This Privacy Policy explains how Simple Apps ("we", "our", or "us") collects, uses, and protects your information when you use our mobile applications Simple Hiragana and Simple Kanji (the "Services").
1. Information We Collect
Our applications are designed to respect user privacy. We minimize data collection to provide you with the best learning experience.
- Learning Progress & Statistics: Data regarding your study progress, quiz scores, learned characters, and custom tags are stored locally on your device.
- Authentication Information: If you choose to enable Cloud Backup with Google Drive, we authenticate you using Google Sign-In. We only access your basic profile email to identify your backup session.
- Diagnostics & Crash Logs: We may collect anonymous crash data and diagnostic information via Firebase Crashlytics to improve application stability.
2. Google Drive Data & Permissions
Google API Services User Data Policy Compliance
Our use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
When you enable the Google Drive Cloud Sync feature:
- We request access exclusively to the
https://www.googleapis.com/auth/drive.appdata scope.
- Hidden Application Data Only: This scope allows the app to create, read, and update only its own backup files inside a private, hidden folder in your Google Drive storage.
- No Access to Personal Files: We CANNOT view, edit, access, or delete your personal files, photos, documents, or any other folders in your Google Drive.
- No Data Sharing: Your backup data is never shared with third parties or stored on external proprietary servers; it remains strictly between your device and your personal Google Drive account.
3. Third-Party Services
We may use trusted third-party service providers to support our operations:
- Google Identity & Google Drive API: For optional cloud backup and authentication.
- Firebase (Google LLC): For analytics, crash reporting (Crashlytics), and app stability monitoring.
4. Data Retention and Deletion
You have full control over your data:
- Local Data: You can reset or delete your local progress anytime by clearing app data in Android Settings or uninstalling the application.
- Cloud Backup Data: You can delete your cloud backup directly from the application settings or by managing connected apps in your Google Account security settings.
5. Children's Privacy
Our applications do not knowingly collect personally identifiable information from children under the age of 13. If you believe your child has provided us with personal information, please contact us so we can take appropriate action.
6. Changes to This Privacy Policy
We may update our Privacy Policy periodically. Any updates will be posted on this page with an updated revision date.
