# Third-Party Notices

Sumbo release binaries are published as **self-contained** builds: the
`Sumbo.exe` you download bundles the .NET runtime and Windows Desktop
(Windows Forms) runtime alongside Sumbo's own code. Those runtime
components are third-party software and are redistributed under the
following terms.

Sumbo itself is licensed under the MIT License — see [LICENSE](LICENSE).

## Acknowledgements (no code redistribution)

- The DWM-thumbnail window-mirroring approach was inspired by
  [OnTopReplica](https://github.com/LorenzCK/OnTopReplica). Sumbo is an
  independent, from-scratch implementation and does not include or derive
  from OnTopReplica source code; this entry is an acknowledgement, not a
  license notice.
