Terms of Service

1. Acceptance of Terms

By downloading, installing, or using Teo ("the App"), you agree to be bound by these Terms of Service. If you do not agree, do not use the App.

2. Description of Service

Teo is a free, open-source fitness application for Apple Watch and iPhone that provides training readiness scoring, workout tracking, heart rate zone analysis, guided workouts, and related fitness metrics. The App reads data from Apple HealthKit and processes it entirely on your device.

3. Not Medical Advice

Teo is a fitness and training tool, not a medical device. The readiness scores, heart rate zone data, cardiac load calculations, and all other metrics provided by Teo are for informational and training purposes only. They are not intended to diagnose, treat, cure, or prevent any disease or medical condition.

Always consult a qualified healthcare provider before starting any exercise program or making decisions based on health data. If you experience chest pain, dizziness, or other symptoms during exercise, stop immediately and seek medical attention.

4. Accuracy Disclaimer

Teo's readiness scores, fitness metrics, cardiac load calculations, and workout suggestions are based on published sports-science models and the sensor data provided by your Apple Watch. While we strive for accuracy, these calculations depend on the quality of sensor data and the applicability of general models to your individual physiology. Results may vary and should not be relied upon as precise measurements.

5. Open Source

Teo's source code is available under the MIT License at github.com/santekotturi/teo. You are free to use, modify, and distribute the code in accordance with the MIT License. The MIT License applies to the source code only and does not grant rights to the Teo name, logo, or trademarks.

6. User Responsibilities

You agree to:

• Use the App in compliance with all applicable laws
• Not use the App as a substitute for professional medical advice
• Ensure your Apple Watch sensors are functioning properly for accurate readings
• Take responsibility for your own health and safety during exercise

7. Privacy

Your use of Teo is also governed by our Privacy Policy, which describes how we handle (or rather, don't handle) your data. In short: all data stays on your device.

8. Teo+ (Future Paid Service)

Teo+ is a planned subscription service that will provide AI-powered coaching features requiring server-side processing. When Teo+ launches, it will be governed by additional terms specific to that service. The free version of Teo will remain free and fully functional without Teo+.

9. Donations

Teo may offer optional donations via GitHub Sponsors or in-app purchases. Donations are voluntary, non-refundable, and do not entitle donors to additional features, priority support, or any other consideration beyond supporting the project.

10. Intellectual Property

The Teo name, logo, and branding are the property of Sante Kotturi. The source code is licensed under MIT. Third-party trademarks (Apple, Apple Watch, HealthKit, Garmin, WHOOP) belong to their respective owners and are used for descriptive purposes only.

11. Disclaimer of Warranties

The App is provided "as is" and "as available" without warranties of any kind, either express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the App will be uninterrupted, error-free, or free of harmful components.

12. Limitation of Liability

To the maximum extent permitted by applicable law, Sante Kotturi and any contributors to the Teo project shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or revenues, whether incurred directly or indirectly, or any loss of data, use, goodwill, or other intangible losses resulting from your use of the App.

13. Changes to Terms

We may update these terms from time to time. The updated version will be posted here with a new date. Continued use of the App after changes constitutes acceptance of the revised terms.

14. Governing Law

These terms are governed by the laws of the State of California, United States, without regard to conflict of law principles.
