Terms & Conditions
Effective date: March 4, 2026
These terms govern your use of the Duro mobile application ("the App") operated by EP Studios ("we", "us", "our"). By using Duro, you agree to these terms.
1. The service
Duro is a workout tracking app for iOS and Apple Watch. It helps you log exercises, track training volume, monitor recovery, and view strength trends. Some features use AI-generated content to provide coaching insights.
2. Not medical advice
Duro is a fitness tracking tool, not a medical device. Nothing in the app constitutes medical advice, diagnosis, or treatment. Training recommendations, recovery estimates, hypertrophy scores, and AI-generated coaching messages are informational only. Consult a qualified healthcare professional before starting or modifying any exercise program. Use the app at your own risk.
3. Your data
You retain ownership of all workout data you create in Duro. By using the App, you grant us a limited license to process your workout data as described in our Privacy Policy — including transmitting it to our servers and third-party AI providers to deliver app features.
4. Acceptable use
You agree not to:
- Reverse engineer, decompile, or disassemble the App
- Attempt to access our servers or APIs outside of normal app usage
- Use the App for any unlawful purpose
5. AI-generated content
Duro uses AI models to generate coaching messages and training insights. AI-generated content may be inaccurate, incomplete, or inappropriate. We do not guarantee the accuracy of any AI output. You should not rely on AI-generated content as a substitute for professional advice.
6. Apple HealthKit
Duro integrates with Apple HealthKit to read heart rate data and write workout sessions. HealthKit access requires your explicit permission and can be revoked at any time in iOS Settings. We handle HealthKit data in accordance with Apple's guidelines and our Privacy Policy.
7. Availability
We aim to keep Duro available and functional but do not guarantee uninterrupted access. We may update, modify, or discontinue features at any time. Server-dependent features (such as AI coaching) require an internet connection and may be unavailable during outages.
8. Limitation of liability
To the maximum extent permitted by law, EP Studios is not liable for any indirect, incidental, or consequential damages arising from your use of the App. This includes but is not limited to data loss, injury during exercise, or reliance on AI-generated content. Our total liability is limited to the amount you paid for the App.
9. Termination
You may stop using Duro at any time by deleting the App. We may suspend or terminate access to server-dependent features if these terms are violated.
10. Changes
We may update these terms. The effective date at the top will reflect the latest revision. Continued use of Duro after changes constitutes acceptance.
11. Governing law
These terms are governed by the laws of the jurisdiction in which EP Studios is established.
