health concerns.

2. Eligibility

You must be at least 13 years old to use Paceon. By using the Service, you represent that you are 13 or older. If you are under 18, you represent that your parent or guardian has reviewed and agreed to these Terms on your behalf.

3. Account Registration

You must create an account to use Paceon. You are responsible for maintaining the security of your account credentials and for all activity that occurs under your account. Notify us immediately at hello@paceon.fit if you suspect unauthorized use of your account.

You agree to provide accurate, current, and complete information when creating your account and to keep this information updated.

4. Subscription and Billing

Paceon is available through a paid subscription. We offer the following plans:

All subscriptions begin with a 7-day free trial. You will not be charged during the trial period. At the end of the trial, your subscription begins and you are billed for the selected plan.

Subscriptions are managed through Apple's App Store and are subject to Apple's billing terms. Payments are processed by Apple; we do not collect or store payment card information.

Subscription prices may change with prior notice. Price changes take effect at your next renewal date.

5. Cancellation and Refunds

You may cancel your subscription at any time through the App Store (Settings → Apple ID → Subscriptions → Paceon). Cancellation takes effect at the end of your current billing period — you retain access until then.

Refunds are handled by Apple in accordance with their refund policy. We do not process refunds directly. For refund requests, contact Apple Support or submit a request through the App Store.

The Founder Lifetime plan is non-refundable after 14 days from purchase, except where required by applicable law.

6. Acceptable Use

You agree not to:

7. AI-Generated Content

Training plans and coaching notes in Paceon are generated by artificial intelligence (Anthropic Claude API) based on your input data. AI-generated content may contain errors, may not account for individual health conditions, and should not be treated as professional coaching or medical advice.

We do not guarantee that AI-generated plans will improve your performance, prevent injury, or be appropriate for your specific fitness level. Use the plans at your own discretion and risk.

8. Intellectual Property

The Paceon application, brand, design, and all associated content are owned by miuustudio and protected by copyright and intellectual property law. You may not reproduce, distribute, or create derivative works without written permission.

Your personal data (training history, completed workouts, Strava activities) remains yours. We do not claim ownership of your personal data. You grant us a limited license to process your data to provide the Service as described in our Privacy Policy.

9. Disclaimer of Warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT.

10. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, MIUUSTUDIO SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOSS OF DATA, LOSS OF PROFITS, OR PERSONAL INJURY, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE SERVICE, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL LIABILITY TO YOU FOR ALL CLAIMS ARISING FROM OR RELATING TO THE SERVICE SHALL NOT EXCEED THE AMOUNT YOU PAID TO US IN THE 12 MONTHS PRECEDING THE CLAIM.

11. Modifications to the Service

We reserve the right to modify, suspend, or discontinue the Service at any time with or without notice. We will make reasonable efforts to notify you of significant changes via email or in-app notification.

12. Changes to These Terms

We may update these Terms from time to time. We will notify you of material changes by email or in-app notification. Continued use of the Service after changes are posted constitutes your acceptance of the updated Terms.

13. Governing Law

These Terms shall be governed by and construed in accordance with applicable law. Any disputes arising from these Terms shall be resolved through binding arbitration or in the courts of competent jurisdiction. You waive any right to participate in a class action.
