Terms of Use

Last updated: September 27, 2026

1. Agreement to Terms

By accessing or using the Tanu app, website and related services (the "Service"), operated by Tanu ("we," "us," or "our"), you agree to be bound by these Terms of Use. If you do not agree with these Terms, you may stop using the Service at any time.

2. Description of Service

Tanu is a language learning app that teaches Japanese through short clips of real videos, with tappable subtitles, word explanations, saved words, flashcard reviews and progress tracking. Features and availability may change as we develop the product.

3. Eligibility

You must be at least 13 years of age to use the Service. By using the Service, you represent that you meet this requirement. If you are under 18, you confirm that you have your parent or guardian's consent.

4. Accounts and Registration

When you create an account, you agree to provide accurate and complete information. You are responsible for maintaining the security of your account credentials and for all activity under your account.

5. Subscriptions and Free Trial

• Tanu offers monthly and yearly subscriptions. Prices are shown in the app, in your local currency, before you purchase.
• Free trial. The yearly plan may include a 7-day free trial. Unless you cancel at least 24 hours before the trial ends, the subscription begins and your Apple ID (or Google account) is charged. A free trial is available once per Apple ID or Google account.
• Automatic renewal. Subscriptions renew automatically at the same price at the end of each period unless cancelled at least 24 hours before the period ends.
• Cancellation. You can cancel at any time in your App Store (or Google Play) subscription settings. You keep access until the end of the current paid period.
• Payments and refunds are processed by Apple or Google under their terms. Refund requests are handled by them (for Apple: reportaproblem.apple.com).
• If prices change, you will be notified in advance as required by the App Store or Google Play, and you may cancel before the new price applies.

6. Acceptable Use

You agree not to:

• Use the Service for any unlawful purpose or in violation of these Terms
• Attempt to gain unauthorized access to any part of the Service
• Interfere with or disrupt the Service or its infrastructure
• Reproduce, distribute, or create derivative works from our content without permission
• Use automated systems to access the Service in a manner that exceeds reasonable use

6.1 YouTube Content and Premium Features

Tanu integrates content from YouTube as part of its learning experience. We want to be explicitly clear about the following:

• By using Tanu's YouTube-related features, you agree to be bound by the YouTube Terms of Service.
• All videos are hosted on YouTube and belong to their respective creators. Tanu does not claim ownership of any YouTube content displayed through our Service.
• All YouTube content in Tanu is displayed using YouTube's official embedded player, in line with YouTube's Terms of Service and embedded player requirements. We keep the standard YouTube player functionality and branding as required by YouTube's terms.
• Tanu does not charge for or sell access to YouTube videos. Our subscription fees are exclusively for Tanu's premium language learning features, which include but are not limited to:
  • One-tap word meanings, readings and explanations
  • Clips chosen for your level and interests
  • Saved words and flashcard reviews
  • Daily goals, streaks and progress tracking
  • Search and saved clips
• The YouTube content remains freely accessible on YouTube, and our premium features are designed to enhance the learning experience by providing additional educational tools around this content.

7. Learning Content

Subtitles, translations, readings and word explanations are prepared with automated tools and reviewed where possible, but they may contain errors. Tanu is a learning aid and not a certified translation or exam-preparation service. Videos may become unavailable if their creators remove them.

8. Intellectual Property

All content, features, and functionality of the Service created by us, including text, graphics, the Tanu character and artwork, logos, and software, are owned by Tanu and protected by copyright, trademark, and other intellectual property laws. You may not use our branding or content without prior written consent. YouTube videos remain the property of their creators (see section 6.1).

9. Feedback

If you send us ideas, suggestions or feedback, we may use them to improve the Service without any obligation to you.

10. Termination

You may stop using the Service and delete your account at any time in the app (Settings → Delete account). Deleting your account does not cancel an active subscription; please cancel it in your App Store or Google Play settings. We may suspend or terminate accounts that materially or repeatedly violate these Terms.

11. Disclaimers

The Service is provided "as is" and "as available" without warranties of any kind, express or implied, to the fullest extent permitted by law. We do not guarantee that the Service will be uninterrupted, error-free, or secure. Language learning results may vary.

12. Limitation of Liability

To the fullest extent permitted by law, Tanu shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the Service. Our total liability shall not exceed the amount you paid to us in the 12 months preceding the claim.

13. Your Consumer Rights

Nothing in these Terms excludes, restricts or modifies any rights or remedies you have under consumer protection laws that cannot be excluded, including, for users in Australia, the Australian Consumer Law.

14. Changes to Terms

We may update these Terms from time to time. We will notify you of material changes by posting the updated Terms on this page with a new "Last updated" date, and in the app for significant changes. Continued use of the Service after changes constitutes acceptance.

15. Governing Law

These Terms are governed by the laws of the United States. Any disputes shall be resolved in the courts of competent jurisdiction. This does not remove any rights you have under the mandatory laws of the country where you live.
