This site is built with the work of people who published it under open licences. The lists below name every asset that needs a credit, with a link to its source and to its licence terms, and the pages it appears on. Every list is generated from the same records we check when a file is added, so it stays complete.
About the photographs
The photographs show Guwahati, the Brahmaputra, Assam and chart screens as context, with a colour treatment applied. They are stock photographs. None of them shows Excel Traders Academy’s classroom, students, trainers or results: our own photographs and videos are labelled as ours wherever they appear.
About the fonts
Anton, Geist, Geist Mono, Noto Sans Devanagari and Noto Sans Bengali are licensed under the SIL Open Font License 1.1. The OFL lets anyone use, study, modify and redistribute the fonts freely as long as they are not sold by themselves, and the font files served by this site keep their original names and copyright notices.
Icons and software
Icons and the libraries that run the games, quizzes and forms are used under permissive licences (MIT, ISC, Apache 2.0 and CC0), which require only that their copyright and licence notices are kept. Those notices follow, together with the other open-source software that reaches your browser.
