Privacy Policy
Pumpful is built to be private by default. Last updated: August 25, 2026.
This policy describes how Pumpful (“we”, “the app”) handles your information. The short version: your data stays on your devices. The only thing that ever leaves your device is the anonymous usage statistics described below. We don’t show ads, and we don’t track you.
What we collect
Almost nothing. The only data the app handles is the pumping and feeding information you enter:
- Session data you type in — volume, side, duration, notes, and timestamps.
- This data is stored locally on your device using SwiftData (Apple’s on-device database).
If you turn on iCloud sync, your session data syncs across your own devices through Apple CloudKit, in a private database that only you can access. We cannot read it.
Anonymous usage analytics
To understand which screens and features are actually useful, the app sends a small amount of anonymous usage analytics to our own backend: which screens you open and which buttons you tap, along with a random device identifier generated by the app. This data is:
- Never your content — no volumes, notes, durations, or session timestamps are collected or sent.
- Not linked to you — the identifier is a random ID stored only on your device; we don’t know who you are.
- Used only to improve Pumpful — never sold, shared, or used for advertising, and never used to track you across apps or websites.
The app also receives aggregated crash and performance diagnostics from Apple (MetricKit) so we can fix issues faster. These reports contain no personal data.
Purchases
Pumpful Pro subscriptions and any purchases are processed entirely by Apple through StoreKit. We never see your payment method, and Apple does not share your personal billing details with us. The app only learns whether a Pro subscription is active. At launch, purchase verification happens on your device — we do not transmit your purchase data to any server.
What we don’t do
- No advertising or ad networks.
- No third-party analytics, advertising, or crash-reporting SDKs — the anonymous statistics described above go to our own backend and contain none of your content.
- No tracking across other apps or websites.
- No account or sign-in is required to use the app.
- No selling or sharing of your data — ever.
Notifications
Pumpful uses local notifications only — to remind you between pumps. These stay on your device. We never send you marketing messages.
Your choices
- Delete your data at any time from within the app, or by removing the app.
- Manage iCloud sync in your device’s iCloud settings.
- Manage notifications in your device’s Settings.
- Manage or cancel subscriptions in your Apple ID settings.
Children’s privacy
Pumpful is a tool for parents and caregivers. We don’t knowingly collect data from children, and the app doesn’t ask for a child’s personal information.
Changes to this policy
If we change how the app handles data, we’ll update this page and the “last updated” date. Any feature that adds data collection will be clearly disclosed here.

隐私政策
Pumpful 天生注重隐私。最后更新：2026 年 8 月 25 日。
本政策说明 Pumpful（“我们”、“本应用”）如何处理你的信息。简单来说：你的数据只留在你的设备上，唯一会离开设备的是下述匿名使用统计。我们不投放广告，也不追踪你。
我们收集什么
几乎没有。应用处理的唯一数据，是你输入的吸奶 / 喂养信息：
- 你输入的会话数据——奶量、左右侧、时长、备注与时间。
- 这些数据通过 SwiftData（Apple 的设备端数据库）存储在你的设备本地。
如果你开启 iCloud 同步，会话数据会通过 Apple CloudKit 在你自己的设备间同步，存于只有你能访问的私有数据库。我们无法读取。
匿名使用统计
为了了解哪些页面和功能真正有用，应用会向我们自己的后端发送少量匿名使用统计：你打开了哪些页面、点击了哪些按钮，以及一个由应用随机生成的设备标识符。这些数据：
- 绝不包含你的内容——不收集、不发送奶量、备注、时长或会话时间。
- 不与你本人关联——标识符是只存储在你设备上的随机 ID，我们不知道你是谁。
- 仅用于改进 Pumpful——绝不出售、共享或用于广告，也绝不用于跨应用或网站追踪你。
应用还会通过 Apple（MetricKit）接收汇总的崩溃与性能诊断，以便更快修复问题。这些报告不包含任何个人数据。
购买
Pumpful Pro 订阅及任何购买均完全由 Apple 通过 StoreKit 处理。我们看不到你的支付方式，Apple 也不会把你的账单信息分享给我们。应用只会知道 Pro 订阅是否处于有效状态。上线时，购买校验在设备本地完成——我们不会把你的购买数据发送到任何服务器。
我们不会做的事
- 无广告、无广告网络。
- 无第三方分析、广告或崩溃上报 SDK——上述匿名统计发送至我们自己的后端，且不包含任何内容数据。
- 不跨应用或网站追踪你。
- 使用应用无需注册账号或登录。
- 绝不出售或共享你的数据。
通知
Pumpful 仅使用本地通知——在两次吸奶之间提醒你。通知只留在你的设备上，我们绝不会向你发送营销信息。
你的选择
- 可随时在应用内删除数据，或删除应用。
- 在设备的 iCloud 设置中管理同步。
- 在设备「设置」中管理通知。
- 在 Apple ID 设置中管理或取消订阅。
儿童隐私
Pumpful 是面向父母与照护者的工具。我们不会有意收集儿童数据，应用也不会索取儿童的个人信息。
政策变更
若我们更改应用处理数据的方式，会更新本页面及“最后更新”日期。未来任何新增数据收集的功能都会在本页清晰告知。
