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.
Ask your chart a real question.
Burnout, work, money rhythm, partnership, direction — each answer comes from your own chart, not a generic horoscope line.
Return for one card a day.
A focused note for the day: what to lean into, what to avoid, and how today’s calendar rhythm meets your own chart.
