设备本地处理
DocSignKit 无需账号。照片去背景、素材提取、文档转换、编辑和导出均在设备本地完成。应用不向我们的服务器上传照片、签名、印章、文档或编辑记录，也不包含广告、行为统计或追踪服务。
本地保存与文件访问
你选择导入的文档副本、透明素材和编辑状态保存在应用本地目录，用于之后继续编辑。导出文件保存在你通过系统文件面板选择的位置。应用只访问你选择的文件及自己的本地存储空间。
数据控制
你可以在素材库和文档列表删除记录。删除素材库条目不会删除已用于文档的素材副本；删除文档会删除该项目的本地副本。请在卸载或清除应用数据前导出重要资料。应用未提供应用级密码或额外文件加密。

Local processing and storage
DocSignKit requires no account. Photo extraction, document conversion, editing and PDF export run on your device. The app does not upload your photos, signatures, seals, documents or editing records to our servers. It includes no advertising, analytics or tracking services.
Imported copies, reusable assets and editing state are stored in the app's local directory. Exported files are saved to a location you choose. You can delete projects and library items in the app. Existing projects retain their own copies of assets. Export important files before uninstalling or clearing app data. No additional app-level password or file encryption is provided.
