Start with an on-device face read.
Take a clear selfie. Cinnabar reads stable face proportions, brows, eyes, nose, mouth, and outline cues — without uploading the photo.
Private Chinese Birth Chart
Your Chinese birth chart. A mirror, not a fortune.
A centuries-old Chinese system for reading character and timing — computed entirely on your phone. It shows tendencies, not predictions. No account, no cloud, nothing leaves your device.
Built for reflection. Designed so your data has nowhere to go.
The difference
Privacy isn’t a setting. It’s the architecture.
Other apps ask you to trust their cloud. Cinnabar removes the cloud from the equation. Your face, birth details, charts, and readings are computed on your phone and never sent anywhere.
- No cloud
- No account
- No network
What it does
Go deeper with BaZi.
BaZi is the classical Chinese birth-chart system. Cinnabar corrects for place and solar time, builds the Four Pillars, and explains the structure in plain English.
Compare two charts.
Run a relationship reading for partners, friends, family, or work. See the spark, the friction, and the timing between two people.
Bring a real question to your chart.
Direction, work, relationships, energy, or a decision you’re sitting with — Cinnabar reflects the patterns in your own chart back to you, instead of a generic horoscope line. What you do with it is yours.
Return for one card a day.
A short note for the day — the texture of the hours ahead, and how today’s calendar rhythm meets your own chart.
Ready when you are.
