儿童与家庭共用设备的应用安装规则
适合儿童或多成员共用 iPhone / iPad 的下载、试用、权限与购买家庭规则。
Define who can approve purchases
Turn on Ask to Buy for child accounts and make sure the organizer receives requests on a device they actually use. An approval path that nobody sees is not a control.
先定义谁能批准购买
为儿童账号开启购买前询问，并确保组织者在常用设备上接收请求。没人看得到的审批路径不算控制。
Separate free downloads from paid risk
A free install can still lead to trials, subscriptions, or high-privilege permissions. Require a short review of monetization and privacy before approving any new app on a child device.
区分免费下载与付费风险
免费安装仍可能导致试用、订阅或高权限。批准儿童设备上的新应用前，要求快速检查变现模式和隐私。
Use Screen Time as a hard boundary
Limit in-app purchases, account changes, and deleting apps where appropriate. Combine restrictions with a passcode the child does not know. Soft reminders are not enough for aggressive game stores.
用屏幕使用时间作为硬边界
在合适场景限制 App 内购买、账户更改和删除应用，并配合孩子不知道的密码。对激进的游戏商店，软提醒不够。
Create an allowed-app shortlist
Households move faster when common education, messaging, and media apps are pre-approved, while unknown utilities and game clones require research. A shortlist reduces decision fatigue and accidental installs.
建立允许应用短名单
当常用教育、通讯和媒体应用被预批准，而未知工具与游戏克隆需要研究时，家庭决策会更快。短名单能降低决策疲劳和误装。
Review monthly, not only after incidents
Once a month, review installed apps, active subscriptions, permission lists, and Screen Time reports. Remove abandoned apps and cancel unused trials before they become recurring costs or privacy residue.
按月复查，而不是出事才查
每月复查已安装应用、有效订阅、权限列表和屏幕时间报告。在它们变成周期成本或隐私残留前，清理废弃应用并取消无用试用。
Teach a simple no-install rule
Agree that unknown free apps with aggressive ads, unclear developers, or unnecessary permissions are automatic no. Children and shared users need a rule they can apply without waiting for a long debate.
教一条简单的禁止安装规则
约定：广告激进、开发者不清或不必要权限过多的未知免费应用，默认禁止。儿童和共用用户需要一条不用长篇讨论就能执行的规则。
Publisher takeaway
Family device safety is a process: approval paths, hard restrictions, shortlists, and monthly review. Tools can help inspect risk, but household rules decide whether a free install becomes a lasting problem.
发布者总结
家庭设备安全是一套流程：审批路径、硬限制、短名单和每月复查。工具可帮助识别风险，但家庭规则决定一次免费安装会不会变成长期问题。
