数隐通的全部功能（扫描、识别、脱敏、还原、留痕）均在本机完成。 应用不包含任何联网代码、遥测上报、统计埋点或账号体系，也不使用 Cookie。
| 数据 | 位置 | 说明 |
|---|---|---|
| 留痕数据库 | 本机数据目录下的 data/privamask.db（SQLite） | 处理前后文件 hash、脱敏前后文件名、原路径与输出路径（位置）、替换映射 |
| 脱敏结果 | 任务输出目录 data/output/<任务时间戳>/（内部保持原目录相对结构） | 脱敏后的文件副本；源文件只读不改 |
| 还原产物 | data/output/restore/<任务时间戳>/ | 还原得到的文件 |
| 规则与设置 | 同上本机数据库 | 脱敏规则、留痕开关等界面配置 |
这些数据只存在于你的电脑，不向任何服务器传输。
导出的映射规则 xlsx 与留痕数据库中包含原文（脱敏前真实值）的映射—— 谁持有它们，谁就能把脱敏数据还原为原文。请自行妥善保管，并按需清理； 应用内在还原界面提供按任务清理留痕的入口。
脱敏过程不修改、不移动、不删除你的源文件；所有结果都写入输出目录中的新文件。
卸载应用不会自动删除数据目录 data/（含留痕数据库与输出文件）。
如不再需要这些数据，请在卸载后手动删除该目录。

Every PrivaMask feature (scanning, detection, masking, restore, auditing) runs on your machine. The app contains no networking code, telemetry, analytics or account system, and uses no cookies.
| Data | Location | Notes |
|---|---|---|
| Audit database | data/privamask.db (SQLite) in the app's local data folder | File hashes before/after, file names before/after masking, original and output paths (positions), replacement mappings |
| Masked results | Task output folder data/output/<task timestamp>/ (original relative structure preserved) | Masked copies; your source files are read-only |
| Restored files | data/output/restore/<task timestamp>/ | Files produced by restore |
| Rules & settings | Same local database | Masking rules, audit switch and other UI settings |
This data exists only on your computer and is never sent to any server.
The exported mapping workbook (xlsx) and the audit database contain mappings to the original (pre-masking) values — whoever holds them can restore the masked data. Keep them safe and clean them up as needed; the restore screen in the app provides per-task audit cleanup.
Masking never modifies, moves or deletes your source files; all results are written as new files into the output folder.
Uninstalling the app does not automatically delete the data folder data/
(the audit database and output files). If you no longer need this data, delete the folder manually after uninstalling.
