Terms of Service

1. The license we grant you

We grant you a personal, non-exclusive, non-transferable, revocable license to download and use Sekana on devices you own or control, for your own personal, non-commercial kanji learning. All rights not expressly granted are reserved.

2. Your account and conduct

You can use Sekana without an account. If you choose to sign in with Google or Apple to back up your progress, you are responsible for keeping access to that sign-in secure. You agree not to misuse the app, including attempting to reverse-engineer, decompile, disrupt, or gain unauthorized access to it or its services, or using it in violation of any applicable law.

3. Ownership

Sekana, its name, logo, mascot, user interface, original text, and software are owned by the Sekana project and protected by intellectual property laws. These Terms do not transfer any ownership to you.

4. Kanji data & attributions

Sekana builds on established, openly-licensed Japanese-language datasets. We gratefully acknowledge and attribute:

• KANJIDIC2 and JMdict/JMnedict: © the Electronic Dictionary Research and Development Group (EDRDG), used under the Creative Commons Attribution-ShareAlike 4.0 license.
• KanjiVG (stroke-order data): © Ulrich Apel and the KanjiVG project, used under the Creative Commons Attribution-ShareAlike 3.0 license.
• KanjiNetworks etymology: © Lawrence J. Howell and Hikaru Morimoto, shown with attribution where used.

These datasets remain the property of their respective authors under their own licenses. Kanji, readings, and dictionary content are reference material, not our original work.

5. A free, ad-supported app

Sekana is free to use and is supported by advertising provided through Google AdMob. Your use of ads is also subject to Google’s terms and policies. See our Privacy Policy for how advertising and your choices work.

6. Educational tool, no guarantees

Sekana is a study aid. While we strive for accuracy, we do not warrant that its content is complete, correct, or suitable for any particular purpose (including exam preparation), and learning outcomes are not guaranteed.

7. Disclaimer & limitation of liability

Sekana is provided “as is” and “as available,” without warranties of any kind, to the fullest extent permitted by law. To the maximum extent permitted by applicable law, the Sekana project will not be liable for any indirect, incidental, or consequential damages arising from your use of, or inability to use, the app. Nothing in these Terms limits rights that cannot be limited under the law that applies to you.

8. Changes

We may update Sekana and these Terms over time. When we make material changes to these Terms we will update the “Last updated” date above. Continued use of the app after changes take effect means you accept the updated Terms.

9. Governing law

These Terms are governed by the laws of the Republic of Türkiye, without regard to conflict-of-laws rules, except where mandatory consumer-protection laws of your country of residence apply.
