| AI-illustrated stickers (`stickers/`, `previews/`) | [PolyForm Shield 1.0.0](LICENSES/PolyForm-Shield-1.0.0.md) |

**In plain words:** you may use, copy, modify and share the stickers for any purpose, including commercial ones, **except to provide a product that competes with Mingji** (a bird-watching, bird-identification or bird field-guide app, website or service), whether paid or free. Publications, teaching, research, museums, games, merchandise, personal projects and apps in other fields are all fine. This summary is for convenience; the license text is what counts.

**简单说：** 贴纸可以用于任何用途，包括商用、复制、修改和再分发，**唯一的例外是做与鸣迹竞争的产品**（观鸟记录、识鸟或鸟类图鉴类的App、网站或服务），收费免费都算。出版、教学、科研、博物馆、游戏、文创、个人项目和其他领域的App都可以用。以上只是便于理解的概括，以许可证原文为准。
