Terms of Use
These Terms of Use ("Terms") apply to the Kotomichi app ("the app"), operated by FRY Systems ("we", "us"). By using the app, you agree to these Terms. If you do not agree, please do not use the app.
1. The service
The app helps you study Japanese for the JLPT N5 and N4 levels. It is free to use and shows advertisements. This version does not offer in-app purchases.
The app is not made, endorsed, or approved by the Japan Foundation or Japan Educational Exchanges and Services, which run the Japanese-Language Proficiency Test (JLPT).
2. Who can use the app
You must be at least 13 years old to use the app. If you are under the age of majority where you live, please use the app with the permission of a parent or guardian.
3. Your account
You can use the app without an account. If you create one (with Google, Facebook, Apple, or email), you are responsible for keeping your sign-in details safe. If you think someone else is using your account, contact us. You can delete your account at any time in Settings > Account.
4. Content and license
The app and its learning materials (words, grammar notes, example sentences, questions, illustrations, and sounds) belong to us or our licensors. We give you a personal, non-transferable license to use them for your own study. You may not copy, sell, or share the materials except as the law or an applicable third-party license allows.
Third-party software, fonts, and open content are listed in Settings > Open source licenses. These components remain subject to their own licenses, which take precedence over these Terms for those components. In particular, the kana stroke-order data is derived from KanjiVG and is available under CC BY-SA 3.0; the personal-use restriction above does not limit rights granted by that license.
5. Things you must not do
You must not:
- copy, change, or redistribute the app or its materials, except as permitted by law or an applicable third-party license;
- try to break into or overload the app or our servers, or reverse engineer the app except as permitted by law or an applicable third-party license;
- use the contact form to send unlawful, abusive, or spam messages;
- use the app in a way that breaks the law or harms other people or us.
6. Advertisements and other services
The app shows advertisements provided by Google AdMob, and it uses services from other companies (for example Google, Meta, and Apple for sign-in). Those companies have their own terms. We are not responsible for advertisements or for websites you open from them.
7. No guarantee
We work to keep the materials accurate, but the app is provided "as is". We do not promise that it is free of mistakes, that it will always be available, or that you will pass any exam. We may change, add, or remove content and features.
8. Limits of our responsibility
To the extent the law allows, we are not responsible for loss or damage that comes from using the app, including lost learning records. This does not limit our responsibility for damage caused on purpose or by our gross negligence, or any rights you have under consumer protection laws that cannot be excluded.
9. Suspending or ending the service
We may stop or change the app, in whole or in part, for maintenance, problems, or other necessary reasons. If you break these Terms, we may suspend or delete your account.
10. Changes to these Terms
We may update these Terms. We will show the new effective date at the top, and we will tell you in the app about important changes. If you keep using the app after a change, you accept the updated Terms.
11. Law and disputes
These Terms are governed by the laws of Japan. Any dispute will be handled by the court that has jurisdiction over our location, unless consumer protection laws where you live give you a different right.
12. Language
These Terms are written in English. If a translation differs from the English text, the English text applies.
