Privacy Policy

What we collect

• Birth information (date, optional time, optional gender, optional nickname) — required to calculate your Four Pillars.
• Reading output — your computed pillars and the AI report, cached so you can revisit it from the link we give you.
• Payment metadata — for the paid Premium (life-arc) report only, order ID, status, and amount, received from Toss Payments. We do not store your card number or billing address.
• Account info (optional) — only if you sign in to save your readings, via Google, Kakao, Naver, or email. Email sign-up stores your email address and an encrypted password.
• Anonymous analytics — aggregate page views and usage stats so we can improve the product.

What we don't collect

You do not need an account to calculate a reading or view a report. We do not collect your full name, address, phone number, or any contact information unless you submit it through our Contact form.

How we use it
