TAKUMI Japanese

Privacy Policy

This Privacy Policy explains how TAKUMI collects, uses, and protects information when you use the TAKUMI mobile application and related services.

Last updated: May 6, 2026

1. Overview

TAKUMI is a Japanese learning app focused on JLPT study content. The app delivers lesson and practice content, app notices, app version update information, and advertising configuration through its API. It also includes a report or feedback feature that lets users send issue reports to the developer.

2. Information We May Collect

Based on the app features and API used by TAKUMI, we may collect:

  • Report information you choose to submit through the app, such as title, message, and category.
  • Optional contact details you provide with a report, such as your name or email address.
  • Optional metadata sent with a report, if the app includes extra technical or contextual details to help diagnose a problem.
  • Advertising-related data that may be collected by third-party ad services such as Google AdMob.

3. How We Use Information

  • To deliver Japanese learning content for JLPT levels and sections used in the app.
  • To show public notices, announcement images, and current app update requirements.
  • To provide the app with the currently active advertising configuration.
  • To review, manage, and respond to user-submitted issue reports.
  • To maintain app stability, fix bugs, and improve the learning experience.

4. What the App API Provides

The TAKUMI app API is primarily used to deliver app content and app configuration. This includes:

  • JLPT learning content by level and section.
  • Active content version information used by the app.
  • Public notices and optional notice images.
  • App update settings such as latest version, minimum required version, update message, and store URL.
  • AdMob configuration for supported app levels.

These content and configuration endpoints are intended to operate the app experience and do not by themselves ask you to create an account.

5. Reports and Feedback

If you send a report through the app, we may store the report title, message, category, optional name, optional email address, status, and any metadata submitted with that report. This information is used only for reviewing issues, moderation, support, and product improvement.

6. Advertising

TAKUMI may show advertisements through third-party advertising partners, including Google AdMob. These partners may collect or receive information from your device and app usage in accordance with their own privacy policies in order to provide, personalize, and measure ads.

7. Data Sharing

We do not sell your personal information. We may share limited data with service providers only when needed to operate the app, such as hosting, storage, content delivery, support handling, or advertising services.

8. Data Retention

We keep information only for as long as necessary to operate the service, resolve issues, comply with legal obligations, and maintain reasonable business records. User-submitted reports may be retained for support, moderation, and debugging purposes.

9. Children's Privacy

TAKUMI is not intended to knowingly collect personal information from children in violation of applicable law. If you believe a child has provided personal information, please contact the developer so the data can be reviewed and removed where appropriate.

10. Security

We use reasonable administrative, technical, and organizational measures to protect information. However, no method of transmission or storage is completely secure, and absolute security cannot be guaranteed.

11. Your Choices

  • You may choose whether to submit a report and whether to include optional contact information.
  • You can avoid sending personal details in report text or metadata if you do not want to share them.
  • You can manage ad preferences through your device or Google account settings where available.
  • You may stop using the app at any time and uninstall it from your device.

12. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with a revised "Last updated" date.

13. Contact

For privacy questions or data requests, please contact the developer using the contact details listed on the app's Google Play listing, or replace this section with your preferred support email before publishing widely.
