In short: the fonts and open-source components the game uses are listed here under their licenses; the models, art and sound are our own work.

2. Art, models and sound
The 3D models of the towers, castles, units, props and battlefields are made by us in Blender. The sound effects are synthesised by our own code; the music is composed in code and rendered with instrument samples from VSCO 2 Community Edition (CC0), then converted with FFmpeg. The interface icons, cards, portraits and illustrations start from AI-generated images that we clean up and colour-grade. All of this is first-party material.

4. Operations console (not part of the app)
The console our operations staff use runs only on our servers, never in the app. Its "Convert from Traditional" button uses opencc-js 1.4.2 (MIT License, Copyright © 2020-2021 The nk2028 Project) with conversion dictionaries from opencc-data (Apache License 2.0, from the OpenCC project); the conversion runs in the operator's browser and no text is sent to any outside service.
