# Third-party notices（第三方组件声明） Stronghold Protocol's own code is licensed under **GPL-3.0-or-later** (see [LICENSE](LICENSE) and [NOTICE.md](NOTICE.md)). The components below are **not** part of that grant: each stays under its own licence, reproduced at the end of this file. Nothing here is committed to the repository except `tools/local-extract/aklz4.py`; the client libraries are installed by npm and copied into `public/vendor/` by `tools/vendor.mjs` (postinstall), and the release bundle carries them (with `node_modules/`, which keeps each package's own licence file). 本项目自己的代码采用 GPL-3.0-or-later；下列第三方组件各自保留原许可证，不受 GPL 约束。 ## Software | Component | Version | Licence | Where it is used | In the repository | In the release bundle | |---|---|---|---|---|---| | [PixiJS](https://github.com/pixijs/pixijs) | 7.4.2 | MIT | browser renderer — `public/vendor/pixi.min.js` | no (npm) | yes | | [pixi-spine](https://github.com/pixijs/spine) | 4.0.6 | MIT banner; contains the **Spine Runtimes**, under the **Spine Runtimes License Agreement** (package licence "SEE SPINE-LICENSE") | Spine model playback — `public/vendor/pixi-spine.js` | no (npm) | yes | | [Preact](https://github.com/preactjs/preact) | 10.29.8 | MIT | UI — `public/vendor/preact.module.js`, `hooks.module.js` | no (npm) | yes | | [htm](https://github.com/developit/htm) | 3.1.1 | Apache-2.0 | UI templates — `public/vendor/htm.module.js` | no (npm) | yes | | [three.js](https://github.com/mrdoob/three.js) | 0.186.1 | MIT | official 3D board — `public/vendor/three.core.js`, `three.module.js` | no (npm) | yes | | [qrcode-generator](https://github.com/kazuhikoarase/qrcode-generator) | 2.0.4 | MIT | the 森空岛 binding panel renders the scan-login QR client-side — `public/vendor/qrcode.js` (a UMD build loaded as a classic script, so the global `qrcode`) | no (npm) | yes | | [ws](https://github.com/websockets/ws) | 8.22.0 | MIT | WebSocket server (`server/`) | no (npm) | yes (`node_modules/`) | | [Node.js](https://nodejs.org/) | v22.23.3 (pinned in `scripts/make-windows-bundle.mjs`) | MIT | the portable `node\node.exe` (**Windows portable package only** — the integration bundle in [Releases](../../releases/latest) ships no `node.exe`) | no (downloaded from nodejs.org at package time, sha256 verified) | **Windows portable package only** (`node\node.exe`, with `node\LICENSE-node.txt`) | | [puppeteer-core](https://github.com/puppeteer/puppeteer) | 25.12.0 | Apache-2.0 | optional browser tests (dev dependency) | no (npm) | no | | [Ark-Unpacker](https://github.com/isHarryh/Ark-Unpacker) LZ4AK decoder | — | BSD-3-Clause | `tools/local-extract/aklz4.py` (optional local extraction) | **yes** — keeps its notice; full text also in `tools/local-extract/LICENSE-Ark-Unpacker.txt` | yes | | [UnityPy](https://github.com/K0lb3/UnityPy) (via MooncellWiki/UnityPy), [lz4](https://github.com/python-lz4/python-lz4), [Pillow](https://github.com/python-pillow/Pillow) | see `tools/local-extract/requirements.txt` | MIT / BSD-3-Clause / MIT-CMU | optional local extraction; installed by pip into `.venv-extract` only when the host opts in | no | no | The Spine Runtimes License requires, among other things, that redistributions include its licence and copyright notice (reproduced below) and that "each user of the Products must obtain their own Spine Editor license" unless the integration is covered by the Spine Editor License Agreement — read it before redistributing. To allow the combination at all, this project grants an additional permission under GPL-3.0 section 7 for linking with the Spine Runtimes (see [NOTICE.md](NOTICE.md)). ## Fonts | Font | Licence | How it gets here | |---|---|---| | Bender (Jovanny Lemonad / Oleg Zhuravlev, Gladkikh Ivan) | the authors' free-font terms (not GPL) | downloaded by `tools/fetch-assets.mjs` from [TimWangZi/The-font-of-Arknights](https://github.com/TimWangZi/The-font-of-Arknights) into `public/fonts/` (included in the release bundle) | | Novecento Wide (Jan Tonellato / Synthview) | the authors' free-font terms (not GPL) | as above | | Noto Sans SC, Oxanium, Rajdhani | SIL Open Font License 1.1 | loaded by the browser from Google Fonts at runtime; not distributed | ## Game data, art and audio All names, characters, artwork, Spine models, UI graphics, music, sound effects and game data of *Arknights* / 「卫戍协议：盟约」 are © Shanghai Hypergryph Network Technology Co., Ltd. (上海鹰角网络科技有限公司) and its licensors (Yostar and others). They are **not** licensed under the GPL and this project grants no rights to them; see [NOTICE.md](NOTICE.md) for the non-commercial terms. Community mirrors used by `tools/fetch-assets.mjs` / `tools/build-data.mjs`: [Kengxxiao/ArknightsGameData](https://github.com/Kengxxiao/ArknightsGameData), [yuanyan3060/ArknightsGameResource](https://github.com/yuanyan3060/ArknightsGameResource), [fexli/ArknightsResource](https://github.com/fexli/ArknightsResource), [isHarryh/Ark-Models](https://github.com/isHarryh/Ark-Models), [ArknightsAssets/ArknightsAssets2](https://github.com/ArknightsAssets/ArknightsAssets2) — thanks to their maintainers. The English game texts (`data/i18n/en.json`, `tools/build-i18n.mjs`) come from the official EN client tables mirrored by [ArknightsAssets/ArknightsGamedata](https://github.com/ArknightsAssets/ArknightsGamedata) (`en/gamedata`, the default source) and [Kengxxiao/ArknightsGameData_YoStar](https://github.com/Kengxxiao/ArknightsGameData_YoStar) (`en_US`, `--source yostar`); same terms as the rest of the game data. Quotations of PRTS Wiki, BWIKI, NGA, 巴哈姆特 and other community pages in `docs/` stay under the terms of their sources (the wikis' texts are CC BY-NC-SA). ## Translations The English UI strings (`public/i18n/en.json`) and the fallback game-text translations (`tools/i18n/fallback-pr70.json`) are based on GitHub PR #70 (branch `en-translation`) by **@YuriRestia**, reused with credit and released with the project under GPL-3.0-or-later (docs/I18N.md). PR #70 named ak-spa-database.pages.dev and arknights.wiki.gg as references: texts it took from ak-spa-database.pages.dev (no licence) are excluded; arknights.wiki.gg is CC BY-SA 4.0, which may be combined into a GPL-3.0 work (the one-way compatibility Creative Commons declared) — thanks to its contributors. Official game terms and names in those files remain © Hypergryph / Yostar. --- ## Licence texts ### PixiJS — MIT ```text The MIT License Copyright (c) 2013-2023 Mathew Groves, Chad Engler Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
