当前版本不含广告、第三方分析 SDK 或跨 App/网站追踪。
大多数数据保存在设备上
语言、位置选择、通知偏好和预报缓存保存在 App 容器与共享 Widget 容器中。
预报请求会离开设备
精确经纬度会随天气和空气质量请求发送给 Open-Meteo。
处理哪些数据
位置
你可以允许“使用 App 时”定位，也可以在设置中手动选择地点。App 会用经纬度计算当地日出、日落、极光和其他天空时刻，并将最近成功的位置保存在设备上。当 App 请求天气、空气质量或季节上下文时，经纬度会通过 HTTPS 直接发送给 Open-Meteo。若 iOS 允许后台刷新，最近保存的位置也可能用于后台预报请求。
偏好与本地缓存
App 会在设备上保存语言、手动地点、通知偏好、最后刷新时间、预报结果与展示状态。主 App 与 Widget 通过 iOS App Group 共享显示下一个天空时刻所需的最少数据。
系统权限与通知
定位、通知、Widget、Live Activity 和后台刷新都由 iOS 提供。当前版本的提醒与 Live Activity 在设备上安排；不会将 APNs device token 发送到 天空刚好 服务器。
如何使用数据
- 生成与当地天气、天文和季节相关的天空时刻与评分。
- 在 App、Widget、通知和 Live Activity 之间保持必要的状态。
- 记住你的语言、位置与提醒偏好，并降低重复网络请求。
天空刚好 不会出售你的个人数据，也不会把它用于广告定向。
系统服务与第三方数据提供者
- Open-Meteo：接收经纬度和所需预报字段，返回天气、空气质量与季节上下文。天空刚好 不控制数据提供者的服务器日志与保留规则。
- NOAA Space Weather Prediction Center：App 下载全球 OVATION 极光网格；该请求不携带设备精确位置。
- Apple 系统服务：Core Location、反向地理编码、通知、Widget、Live Activity 和设备备份受 Apple 的系统设置与隐私条款管理。
服务方、数据用途、更新频率与署名见数据来源。
保留、删除与你的选择
- 天空刚好 当前不运营用户账号或远程个人数据库。
- 本地偏好和缓存保留到被新数据替换、被 App 清理，或你删除 App。iOS 系统权限与备份由你的 Apple 设备设置管理。
- 你可在 iOS 设置中随时关闭定位、通知或后台 App 刷新，也可以改用手动地点。
- 删除 App 可清除 天空刚好 保存在 App 与共享 Widget 容器中的本地数据。
儿童与政策更新
天空刚好 面向一般用户，不会有意要求儿童提供姓名、联系方式或账号资料。
如果 App 未来启用远程推送、分析、账号或新的数据提供者，本政策将在相关功能上线前更新，并标明新的生效日期。

The short version
No account
The current version does not require registration or sign-in and has no user account database.
No ads or cross-app tracking
The current version contains no ads, third-party analytics SDK, or tracking across apps and websites.
Most data stays on your device
Language, location choices, notification preferences, and forecast caches stay in the app and shared Widget containers.
Forecast requests leave your device
Precise latitude and longitude are sent to Open-Meteo with weather and air-quality requests.
Data we handle
Location
You can allow location while using the app or select a place manually in Settings. SkyNote uses coordinates to calculate local sunrise, sunset, aurora, and other sky moments, and saves the latest successful location on your device. When the app requests weather, air quality, or seasonal context, coordinates are sent directly to Open-Meteo over HTTPS. If iOS grants background refresh time, the latest saved location may also be used for a background forecast request.
Preferences and local caches
The app stores language, manual locations, notification preferences, last-refresh times, forecast results, and display state on your device. The main app and Widget share the minimum data needed to show the next sky moment through an iOS App Group.
System permissions and notifications
Location, notifications, Widgets, Live Activities, and background refresh are provided by iOS. In the current version, reminders and Live Activities are scheduled on the device; an APNs device token is not sent to a SkyNote server.
How we use data
- Generate sky moments and scores based on local weather, astronomy, and seasonal context.
- Keep necessary state consistent across the app, Widget, notifications, and Live Activities.
- Remember your language, location, and reminder preferences while reducing duplicate network requests.
SkyNote does not sell your personal data or use it for targeted advertising.
System services and data providers
- Open-Meteo receives coordinates and requested forecast fields and returns weather, air-quality, and seasonal context. SkyNote does not control the provider's server logs or retention practices.
- NOAA Space Weather Prediction Center provides a global OVATION aurora grid. This request does not include the device's precise location.
- Apple system services provide Core Location, reverse geocoding, notifications, Widgets, Live Activities, and device backups under Apple's system settings and privacy terms.
See Data sources for providers, purposes, refresh intervals, and credits.
Retention, deletion, and your choices
- SkyNote currently operates no user account or remote personal-data database.
- Local preferences and caches remain until replaced, cleared by the app, or the app is deleted. iOS system permissions and backups are controlled through your Apple device settings.
- You can turn off location, notifications, or Background App Refresh in iOS Settings at any time, and you can use a manual place instead of device location.
- Deleting the app removes local data stored by SkyNote in its app and shared Widget containers.
Children and policy updates
SkyNote is a general-audience app and does not knowingly ask children for names, contact details, or account information.
If the app later enables remote push, analytics, accounts, or a new data provider, this policy will be updated before that feature goes live and will show a new effective date.
