1. Acceptance of Terms

By downloading, installing, or using the TENACE mobile application (“Tenace Training”, hereinafter the “App”) or visiting https://tenace.fit (the “Website”), you agree to be bound by these Terms of Service (“Terms”). If you do not agree with any part of these Terms, you must not use the App or the Website.

These Terms constitute a legally binding agreement between you (“User”) and Gustavo Medeiros Souza (“Developer”, “we”, “us”, or “our”), an individual developer based in Brazil.

2. Description of Service

TENACE (published on the Apple App Store and Google Play under the name “Tenace Training”) is a personal fitness logging application that allows users to:

The App operates on a freemium model: a meaningful set of core features is available at no cost. Certain advanced features may require a paid subscription or one-time in-app purchase (“Premium”). The specific features available under each tier are displayed within the App and are subject to change with prior notice.

All workout and body data is stored locally on your device. The App does not transmit personal fitness data to external servers.

3. Eligibility

You must be at least 13 years of age to use the App. By using the App, you represent and warrant that you meet this age requirement. If you are under 18 years of age, you represent that you have obtained parental or legal guardian consent to use the App and to agree to these Terms.

The App is not directed at children under the age of 13, and we do not knowingly collect information from children under 13. If we become aware that a child under 13 has provided personal information, we will take reasonable steps to delete it.

4. Health & Medical Disclaimer

THE APP IS NOT A MEDICAL PRODUCT AND IS NOT INTENDED TO PROVIDE MEDICAL ADVICE. The information, features, and content available through the App — including but not limited to workout suggestions, progressive overload hints, body composition logging, and achievement metrics — are provided for general informational and motivational purposes only. They do not constitute medical advice, diagnosis, or treatment.

You should consult a qualified physician, sports medicine doctor, or other licensed healthcare professional before beginning any new exercise program, especially if you have any pre-existing medical condition, injury, cardiovascular risk factors, or other health concerns.

By using the App, you acknowledge and agree that:

If you experience pain, dizziness, shortness of breath, chest pain, or any other concerning symptoms during exercise, stop immediately and seek medical attention.

5. User Responsibilities

You agree to use the App solely for lawful, personal, non-commercial purposes and in accordance with these Terms. You agree that you will not:

You are solely responsible for maintaining the security of your device and for all activity that occurs on the App via your device.

6. Intellectual Property

The App, including its design, source code, graphics, text, icons, logos, the TENACE name and brand identity, and all other content and materials (collectively, the “Content”), are the exclusive property of Gustavo Medeiros Souza and are protected by applicable intellectual property laws, including copyright and trademark law.

Subject to your compliance with these Terms, the Developer grants you a limited, non-exclusive, non-transferable, revocable licence to download and use the App on your personal device solely for your personal, non-commercial use.

This licence does not include any right to: sublicense, sell, resell, transfer, assign, or commercially exploit the App; modify or make derivative works of the App; or use the App's Content for any commercial purpose or for any public display. Any rights not expressly granted herein are reserved by the Developer.

Any feedback, suggestions, or ideas you voluntarily provide regarding the App may be used by the Developer without obligation or compensation to you.

7. Freemium & Subscriptions

The App offers a free tier that provides access to core workout logging and tracking features at no charge. Certain premium features may be unlocked through in-app purchases, including auto-renewing subscriptions or one-time purchases (“Premium Access”).

All billing for in-app purchases on iOS devices is handled by Apple Inc. through the App Store. All billing for in-app purchases on Android devices is handled by Google LLC through Google Play. The Developer does not directly process payment information.

By initiating an in-app purchase, you agree to the payment terms of the applicable platform (Apple App Store or Google Play). Subscription renewals, cancellations, and refund requests are governed by the respective platform's policies. To cancel a subscription or request a refund, you must do so through your App Store or Google Play account settings.

The Developer reserves the right to modify feature availability between the free and premium tiers, or to change subscription pricing, at any time. Any such changes will be communicated to existing subscribers with reasonable notice and will not affect your current subscription period.

8. Disclaimers & Limitation of Liability

THE APP IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED. To the fullest extent permitted by applicable law, the Developer disclaims all warranties, express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, non-infringement, and any warranty that the App will be uninterrupted, error-free, or free of viruses or other harmful components.

The Developer does not warrant that: (a) the App will meet your specific requirements; (b) the App will be available at any particular time or location; (c) any errors or defects will be corrected; or (d) the results of using the App will be accurate, complete, or reliable.

To the fullest extent permitted by applicable law, in no event shall the Developer be liable for any indirect, incidental, special, consequential, or punitive damages — including but not limited to loss of profits, data, use, goodwill, or other intangible losses — arising out of or relating to your use of the App, even if the Developer has been advised of the possibility of such damages.

In any event, the Developer's total cumulative liability to you for all claims arising out of or relating to these Terms or the App shall not exceed the greater of: (a) the amount you paid to the Developer for the App or any in-app purchase in the twelve months preceding the claim, or (b) US$10.

Some jurisdictions do not allow the exclusion of certain warranties or the limitation of liability for certain types of damages, so some of the above limitations may not apply to you.

9. Indemnification

You agree to defend, indemnify, and hold harmless Gustavo Medeiros Souza from and against any and all claims, damages, losses, liabilities, costs, and expenses (including reasonable legal fees) arising out of or relating to: (a) your use of the App or the Website; (b) your violation of these Terms; (c) your violation of any third-party right, including any intellectual property right or privacy right; or (d) any injury or damage you cause to yourself or others through or in connection with physical exercise undertaken in reliance on information from the App.

10. Changes to Terms

The Developer reserves the right to modify these Terms at any time. When changes are made, the “Last updated” date at the top of this page will be revised. For material changes, we will make reasonable efforts to notify users — for example, via a notice within the App or on the Website.

Your continued use of the App after the effective date of revised Terms constitutes your acceptance of those Terms. If you do not agree to the updated Terms, you should stop using the App.

11. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the Federative Republic of Brazil, without regard to its conflict of law principles. Any dispute arising out of or relating to these Terms or the App that cannot be resolved informally shall be submitted to the exclusive jurisdiction of the courts located in Brazil.

If you are a consumer resident in a jurisdiction with mandatory consumer protection laws that provide you with greater rights, those laws will apply to the extent they conflict with Brazilian law.
