中文
欢迎使用「Yaya: Sow a Habit」（中文名：芽芽 · 绿植田野，下称「本应用」）。本政策说明我们如何收集、使用与保护与您相关的信息。使用本应用即表示您了解并同意本政策。
1. 我们是谁
本应用是一款在设备上运行的习惯养成与绿植养成工具：您可以把日常习惯当作种子种进田野，植物会随打卡生长。田野画面会尝试与您所在地的季节、天气、月相、星空及空间站过境保持一致。我们没有自有账号系统，也没有自有云端用户数据库。
2. 我们收集哪些信息
- 位置信息（可选）：仅在您点击定位并授予系统权限后使用。用于：把坐标解析为地名、向公开气象接口请求当地天气与空气质量、计算当地日出日落、判断夜空星座可见性、估算国际空间站（ISS）与天宫空间站（CSS）相对您所在地的过境。经纬度与地名保存在本机。您可以不开启定位，本应用仍可使用；届时将使用默认或手动环境，而不请求当地实时天气与过境。
- 习惯与养成数据：习惯名称、打卡记录、植物成长进度、设置（含通知与音效开关）等，仅保存在设备本地（WebView 的本地存储）。
- 提醒内容：若您开启习惯提醒，习惯名称与提醒时刻会交给系统闹钟/通知通道，以便在约定时间提醒您。这些信息不上传到我们的服务器。
- 我们不收集：姓名、电话、电子邮箱、通讯录、精确身份证件；不要求注册账号；不嵌入广告 SDK、分析 SDK 或崩溃收集 SDK。
3. 我们如何使用信息
- 在本机提供习惯打卡、植物生长、田野场景与提醒；
- 在您授权定位后，向公开接口请求当地天气与地名，并在本地计算天象与空间站轨迹；
- 不将您的习惯内容或位置用于广告、画像或出售。
4. 信息共享与第三方
我们不会出售您的个人信息。为实现可选的「当地实时环境」功能，本应用可能直接从您的设备向下列第三方公开服务发起网络请求（仅在您授权定位并启用相关功能时）：
- Open-Meteo：根据经纬度返回天气、日出日落与空气质量；
- BigDataCloud 逆地理编码：把经纬度解析为可读地名。
上述请求会向相应服务提供您的经纬度。其处理方式以其各自隐私政策为准。国际空间站与天宫的轨道展示基于本机测算，不为此向我们或第三方上传您的身份信息。
5. 权限说明
- 网络：下载天气、地名等公开数据；无网络时本地习惯与植物功能仍可使用。
- 定位（精确/大致）：仅用于上一节所述当地环境与过境，需您主动开启。
- 通知：用于习惯打卡提醒，可在应用内或系统设置中关闭。
- 开机启动：用于设备重启后恢复您已开启的本地提醒，不会因此上传数据。
6. 数据保存与安全
习惯、植物与设置保存在您的设备上。卸载本应用通常会清除 WebView 本地存储。若系统开启了 Android 备份，部分数据可能随系统备份被恢复。我们采取合理措施保护应用安全，但任何电子设备都无法保证绝对安全。
7. 儿童隐私
本应用不以 13 岁以下儿童为主要对象，也不故意收集儿童的个人信息。若您认为发生了误收集，请通过下方方式联系我们。
8. 您的选择
- 拒绝或关闭定位权限；
- 在「我的」中关闭提醒通知、环境音效或背景音乐；
- 卸载应用以停止使用并（通常）清除本机存档。
9. 政策更新
我们可能不时更新本政策，并在本页修订「最近更新」日期。重大变更时，我们将尽量通过应用商店说明或其他合理方式提示。
10. 联系我们
如对本政策有疑问，请通过本仓库 GitHub Issues 联系我们，或在 Google Play 应用页留下反馈。
English
This Privacy Policy describes how Yaya: Sow a Habit (Chinese name: 芽芽 · 绿植田野; package name com.sprout.field; the “App”) collects, uses, and protects information. By using the App, you agree to this Policy.
1. Who we are
The App is an on-device habit tracker and plant-growing companion: habits are sown like seeds, and a living field follows local season, weather, moon phase, stars, and space-station passes when you allow location. We operate no user accounts and no cloud user database of our own.
2. Information we collect
- Location (optional): used only after you tap locate and grant system permission — to reverse-geocode a place name, request public weather and air quality, compute local sunrise/sunset, estimate constellation visibility, and estimate ISS and China Space Station (Tiangong) passes relative to you. Coordinates and place name are stored on device. The App works without location, using default or manual environment instead of live local weather and passes.
- Habits and growth data: habit names, check-ins, plant progress, and settings (including notification and sound toggles) are stored only in on-device WebView storage.
- Reminder payload: if reminders are on, habit names and times are handed to the Android alarm/notification system locally. They are not uploaded to our servers.
- We do not collect your name, phone number, email, contacts, or government IDs by default. We do not require sign-in. We do not embed advertising, analytics, or crash-reporting SDKs.
3. How we use information
- To provide habit check-ins, plant growth, the field scene, and local reminders;
- If you grant location, to fetch public weather/place data and to compute sky and station geometry on device;
- Not to sell data, build advertising profiles, or run third-party ads.
4. Sharing and third parties
We do not sell personal information. For optional live-local environment features, the App may request the following public third-party services directly from your device (when location is authorized):
- Open-Meteo for weather, sunrise/sunset, and air quality;
- BigDataCloud reverse geocoding for a readable place name.
Those requests include your coordinates. Their processing is governed by their own policies. ISS and Tiangong tracks are computed on device.
5. Permissions
- Internet: to fetch public weather and place data. Habits and plants work offline.
- Location (fine/coarse): only for the live-local features above, and only if you opt in.
- Notifications: habit reminders; can be turned off in the App or system settings.
- Boot completed: to restore local reminders after reboot; no data is uploaded for this.
6. Retention and security
Habit, plant, and settings data stay on your device. Uninstalling the App typically clears WebView storage. If Android Backup is enabled, some data may be restored with a system backup. We take reasonable care, but no electronic system is perfectly secure.
7. Children
The App is not directed at children under 13, and we do not knowingly collect their personal information. Contact us if you believe we have done so in error.
8. Your choices
- Deny or revoke location;
- Turn off reminders, ambient sound, or background music in Me;
- Uninstall the App to stop use and (typically) erase local saves.
9. Updates
We may update this Policy and will revise the “Last updated” date on this page. For material changes we will try to note them in the store listing or another reasonable way.
