# Client licensing

The first-party client code in desktop/, mobile/, ui/, mac/, mac-direct/, browser-extension/ and network/, and first-party world.linghang/transportproof code in work/linghang-channel-proof-v1/proofcodec/, is licensed under GNU General Public License version 3 only (GPL-3.0-only). This grant is made under the project owner’s explicit authorization; it does not invent a company, copyright owner or transfer of ownership.

Original third-party code, libraries, rules, assets and templates retain their own licenses and copyright notices. See each upstream LICENSE/NOTICE and the distributed dependency inventories. The seven controlled module trees retain their upstream licensing; this statement does not relicense third-party code.

Independent business backend, server administration, deployed configuration, private keys, account/device credentials and user data are outside this client grant and source distribution. Complete Corresponding Source must accompany the same distributed version; displaying this license is not a substitute.

The explicitly bundled stateless helpers server/device-proof.mjs, server/browser-channel-proof.mjs and server/profile-authorization.mjs are included under the same GPL-3.0-only grant for interface/cryptographic test reconstruction. This does not include the independent server execution-decision service, account business logic or any deployed signing material.
