安装说明Installation Guide

在手机浏览器中打开 www.paysound.app，点击「下载 APK」按钮，等待下载完成。Open www.paysound.app in your phone's browser and tap the "Download APK" button. Wait for the download to complete.

PaySound 未上架 Google Play，安装包直接从官网下载。Google Play Protect 是 Android 的安全扫描机制，它只信任经过 Google 审核的应用，对于来自 Play 商店以外的 APK，默认会弹出警告甚至阻止安装。PaySound is distributed directly from its own website rather than through Google Play. Google Play Protect is Android's built-in security scanner — it only trusts apps that have passed Google's review process, so it may warn about or block any APK installed from outside the Play Store.

PaySound 使用了无障碍权限来读取银行通知并播报金额。无障碍权限属于 Android 最高敏感级别的权限之一，Play Protect 对使用此权限的非 Play 商店 App 审查极为严格，即使没有任何恶意行为也可能触发警告。PaySound 绝无恶意，绝对安全。如果担心，建议用一台不用的旧安卓手机安装，并把此手机作为收款专用。暂停 Play Protect 后即可顺利完成安装。PaySound uses the Accessibility permission to read bank notifications and announce payment amounts. Accessibility is one of Android's most sensitive permissions — Play Protect scrutinises any app that uses it when installed outside the Play Store, and may block installation even if the app is completely safe. PaySound is completely safe and contains no malicious code. If you are still concerned, we recommend installing it on an old spare Android phone and dedicating that device solely for receiving payments. Pausing Play Protect allows the installation to proceed.

打开手机的「下载」文件夹，点击刚才下载的 PaySound APK 文件。Open your phone's "Downloads" folder and tap the PaySound APK file you just downloaded.

系统提示「安装未知来源应用」时，点击允许，然后点击安装，等待完成。When prompted to "Install unknown apps", tap Allow, then tap Install and wait for it to complete.

在手机桌面找到 PaySound 的图标 并点击。 Find the PaySound icon on your home screen and tap it.
