IMPORTANT: BioTrack is a tracking and general wellness tool. It is NOT a medical device, it does not diagnose and it does not replace professional medical advice.

5.2 Limitations

  • The health data shown (heart rate, HRV, SpO2, blood pressure, sleep) is informational and may not be accurate.
  • The AI may extract data or generate replies that are incorrect, and it does not issue medical prescriptions.
  • The Coach's exercise, nutrition or recovery recommendations are guidance only and do not take specific medical conditions into account.
  • Recovery metrics are estimates based on algorithms, not clinical assessments.

5.3 User Responsibility

  • Consult a healthcare professional before starting any exercise or diet program.
  • Do not ignore professional medical advice because of information in BioTrack.
  • Stop immediately if you feel pain, dizziness or discomfort during exercise.
  • If you have any medical condition (heart disease, diabetes, hypertension, injuries, pregnancy, etc.), consult your doctor before following BioTrack's recommendations.
  • HealthKit and Health Connect data depends on the accuracy of your devices and may contain errors.

5.4 Disclaimer of Liability for Injuries

BioTrack is not responsible for:

  • Injuries resulting from following routines or recommendations without checking them
  • Health problems resulting from nutrition plans or calorie restrictions
  • Medical decisions made on the basis of data shown in the App
  • Errors in data coming from Apple HealthKit, Health Connect or other sensors

6. AI Features: Specific Terms

6.1 Nature of the Service

BioTrack uses OpenRouter as its single gateway to analyze nutrition labels and provide the Coach. It is important that you understand that:

  • You should check the values before saving foods
  • Coach replies may use your BioTrack profile and your workout, nutrition and recovery context
  • The AI features do not provide diagnosis, treatment or professional medical advice
  • The Coach can log and change your data. Depending on the mode you choose in Coach → Options → Coach changes, each change waits for your confirmation or applies directly; either way it appears in the chat as a card. The Coach memory updates automatically and you can review and forget it in Coach → Memory

  • We are not responsible for decisions made on the basis of data you have not reviewed.
  • We recommend checking important information against the original label or with a qualified professional, as appropriate.
