Mobile Application Terms: These terms govern your use of the CutEngine and CardioEngine mobile applications (collectively, our “Apps”).

General Terms

By downloading, installing, and using CutEngine or CardioEngine, you confirm that you are in agreement with and bound by the terms of service contained in the Terms & Conditions outlined below. These terms apply to both applications and any communications between you and Feeling Mindful Labs LLC.

Under no circumstances shall the Feeling Mindful Labs team be liable for any direct, indirect, special, incidental or consequential damages, including, but not limited to, loss of data or profit, arising out of the use, or the inability to use, the applications, even if an authorized representative has been advised of the possibility of such damages.

License

Feeling Mindful Labs LLC grants you a revocable, non-exclusive, non-transferable, limited license to download, install and use the applications strictly in accordance with the terms of this Agreement.

These Terms & Conditions are a contract between you and Feeling Mindful Labs LLC (referred to as “we”, “us” or “our”), the provider of CutEngine, CardioEngine, and associated services.

Definitions

• Company: when this policy mentions “Company,” “we,” “us,” or “our,” it refers to Feeling Mindful Labs LLC, (610 Terrell Hill Dr, Austin, TX 78704).
• Apps: CutEngine (body composition and nutrition tracking) and CardioEngine (heart rate zone coaching), both published by Feeling Mindful Labs LLC.
• Country: the United States.
• Device: any internet connected device such as a phone or tablet that can be used to use our Apps.
• Service: refers to the services provided by our Apps as described in these terms.
• You: a person or entity that has downloaded and uses one or more of our Apps.

Health & Fitness Disclaimer

Our Apps provide fitness tracking, nutrition planning, and heart rate zone coaching for informational purposes only. Neither CutEngine nor CardioEngine is a medical device, and neither provides medical advice.

• Consult a physician before starting any diet or exercise program.
• Calorie and macro targets (CutEngine) are estimates based on formulas and your data. Individual results may vary.
• Body fat estimates from tape measurements and calipers have inherent margins of error.
• Heart rate zone thresholds (CardioEngine) are calculated from general models and may not reflect your true physiological zones. A lab-based lactate threshold test provides the most accurate zones.
• Real-time heart rate readings depend on BLE device accuracy and sensor placement. CardioEngine is not responsible for inaccurate readings from third-party heart rate monitors.
• Recovery scores based on sleep and HRV data are general indicators, not clinical assessments.
• Enhancement tier recommendations (CutEngine) are based on general guidelines and should not replace professional medical advice regarding pharmaceuticals.
• Do not rely on our Apps to make medical decisions or diagnose health conditions.

By using our Apps, you acknowledge that all dietary, fitness, and heart rate zone recommendations are general in nature and you assume full responsibility for your health decisions.
