App Store 免费试用陷阱清单
帮助你避开免费试用后意外续费的警示信号、时间陷阱和清理步骤。
Record the end date before you start
If you cannot immediately write down the trial end date, renewal price, and cancellation path, do not start the trial. Memory is a weak billing system. A calendar reminder one day early is the minimum control.
开始前先记录结束日期
如果你不能立刻写下试用结束日期、续费价格和取消路径，就不要开始试用。记忆是很弱的账单系统。至少提前一天设置日历提醒。
Read the offer sheet, not the marketing screen
Marketing copy emphasizes free. The offer sheet shows what happens after free. Check whether the plan is weekly, monthly, or annual, and whether introductory pricing jumps sharply later.
看报价页，而不是营销页
营销文案强调免费，报价页才写明免费之后会发生什么。检查方案是周付、月付还是年付，以及首期优惠之后是否大幅上涨。
Watch for short high-pressure trials
Three-day trials with weekly renewals are easier to miss and more expensive over a month. If the product is not critical, skip short trials that convert into aggressive billing periods.
警惕短周期高压试用
三天试用配周续费更容易错过，按月累计也更贵。如果产品不是刚需，跳过那些会转成激进计费周期的短试用。
Cancel first, evaluate second
If you are still unsure near the end of the trial, cancel and keep using access until expiry. You can resubscribe later if the product proves valuable. The reverse order creates refund work.
先取消，再评估
试用临近结束仍不确定时，先取消，再继续用到到期。产品证明有价值后再重新订阅。反过来做只会制造退款工作。
Protect shared payment methods
On family devices, enable Ask to Buy and purchase restrictions. One free trial on a shared iPad can become a recurring household charge. Review who can approve purchases and which card is attached.
保护共享付款方式
家庭设备上开启购买前询问和购买限制。共用 iPad 上的一次免费试用，可能变成家庭的周期扣费。复查谁能批准购买，以及绑定了哪张卡。
Cleanup after the trial ends
Confirm cancellation state, remove unused apps if they create clutter, revoke unnecessary permissions, and check purchase history for unexpected renewals. Keep screenshots if you may need support later.
试用结束后清理
确认取消状态，清理造成杂乱的无用应用，撤销不必要权限，并检查购买记录是否有意外续费。如果后续可能需要支持，保留截图。
Publisher takeaway
Free trials are useful only with active management. The trap is not free access; the trap is silent conversion. Use reminders, early cancellation, and family controls before you trust any trial on a primary payment method.
发布者总结
免费试用只有在主动管理下才有用。陷阱不是免费使用，而是静默转正。在把试用交给主力付款方式前，先用提醒、提前取消和家庭控制兜底。
