八字 Bazi

A clean, privacy-respecting BaZi (Four Pillars of Destiny) charting tool. - Complete charts: four pillars, hidden stems, ten gods, life stages, void branches, nayin, and symbolic stars - with solar and lunar (including leap month) input, and both late-Zi-hour conventions. - Luck cycles: decade luck pillars, annual and monthly influences at a glance. - Fully on-device: all calculations run locally. Birth data never leaves your device. No accounts, no ads, no analytics. - Optional AI readings (bring your own key): configure your own OpenAI / Anthropic (or compatible endpoint) API key and the app sends the current chart directly to your chosen provider for a traditional interpretive reading. Keys stay in the system secure storage; requests never pass through our servers. Note: content is cultural and folklore reference, provided for entertainment only. It is not health, financial, legal, or other professional advice.
