Use Dyne with clear rules and realistic expectations.

Section 1

Overview and acceptance

These Terms of Service govern your access to and use of Dyne, including the Dyne website, the Dyne mobile app, and related services. Dyne is operated by FASHION ART 3.0 INC, 1680 Michigan Ave Ste 910, Miami Beach, Florida 33139-2550, United States.

By accessing the website, creating an account, downloading the app, or using Dyne, you agree to these Terms and to the Privacy Policy. If you do not agree, do not use Dyne.

Section 2

Eligibility and accounts

You must be at least 16 years old to use Dyne. By using the service, you represent that you meet this minimum age requirement and that you can enter into a binding agreement.

You are responsible for providing accurate account information, keeping your credentials confidential, and for activity that occurs under your account. You may not share your login with another person or let someone else access paid features through your account.

Section 3

Service and app license

Dyne provides training-related digital tools, including workout generation, session logging, recovery signals, progress tracking, gym inventory setup, and account-related features. Some features may be free, limited, or available only with Dyne Pro.

Dyne is a cloud-synchronized service, and substantial account, workout, subscription, and history functionality relies on remote backend systems, including Supabase-backed infrastructure.

Dyne may also use diagnostic and service-protection tooling, including Sentry for app monitoring and, on supported Android protected requests, Google Play Integrity checks. These tools help troubleshoot reliability issues, investigate abuse, and protect the service.

Subject to these Terms, Dyne grants you a limited, personal, non-exclusive, non-transferable, revocable license to use the app and website for your own lawful, non-commercial use.

We may update, improve, limit, or discontinue features at any time. We do not promise that any feature, workflow, or integration will remain available forever.

Section 4

Subscriptions and billing

Dyne currently offers a limited free experience and a paid Dyne Pro subscription. Based on the reviewed app implementation, new users may receive a limited number of free AI-generated workouts before a paywall is reached.

If you purchase Dyne Pro on iPhone or Android, billing, renewal, cancellation, and payment processing are handled through the Apple App Store or Google Play, not directly through this website. Prices, billing intervals, and available offers are shown at the time of purchase.

Subscriptions renew automatically unless canceled through your app-store account settings before the applicable renewal date. Refunds, if any, are subject to the rules of the store through which you purchased and any rights required by applicable law.

For Apple App Store purchases, Apple manages purchase flows and any refund rights available through its platform terms and applicable law. For Google Play purchases, Google Play's refund policy and applicable law apply, and in some cases Google may direct users to contact the developer for help with purchase issues or refunds after the initial platform-managed period.

Section 5

Apple App Store and Google Play terms

If you download Dyne from the Apple App Store or Google Play, you acknowledge that these Terms are between you and FASHION ART 3.0 INC, not with Apple or Google, except to the extent a platform's own terms also apply to your use of the app.

You must comply with all applicable third-party terms when using Dyne, including the terms of your device provider, operating system provider, mobile carrier, and the store from which you downloaded the app.

With respect to the iOS version of Dyne, Apple has no obligation to provide maintenance or support for the app. To the extent permitted by law, FASHION ART 3.0 INC, and not Apple, is responsible for handling app-related claims, including product claims, legal or regulatory compliance claims, and third-party intellectual property claims. If the iOS app fails to conform to any applicable warranty, you may notify Apple, and Apple may refund any purchase price paid for the app itself, if applicable. To the maximum extent permitted by law, Apple will have no other warranty obligation with respect to the app.

Apple and its subsidiaries are third-party beneficiaries of these Terms as they relate to the iOS app, and may enforce those terms against you as a third-party beneficiary. If there is any conflict between these Terms and mandatory store terms, the mandatory store terms control to the extent of the conflict.

Section 6

Health and safety

Dyne is a training tool, not a doctor, therapist, dietitian, physical therapist, or emergency service. The app does not provide medical advice, diagnosis, or treatment. AI-generated workouts, progression suggestions, and recovery signals are informational only.

You are responsible for deciding whether any training plan, exercise, load, repetition target, or rest recommendation is appropriate for your health, fitness, experience, and environment. If you have any medical condition, injury, pain, or concern about whether training is appropriate, consult a qualified professional before using Dyne.

Stop exercising and seek appropriate help if you feel pain, dizziness, shortness of breath, numbness, loss of balance, or any other concerning symptom. You are also responsible for using proper form, checking your equipment, and arranging supervision or spotting where appropriate.

Section 7

Acceptable use

• You may not use Dyne for any unlawful, harmful, fraudulent, or abusive purpose.
• You may not interfere with the service, its monitoring or integrity controls, bypass security, scrape data, or use bots or scripts to access Dyne in unauthorized ways.
• You may not copy, modify, distribute, reverse engineer, or exploit Dyne except as allowed by law.
• You may not attempt to evade trial limits, subscription controls, referral rules, integrity checks, or account restrictions.
• You may not use Dyne in a way that could harm other users, Dyne, or third-party providers.

Dyne and its related software, branding, content, and design are owned by FASHION ART 3.0 INC or its licensors and are protected by applicable intellectual property laws.

Section 8

Termination

You may stop using Dyne at any time. If you have a paid subscription, you must cancel it through the applicable app store to stop future renewals.

We may suspend or terminate access to Dyne if you violate these Terms, misuse the service, fail to pay amounts due through the applicable billing channel, or create risk for Dyne, other users, or our service providers.

If you want to request account deletion or have account-related support needs, contact support@dyne.fitness.

An account deletion request may remove or disable access to your Dyne account and remotely stored data, subject to any information we need to retain for legal compliance, fraud prevention, security, dispute resolution, enforcement, or backup and restoration processes.

Section 9

Disclaimers and liability

To the fullest extent permitted by law, Dyne is provided on an "as is" and "as available" basis. We do not guarantee uninterrupted access, error-free operation, continued feature availability, or that Dyne will achieve any specific training, health, physique, or performance result.

To the fullest extent permitted by law, FASHION ART 3.0 INC will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for loss of profits, revenue, goodwill, data, or business opportunity arising out of or related to Dyne.

To the fullest extent permitted by law, our total liability for claims arising out of or relating to Dyne will not exceed the greater of the amount you paid to Dyne Pro during the 12 months before the claim arose or 100 U.S. dollars. Nothing in these Terms limits liability that cannot be limited under applicable law, including liability for fraud, willful misconduct, or personal injury where such limitations are prohibited.

Section 10

Governing law

These Terms are governed by the laws of the State of Florida, without regard to conflict-of-law rules.

These Terms do not require mandatory arbitration. To the fullest extent permitted by law, disputes arising from or relating to these Terms or Dyne will be resolved exclusively in the state or federal courts located in Miami-Dade County, Florida, unless applicable consumer law requires otherwise.

Section 11

Contact and updates

If you have questions about these Terms, contact support@dyne.fitness.

We may update these Terms from time to time. When we do, we will post the updated version on this page and update the "Last updated" date above. Your continued use of Dyne after the updated Terms take effect means you accept the revised Terms.
