5. Health & Fitness Disclaimer

• Lightweight is a tracking tool, not a medical device or training service. We are not certified trainers, physiotherapists, or medical professionals.

6. AI Insights Disclaimer

• AI output is informational only. It is not training advice, medical advice, or coaching guidance, and it should not be treated as such.
• AI output may be inaccurate, generic, contradict accepted training principles, or miss context about your individual circumstances. We do not review or validate AI output before showing it to you.
• Do not rely on AI insights as authoritative. Apply your own judgment and consult qualified professionals for training and health decisions.

9. Disclaimer of Warranties & Liability

• The app is provided as-is and as-available, without warranty of any kind, express or implied.
• We do not warrant that the app will be error-free, uninterrupted, or that data sync will always succeed.
