批量瘦图 隐私政策
更新日期：2026 年 10 月 25 日
「批量瘦图」（以下称「本 App」）是一款在你的 Mac 上本地运行的图片压缩工具。我们的原则很简单：你的图片不离开你的电脑。
我们不收集什么
- 不上传你的图片、文件名或文件夹结构。所有压缩、转格式、改名、去背景都在本机完成，不经过任何服务器。
- 不收集个人信息、账户信息、位置信息，不使用第三方统计或广告 SDK。
- 去背景功能使用 macOS 内置的主体识别（Vision 框架），同样在本机运行，不联网。
本 App 在你的电脑上保存什么
- 文件夹授权：你授权过的文件夹以系统「安全书签」的形式保存在 App 的沙盒容器里，只用于读写你让本 App 处理的图片。你可以随时在「设置 → 右键与授权」里移除。
- 操作记录：为了支持「撤销」，本 App 记录最近的处理操作（文件路径、时间、去向）。原图放进废纸篓或旁边的文件夹，清空废纸篓前都能找回。记录只保存在本机。
- 预设与设置：保存在本机的 App 沙盒容器中。
- 免费额度计数：免费版每天可处理 20 张，计数只在本机保存，不上传。
内购
「终生会员」通过 Apple 的 App 内购买完成。支付由 Apple 处理，本 App 不会接触你的支付信息。购买凭证由 Apple 的 StoreKit 在本机校验。
命令行与 AI Agent
可选的命令行工具 slim 与 MCP 服务器只在本机进程之间通信（CFMessagePort），不开放网络端口，不向外发送数据。你的 AI 工具（如 Claude Code）通过它请求本 App 处理文件；改动前会先给出计划，并需要你在 App 里授权文件夹。
反馈邮件
当你选择「发送反馈」时，本 App 会打开你的邮件客户端并预填版本号、系统版本和语言，便于我们定位问题。是否发送、发送什么，完全由你决定。我们只把这些信息用于回复你的反馈。
儿童
本 App 不面向 13 岁以下儿童收集任何信息（事实上也不收集任何人的信息）。
变更
政策有变化时会更新本页并修改日期。重大变化会在 App 更新说明中提示。

BatchSlim (“the app”) is an image compression tool that runs entirely on your Mac. Our principle is simple: your images never leave your computer.
What we do not collect
- We do not upload your images, file names or folder structure. Compression, conversion, renaming and background removal all happen on your machine and never touch a server.
- We do not collect personal information, account information or location, and we use no third-party analytics or advertising SDKs.
- Background removal uses the subject-segmentation feature built into macOS (the Vision framework), which also runs locally and offline.
What the app stores on your computer
- Folder authorizations: folders you authorize are stored as system security-scoped bookmarks inside the app's sandbox container and are used only to read and write the images you ask the app to process. You can remove them at any time in Settings → Finder & Access.
- Operation log: to support Undo, the app records recent operations (file paths, time, destination). Originals go to the Trash or a folder next door and can be restored until the Trash is emptied. The log stays on your machine.
- Presets and settings: stored in the app's sandbox container.
- Free-tier counter: the free version processes up to 20 images a day; the counter is stored locally only.
In-app purchase
The Lifetime purchase is made through Apple's In-App Purchase. Payment is handled by Apple; the app never sees your payment details. Receipts are verified locally by Apple's StoreKit.
Command line and AI agents
The optional slim command-line tool and MCP server communicate only between local processes (CFMessagePort). They open no network ports and send no data anywhere. Your AI tools (such as Claude Code) use them to ask the app to process files; every change is planned first and requires you to authorize the folder in the app.
Feedback email
When you choose “Send Feedback”, the app opens your mail client with the app version, macOS version and language pre-filled to help us diagnose issues. Whether and what you send is entirely up to you; we use that information only to reply to you.
Children
The app does not collect any information from children under 13 (in fact it collects no information from anyone).
Changes
If this policy changes, this page and its date will be updated. Significant changes will be mentioned in the app's release notes.
