The quickest way to reach us is in the app: Me → Feedback. It sends the app version with your message, so we can help faster. You can also write to privacy@cinnabar.cliffdao.com.

Do I need an account?

No. Everything works on your phone without signing in. Signing in with your email keeps your charts when you change phones.

I don’t know my exact birth time.

Choose “I don’t know my birth time”. The chart then uses the noon hour, and the app notes that palace positions are approximate.

What is true solar time?

Clock time is shared across a whole time zone, but the sun is overhead at different moments east and west. Turning on true solar time corrects your birth time for the longitude of your birth city, which can move it into a different two-hour period.

Are the readings accurate?

Readings follow the traditional rules of Zi Wei Dou Shu, and some are written by AI. They are for entertainment and self-reflection, not advice on health, money or other decisions. If a reading feels off, tell us with 👎 or in Feedback.

How do I delete my account?

Me → Account → Delete account. You may be asked to confirm with a new email code. Deletion is immediate and cannot be undone. Without an account, use Me → Clear data on this phone.

How do I cancel a subscription?

Subscriptions are billed by Apple. On your iPhone open Settings → your name → Subscriptions. Deleting the app or your account does not cancel it.

I didn’t get the sign-in email.

Check your spam folder and wait a minute before asking for a new code. Each code works for 10 minutes.
