DiskCleaner — a native macOS storage cleaner that keeps 10 GB free

Features

功能

Built to run unattended, so deletion is deliberately boring.

为无人值守而设计，所以删除逻辑刻意做得"无聊"。

🛟

Never run out of space

不再爆盘

Checks hourly and cleans only when free space drops below your target (10 GB by default) — then stops the instant it is met.

每小时检查一次，只有低于目标（默认 10 GB）才清理，达到目标立刻停止，绝不"过度清理"。

🍩

macOS-style storage view

macOS 风格储存空间

A colour stacked bar for Applications, Documents, Photos, Developer caches, System data… Hover a segment for the exact size.

彩色堆叠条展示应用程序、文稿、照片、开发者缓存、系统数据等分类；鼠标划入色块看精确大小。

📦

Per-app usage

每个应用的占用

Every app's bundle size plus its user data under ~/Library, sorted by size.

每个 App 的本体大小，加上它在 ~/Library 下的用户数据，按大小排序。

🧹

Per-app data manager

应用数据管理

Pick exactly what to delete. Caches and logs are preselected; chat records, databases and login state stay locked until you explicitly unlock them.

自己挑要删什么。缓存和日志默认勾选；聊天记录、数据库、登录状态**默认锁住**，必须手动解锁并二次确认。

🧭

Menu bar extra

菜单栏小图标

Free space next to the icon, a warning triangle when you drop below target, and a popover with disk, memory and quick actions.

图标旁显示可用空间，低于目标变 ⚠️，点击弹出磁盘、内存面板与快捷操作。

🔒

Private by design

纯本地

No telemetry, nothing uploaded. The only network request is the optional update check — turn it off and the app never opens a socket.

没有遥测、不上传任何数据。唯一的联网行为是可关闭的更新检查 —— 关掉后应用完全不碰网络。

How cleaning works

清理逻辑

Three tiers, from safest to most aggressive. Tier 3 never runs unless you ask for it.

三个等级，从最安全到最激进。第 3 级不主动开启就永远不会执行。

Tier	等级	What it removes	清理内容	Default
1	Caches & logs, Xcode DerivedData, crash reports, huge log files (truncated, not deleted)	缓存与日志、Xcode DerivedData、崩溃报告、超大日志（清空而非删除）	✅
2	npm / pnpm / pip / Homebrew / Go / Cargo / Gradle and other rebuildable developer caches	npm / pnpm / pip / Homebrew / Go / Cargo / Gradle 等可重建的开发缓存	✅
3	Xcode archives, iOS backups, Trash, old downloads — your personal data	Xcode 归档、iOS 备份、废纸篓、旧下载 —— 你的个人数据	report only	只报告

Safety: every target is on a whitelist and must live inside your home folder; ~/Documents, ~/Desktop, ~/.ssh, ~/Library/Keychains … are refused outright. Deletion is age-based, filenames are handled NUL-safely, every du has a hard timeout, and the whole run is logged to ~/Library/Logs/diskautoclean.log. 安全：所有清理目标都在白名单里且必须位于你的主目录内；~/Documents、~/Desktop、~/.ssh、~/Library/Keychains 等路径直接拒绝。按时间删除、文件名 NUL 安全处理、每个 du 都有硬超时，全过程记录到 ~/Library/Logs/diskautoclean.log。
