Credits & Licenses
Chitmunk stands on other people's work. Here is what we use, who made it, and what (if anything) you owe them when you sell printed cards.
Art and patterns
| Source | License | What you need to do |
|---|---|---|
| Kenney Game Assets (Board Game Pack) | CC0 | Nothing. A credit is kind but not required. |
| Hero Patterns by Steve Schoger | CC BY 4.0 | Credit it. Use: Patterns by Hero Patterns (heropatterns.com), Steve Schoger, CC BY 4.0. |
| game-icons.net (via Iconify) | CC BY 3.0 | Credit the icon authors. "Credits for art you've used" in the Clip Art Browser lists them for you. |
| Poly Haven textures | CC0 | Nothing. |
| ambientCG textures | CC0 | Nothing. |
| Google Fonts | OFL or Apache 2.0 | Nothing. These licenses allow embedding in PDFs and printed products. |
| Iconify icon sets | Varies by set | Icons come from open-source sets; each icon shows its license, and CC BY icons are collected in "Credits for art you've used". |
Fonts you upload yourself are your responsibility: check that your font's license allows embedding in PDFs and printed products you sell.
Open-source libraries
Chitmunk loads these from public CDNs when you need them. We do not redistribute them, except Yjs (which bundles lib0) and Ola, which ship with the site under their own MIT license header.
