# NebulaMap > NebulaMap (nebulamap.com) generates personalized Zi Wei Dou Shu (紫微斗數, Purple Star Astrology) readings. A visitor enters their birth date, time, and place; NebulaMap casts their birth chart and delivers a personal, palace-by-palace guidance report within minutes, in five languages. NebulaMap is a web service operated by NebulaMap Advisory (Vancouver, BC, Canada). The birth chart is computed locally from the visitor's birth date, time, and sex at birth using open-source software, then interpreted palace by palace into a clear, readable report. Every reading is generated from the individual's own chart, never a generic template. Zi Wei Dou Shu (Purple Star Astrology) is a thousand-year-old system of Chinese astrology, once reserved for the imperial court. It maps a person's life into twelve palaces (career, love, wealth, health, and more), places the major and minor stars within them, and reads how those energies unfold over time through decade and annual cycles. Everything is available in five languages: Traditional Chinese (zh-TW), Simplified Chinese (zh-CN), English (en), Japanese (ja), and Korean (ko). The chart, the report, and the terminology guide are all presented in the visitor's chosen language. NebulaMap - Trial (free): the birth chart and an overall profile overview. NebulaMap - Love / Wealth / Career / Property / Studies / Network ($10.90 USD): the one area the customer chooses, read from the natal chart through the decade cycles to the year ahead, at whatever timing resolution their question calls for. NebulaMap - Forecast ($21.90 USD): one whole lunar year, covering the tone of the year, the themes to watch, and each of its twelve lunar months in turn. NebulaMap - Complete Profile ($30.90 USD): every side of one person, in ten sections (overall profile, health, career, wealth, studies, marriage and love, friendships, family, home and property, and a closing summary). It reads the person rather than the calendar, and names no years and no decade cycles. Every paid edition can be downloaded as a PDF. The Taiwanese and Japanese landing pages price in TWD and JPY respectively. Privacy is a core commitment: a free NebulaMap - Trial report, and the birth data stored with it, is permanently deleted after 7 days. A paid report is kept under the customer's account until they choose to delete it, as is a free report on which a follow-up question has been used. Paid reports are personalized digital products delivered immediately, so sales are generally final; technical failures and duplicate charges are refunded.
