What is in the ModAVD repository

• Everything except package/, bridge/, assets/ and the .patch files under patches/ (the README and other documents, docs/, scripts/, .github/ and so on): Apache License 2.0, see LICENSE in the repository root. Copyright 2026 qiyinxi.
• package/ and bridge/ are under AGPL-3.0-or-later (see the next section).
• Patches follow the license of the file each one changes (see the Patches section).
• The images and program icons under assets/ are covered in Icon and artwork.

The documents on this site are also published under the Apache License 2.0.

ModAVD's own programs

From 0.36.0 all of them are under the GNU Affero General Public License version 3 or later (AGPL-3.0-or-later):

Program	Source
The scripts in the package (tools\modavd-bridge.ps1, which installs the bridge; 0.38.1 and earlier also have three .bat and three .ps1 files for fetching the Google components, collecting a problem report and copying system and game info)	package/ in the ModAVD repository. The scripts in packages from 0.35.0 and earlier are published under the Apache License 2.0
The arm64 execution bridge (sdk\emulator\resources\modavd\)	bridge/ in the ModAVD repository, and also in the source bundle of the same Release
The manager ModAVD.exe and the CLI tools\modavd.exe	ModAVD/ModAVDManager
The host IME components\modavd-ime.apk	ModAVD/ModAVDHostIME

If you distribute these programs (modified or not), or put a modified version online for others to use, you must provide the corresponding source under the same license. Other programs that only call the local interface of modavd.exe, the MCP server or the manager are not affected.

Patches

Each patch is published under the license of the file it changes, consistent with the upstream file header:

• In the QEMU repository (platform/external/qemu), patches to QEMU's own files, and to files with a GPL-2.0 header, are under GPL-2.0. Patches to files with an Apache-2.0 header (some of those under android/ and android-qemu2-glue/) are under the Apache License 2.0. The license of each patch is listed in patches/BASE.md.
• The gfxstream and Crashpad patches are published under the Apache License 2.0, the same as those projects themselves.

Programs in the Release

They contain third-party components such as QEMU (GPL-2.0), FFmpeg (GPL-2.0 or later, statically linked), Qt 6.5.3 (LGPL-3.0), and GLib and libusb (LGPL-2.1). Programs such as qemu-system as a whole are published under GPL-2.0. The license of each component is in LICENSES\NOTICE.txt in the package, and a summary is in THIRD_PARTY.md.

Source code

The source bundle of the same Release (ModAVD-<version>-sources.zip) holds the complete corresponding source:

• the exact versions, at build time, of the 24 repositories compiled into the programs, one .tar.xz per repository, with the build scripts in the QEMU repository;
• the source packages of FFmpeg / libvpx / libxml2 / pixman, the SeaBIOS and iPXE source, and the Qt 6.5.3 source;
• the GLib 2.82.2 that netsimd.exe statically links, with its build modules, and the netsim source;
• two repository lists (also in manifests/ in the ModAVD repository);
• from 0.36.0 also modavd-src-<commit>.tar.xz, the source of ModAVD's own programs (the manager and CLI, the arm64 execution bridge, the host IME), published under AGPL-3.0-or-later, with LICENSE and NOTICE inside the archive;
• SOURCES.txt, which describes these files one by one.

The patches are in patches/ in the ModAVD repository. To build it yourself, see Building from source.

Google components

adb and the system images are not in the Release. 补全组件 (Fetch components) in the manager, or tools\modavd.exe components fetch, downloads them from the official channels. They are covered by the Android Software Development Kit License Agreement, which you must accept before downloading.

Icon and artwork

• The images under assets/ in the ModAVD repository (banner, avatar, social preview image), and the icons compiled into the programs (the program icons and window icons of emulator.exe, emulator-check.exe, qemu-system-x86_64*.exe and ModAVD.exe, and the images in the manager's pages), are ModAVD's own icon and artwork and are not covered by the grant of any code or document license.
• If you have a copyright concern, please contact us through Issues or by email at qiyinxi@foxmail.com, and we will deal with it immediately.
