“快乐学堂”（以下简称“本应用”）是一款面向小学生的英语和语文学习应用，由个人开发者 jinhua xiao 开发。我们非常重视儿童隐私，本政策说明本应用如何处理信息。
本应用没有账号系统，不联网上传数据，不包含广告，不使用任何第三方统计或追踪工具。家长填写的孩子名字、年级、头像，以及学习进度、金币、奖励兑换记录，全部只保存在您自己的 Mac 上（应用沙盒目录内），开发者无法获取。
“跟我读”功能会在您允许后使用麦克风，并调用苹果系统自带的语音识别来判断孩子是否读对。
本应用面向儿童设计，遵守相关儿童隐私保护要求：不收集儿童个人信息，不向第三方提供任何数据，不包含应用内购买和外部链接。打开系统设置等离开应用的操作需要家长验证。
在应用“设置”中可以清空某个孩子的学习进度或删除孩子资料；删除本应用即会删除全部本地数据。

Effective: September 17, 2026
We do not collect any personal information. HappyLearn has no accounts, no ads, no analytics and no tracking. Children's names, grades, avatars, learning progress and reward records are stored only on your Mac inside the app's sandbox and are never sent to the developer.
Microphone & speech recognition. The read-aloud feature uses the microphone (with your permission) and Apple's built-in speech recognition to check pronunciation. Audio is not recorded or sent to the developer. Recognition runs on-device where supported; otherwise the system may send the audio to Apple for processing under Apple's Privacy Policy. You can revoke these permissions at any time in System Settings.
Children. The app is designed for children, collects no personal information from them, shares nothing with third parties, and has no in-app purchases or external links. Actions that leave the app require a parental gate.
