You choose exactly what they see, never your journal, readings or notes, and you can remove them any time. There are lessons made for them too, including Partner Support in the third trimester and Partner Experience in Postpartum.

Questions
Before you join.
Honest answers, in plain language.
Is this medical advice?
No. Haja Health, including Empowering Pregnancy, is education. It doesn’t replace your own care team, the people who actually know your situation. Answers in Office Hours and Ask Haja are general education, not advice about your personal care. Always bring your specific questions to your care team.
Do I need to download an app?
No. Haja Health works in your web browser, so there's no app store needed. If you'd like, you can add it to your phone's home screen so it opens like an app. See the simple steps for iPhone and Android.
What is Ask Haja, exactly?
Ask Haja is where Office Hours members send their questions to Dr. Chun. It is part of Office Hours ($27/month), not the free plan. He answers questions at Office Hours, first come, first served, and his written answers show up in your app. It isn’t an AI chatbot: your question goes to him.
Can I cancel anytime?
Yes. Office Hours is a monthly membership, not a contract. Cancel any time from your account and you won't be billed again. If it isn't right for you, ask within 7 days of your first payment and we'll refund it in full. See our Refund Policy. Everything else in the app stays free.
Is this covered by insurance?
No — this is a separate membership from your medical care and isn't billed through insurance.
Do I need to already be a patient of Dr. Chun's?
No. Haja Health is open to everyone, wherever you live. Joining doesn’t make you Dr. Chun’s patient, and it doesn’t replace your own care team.
What happens after I have my baby?
Your membership keeps going — the Fourth Trimester lessons and tools (free), and Office Hours if you join, cover postpartum recovery, feeding, mental health, and the rest of the fourth trimester too.
Is my information private?
We take your privacy seriously. You can try a free lesson and the quiet minute without an account or payment details, and our Privacy Policy explains what we collect and how it's used.
Know what to expect. Know what to ask.
Understand your options, prepare for birth, and live for today. Join free, open a lesson, and see how it feels.
