The Moj Glosik app (mojglosik.pl) uses open symbol collections. We thank their authors — without their work, augmentative and alternative communication (AAC) would not be this accessible. Below is the full required attribution.
The symbol collections may also be used in commercial products, provided the authors and the licence are credited (which we do on this page) and any modifications to the symbols are published under the same licence. The symbols remain the work of their authors and are not what is being sold in this app — the fee covers the app itself and its features. If we ever modify a symbol, we will publish it publicly under the CC BY-SA licence.
