Linework 是一款离线二维 CAD 编辑器。本政策说明当前测试版本如何处理文件和本地数据。

1. 我们不收集的数据

当前版本不要求注册或登录，不设账户系统，不包含广告、分析、崩溃上报、第三方追踪 SDK 或云端同步。App 不会将图纸、坐标、文字、设备标识符或使用记录发送到 Linework 的服务器，因为当前版本没有 Linework 服务器或网络服务。

2. 设备上的文件和本地数据

当你从 iOS“文件”选择 DWG 或 DXF 时，Linework 会读取所选文件，并将工作副本写入 App 自己的本地应用支持目录，以便提供最近打开列表和离线重开。编辑后的 DWG、DXF、PDF 或 PNG 仅在你主动通过系统导出面板选择位置后写入该位置。源文件不会被 Linework 原地覆盖。

最近打开列表仅保存文件名、格式和工作副本位置，并保存在设备本地。图纸内容、导出文件及最近列表均不会上传。

本网站在浏览器本地保存语言偏好，且未嵌入广告或分析脚本。Cloudflare 为网站提供托管和安全防护，可能按其政策处理常规访问数据。如果你主动发送支持邮件，我们会使用来信内容和地址答复。请先移除图纸中的敏感信息。

3. 保留与删除

你可以在“文件”中删除你主动导出的副本。移除 Linework 或清除其 App 数据会删除 App 沙盒中的工作副本和最近列表。原始图纸仍由你在“文件”或其他存储提供商中管理，不受移除 Linework 的影响。

4. 权限

Linework 通过 iOS 系统文件选择器访问你明确选取的文件。它不会扫描你的全部文件，也不请求通讯录、位置、相机、麦克风或照片图库权限。

5. 面向儿童

Linework 不以儿童为对象，也不会在当前版本中有意收集任何个人信息。

6. 后续版本

若未来加入账户、同步、分析、支付或支持服务，Linework 会在上线前更新本政策和 App Store 的隐私披露。届时只有符合更新后政策的功能才会开始处理相应数据。

7. 联系与生效

Linework 由 C-ERA INTERNATIONAL TECHNOLOGY LIMITED 运营。隐私问题可发送至 support@cera.hk。本政策适用于当前预发布测试版本，并将在公开发布前与 App Store 产品页信息一并复核。

Linework is an offline 2D CAD editor. This policy explains how the current test build handles drawings and local data.

1. Data we do not collect

The current build has no registration, sign-in, account system, advertising, analytics, crash reporting, third-party tracking SDK, or cloud sync. It does not send drawings, coordinates, text, device identifiers, or usage records to a Linework server. The current build has no Linework server or network service.

2. Files and local data on your device

When you choose a DWG or DXF in the iOS Files picker, Linework reads that selected file and writes a working copy to its own local Application Support directory so recent drawings can reopen offline. Edited DWG, DXF, PDF, and PNG files are written only when you choose a destination in the system export panel. Linework does not overwrite the source file in place.

The recent list stores only the file name, format, and local working-copy location on the device. Drawing contents, exports, and the recent list are not uploaded.

This website stores your language preference in your browser and includes no advertising or analytics scripts. Cloudflare provides hosting and security and may process routine visit data under its own policy. If you email support, we use your address and message to respond. Remove sensitive drawing information before sharing it.

3. Retention and deletion

You can delete copies you exported in Files. Removing Linework or clearing its app data removes its sandboxed working copies and recent list. The original drawing remains managed by you in Files or another storage provider.

4. Permissions

Linework accesses only files you deliberately select through the iOS Files picker. It does not scan your files and does not request contacts, location, camera, microphone, or photo-library access.

5. Children

Linework is not directed to children and the current build does not knowingly collect personal information.

6. Future versions

If accounts, sync, analytics, payments, or support services are added later, this policy and App Store privacy disclosures will be updated before those features are released.

7. Contact and effective scope

Linework is operated by C-ERA INTERNATIONAL TECHNOLOGY LIMITED. For privacy questions, contact support@cera.hk. This policy applies to the current pre-release test build and will be reviewed alongside App Store product-page information before public release.
