By downloading, installing, or using STRN ("the App"), you agree to these Terms of Use. If you do not agree, do not use the App.
STRN is a free, offline-first strength training tracker. It allows you to log workouts, track body measurements, create training programs, and view your progress. All data is stored locally on your device.
The App does not require registration or an account. There are no subscriptions or in-app purchases.
All workout data, body metrics, and preferences are stored on your device. You are solely responsible for backing up your data using the built-in export feature. The developer is not responsible for data loss due to device failure, app uninstallation, or any other cause.
The App is a fitness tracking tool, not a medical device. It does not provide medical, health, or fitness advice. Information displayed (e.g. estimated 1RM, personal records) is for informational purposes only. Always consult a qualified professional before starting or modifying an exercise program.
Physical exercise carries inherent risks, including risk of injury. By using the App to plan or track workouts, you acknowledge that you participate in exercise at your own risk. The developer is not liable for any injuries or damages resulting from workouts performed while using the App.
The App's name, logo, design, and source code are the property of the developer. You may not copy, modify, distribute, or reverse-engineer the App except as permitted by applicable law.
The App is provided "as is" without warranties of any kind, either express or implied. The developer does not warrant that the App will be error-free, uninterrupted, or free of harmful components.
To the maximum extent permitted by applicable law, the developer shall not be liable for any indirect, incidental, special, or consequential damages arising from the use or inability to use the App, including but not limited to data loss, device damage, or personal injury.
These Terms may be updated from time to time. Continued use of the App after changes constitutes acceptance of the revised Terms.
