Saju Letter: Korean Horoscope

Saju Letter is your daily horoscope, written as a short letter. Every morning one sealed letter arrives, starting from your own birth chart: the day you were born, read against today through Korean astrology called saju (사주).

Saju is the Korean branch of the four pillars tradition and a close cousin of BaZi. A zodiac sign describes a fixed type. Saju looks at how your birth chart meets each calendar day, so the letter is new every morning.

WHAT YOU GET
• A sealed letter every morning, sized for a coffee break. No jargon, no doom, no "lucky numbers"
• Write back: tell Dain, your letter writer, about your day and get a reply the same day
• Compatibility with a friend or partner, one link away. They don't need the app to see the result
• Your Letterbox: daily, weekly and month-end letters in one place
• A monthly calendar of your letters
• My story: your streak, and a new chapter from Dain every month
• Available in English, Spanish, Japanese and Korean

HOW IT'S MADE
Your birth chart is calculated by code, not by an AI, so nothing about your saju is invented. An AI only turns the already-computed reading into plain, kind language, under strict rules: no predictions, and no medical, legal or financial advice.

A NOTE
Saju Letter is for reflection and entertainment. It is not a substitute for professional advice. Ages 16 and up. Your birth date and time are encrypted and never shared.
