All three titles are open-source and distributed under a Creative Commons Attribution-ShareAlike 3.0 license. CC-Canto and the CC-CEDICT Cantonese readings are copyright (c) 2015-16 Pleco Software Incorporated, while CC-CEDICT itself is copyrighted by its maintainers with portions from the original CEDICT database copyright (c) 1997, 1998 Paul Andrew Denisowski.
All of these titles are distributed in CC-CEDICT format (see their website for details) (though the definition formatting in CC-Canto entries is very rough and doesn't really match it well yet), with the addition of Jyutping readings after the Pinyin readings enclosed by {}.
You can download CC-Canto for our Chinese dictionary apps on iOS (App Store) or Android (Google Play / direct APK) via the in-app "Add-ons" screen; CC-CEDICT is built into the basic app download (with the Cantonese reading data integrated).
