# Hanzi Writer Data

The HSK simplified-Chinese stroke-animation data is extracted, only for the
characters required by KyouStudy, from `hanzi-writer-data` 2.0.1. The data is
derived from Make Me a Hanzi and, unlike the MIT-licensed Hanzi Writer runtime
code, is distributed under the **Arphic Public License**.

KyouStudy preserves the original integer and decimal coordinates and groups
them into level-specific JSON containers. The Chinese renderer only transforms
the vertical axis to match screen coordinates. The complete license text is
preserved in [`ARPHICPL.TXT`](ARPHICPL.TXT).
