The complete Everything SDK, Dear ImGui, Lua, pinyin-data, Font Awesome,
Microsoft Fluent System Icons and MinHook license texts are retained under
their corresponding third_party/ directories. All are copied into the
licenses directory of release packages. The Font Awesome font is distributed
under the SIL Open Font License 1.1 with the reserved font name
"Font Awesome".
The Microsoft Windows App SDK runtime is redistributed self-contained under
the license terms and third-party NOTICE installed by the pinned 2.4.0 NuGet
package. The build records those files in SnowDesktop.deployment.json, and all
release packagers copy them to the payload licenses directory. The pinned
Windows ML 2.1.74 and WebView2 1.0.3719.77 licenses and third-party notices are
copied the same way, along with the Microsoft.Windows.CppWinRT 3.0.260818.1 MIT
license.
SnowDesktop uses MiSans and HarmonyOS Sans as optional interface fonts. They are
separate licensed assets, not GPL-licensed SnowDesktop code. Their original OTF/TTF
files are bundled unchanged with SnowDesktop; no glyph subsetting, conversion,
or font redevelopment is performed. The full agreements are retained in
third_party/misans/LICENSE.pdf and third_party/harmonyos-sans/LICENSE.txt and
copied into release payloads as MiSans-LICENSE.pdf and
HarmonyOS-Sans-LICENSE.txt. These fonts may not be redistributed as standalone
font products. The font settings and About page identify their use and owners.
SnowDesktop 使用 MiSans 与 HarmonyOS Sans 作为可选界面字体,字体资源分别适用 自己的许可,不适用 SnowDesktop 源码的 GPL 许可。仅随应用分发原始 OTF/TTF 文件, 不进行字形裁剪、转换或字体再开发;保留完整协议并随发行包交付。禁止将这些字体 作为独立字体产品再次分发。字体设置与关于页面标明使用的字体和权利人。
YASB references and adapted portions are documented separately in
third_party/yasb/README.md, pinned to
d6d1e6d553b0aac34fd5fb34928d3ca82b8d055f. Copyright (c) 2024 amnweb and
Copyright (c) 2021 denBot. Its MIT notice is retained in
third_party/yasb/LICENSE and distributed as
YASB-LICENSE.txt. The adapted private tray wire structures and Bluetooth
control approach are identified there; SnowDesktop's IPC, task service and
native presentation are separate implementations. The About page links to
the pinned upstream source.
SnowDesktop contains modified portions derived from TranslucentTB at upstream
commit 322e2b7395a51975150126276308b415970e080b. The incorporated material is
copyright TranslucentTB contributors and remains licensed under GPL-3.0-only,
the same license used by the SnowDesktop core. SnowDesktop modified the material
in 2026 for its own taskbar integration and desktop backdrop implementation.
The affected files are:
src/taskbar_dynamic/ShellViewCoordinator.idlsrc/taskbar_hook/taskview_visibility.h- portions of
src/taskbar_hook/taskbar_hook.cpp - portions of
src/app/render/desktop_backdrop_compositor.cpp
The complete GPL v3 license text is retained in the repository root LICENSE.
The upstream source and history remain available at the pinned TranslucentTB
commit linked above.
src/icons/icon_beautify.cpp adapts normalized shape control points and continuous
corner geometry from DeskMakeover's dm-icon-core shape catalog. The upstream
visual-language reference is available at
https://github.com/nicepkg/deskmakeover/blob/main/docs/specs/02-visual-language.md
and the upstream project source is available at
https://github.com/nicepkg/deskmakeover.

src/theme/flat_glass_rim.h contains modified CPU adaptations of the SDF edge-light,
opposing fan-mask and exponential inner-shadow calculations from OpenHarmony
GraphicsEffect at commit da8e11652a705ea2141c35de1a1fff501148740e.
Copyright (c) 2025-2026 Huawei Device Co., Ltd. SnowDesktop modified these
portions in 2026 for its existing opacity masks and chose its own visual
parameters. This is not an assertion that Honor MagicAnimation uses the same
implementation. The source paths and adaptation boundaries are documented in
third_party/graphics-effect/README.md. The Apache-2.0 license is reproduced
below so release packages containing this notices file retain the full text.
src/theme/flat_glass_rim.h 包含上述官方边缘光、对向扇区遮罩和指数内阴影计算的修改版。
SnowDesktop 于 2026 年将其移植到现有透明度遮罩并独立调校视觉参数,未声称与荣耀
MagicAnimation 使用相同实现。来源和移植边界见上述 README;完整许可证附于本文末尾。
steam_bridge/ can optionally be built against a separately obtained
Steamworks SDK. The SDK, its headers, import libraries, and redistributable
binary are not included in this repository and are not covered by either the
SnowDesktop GPL license or the bridge MIT license. See
steam_bridge/THIRD_PARTY_NOTICES.md for the distribution boundary.
