隐私政策

最后更新:2026 年 8 月 14 日

InkDown 不收集你的任何个人信息。没有账号,没有服务器,没有分析工具。你的笔记和笔迹只存在于你自己的设备上。

我们收集什么

没有。InkDown 不含任何分析、追踪、崩溃上报或广告 SDK,也没有配套的后端服务。我们无法看到你是谁、你写了什么、你什么时候用它。

你的笔记存在哪

笔记文件保存在你通过系统文件浏览器选定的位置——设备本地或你自己的云盘(如 iCloud Drive)。这个选择完全由你和 Apple 的系统组件完成,InkDown 不会把文件复制到别处,我们也无从访问。

手写与数学识别

InkMath 手写数学识别引擎完全在设备上离线运行。笔迹数据不会离开你的设备,不会被上传用于模型训练。你在应用内创建的自定义符号模板同样只保存在本地。

网络连接

InkDown 本身不向我们的任何服务器发送数据。只有一种情况会产生对外网络请求:

诊断日志

InkDown 会在应用自己的沙盒容器内写入识别引擎的诊断日志,用于排查问题。该日志不会被自动发送到任何地方,随应用卸载一并删除。仅当你主动导出并发给我们时,我们才会看到它。

第三方组件

应用内置了开源数学排版库 SwiftMath,用于公式渲染。它在设备上本地运行,不进行任何网络通信,也不收集数据。

儿童

由于 InkDown 不收集任何个人信息,它同样不会收集儿童的个人信息。

政策变更

若本政策发生变更,我们会更新本页顶部的日期。涉及数据处理方式的实质性变更,会在应用内一并说明。

Privacy Policy

Last updated: 14 August 2026

InkDown collects nothing about you. No accounts, no servers, no analytics. Your notes and handwriting stay on your own device.

What we collect

Nothing. InkDown contains no analytics, tracking, crash-reporting, or advertising SDKs, and there is no backend service behind it. We cannot see who you are, what you write, or when you use the app.

Where your notes live

Note files are stored in the location you choose through the system document browser — on your device or in your own cloud storage such as iCloud Drive. That choice is handled entirely by you and Apple's system components. InkDown does not copy your files anywhere else, and we have no access to them.

Handwriting and math recognition

The InkMath handwriting recognition engine runs entirely on-device and offline. Ink data never leaves your device and is never uploaded for model training. Custom symbol templates you create in the app are likewise stored only locally.

Network connections

InkDown never sends data to any server of ours. Exactly one situation produces outbound network traffic:

Diagnostic logs

InkDown writes recognition-engine diagnostic logs inside the app's own sandbox container to help troubleshoot problems. These logs are never transmitted anywhere automatically and are deleted when the app is removed. We see them only if you choose to export and send them to us.

Third-party components

The app bundles SwiftMath, an open-source math typesetting library used for formula rendering. It runs locally, performs no network communication, and collects no data.

Children

Because InkDown collects no personal information at all, it likewise collects none from children.

Changes to this policy

If this policy changes, we will update the date at the top of this page. Material changes to how data is handled will also be explained in the app.
