Terms of use

Last updated: October 11, 2026

By using KanaGO! you agree to these terms. If you don't agree, please don't use the app.

Using the app

KanaGO! is a tool for studying Japanese on your own. You may use it for your personal learning. Bulk-extracting its content, reselling it or using the app for unlawful purposes is not allowed.

Educational content

We take care with the content, but it may contain mistakes. It is provided as is, with no guarantee of accuracy or exam results. If you find an error, let us know via Support.

JLPT mock tests

The mock tests are unofficial practice in the exam's format. The certificate shown in the app is a keepsake of your progress and has no official value. JLPT (Japanese-Language Proficiency Test) is a trademark of The Japan Foundation and Japan Educational Exchanges and Services (JEES); KanaGO! is not affiliated with them.

Songs and videos

Videos play through the YouTube player and belong to their owners. Their use is subject to YouTube's terms. Lyrics are shown in short excerpts for educational purposes.

Your progress

Your progress is stored only on your iPhone. We can't recover it if you delete the app or lose your device.

Liability

To the extent permitted by law, KanaGO! and its author are not liable for damages arising from use of the app.

Intellectual property

The KanaGO! name, Kana-chan, the logo, illustrations, sounds and app design belong to KanaGO!. We grant you a personal, limited, non-transferable license to use them within the app. You may not copy, modify or distribute them outside it.

App Store and Apple

If you download KanaGO! from the App Store, Apple's Licensed Application End User License Agreement (EULA) and the App Store terms also apply. These terms are between you and KanaGO!, not Apple: Apple is not responsible for the app or its content, has no obligation to maintain or support it and is not liable for claims related to it. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them.

Changes

We may update these terms; the new version will be posted on this page with its date.
