Companion app for CZero, a root cache-cleaning module for Android.

CZero has no resident service — an extremely lightweight native process triggers every task on schedule, and config changes take effect immediately. Day-to-day operation goes through CZeroX, the module's only graphical frontend (Jetpack Compose, Miuix style), which reads and writes the module's configuration directly — no WebUI.

• Cache cleaning — dedicated cleaners for WeChat, QQ and Douyin, plus everything else, with foreground- and game-aware checks so nothing running is touched.
• Background suppression — periodically ends target apps' background subprocesses to free memory; the foreground app is never touched.
• Fine-grained suppression (Android 12+) — the gentle counterpart to the above: suspends an app without killing it, so its in-memory state survives and switching back is instant. Managed per app in CZeroX.
• F2FS garbage collection & fstrim — reclaims fragmented free space and keeps storage write performance healthy, only running when the device is genuinely idle.
• Empty-folder cleanup — sweeps leftover empty directories on a schedule.
• Custom rules & rule sources — declare your own cleaning paths and whitelist, or subscribe to community rule sources that auto-update daily.
• Recycle bin — cleaned files are moved, not deleted, and stay recoverable for 7 days by default.
• Storage panel — device (UFS/eMMC) lifespan, live read/write throughput, and a benchmark, all read-only aside from the benchmark's own temporary test file.
• Stats & notifications — 90-day cleaning history and per-run progress/results, including Dynamic Island support.

• Android 9+ (API 28), arm64-v8a
• Root via Magisk, KernelSU, or APatch
• LSPosed, to enable CZeroX
• F2FS /data partition (only for the GC feature; everything else works regardless)

CZero 是一款 Android Root 端缓存清理模块，没有常驻服务，所有任务由一个极轻量的原生进程按计划触发，配置修改即时生效。日常操作通过 CZeroX 完成——它是模块唯一的图形化配置前端（Jetpack Compose，Miuix 风格），直接读写模块配置，不依赖 WebUI。

• 缓存清理 —— 针对微信、QQ、抖音的独立清理器，以及其他应用的通用清理，清理前会检测前台与游戏状态，正在使用的应用不受影响。
• 后台压制 —— 定期结束目标应用在后台的子进程以释放内存，前台应用绝不触碰。
• 精细化压制（Android 12+） —— 后台压制的温和版本：挂起应用而不结束进程，内存状态完整保留，切回瞬间恢复。压制名单在 CZeroX 里按应用管理。
• F2FS 垃圾回收与 fstrim —— 整理碎片化存储空间、维持长期写入性能，仅在设备真正空闲时执行。
• 空文件夹清理 —— 按计划清扫残留的空目录。
• 自定义规则与规则源 —— 自行声明清理路径与白名单，也可订阅社区规则源，每天自动更新。
• 回收站 —— 清理是移动而非删除，默认保留 7 天可完整恢复。
• 存储面板 —— 器件（UFS/eMMC）寿命、实时读写速率与性能测试，除测试自身产生的临时文件外均为只读读取。
• 统计与通知 —— 90 天清理历史，执行进度与结果通知，支持超级岛。

• Android 9+（API 28），arm64-v8a
• Root 方案：Magisk、KernelSU 或 APatch
• 已安装 LSPosed，用于启用 CZeroX
• F2FS /data 分区（仅 GC 功能需要，其余功能不受影响）
