Citizenship Support
Help with scanning files, understanding evidence, privacy controls, and the share extension.
If you need help, email [email protected]. Include the app version, device model, iOS version, and a description of what happened. Do not send private files unless support asks for them.
Getting started
- Open Citizenship and choose Photos, Files, or Paste, or use the system Share sheet from a supported app.
- Citizenship reads evidence already carried by the selected file on your device. It does not upload the file for a scan.
- Open a result to see the evidence layer and the reason for the wording shown.
Understanding a result
A signed Content Credential can show who signed a file and whether it changed after signing. Metadata, labels, and watermarks are weaker signals. “No AI indicators found” does not prove a file is authentic: screenshots, exports, and re-saves often remove provenance.
Common questions
The Share option is missing
First open Citizenship once, then use the system Share sheet and choose More to enable Citizenship. The extension appears only for supported file types.
Why can’t the app decide?
Some files do not retain enough evidence to support a reliable conclusion. Citizenship reports that limitation rather than guessing.
How do I remove history?
Open Settings and turn off Keep history, or use History to clear saved results. Scan files themselves are never uploaded.
Citizenship 支持
获取文件检测、证据解读、隐私控制和分享扩展方面的帮助。
需要帮助时，请发送邮件至 [email protected]。请说明 App 版本、设备型号、iOS 版本和问题现象。除非支持人员明确要求，请不要发送私密文件。
开始使用
- 打开 Citizenship，选择「照片」「文件」或「粘贴」；也可从支持的 App 使用系统分享面板。
- Citizenship 只在设备上读取所选文件已有的证据，不会为检测上传文件。
- 打开检测结果可查看证据层级和对应文案的依据。
如何理解结果
已签名的内容凭证可以说明谁签署了文件，以及签署后文件是否被修改。元数据、可见标识和水印属于较弱信号。「未发现 AI 痕迹」并不证明文件真实：截图、导出和另存经常会移除溯源信息。
常见问题
分享面板里没有 Citizenship
先至少打开一次 Citizenship，然后在系统分享面板中选择「更多」并启用 Citizenship。扩展仅会对支持的文件类型显示。
为什么应用无法给出结论？
部分文件没有保留足以支持可靠结论的证据。Citizenship 会如实说明这一限制，而不会猜测。
如何删除历史记录？
在「设置」中关闭「保留历史记录」，或在「历史」中清除已保存的结果。检测文件本身不会被上传。
