Health & Medical Disclaimer

Performance does not diagnose, treat, cure, or prevent disease and does not provide medical, psychiatric, emergency, or telemedicine services. Information in the app is intended to support fitness and wellness decisions, not clinical decisions.

If you need medical advice, diagnosis, treatment, medication guidance, or interpretation of a concerning symptom or laboratory result, consult a qualified healthcare professional.

Exercise can involve risks including fatigue, falls, musculoskeletal injury, cardiovascular events, heat illness, dehydration, and other serious harm. Your appropriate training level depends on factors Performance cannot fully know.

• Stop or reduce exercise if you experience concerning pain, chest pain, fainting, severe shortness of breath, neurological symptoms, or another warning sign.
• Seek professional guidance before beginning or materially changing training when you have a medical condition, are pregnant, are recovering from injury or illness, or have been advised to restrict exercise.
• For a medical emergency, call 911 or your local emergency service. Do not use Performance as an emergency service.

Recovery, sleep, heart-rate, HRV, strain, energy, pace, and similar metrics can be affected by device accuracy, sensor placement, missing data, permissions, algorithms, and normal biological variation. They may be delayed, incomplete, or wrong.

Do not use a Performance score or wearable metric as a diagnosis or as the sole basis for a medical decision.

Performance may let you record laboratory values or attach a PDF lab report and may display ranges, changes, or sourced educational context. Those features do not create a diagnosis, determine whether a result is clinically normal for you, or replace review by a licensed clinician.

Reference ranges vary by laboratory, method, medical history, medications, age, sex, and clinical context. Discuss abnormal, unexpected, or concerning results with an appropriate healthcare professional.

Performance may record items you choose to enter and may present factual safety or regulatory warnings. It does not prescribe these items or recommend starting, stopping, dosing, increasing, stacking, cycling, or combining them.

Recording an item does not mean it is safe, legal, appropriate, pure, effective, or endorsed by Performance. Interactions, contraindications, contamination, dosing risk, and individual medical factors require professional assessment.

Nutrition targets and meal information are fitness-oriented estimates. They can be inappropriate for people with allergies, eating disorders, metabolic disease, kidney disease, pregnancy, medication-related restrictions, or other clinical needs. Seek qualified care when nutrition requires medical management.

New third-party-AI weekly meal-plan generation is disabled in the current iOS release.

When you explicitly enable model-routed Polaris processing, an AI provider may generate a response from the bounded Performance context sent for your question. AI-generated content may be inaccurate or omit important context and is labeled accordingly in the app.

Do not treat an AI-generated response as medical advice, a prescription, an emergency assessment, or a substitute for a qualified professional.

You are responsible for deciding whether to use a fitness or wellness feature and for obtaining appropriate professional care. Performance cannot observe your complete medical history, current symptoms, environment, technique, or all substances and treatments that may affect you.

If a clinician has given you restrictions or instructions that conflict with Performance, follow the clinician's instructions.
