8. Health Information and GLP-1 Tracking Disclaimer

Not a medical service. CalZen is a personal tracking, calculation, and informational application. It is not a medical service and is not intended to function as a medical device. CalZen does not provide medical advice, diagnosis, prescriptions, or treatment, and does not replace a qualified healthcare professional. Its calorie tracking, meal analysis, nutrition goals, weight tracking, GLP-1 medication logs, reminders, charts, and other tracking features are provided for convenience and informational purposes only.

Consult your healthcare professional. Consult your physician or another qualified healthcare professional before starting a diet, fitness program, or weight loss plan. Nutrition estimates and goals based on your entries do not constitute a medical assessment and may not account for your medical conditions, health history, or individual nutritional needs.

Medication and dosing decisions. Use the GLP-1 tracker only to record a treatment plan prescribed to you by a qualified healthcare professional. Decisions about whether a medication is suitable for you, which medication to use, the dose, administration method, dosing interval, and any treatment changes must be made with your prescribing healthcare professional. Consult that professional before starting or changing treatment. Do not start, stop, switch, increase, decrease, skip, repeat, or reschedule a dose based on CalZen's calculations, charts, notifications, or other content. If you are unsure about a dose or a missed dose, contact your prescriber or pharmacist.

Your responsibilities and risks. You are responsible for entering and checking accurate information, recording your prescribed regimen correctly, following your clinician's instructions and the medication's official instructions, and seeking medical advice when needed. You remain responsible for your own decisions and actions concerning medication use and assume the risks associated with decisions you make independently of professional medical guidance. Listing a medication or allowing you to record a dose does not mean that CalZen recommends or confirms its suitability or safety for you.

Calculations and results. Medication-level charts, timing estimates, supply projections, and other calculated results are approximations based on your entries and the assumptions used by the App. They do not measure the actual concentration of medication in your body, determine a safe or effective dose, establish whether a medication is working, or confirm that a product is safe to use. Individual circumstances and inaccurate or incomplete records can affect the results. CalZen does not guarantee weight loss, medication effectiveness, freedom from side effects, or any other health outcome.

Reminders, symptoms, and emergencies. Reminders and notifications may be delayed or fail to arrive; they do not verify that a dose is due or safe to take. Symptom entries and safety messages are not a diagnosis, medical monitoring, or a complete assessment of risk. The absence of a warning does not mean that your symptoms or treatment are safe. Your entries are not monitored by a healthcare professional through CalZen. For a medical emergency, contact your local emergency services immediately.

Limitation of liability. To the extent permitted by applicable law, 42apps LLC is not liable for harm resulting from inaccurate user entries, failure to follow professional medical advice, or dietary or treatment decisions made in reliance on the App instead of professional medical guidance. Nothing in these Terms excludes or limits liability that cannot lawfully be excluded or limited, or affects your mandatory consumer rights.
