Licenses and credits
KanjiLock is built on work by other people. This page lists what it uses and under which terms. The app shows the same list in Settings, Sources and licenses.
KanjiLock source code
The app's source code is released under the MIT license. It covers the code only. The dictionary, the example sentences and the fonts have their own licenses, listed below.

About the dictionary content
Meanings, readings and example sentences come from community dictionaries and are shown as they are. They can have mistakes, so don't rely on them for anything important like legal, medical or official translations. The dictionary includes adult vocabulary. Words tagged vulgar, derogatory or sensitive are left out of the random daily word.
JMdict and KANJIDIC2
This application uses the JMdict/EDICT and KANJIDIC 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.

Only English meanings, the first three senses, up to four alternate spellings and one short example sentence per entry are kept. The resulting database is a derived work and is shared under the same CC BY-SA 4.0 license. You can get it from the source repository or extract it from the APK.
Tatoeba example sentences
Example sentences come from the Tatoeba Project under CC BY 2.0 FR. Each sentence in the app links to its page on Tatoeba, where its authors are credited.
