1. Introduction

Koshakan respects user privacy. This Privacy Policy explains what information the app may process, how that information is used, and what choices users have when using the app.

2. Information We Collect

Koshakan is designed to work primarily on-device.

The current version of the app may store limited app data locally on the user’s device, including:

• saved words and bookmarks
• basic learning progress stored on-device
• app preferences and related local settings

Koshakan does not currently require account registration or user login.

3. How Information Is Used

The locally stored information is used only to support the app experience, including:

• saving bookmarked vocabulary words
• restoring learning state between sessions
• improving usability and convenience inside the app

4. Data Storage

In the current version, user data is stored locally on the device using local app storage. This means saved words and similar progress data stay on the user’s device unless the user removes the app or clears app data.

5. Data Sharing

Koshakan does not sell user data.

Koshakan does not currently share personal data with third parties for advertising or marketing purposes.
