Privacy Policy

Introduction

Kanjiru (“we”, “our”, or “us”) is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use the Kanjiru mobile application.

Information We Collect

• Account Information: When you sign in with Apple or Google, we receive your name and email address (if you choose to share them). Apple Sign-In allows you to hide your email using a private relay address.
• Learning Progress: Your kanji study progress, quiz scores, game results, vocabulary mastery levels, and streak data are stored to personalize your learning experience.
• App Preferences: Settings such as theme preference, notification preferences, and display options.
• Usage Data: Anonymous analytics about which features you use to help us improve the app.

iCloud Sync

If you enable iCloud Sync, your learning progress and preferences are stored in your private iCloud account using Apple's CloudKit framework. This data is encrypted and only accessible by you through your Apple ID. We do not have access to your iCloud data.

In-App Purchases

Subscription and purchase data is handled entirely by Apple through the App Store. We receive confirmation of your subscription status but do not process or store payment information such as credit card numbers.

Third-Party Services

• Apple Sign-In: Authentication is handled by Apple. See Apple's privacy policy at apple.com/privacy.
• Google Sign-In: If you sign in with Google, authentication is handled by Google. See Google's privacy policy at policies.google.com/privacy.
• Apple App Store: Subscription billing and management is handled by Apple.

Data Storage & Security

Your learning data is stored locally on your device and, if iCloud Sync is enabled, in your private iCloud container. We use industry-standard security measures to protect your information. Local data is stored in an encrypted SQLite database.

Data Retention & Deletion

• You can reset your learning progress at any time from Settings.
• You can delete your account and all associated data by signing out and resetting all progress in Settings.
• If you delete the app, all locally stored data is removed. iCloud data can be managed through your device's iCloud settings.
• To request complete data deletion, contact us at hello@kanjiru-app.com.

Children's Privacy

Kanjiru is suitable for users of all ages. We do not knowingly collect personal information from children under 13 beyond what is necessary for the app's educational functionality. If you are a parent or guardian and believe your child has provided personal information, please contact us at hello@kanjiru-app.com.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by updating the “Last updated” date at the top of this policy. Continued use of the app after changes constitutes acceptance of the updated policy.
