The full licence text of every package above, and of the open-source packages they depend on, is published with Cluevora at /third-party-licenses.txt. Where a package offers a choice of licences (jszip: MIT or GPL-3.0-or-later), Cluevora uses it under the MIT licence.

Image processing on our server uses sharp and its libvips binaries (LGPL-3.0-or-later). They run only on our server and are not distributed to you.

Fonts

Cluevora serves these fonts itself, under the SIL Open Font License 1.1. Geist and Source Serif 4 are also included in the PowerPoint package, each with its licence text beside it.

The homepage and the sales page also serve these fonts themselves, under the SIL Open Font License 1.1; their licence texts are published with Cluevora at the address above.

The Book Cover Studio also serves these title fonts itself, each under the licence shown; their licence texts are published with Cluevora at the address above.

Cluevora artwork — not third-party

The Cluevora artwork library — the suspect portraits, evidence and landmark objects, floor textures and symbols, the Kids Mystery Edition props and characters, and the Book Cover Studio shapes and illustrations — is proprietary product content supplied with Cluevora. It was produced for Cluevora with the assistance of image-generation tools, and Cluevora keeps a record of how each asset was produced. It is not open-source, is not covered by any of the licences above, and is not licensed as standalone asset content.

You may use it inside the finished pages and books you create, but not as standalone files, as set out in the Terms of Use & License and summarised on the Commercial Use page.
