Effective Date: August 2, 2026

Developer: Denys Mylymko

App: Tonnage: Workout Tracker Gym

Welcome to Tonnage: Workout Tracker Gym (the “App” or “Service”), developed and operated by Denys Mylymko (“we,” “our,” or “us”). By downloading or using the App, you agree to these Terms of Use (the “Terms”). Please read them carefully.

If you do not agree with these Terms, please stop using the App immediately.

1. License to Use

We grant you a limited, non-exclusive, non-transferable, and non-sublicensable license to download and use the App on your personal device solely for personal, non-commercial purposes. All intellectual property rights in the App remain with Denys Mylymko.

You must not:

• Copy, modify, distribute, or create derivative works based on the App.
• Reverse engineer, decompile, or attempt to extract the source code of the App.
• Use the App for commercial purposes, resale, leasing, or sublicensing.
• Use automated tools, bots, or scripts to access, scrape, or interact with the App or its backend services.

Violation of these restrictions will result in immediate termination of your license.

2. Health and Fitness Disclaimer

Tonnage is a general fitness and workout-logging tool. It is not a medical device, and the training programs, weight suggestions, warm-up routines, calorie estimates, and AI coach responses it provides are for informational purposes only. They are not a substitute for professional medical advice, diagnosis, or treatment.

Important:

• Consult a qualified physician before beginning any exercise program, particularly if you have a medical condition, are pregnant, are recovering from an injury, or have not exercised recently.
• Strength training carries an inherent risk of injury. You are solely responsible for selecting safe loads, using correct technique, using appropriate safety equipment such as collars, safety bars, or a spotter, and stopping immediately if you feel pain, dizziness, or discomfort.
• Recommendations generated by the App are based only on the data you enter and on general training principles. They do not account for your medical history, injuries, fatigue, nutrition, or technique, and may be unsuitable for you.
• Calorie figures shown in the App are rough estimates derived from workout duration and training volume, not measurements.
• The App is not intended for use by individuals under the age of 16 without parental supervision.

3. Access and Subscription Terms

3.1 Access Options

The App is available in the following tiers:

• Free: unlimited logging of sets and workouts, the rest timer, a built-in training program and a warm-up program, your full workout history, basic personal records, cardio logging, the plate calculator, workout reminders, CSV export and import, and a limited number of custom routines, custom exercises, habits, measurement zones, and trial messages to the AI coach.
• Tonnage Pro (paid subscription): AI coach workout reviews and unlimited coach chat, all training programs and warm-up routines, full-history charts and advanced analytics, and unlimited custom routines, exercises, habits, and measurements, together with any other feature marked PRO in the App.

The exact set of free and paid features may change over time; the current split is always visible in the App.

3.2 Subscription Billing and Renewal

• Subscriptions are sold through the Apple App Store and are subject to Apple's payment terms. The available plans, their duration, and their price in your local currency are displayed in the App and by the App Store before you confirm any purchase.
• Payment is charged to your Apple ID account upon confirmation of purchase.
• Subscriptions renew automatically at the end of each billing period unless cancelled at least 24 hours before the renewal date. Your account is charged for renewal within 24 hours prior to the end of the current period.
• If a free trial is offered, its length and the price that applies afterwards are shown before purchase. Any unused portion of a free trial is forfeited when you purchase a subscription.
• You can manage or cancel your subscription at any time in your Apple ID account settings, under Subscriptions.
• Refunds for partially used subscription periods are not provided by us. Refund requests are handled by Apple; please contact Apple Support.

4. AI Coach Features

The App uses artificial intelligence to review your completed workouts, explain exercise technique, generate a daily coaching line, and answer your questions in the coach chat. By using these features, you acknowledge and agree that:

• AI responses are generated by a language model and may be inaccurate, incomplete, or unsuitable for your situation. They are not medical, physiotherapeutic, or nutritional advice.
• You are responsible for reviewing any suggestion — including suggested weights, repetitions, and progressions — before acting on it, and for adjusting it to your own condition and experience.
• The data sent to generate a response, and the data retained afterwards, are described in our Privacy Policy. Your full workout history is not uploaded to our servers.
• AI features depend on an internet connection and on a third-party provider, and may be temporarily unavailable, rate-limited, or discontinued.
• You must not use the coach chat to submit unlawful, abusive, or harmful content, or to attempt to extract the underlying prompts, models, or credentials.

5. Your Data and Backups

The App stores your training data on your device rather than in an account on our servers. This means:

• We cannot recover your data if you lose your device, reset it, or delete the App. We do not hold a copy.
• You are responsible for keeping your own backups. The App can export your complete history to a CSV file at any time, free of charge, and can import it back.
• Whether device backups (such as iCloud) include the App's data depends on your own device settings.

6. Privacy

Our Privacy Policy explains how we collect, use, and protect information, including health and fitness data you enter and the data processed by the AI coach. By using the App, you agree to the practices described in the Privacy Policy, which is available within the App and by contacting us at support.spotter@gmail.com.

7. Acceptable Use

You agree not to use the App in ways that:

• Violate any applicable laws or regulations.
• Infringe the rights of any third party, including intellectual property or privacy rights.
• Harm, disrupt, overload, or interfere with the App's servers or infrastructure, including circumventing usage limits on AI features.
• Attempt to gain unauthorized access to any part of the App or its backend systems, or to obtain paid features without payment.

We reserve the right to suspend or terminate your access immediately for any violation of these rules.

8. Disclaimer of Warranties

The App and all of its features are provided “AS IS” and “AS AVAILABLE,” without warranties of any kind, either express or implied. We do not guarantee:

• Uninterrupted or error-free operation of the App.
• The accuracy or completeness of training suggestions, calorie estimates, analytics, or AI-generated content.
• That the App will meet your specific fitness goals or health needs.

We disclaim all warranties of merchantability, fitness for a particular purpose, and non-infringement to the fullest extent permitted by applicable law.

9. Limitation of Liability

To the maximum extent permitted by law, Denys Mylymko is not liable for:

• Any injury, health outcome, or physical harm resulting from exercise performed while using the App or in reliance on its suggestions.
• Loss of data, including training history stored on your device, device malfunction, or App performance issues.
• Indirect, incidental, special, or punitive damages related to your use of, or inability to use, the App.

Liability Cap: our total liability under any circumstances is limited to the subscription fees you paid to us in the 12 months preceding the claim.

10. User Responsibility and Indemnification

By using the App, you agree to indemnify and hold harmless Denys Mylymko from any claims, damages, losses, or costs (including legal fees) arising from your misuse of the App, your violation of these Terms, or your infringement of any third-party rights.

11. Apple-Specific Terms

These Terms are concluded between you and the Developer only, and not with Apple Inc. (“Apple”). Accordingly:

• The Developer, not Apple, is solely responsible for the App and its content.
• Apple has no obligation to furnish any maintenance or support services for the App.
• In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price of the App to you. To the maximum extent permitted by applicable law, Apple has no other warranty obligation whatsoever with respect to the App.
• The Developer, not Apple, is responsible for addressing any claims relating to the App, including product liability claims, claims that the App fails to conform to legal or regulatory requirements, and claims arising under consumer protection or similar legislation.
• The Developer, not Apple, is responsible for the investigation, defense, settlement, and discharge of any third-party claim that the App infringes intellectual property rights.
• You represent that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
• Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, have the right to enforce these Terms against you.

12. Modifications to Terms

We reserve the right to update these Terms at any time. Material changes will be communicated through an in-app notice. Continued use of the App after the updated Terms take effect constitutes your acceptance of the changes.

13. Termination

These Terms remain in effect until terminated by you or by us. You may terminate them at any time by deleting the App. We may suspend or terminate your access to the App or to its server-based features without notice if you breach these Terms. Provisions relating to intellectual property, disclaimers, limitation of liability, and dispute resolution survive termination.

14. Dispute Resolution

In the event of a dispute arising out of or relating to these Terms or your use of the App, both parties agree to first attempt resolution through good-faith negotiation. Written claims must be responded to within 21 business days of receipt.

If the dispute cannot be resolved informally, it shall be subject to the laws of the jurisdiction in which Denys Mylymko is registered, and any unresolved dispute will be submitted to the competent courts of that jurisdiction. Nothing in these Terms deprives a consumer of the protection of mandatory provisions of the law of their country of residence.
