Chart calculation: iztro 2.6.3 by SylarLong, MIT License. The bundled browser engine includes dependencies; their licenses are in third-party notices.

Geographic data: Countries States Cities Database by dr5hn and contributors, retrieved 2026-10-31. Data is available under the Open Database License (ODbL). Names and hierarchy are a compact derivative; the complete derivative database is available as places.json under the same license. Coverage and administrative levels vary by location. City and region translations/native names were added from the same database on 2026-11-01; untranslated names retain the source spelling. Chinese administrative names are cross-checked by province and administrative level against Administrative-divisions-of-China (2023 data; WTFPL license). Traditional Chinese names are converted with OpenCC Python (Apache 2.0). Names are for birthplace identification, not a claim that historical or current administrative boundaries are complete.

Chart glossary: original short explanations, with terminology checked against the iztro learning documentation on palaces, stars and brightness, supporting stars, additional stars, and transformations. These are descriptions of traditional symbolism, not official or scientifically established personal assessments. Thai and English explanations are product translations. Thai place-name corrections for Fang and Long were checked against Fang Police Station and Long Police Station.

Member experience v1 adds original, transparent cross-palace reading rules and daily/monthly calculations using iztro. It is not open-ended AI chat. API references: astrolabe / surrounding palaces and horoscope / daily and monthly cycles. Calendar labels are not probability or luck scores.

Marriage-date labels (宜嫁娶 / 纳采, 月破, 八专, 杨公忌, solar terms, day-clash zodiac) come from the same lunar-javascript 1.7.7 library (6tail, MIT). 岁破 is the day branch clashing the lunar year branch. 四离 and 四绝 are the day before 立春/立夏/立秋/立冬 and 春分/夏至/秋分/冬至.
