<h2>关于回头看看</h2>
<p>「回头看看」把你的微信读书划线,变成打开干扰 App 前的那一眼。选择最多 3 个容易让你分心的 App,它们会默认锁定;每次打开,先看到一条你自己划过的书摘,再决定是继续阅读一条,还是解锁 10 分钟。</p>
</div>

<div class="section">
<h2>系统要求</h2>
<ul>
    <li>iPhone,iOS 16.0 或更高版本</li>
    <li>设备已设置锁屏密码(开启屏幕使用时间权限的系统要求)</li>
</ul>
</div>

<h2>常见问题</h2>

<h3>Q: 微信读书 API Key 是什么?</h3>
<p>API Key 是微信读书官方提供的个人访问凭证(以 wrk- 开头)。粘贴到 App 中后,「回头看看」只用它同步你自己账号下的划线和书籍封面,Key 仅保存在你的设备本地。</p>

<h3>Q: 为什么需要屏幕使用时间权限?</h3>
<p>App 使用 Apple 官方的 Family Controls / Screen Time API 来锁定你选中的 App。锁定与解锁全部由系统执行,App 无法读取你的使用记录。</p>

<h3>Q: 「解锁 10 分钟」怎么计时?</h3>
<p>点击解锁后开始 10 分钟倒计时(自然时间),到期后自动重新锁定,无需手动操作。</p>

<h3>Q: 我的数据安全吗?</h3>
<p>所有数据(API Key、划线内容、封面图)均存储在你的设备本地,App 没有自己的服务器,不收集、不上传任何数据。详见<a href="privacy-policy.html">隐私政策</a>。</p>

<h3>Q: 想暂停使用怎么办?</h3>
<p>在选择干扰 App 的页面取消全部勾选即可解除所有锁定;或在设置页使用「重置」彻底清空屏幕时间授权与锁定状态。</p>

<h2>FAQ</h2>

<h3>Q: What is the WeChat Reading API Key?</h3>
<p>It is a personal access credential (starting with wrk-) provided by WeChat Reading. The app only uses it to sync your own highlights and book covers, and it is stored locally on your device.</p>

<h3>Q: Why does the app need Screen Time permission?</h3>
<p>The app uses Apple's official Family Controls / Screen Time API to shield the apps you choose. Shielding is enforced by the system; the app cannot read your usage history.</p>

<h3>Q: Is my data safe?</h3>
<p>Everything (API key, highlights, covers) is stored locally on your device. The app has no backend server and collects nothing. See our <a href="privacy-policy.html">Privacy Policy</a>.</p>
