Privacy Policy for Kanji Blossom

Last Updated: December 19, 2025

At Kanji Blossom, we are committed to protecting your privacy and providing transparency about the data we handle.

Data We Collect and Why

1. Personal Data
Kanji Blossom is designed to be used without requiring you to create an account or provide personally identifiable information. We do not collect this type of personal data.

2. Diagnostic Data (Crash Reports)
To improve the stability and performance of our application, we use Firebase Crashlytics, a service provided by Google Inc. If the app crashes, Crashlytics automatically collects anonymous diagnostic information. This data includes:

• A unique installation identifier (UUID) that does not personally identify you.

• The type of device and its operating system version.

• Information about the state of the app at the time of the crash.

This data is essential for us to identify and fix bugs, and it is not used for any other purpose. For more information, you can review Google's Privacy Policy and the Firebase Privacy and Security documentation.

3. Usage Data and Analytics

To verify user engagement and improve the educational value of Kanji Blossom, we utilize Google Analytics for Firebase. This service enables us to collect aggregated, anonymous data regarding how the application is used.

We monitor general usage patterns, including:

• User Engagement: Data regarding session duration, frequency of use, and retention rates.

• Learning Progression: General statistics on how far users progress through the content to help us balance difficulty levels.

• Feature Interaction: Anonymous data on navigation flows and interactions with various app screens and features. We may also use this data to test and optimize different versions of the app to improve the user experience.

This analytical data is pseudo-anonymized; it is associated with a random installation instance ID and is not linked to your identity. For further details on how Google processes this data, please refer to Google's Privacy Policy and Google Analytics for Firebase Use Policy.

You can opt out of analytics and crash reporting at any time from the app's settings.
