BabySunshine（"本应用"）是一款面向家长的婴幼儿日晒记录工具，遵循「数据最小化」原则设计。我们尽可能让您无需向我们提供任何个人信息即可使用本应用。
一、我们收集什么
我们不收集、不存储、不向任何服务器传输您的个人数据。所有宝宝档案（昵称、性别、出生日期、肤质）、晒太阳记录（日期、时长、天气、光照值）与设置均保存在您的设备本地。
唯一的例外是粗略位置：仅当您主动点击「定位到当前位置」时，本应用才会请求系统定位权限，获取的经纬度仅用于查询当地天气，不会与您的身份关联，也不会上传到我们的服务器。
二、第三方服务
查询天气与地名时，您的经纬度（不含任何身份信息）会发送给以下服务：
- Apple WeatherKit — 天气与紫外线数据（受 Apple 隐私政策约束）
- Open-Meteo.com — 天气数据备选通道（其隐私政策见 open-meteo.com）
- BigDataCloud.com — 免费逆地理编码（坐标 → 地名）
上述服务返回的天气数据仅在本机展示与存储。
三、我们不做什么
- 不使用广告标识符，不接入任何广告 SDK
- 不进行跨应用追踪，不加入任何数据经纪网络
- 不向第三方出售或共享您的任何数据
- 不包含任何用户生成内容或社交功能
四、儿童隐私
本应用不收集任何用户（包括儿童）的个人信息，符合《儿童在线隐私保护法》（COPPA）及《通用数据保护条例》（GDPR）对儿童数据保护的要求。本应用不含广告、不含应用内购买之外的第三方服务追踪。
五、您的控制权
- 所有数据仅存储在本机，您可在「设置 → 清空全部记录」中随时删除
- 卸载应用会一并删除全部本地数据
- 您可使用「导出记录（CSV）」将数据备份为自行管理的文件
六、政策变更
若本政策发生重大变更，我们将在本页面发布更新并更新生效日期。

BabySunshine ("the App") is a sun-exposure tracking tool for parents, built on a data-minimization principle. The App is designed so that you can use it without providing any personal information to us.
1. What We Collect
We do not collect, store, or transmit any personal data to our servers. All baby profiles (name, gender, birthday, skin type), sunbathing records (date, duration, weather, light values) and settings are stored locally on your device.
The only exception is coarse location: location is requested only when you actively tap "Use current location". The coordinates are used solely to look up local weather, are never linked to your identity, and are never uploaded to our servers.
2. Third-Party Services
When looking up weather and place names, your coordinates (containing no identity information) may be sent to:
- Apple WeatherKit — weather and UV data (governed by Apple's privacy policy)
- Open-Meteo.com — fallback weather channel (see their privacy policy at open-meteo.com)
- BigDataCloud.com — free reverse geocoding (coordinates → place name)
Weather data returned by these services is displayed and stored only on your device.
3. What We Do NOT Do
- No advertising identifiers, no ad SDKs
- No cross-app tracking, no data-broker networks
- No selling or sharing of your data with third parties
- No user-generated content or social features
4. Children's Privacy
The App does not collect personal information from any user, including children, and complies with COPPA and GDPR requirements for children's data. The App contains no ads and no third-party tracking beyond the services listed above.
5. Your Control
- All data stays on your device. You can delete everything at any time via "Settings → Clear All Records"
- Uninstalling the App deletes all local data
- You can back up your data with "Export Records (CSV)"
6. Changes to This Policy
Material changes will be published on this page with an updated effective date.
