iPhone 和 iPad 家庭共享购买安全
适合家庭用户的购买安全检查，覆盖共用设备、付款方式、订阅和 App Store 购买权限。
Review Ask to Buy
For children in a Family Sharing group, Ask to Buy can reduce accidental paid downloads and in-app purchases. Confirm that the organizer receives approval requests on a device they actually use.
检查购买前询问
对于家庭共享中的儿童账号，购买前询问可以减少误下载付费应用和误买内购。需要确认组织者能在常用设备上收到审批请求。
Separate subscriptions from one-time purchases
A shared app download does not always mean every subscription benefit is shared. Before paying, check whether the app supports Family Sharing for subscriptions or only for the app download itself.
区分订阅和一次性购买
共享应用下载并不代表所有订阅权益都会共享。付款前要确认该应用支持共享订阅，还是只共享应用本体下载。
Check shared devices
On shared iPads or older iPhones, make sure the signed-in Apple ID is correct before purchasing. A purchase made under the wrong account may be difficult to move later.
检查共用设备
在共用 iPad 或旧 iPhone 上购买前，先确认登录的是正确的 Apple ID。买到错误账号下的内容，后续通常很难迁移。
Talk about trial reminders
If a family member starts a free trial, agree on who will review it before renewal. A simple calendar reminder can prevent surprise charges across the family payment method.
约定试用提醒
如果家庭成员开启免费试用，最好提前约定谁来检查是否续订。一个日历提醒就能减少家庭付款方式上的意外扣费。
