三、权限使用说明

当前版本仅使用以下两项系统能力，均不需要用户在弹窗中授予敏感个人信息权限，也不涉及数据上传：

窗口隐私（PRIVACY_WINDOW）：应用切到后台时，系统会隐藏任务卡片中的应用预览画面，防止屏幕切换或多任务界面中露出学生姓名、考勤等敏感内容。
生物识别（ACCESS_BIOMETRIC）：用于进入应用时验证机主身份（锁屏密码、指纹或人脸）。验证过程由系统在本机完成，应用不采集、不存储生物特征信息。

四、第三方服务与数据共享

当前版本不接入第三方 SDK、广告服务、统计服务、账号服务、支付服务或云同步服务，也不会向任何第三方共享、传输学生或班级数据。若后续版本新增第三方服务或联网能力，我们会在上线前更新本政策，并在应用或应用市场页面中说明服务名称、用途和数据处理范围。

五、学生数据与未成年人保护

学生姓名、考勤、点评等属于敏感教育数据。本应用将其默认仅保存在设备本地，并通过应用锁和后台隐私遮罩降低泄露风险。使用本应用的教师应注意：

仅在合法的教育管理用途内录入和使用学生信息，遵守所在学校的规定及学生监护人的知情要求。
不要将包含学生个人信息的备份文件或导出内容发送给无关第三方或公开传播。
在出售、转让、维修设备或卸载应用前，先删除应用数据或妥善处理本地备份文件。

六、数据查看、更正、删除与备份

查看：用户可在应用内查看班级、学生、考勤、点评、作业和时间线等全部数据。
更正：用户可在应用内直接修改学生信息、修正考勤与点评记录。
删除：用户可删除单个学生或记录，也可通过系统设置清空应用数据或卸载应用。
备份与恢复：用户可主动创建本地备份文件，并在需要时恢复；恢复前应用会校验备份完整性并要求二次确认。

七、政策变更

八、联系我们

Class Teacher Workbench Privacy Policy

Class Teacher Workbench is a local classroom management tool for head teachers. Version 1.0.0 does not require account registration, does not connect to the internet, does not provide cloud sync, does not integrate advertising, analytics, payment, or third-party SDKs, and never uploads class or student data.

1. Basic Information

App name: Class Teacher Workbench (班主任管家)
Bundle name: com.xmgod.teachersworkbench
Version: 1.0.0
Contact email: tomkuku588@gmail.com
Effective date: 2026-09-20
Last updated: 2026-09-20

2. Information We Process

Information type	Processing	Purpose	Storage	Retention
Account and identity information	Not collected	This version does not provide account registration or login	Not applicable	Not applicable
Class and student data (names, student IDs, groups, contacts, attendance, comments, homework records, event timeline, and similar content)	Processed locally	Lets the teacher manage classes, take attendance, record comments, review the timeline, and view statistics on the device	Local app sandbox database on the device	Until the user deletes the data in the app, clears app data, or uninstalls the app
Imported CSV/Excel student roster files	Triggered by the user	Parsed locally to create student records in bulk; file contents are never uploaded	Local app sandbox on the device	Parsed results are saved as local student data; the original files are managed by the user

3. Permission Use

This version uses only the two system capabilities below. Neither requires the user to grant access to sensitive personal information in a dialog, and neither involves data uploads:

Privacy window (PRIVACY_WINDOW): when the app moves to the background, the system hides the app preview in the task card so that student names, attendance, and other sensitive content are not exposed in the recent-tasks screen.
Biometric authentication (ACCESS_BIOMETRIC): used to verify the device owner (screen-lock password, fingerprint, or face) when entering the app. Verification is completed by the system on the device; the app does not collect or store biometric data.

This version does not request other system permissions such as network, location, contacts, camera, microphone, photos, calendar, Bluetooth, or background running.

4. Third-Party Services and Data Sharing

This version does not integrate third-party SDKs, advertising, analytics, account services, payment services, or cloud sync, and does not share or transmit student or class data with any third party. If a later version adds third-party services or online capabilities, this policy will be updated before release and will describe the service name, purpose, and data scope in the app or app store listing.

5. Student Data and Minors

Student names, attendance, and comments are sensitive education data. The app stores them locally on the device only, and reduces exposure risks with the app lock and the background privacy shield. Teachers using the app should:

Enter and use student information only for lawful classroom management purposes, and follow school rules and guardians' expectations.
Not send backup files or exported content that contain student personal information to unrelated third parties or share it publicly.
Delete app data or handle local backup files properly before selling, transferring, or repairing the device, or uninstalling the app.

6. Access, Correction, Deletion, and Backup

Access: users can view all class, student, attendance, comment, homework, and timeline data in the app.
Correction: users can edit student information and fix attendance or comment records directly in the app.
Deletion: users can delete individual students or records, or clear app data through system settings or uninstall the app.
Backup and restore: users can create local backup files and restore them when needed; the app verifies backup integrity and asks for confirmation before restoring.

7. Policy Updates

If a later version adds accounts, online features, cloud sync, analytics, advertising, payment, third-party SDKs, or new system permissions, this policy will be updated before release. The updated policy will be available on this page or through the in-app entry.

8. Contact Us

Users may contact us at tomkuku588@gmail.com, or submit feedback through app store comments or the feedback entry. For privacy-related issues, please do not submit sensitive personal information such as student names, identity documents, precise addresses, or contact details in public comments.
