呼呼 Huhu（以下简称"我们"）是一款帮助新手父母记录宝宝喂养、睡眠与成长的 iOS 应用。本隐私政策说明我们在您使用呼呼时收集哪些信息、如何使用这些信息，以及您拥有哪些权利。
Huhu ("we") is an iOS app that helps new parents track their baby's feeding, sleep, and growth. This policy explains what information we collect, how we use it, and what rights you have.
本政策适用于呼呼 App 的所有版本。使用 App 即表示您同意本政策。当政策发生重大变更时，我们会在 App 内通知您。
This policy applies to all versions of the Huhu app. By using the app you agree to this policy. We will notify you in the app when material changes are made.
所有宝宝相关数据均由父母主动记录。我们收集的信息分为四类：
All baby-related data is recorded by parents voluntarily. We collect four categories of information:
| 类别 Category | 数据项 Items | 用途 Purpose |
|---|---|---|
| 账号信息 | 登录邮箱（magic link / Apple 登录） | 账号识别与登录 |
| 宝宝档案 | 名字、生日、性别、头像 | 档案展示、月龄与生长曲线计算 |
| 使用记录 | 喂奶 / 睡眠 / 尿布等事件（含奶量、时间）、身高体重、里程碑照片、事件修改历史、家庭邀请码 | 时间轴、睡眠预测、日统计、WHO 生长曲线、多人同步 |
| 设备信息 | 推送 token、去标识化崩溃日志 | 提醒推送、修复崩溃 |
我们不做广告，不做用户画像，不出售任何个人信息。
We do not run ads, build user profiles, or sell personal information. Your data is used only to provide the app's features.
Account holders must be a parent or legal guardian. All baby data belongs to the guardian, who may export or delete it at any time. We do not knowingly collect information directly from children under 13.
We share data only with the infrastructure providers listed above, as necessary to operate the app. We never sell personal information and use no advertising SDKs.
Data is hosted in Supabase's US data centers, encrypted in transit (TLS) and at rest. Row-level security ensures only your family members can access your baby's data.
您可以随时查看、导出、更正或删除自己的数据。在 App「我的」→「设置」中可删除账号：删除账号将级联删除您的全部数据（含云端备份，按备份周期彻底清除）。
You may view, export, correct, or delete your data at any time. Deleting your account ("Me" → "Settings" → "Delete Account") permanently deletes all of your data, including cloud backups within the backup cycle.
华盛顿州用户在《My Health Data Act》下享有知情、删除与撤回同意的权利，可通过下方联系方式行使。
Washington State users have rights to know, delete, and withdraw consent under the My Health Data Act, exercisable via the contact below.
账号存续期间我们保留您的数据以提供服务。删除的事件保留 30 天软删除墓碑（用于同步冲突解决），之后彻底清除。删号后数据按备份周期彻底清除。
We retain your data while your account is active. Deleted events keep a 30-day tombstone for sync conflict resolution, then are purged. Account deletion removes all data within the backup cycle.
重大变更我们会通过 App 内通知和邮件告知您；继续使用 App 即视为接受更新后的政策。
We will notify you in the app and by email of material changes; continued use constitutes acceptance.
