Cinnabar

Cinnabar (朱砂) is quiet, private Chinese astrology for self-reflection. A mirror, not a fortune.

PRIVATE BY DESIGN — NOT BY PROMISE

Your birth details are about as personal as data gets. Most astrology apps quietly send them to a server. Cinnabar doesn't — it can't.

- No account, ever. Nothing to sign up for.
- No internet permission. The app has no network access, so your data physically cannot leave your phone.
- No ads, no analytics, no trackers.
- Everything is computed on-device, offline.

Nothing to upload, nothing to leak. A room of your own to think in — not a feed, not a product that watches you back.

WHY BAZI

Most astrology reads you like a headline: "you're a Leo." BaZi (八字) reads you like a fingerprint. It weaves together the year, month, day, and hour of your birth into a four pillars birth chart — a different lens from Western astrology, quieter and older, translated into plain, sharp English you can actually use. No jargon walls, no mysticism you have to pretend to follow.

WHAT'S INSIDE (four calm tabs)

- Chart — your BaZi four pillars birth chart. See who you are: your five elements, your natural temperament, and the long luck-cycle seasons (大运) and yearly flow that shape how a period tends to feel. Closer to a fingerprint than a sun sign.

- Today — a 30-second daily reading on the day's tendency, plus one small thing to try. Quiet, specific, and gone in half a minute.

- Match — compatibility (合盘) for the people who matter: partners, family, friends, and work. Why you click, where you clash, and what to try next. Not a score, not a verdict — just a clearer picture of two people meeting.

- First Look — an optional, private selfie face reading (面相). It reads facial proportions on your device only. It does not identify who you are and builds no face profile. Entirely optional, entirely local.

WHY CINNABAR

- Private by design — no network, no account, no cloud.
- On-device and offline — works anywhere, answers to no one.
- Real cultural depth — genuine BaZi, four pillars, five elements, not a watered-down horoscope.
- Plain English — thoughtful writing, no mysticism for its own sake.
- Quiet — no streaks, no push spam, no dark patterns.

WHO IT'S FOR

For anyone curious about BaZi, four pillars, Chinese astrology, or a birth chart that goes deeper than a daily horoscope. For people who journal, reflect, and want a private mirror rather than a label — and who care where their data goes.

A NOTE ON LANGUAGE

Cinnabar names tendencies and patterns. It does not tell you what will happen or hand you a destiny. It's a starting point for reflection, not an answer key — a mirror held at a thoughtful angle that shows you the shape of things, then gets out of the way. You decide what to do with it.

For self-reflection, entertainment and cultural experience. Not medical, legal, financial, or psychological advice.
