By accessing or using the Service, you agree to be bound by these Terms of Use ("Terms"). If you do not agree to these Terms, you may not access or use the Service. Your continued use of the Service constitutes your acceptance of any updates or modifications to these Terms.

2. Description of Service

SinewFit is a web-based fitness application that provides AI-generated workout plans, exercise recommendations, and workout logging tools. The Service uses artificial intelligence to create personalized fitness programs based on user-provided information such as fitness goals, experience level, available equipment, and physical metrics.

The Service is intended for informational and educational purposes only. SinewFit does not provide medical advice, diagnosis, or treatment of any kind.

3. Medical Disclaimer

The fitness information provided by SinewFit is for educational and informational purposes only and is not intended as a substitute for professional medical advice, diagnosis, or treatment. Always seek the advice of your physician or other qualified health care provider with any questions you may have regarding a medical condition or before starting any exercise program.

SinewFit does not provide medical advice. The AI-generated workout plans and exercise recommendations are created algorithmically and have not been reviewed or approved by a medical professional. You should consult a physician before beginning any exercise program, particularly if you have any pre-existing health conditions, injuries, or concerns.

You acknowledge and agree that you assume all risk of injury, disability, or death that may result from following any workout plans, exercise recommendations, or other content provided by the Service. SinewFit and its creators, operators, and affiliates shall not be held liable for any injuries, health complications, or damages sustained while following AI-generated workout plans or exercise recommendations.

If you experience any pain, discomfort, or adverse physical symptoms during exercise, you should immediately stop and seek medical attention.

4. Assumption of Risk

You acknowledge that physical exercise and fitness activities involve inherent risks, including but not limited to: physical injury, muscle strains, sprains, fractures, joint damage, cardiovascular events, disability, and in extreme cases, death. These risks may result from your own actions, the actions of others, equipment malfunction, or the conditions of the exercise environment.

By using the Service, you voluntarily assume all such risks, whether known or unknown, even if arising from the negligence of SinewFit or its creators, and you agree to accept full responsibility for any injury, illness, damage, loss, or cost resulting from your participation in any exercise or fitness program recommended by the Service.

5. Limitation of Liability

To the maximum extent permitted by applicable law, SinewFit, its creators, operators, affiliates, officers, directors, employees, agents, and licensors shall not be liable for any direct, indirect, incidental, consequential, special, exemplary, or punitive damages arising out of or in connection with your use of, or inability to use, the Service.

This limitation applies to all claims, whether based on warranty, contract, tort (including negligence), strict liability, or any other legal theory, and whether or not SinewFit has been advised of the possibility of such damages. This includes, without limitation, damages for personal injury, pain and suffering, emotional distress, loss of revenue or profits, loss of data, or any other damages.

In no event shall the total aggregate liability of SinewFit exceed the amounts paid by you, if any, for accessing the Service during the twelve (12) months preceding the claim.

6. Indemnification

You agree to indemnify, defend, and hold harmless SinewFit and its creators, operators, affiliates, officers, directors, employees, and agents from and against any and all claims, damages, obligations, losses, liabilities, costs, or expenses (including but not limited to attorney's fees) arising from: (a) your use of the Service; (b) your violation of these Terms; (c) your violation of any rights of a third party; or (d) any injury or harm you sustain as a result of following workout plans, exercise recommendations, or other content provided by the Service.

9. AI-Generated Content

The workout plans, exercise recommendations, and other fitness content provided by the Service are generated algorithmically using artificial intelligence. While we strive for accuracy and safety, AI-generated content may contain errors, inaccuracies, or recommendations that may not be appropriate for your specific circumstances.

You should always use your own judgment when following AI-generated workout plans. If an exercise feels unsafe, causes pain, or seems inappropriate for your fitness level, you should skip it or substitute an alternative. The Service is a tool to assist your fitness journey, not a replacement for professional guidance from certified personal trainers or medical professionals.
