隐私政策

生效日期:2026 年 10 月 11 日 · 适用于 iOS App「成长尺」(Growth Ruler)

一句话:照片和记录只存在你的手机上,不上传。我们只收集匿名的使用统计和崩溃报告,用来把 App 改好。

1. 我们收集什么

App 没有账号,没有广告,不追踪你。我们只通过两个服务收集下面这些:

不会收集:你的照片、名字、生日、体重、身高、健康记录、通讯录、精确位置。这些内容不离开你的手机。

这些数据不卖给任何人,不用于广告。

2. 你的照片和记录存在哪

你加进来的照片、体重、身高、健康记录和「第一次」,都保存在这台 iPhone 上 App 自己的文件夹里。我们看不到,也拿不到。删掉 App,这些数据就一起删掉了。如果你开了 iCloud 备份,它们会随整机备份一起由 Apple 保存,这由你的 iCloud 设置决定。

3. App 用到的权限

4. 抠图

把主角从照片里抠出来,用的是 iPhone 自带的识别功能,在手机上完成。照片不会上传。

5. 购买

Pro 通过 App Store 购买,由 Apple 处理付款。我们拿不到你的付款信息,只知道「买了哪一种、是否有效」。

6. 生长参考线

记录孩子时显示的参考线来自世界卫生组织(WHO)公开的儿童生长标准,数据装在 App 里,在手机上计算。它只供参考,不是医疗诊断。

7. 儿童

App 给家长和宠物主人使用,不面向儿童,也不收集儿童的任何信息。

8. 分享

只有你自己点「分享」时,卡片或视频才会交给你选的 App(例如微信、相册)。

9. 政策变更

如果以后收集的内容有变化,我们会先更新本页和 App Store 上的隐私说明。

10. 联系

Privacy Policy

Effective 11 October 2026 · iOS app “Growth Ruler” (成长尺)

Your photos and records never leave your iPhone. The app has no account and no ads, and does not track you. We collect only anonymous usage statistics through PostHog (which features are used, e.g. “added 5 photos”, with a random anonymous ID; country is inferred from the IP address, which is not stored) crash/performance diagnostics through Sentry (device model, OS version, where the error happened; no screenshots), and, if you buy Pro, purchase status through RevenueCat (which plan, when it expires, tied to the same anonymous ID; no name or payment details). We never collect your photos, names, birthdays, weights, heights or health records. Data is not sold and not used for advertising.

Photos, weights, heights, health records and milestones are stored only on your iPhone, inside the app’s own folder. Deleting the app deletes them. If iCloud Backup is on, Apple keeps them as part of your device backup.

Permissions. Camera: only when you take a monthly photo. Photos: the app receives only the photos you pick in the system picker, and can add (not read) images when you save a card. Notifications: local reminders on the monthly day and when a reminder is due.

Subject cut-outs run on the device with built-in iOS features; photos are never uploaded. Purchases are handled by Apple; we never see payment details. Growth reference lines come from the public WHO growth standards, are bundled in the app, and are for reference only, not a diagnosis.

The app is for parents and pet owners; it is not directed to children and collects no information from them. Contact: ianloe666@gmail.com
