Terms of Service
Last updated: November 4, 2026
Please read these Terms of Service ("Terms") before using the Shoulder Rehab mobile application (the "App") operated by Twin Tip Solutions ("we", "our", or "us").
1. Acceptance of Terms
By downloading, installing, or using the App, you agree to these Terms. If you do not agree, do not use the App.
2. Not Medical Advice
The App is a personal tracking tool for shoulder rehabilitation. It is not a medical device and does not provide medical advice, diagnosis, or treatment.
- Angle measurements are estimates and should not be relied on for clinical decisions.
- The App does not replace evaluation or guidance from your surgeon, physical therapist, or other healthcare provider.
- Only move your arm within the range your care team allows. Stop if you feel pain and contact your healthcare provider.
3. Use of the App
You agree to use the App only for personal rehabilitation tracking, and not to use it unlawfully, reverse engineer it, interfere with its services, or use it to collect data about other people without their consent.
4. Your Data
You are responsible for the data you enter, including measurements and photos. Data is handled as described in our Privacy Policy.
5. AI-Assisted Measurements
The App locates joints in your photos automatically and can use an AI model to check those photos. You acknowledge that these measurements are estimates, that accuracy depends on factors such as camera position, lighting, clothing, and posture, and that they are not a substitute for clinical tools such as a goniometer. We make no guarantee of their accuracy.
6. Intellectual Property
The App and its contents are owned by Twin Tip Solutions and protected by copyright, trademark, and other laws.
7. Disclaimer of Warranties
The App is provided "as is" and "as available" without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, uninterrupted or error-free operation, or the accuracy of measurements.
8. Limitation of Liability
To the maximum extent permitted by law, Twin Tip Solutions is not liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, use, or goodwill, arising from your use of the App. Our total liability for all claims relating to the App will not exceed the amount you paid for the App, if any.
9. Changes
We may modify, suspend, or discontinue the App, and update these Terms. Continued use after changes means you accept the revised Terms.
10. Termination
We may suspend or end your access to the App's online features if you breach these Terms.
11. Governing Law
These Terms are governed by the laws of the United States, without regard to conflict-of-law provisions.
