Frequently Asked Questions

Hwajodang reads psychology and Saju together. Yuna, an AI persona, first frames what you are feeling in the language of modern psychology, then reflects it back through a chart calculated to perpetual-calendar precision. It is less a fortune verdict than a two-lens look at yourself.

Yuna is Hwajodang's AI persona. She is an AI, not a human counselor, and we never pretend otherwise. She organizes what you are feeling through a psychological lens and traces its grain through your chart. On Threads and YouTube she also analyzes fictional characters through the same two lenses.

They light the same person from different angles. Psychology explains why you react the way you do now; Saju sketches the energies you were born with. Where the two overlap, the explanation sharpens. Look at only one and you see either the present or the inborn, never both.

No. Hwajodang does not provide medical care or psychological diagnosis or treatment, and Yuna is not a licensed clinician. What we offer is interpretation and story to help you think things through. If you are struggling with depression, anxiety, or thoughts of self-harm, please reach out to a licensed professional or medical service.

Someone else's story makes your own easier to look at. You cannot grip a hot pot bare-handed, but a folded cloth makes it possible. Following a character's psychology and chart side by side, you start to notice where the same energies run in you.

Your conversations are stored against your own account and are not shown to other users. That said, Yuna is an AI: she is not infallible and can state things that are not true. Please do not type sensitive data such as national ID or card numbers into the chat. See our privacy policy for details.

Saju is the four-pillar dataset of your year, month, day, and hour of birth, written as eight characters in the Heavenly Stems and Earthly Branches system. Those eight characters are also called palja.

The calculation step relies on perpetual-calendar data, so a human and an AI produce the same chart. The interpretation step uses a model trained on classical Saju principles, giving more consistent readings than an off-the-cuff human interpreter — though no system can deliver deterministic predictions.

Hwajodang is currently in members-only beta. Sign in with Kakao or Google to enter your birth details and receive a reading.

One reading costs 20 credits, and 1 credit equals 100 KRW — so a single reading is 2,000 KRW. Credit bundles include bonus credits on top.

Domestic users pay by card or mobile-pay through PortOne's Toss channel; international users pay via Gumroad. Credits are added automatically once payment clears.

Unused credits can be refunded subject to our refund policy. See the refund page for the exact terms.

Without the hour pillar, accuracy drops for late-life, offspring, and fine-grained personality cues. The remaining three pillars still support a meaningful broad reading.

Either is fine. Saju is calculated by solar terms, so a solar birth date produces the same chart as the corresponding lunar date.

Ohaeng is the five-element system — wood, fire, earth, metal, water — used to classify the energies of nature and of people. Saju reads a chart's balance through its generating and overcoming cycles.

Yongsin is the key element or character that restores balance to a chart — supplementing what is scarce or moderating what is excessive. It anchors the direction of the reading.

Every reading is saved to your history and can be reopened anytime. You can also generate a share link to send a reading to someone close.

No. Saju maps innate temperament, the relative strength of the five elements, and the seasonal flow of energies. Choices remain yours, and Hwajodang's readings avoid deterministic claims.

Korean and English are both supported. Saju terms appear in romanized form alongside the original Korean so readers new to four-pillars astrology can follow without prior background.
