Credits and licences
SupaJapa is built on open data and open-source software. This page lists each one and the licence it comes under.
Kanji and word data
SupaJapa uses the KANJIDIC2 and JMdict (EDICT) dictionary files. These files are the property of the Electronic Dictionary Research and Development Group, and are used in conformance with the Group's licence. Copyright James William Breen and The Electronic Dictionary Research and Development Group, licensed under Creative Commons Attribution-ShareAlike 4.0.
SupaJapa has corrected and shortened meanings, corrected and trimmed readings, and left some entries out. Wherever the adapted data is shown or published, in the app and on the guide pages, it is shared under the same licence. It comes with no warranty: see section 5 of the EDRDG licence and of CC BY-SA 4.0.
The kanji data came through kanji-data by David Gouveia, and the word meanings through open-anki-jlpt-decks by Jamie Sinclair. Both are MIT licensed; their notices are in the open-source notices below.
JLPT levels
The JLPT levels of the words and kanji are based on Jonathan Waller's JLPT lists at tanos.co.uk, shared under Creative Commons "BY" as its sharing page states. SupaJapa has changed some levels.
Example sentences
Many example sentences and their English translations come from Tatoeba. Tatoeba contributors wrote them, and they are licensed under CC BY 2.0 FR. They came to SupaJapa through the tatoeba-to-anki deck, and SupaJapa added furigana and audio and edited some of them. SupaJapa wrote the other example sentences.
The voice clips are made from these same words and sentences with Google Cloud Text-to-Speech, and each clip comes under the licence of the text it reads.
Icons
Uicons by Flaticon.
Open-source software
The app includes open-source code, among it React, the Supabase client, Workbox and web-vitals. Their licences and copyright notices are in the open-source notices.
