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.

What it does

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.

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.

Classical source texts

Classical Chinese chart logic, preserved in its own terms.

Cinnabar keeps the original Chinese chart language visible — the Four Pillars, ten gods, hidden stems, luck cycles, and classical checks — then translates the meaning into modern English.

A mirror for decisions, not a command to obey.

Cinnabar gives language to timing, temperament, pressure, and pattern. It is built for self-reflection, not fatalism.
