PLEASE READ THIS SECTION CAREFULLY

2.1 Not Medical Advice

Mallet is a wellness and lifestyle application. It is NOT a medical device, does NOT provide medical advice, and is NOT intended to diagnose, treat, cure, or prevent any disease or health condition.

The information, recommendations, and insights provided by Mallet, including those generated by our AI assistant, are for general informational and educational purposes only. They are not a substitute for professional medical advice, diagnosis, or treatment.

2.2 Consult Healthcare Professionals

Always seek the advice of your physician, registered dietitian, or other qualified health provider with any questions about medical conditions, new diet or exercise programs, supplement regimens, interpreting bloodwork, medication interactions, or any health-related decisions.

Never disregard professional medical advice or delay seeking it because of something from this app.

2.3 AI Limitations

Our AI features, including the Noot assistant, provide suggestions based on information you provide and general wellness principles. The AI cannot examine you physically, does not have your complete medical history, may make errors, and is not a replacement for qualified healthcare professionals.

2.4 Emergency Situations

If you think you may have a medical emergency, call your doctor, go to the nearest emergency room, or call 911 immediately. Mallet is not designed for emergencies.

2.5 Bloodwork, Supplements, and Medications

Our analysis of bloodwork is not diagnostic and should be discussed with your healthcare provider. Before starting, stopping, or changing any supplement or medication, consult a qualified healthcare professional.

2.6 Assumption of Risk

By using Mallet, you acknowledge that physical exercise, dietary changes, and supplements carry inherent risks. You assume full responsibility for any risks, injuries, or damages resulting from your use of the Service or reliance on information provided.

If you are a California resident, you expressly waive California Civil Code Section 1542, which provides: "A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release."

2.7 Glucose Monitoring

Glucose data, trends, and metabolic scores displayed in the Service are for informational and general wellness purposes only. They should not be used to make insulin dosing, medication, or other clinical decisions. If you use a continuous glucose monitor, always follow your healthcare provider's guidance for interpreting glucose data.

2.8 Peptides and Injections

The Service provides tracking tools for peptide administration, including reconstitution calculations and injection site rotation. These tools are for personal record-keeping only. Reconstitution calculations are estimates and should be verified independently. Always consult a qualified healthcare professional before starting, changing, or stopping any peptide or injectable protocol.
