Your health data is not our product.
Your health questions are personal. Leo is built to protect your information, explain things clearly, and help you feel more prepared for care.
No data selling. No hidden agenda. No diagnosis claims.
Your privacy comes first
You should not have to trade privacy for health support.
Leo gives you a private place to ask health questions, understand your care, and prepare for what comes next. What you share with Leo stays focused on helping you.
We do not sell your data. We do not build ProjectLeo around advertising. We do not share your health information with hospitals, insurers, or drug companies for their benefit.
Leo works for you.
Your data has a job
Leo uses the information you choose to share to help you understand your health questions.
That may include explaining medical terms, helping you prepare questions for a doctor, summarizing information you provide, or helping you organize appointments, medicine, records, and next steps.
If information does not help Leo support you, we should not ask for it.
What we do not do
We do not sell your personal health information.
We do not use your private health conversations for advertising.
We do not claim Leo can diagnose you.
We do not claim Leo can prescribe treatment.
We do not replace your doctor or care team.

How Leo uses AI safely
When Leo is unsure, it should say so. When a question needs medical care, Leo should tell you to contact a qualified healthcare provider.
In an emergency, call 911.
Leo can help you:
Put health information into plain English
Prepare questions for a doctor
Organize what to say at an appointment
Understand information you choose to share
Think through what to ask next
Leo does not:
Diagnose conditions
Prescribe medicine
Replace a doctor
Make emergency decisions
Promise a health outcome
How we work to reduce bias
Health support should work for more people.
AI can repeat unfair patterns from healthcare. We test Leo to reduce bias, improve safety, and make support more useful across different backgrounds, bodies, languages, and care experiences.
When we find a problem, we work to fix it.
This work is never finished.
Your health information belongs to you.
You choose what to share with Leo. You can see the information connected to your account. You can delete information you no longer want Leo to keep. You decide if and when to share information with a doctor, caregiver, or anyone else.
Nothing should happen with your health information in secret.
