Policy
1. Basic Policy
Javaのジャ！ ("the App") is an iPhone study app designed to support preparation for Java Silver SE 17. The App respects user privacy and does not collect, store, or share personal information as a basic principle.
2. Information We Do Not Collect
The App does not collect the following information in a way that is sent externally.
- Personal information such as name, email address, or phone number
- Location information
- Contacts
- Photos, videos, or microphone input data
- Advertising identifiers
- Usage analytics data
- Purchase information
3. Data Stored Within the App
For usability purposes, the following data may be stored locally on the device.
- Chapter progress
- Answer history for each question
- Daily study records
- Study streak count
- Unlocked achievements
- Theme settings
- Code font size settings
- Study schedule input values
All of this information is stored only on the user's device and is never sent to the developer or to any third-party server.
4. Calendar Integration
The App includes an optional feature that allows users to register study schedules in the device calendar. Calendar access is requested only when the user chooses to use that feature.
- The App can create daily, weekly, or monthly study events
- The App can update or delete the study events that it manages
- Calendar data is not sent to the developer or to external servers
- The main learning features remain available even if Calendar access is not granted
5. Network Behavior
The App is designed as an offline-first app that keeps question data and study history on the device. Standard OS behavior may still occur when opening external links or interacting with Calendar features.
6. Sharing with Third Parties
The App does not provide, sell, or share user information with third parties.
7. Children's Use
The App is educational in nature, but it does not intentionally collect personal information from children.
8. Security
Study records and settings are stored on the device. However, the developer cannot completely prevent exposure caused by device loss, theft, or access by others. Please manage the security of your device appropriately.
9. Changes to This Policy
