Privacy Policy

Yenadoku Privacy Policy

An app-specific policy tailored to a login-free, local-storage puzzle app.

1. Overview

Yenadoku is a sudoku puzzle app that works without login, storing data primarily on the device. We process only the minimum information necessary to provide the service.

2. Information stored

  • Current puzzle progress
  • Completion times, best records, and hint usage history
  • App settings such as text size, automatic memo clearing, and same-number highlighting
  • State values required for displaying ads and processing rewards

3. Information we do not collect

  • Sign-up information, user IDs, passwords, or email addresses
  • Contacts, location data, or address books
  • Server-account-based learning records

4. Third-party services

  • Google AdMob

In the course of delivering ads and operating the service, Google AdMob may process device identifiers, ad interaction data, and diagnostic data.

5. Retention and deletion

Yenadoku's progress records and settings are stored in the device's internal storage by default. Locally stored data may be deleted together when the app is uninstalled or app data is cleared.

6. Contact

For inquiries about personal information and data processing, please contact official@yenalab.com.
