A note on what Lumiden is, and what it isn't

Lumiden is not a medical device

It doesn't diagnose, treat, cure, or prevent any condition, and it has not been cleared or approved by the FDA. It is not a substitute for a doctor, nurse, pharmacist, or any other licensed healthcare provider. Nothing Lumiden shows you, including checklists, notifications, AI chat replies, articles, and cost guides, is medical advice.

Your prescriber makes the medical decisions

Lumiden remembers what you tell it; your prescriber knows your full history. If anything in Lumiden disagrees with what your prescriber has told you, follow your prescriber. Never delay seeking medical care, or disregard something a clinician has told you, because of anything you read in Lumiden.

The AI chat is a general-knowledge companion, not a clinician

Talk it through is helpful for questions like "what does this feel like for other people," "is this a normal thing to expect," or "help me put words to what I'm noticing." It is not the right place for "should I take my dose tonight," "is this rash dangerous," or "what medication should I be on." For those, please reach your care team. AI responses are generated by a language model and can be wrong or incomplete, even when they sound confident.

Specific things Lumiden will not do

• Tell you how much medication to take
• Tell you to skip, delay, or change a dose
• Interpret a lab result, EKG, or scan
• Diagnose a symptom
• Recommend starting or stopping any medication
• Tell you a symptom is safe to ignore
• Answer drug-interaction questions (your pharmacist is the right call, and it's free)

If you notice any of these, contact your prescriber or seek urgent care. Don't ask Lumiden.

• Severe stomach pain that doesn't pass, especially pain that radiates to your back
• Vomiting that won't stop, or not keeping fluids down for more than a few hours
• Signs of a severe allergic reaction: swelling of the face, lips, or throat; trouble breathing; hives all over
• Severe headache, chest pain, fainting, sudden vision changes, or sudden weakness on one side
• Signs of low blood sugar (especially if you also take insulin or a sulfonylurea): shakiness, sweating, confusion, fast heartbeat
• Pain in the upper right abdomen, especially with yellowing of skin or eyes
• A possible pregnancy
• Any symptom that feels urgent or wrong

This list is not complete. It's a set of examples, not a screening tool. When in doubt, call your care team.

About crisis messages in chat

If a chat message looks like it describes an emergency, such as a possible overdose or thoughts of self-harm, Lumiden replies with a pre-written message pointing to emergency resources instead of an AI-generated one. This routing is a safety net, not monitoring; Lumiden does not watch over you and cannot summon help on your behalf.

About the data Lumiden collects

See our Privacy Policy for what we store, where, and for how long. The short version: your health information stays on your device. AI chat messages travel to Anthropic so a model can reply, and are not stored on Lumiden's servers.

About affiliate links

Some product or program links in Lumiden (especially in the Cost Guide) earn Lumiden a commission if you enroll. This costs you nothing extra and helps fund the app's development. We rank cards by what's likely most useful to you, never by what pays Lumiden the most. A partner link is never a medical recommendation. Full details are in our Affiliate Disclosure.
