Terms of Service

Last updated: June 27, 2026

1. About these Terms

These Terms of Service govern your use of YomuKana ("YomuKana", "we", "us"), a web application for studying the Japanese language. By creating an account or using the service, you agree to these Terms. If you do not agree, do not use YomuKana.

2. Who we are

YomuKana is operated independently.

3. Eligibility

You must be at least 18 years old to use YomuKana.

4. Your account

Access is via email with a one-time verification code (OTP). You are responsible for keeping access to your email and for activity on your account.

5. The service

YomuKana provides Japanese study tools (kana, kanji, and flashcards). Features may be added, changed, or removed over time. The service is free and ad-supported.

6. User content

You may create your own content (such as text decks and cards). This content is yours. You represent that you have the right to use the content you add and are solely responsible for it. You grant us a limited license to store, process, and display this content back to you, for the purpose of operating the service (including sync). Your content is private — we do not make it public. We may remove content that violates these Terms or the law.

7. Acceptable use

You agree not to:

  • use the service for unlawful purposes;
  • attempt to bypass limits or security;
  • overload or interfere with the infrastructure;
  • add content that infringes the rights of others.

8. Intellectual property

YomuKana, its brand, design, code, and own learning content belong to us and are protected by law. These Terms do not transfer any of those rights to you.

9. Availability and disclaimer of warranties

The service is provided "as is", without warranty of uninterrupted operation, freedom from errors, or continuous availability. We do not offer an uptime guarantee (SLA).

10. Changes and discontinuation

We may change, suspend, or discontinue the service (in whole or in part) at any time, with reasonable prior notice where possible.

11. Limitation of liability

The service is free. To the maximum extent permitted by law, we are not liable for indirect damages, loss of data, or lost profits arising from the use of (or inability to use) the service.

12. Termination

You may close your account at any time (deletion is available in the app). We may suspend or terminate accounts that violate these Terms.

13. Changes to these Terms

We may update these Terms. Material changes will be signaled by the "last updated" date. Continued use after a change means acceptance.

14. Governing law and venue

These Terms are governed by the laws of Brazil, with the consumer's domicile elected as the venue for resolving disputes, as applicable.
