scan3d 无需账号，不包含广告、内购、第三方分析 SDK 或开发者运营的云端扫描服务。应用不向开发者服务器上传扫描、相机图像或运动数据。

相机与深度：用于获取物体及场景形状、颜色、相机位置和贴图。前置 TrueDepth 用于几何采集，不用于身份识别或建立身份档案。原始扫描帧、深度和模型保存在本机应用目录，以支持计算和重新处理。

运动与设置：运动数据用于判断扫描稳定性；语言偏好保存在本机。应用计时用于采集节流和按键去重，不用于追踪。

分享与备份：只有你主动使用导出或系统共享时，所选文件才交给你选择的应用或服务，适用该服务的隐私政策。系统设备备份可能包含应用数据，取决于你的备份设置。

保留与删除：在模型库删除模型会移除对应模型和原始数据；卸载应用会删除本机应用数据。已导出的文件和系统备份需在相应位置另行管理。

支持与网站：你发送的支持邮件会包含你主动提供的内容，用于回复问题。不要提供不必要的私人扫描。访问此静态支持网站时，网站托管与网络服务可能记录常规访问日志；网页不使用广告或分析脚本。

如果未来数据处理方式变化，我们会更新此政策。你可以随时通过上述邮箱联系开发者。

scan3d requires no account and contains no ads, in-app purchases, third-party analytics SDKs or developer-operated cloud scanning service. The app does not upload scans, camera images or motion data to developer servers.

Camera and depth: Used to capture geometry, color, camera poses and textures. Front TrueDepth is used for geometry, not identity recognition or identity profiles. Original images, depth frames and models are stored in the app's on-device directory for processing and reprocessing.

Motion and preferences: Motion is used to assess scan stability. Language preferences stay on device. Timing is used for capture intervals and button debouncing, not tracking.

Sharing and backups: When you choose export or system sharing, selected files are handed to the app or service you select, under its privacy policy. Device backups may include app data depending on your backup settings.

Retention and deletion: Deleting a model removes its associated original scan data. Uninstalling the app removes local app data. Manage exported copies and device backups separately.

Support and website: Support email includes information you voluntarily provide, used to respond to your request. Avoid sending unnecessary private scans. Hosting and network services may keep normal access logs for this static website; it contains no advertising or analytics scripts.

We will update this policy if data handling changes. Contact the developer at the email above with questions.
