PDF工具隐私政策
欢迎使用“PDF工具”（PDF Tool）。我们重视你的隐私和文档安全。本政策说明应用处理的信息、使用目的、第三方服务及你的选择。
一、我们处理的信息
- 文件与文档内容：仅在你主动选择或导入 PDF、图片等文件后，用于阅读、编辑、转换、合并、拆分、压缩、签名、加密、水印、页码和永久脱敏等功能。
- 照片与相机：在你选择相关功能时，用于导入图片、扫描文档、拍摄签名素材或生成 PDF。
- 设备与应用信息：可能包括设备型号、系统和应用版本、语言、网络状态、崩溃与性能信息，用于保障运行、排查故障和改善体验。
- 使用与广告信息：可能包括页面访问、功能操作、广告展示及交互、广告或应用标识和大致位置（由 IP 地址推断），用于统计分析、广告投放和防止重复计费。
二、文档如何存储和处理
PDF 和图片的编辑、转换及其他文档处理在设备本机完成。应用不会为了处理功能上传你的原始文档或生成文件。文件保存在应用沙盒或你主动选择的位置；只有当你主动分享、导出到其他服务或访问第三方网页时，相关内容才会交由你选择的服务处理。
为避免同一内容在保存或分享时重复消耗激励次数，应用会在本机数据库保存文件内容的 SHA-256 摘要及使用记录。摘要用于识别内容是否相同，不包含文件正文，也不能还原原始文件。删除应用可能会移除应用沙盒内的文件和相关记录，请自行备份重要文档。
三、权限使用
- 相册或文件访问：选择图片、PDF 和导出位置。
- 相机访问：扫描纸质文档或拍摄签名素材。
- 网络访问：展示广告、请求隐私同意、统计分析、反馈与帮助。
你可以在 iOS“设置”中管理相关权限。关闭权限可能导致对应功能不可用。
四、第三方服务
- Google Mobile Ads（AdMob）：用于开屏、横幅和激励广告，可能处理 IP 地址、设备或应用标识、广告展示与交互、诊断及性能数据。应用会在适用地区通过 Google User Messaging Platform 请求和管理广告同意。详情见 Google 隐私政策和广告 SDK 数据披露。
- 友盟+统计：用于分析页面访问、功能操作、处理成功或失败及应用稳定性，可能处理设备、系统、网络和应用使用信息。我们不会把 PDF 正文、图片内容、文件名、密码或用户输入文字作为自定义统计事件上传。详情见友盟+隐私政策。
五、信息共享与保留
我们不会出售你的文档或个人信息。除实现你主动选择的分享、法律法规要求或前述第三方服务的必要处理外，不会向其他主体提供你的文档内容。第三方服务的数据保留期限由其政策和适用法律决定；本机文件由你管理并可在应用内删除。
六、你的选择与权利
你可以删除本机文件、撤回系统权限，并在应用的隐私页面查看政策或打开适用的广告隐私选项。如需查询、更正或删除与我们相关的数据，请通过下方邮箱联系。请勿在邮件中发送密码、身份证件或未遮挡的敏感文档。
七、儿童隐私
本应用不以未满13周岁的儿童为目标，也不会明知而主动收集儿童个人信息。如监护人发现儿童在未经同意的情况下提供了个人信息，请联系我们处理。
八、政策更新与联系我们
功能、第三方服务或法律要求发生变化时，我们可能更新本政策。更新内容将在本页面发布，并以页面标注的生效日期为准。

PDF Tool Privacy Policy
Welcome to PDF Tool. We value your privacy and document security. This policy explains what information the app processes, why it is used, the third-party services involved, and the choices available to you.
1. Information We Process
- Files and document content: processed only after you select or import PDFs, images, or other supported files for reading, editing, conversion, merging, splitting, compression, signing, encryption, watermarking, page numbering, or permanent redaction.
- Photos and camera: used when you choose to import images, scan documents, capture signature material, or create PDFs.
- Device and app information: may include device model, system and app version, language, network status, crash, and performance information for reliability and troubleshooting.
- Usage and advertising information: may include page views, feature actions, ad impressions and interactions, advertising or app identifiers, and approximate location inferred from IP address for analytics, advertising, and duplicate-charge prevention.
2. Local Document Processing
PDF and image editing, conversion, and related document operations are performed on your device. The app does not upload source documents or generated files to provide these processing features. Files remain in the app sandbox or a location you select. Content is handled by another service only when you deliberately share or export it to that service or visit a third-party webpage.
To avoid consuming another rewarded use for identical content, the app stores a SHA-256 content digest and usage record in an on-device database. The digest does not contain document text and cannot reconstruct the original file.
3. Permissions
- Photos or files: selecting images, PDFs, and export locations.
- Camera: scanning paper documents or capturing signature material.
- Network: ads, consent requests, analytics, feedback, and help.
You can manage permissions in iOS Settings. Disabling a permission may prevent the related feature from working.
4. Third-Party Services
- Google Mobile Ads (AdMob): provides app-open, banner, and rewarded ads and may process IP address, device or app identifiers, ad impressions and interactions, diagnostics, and performance data. Where applicable, the app uses Google User Messaging Platform to request and manage advertising consent. See the Google Privacy Policy and Mobile Ads SDK disclosure.
- Umeng+ Analytics: measures page visits, feature actions, processing outcomes, and stability and may process device, system, network, and app usage information. Custom analytics events do not contain PDF text, image content, filenames, passwords, or user-entered document text. See the Umeng+ Privacy Policy.
5. Sharing and Retention
We do not sell your documents or personal information. Document content is not provided to others except when you initiate sharing, when required by law, or as necessary for the third-party services described above. You control on-device files and may delete them in the app. Third-party retention is governed by each provider's policy and applicable law.
6. Your Choices and Rights
You may delete local files, withdraw system permissions, view this policy in the app, and open advertising privacy options when required. To request access, correction, or deletion of data associated with us, contact the email below. Do not email passwords, identity documents, or unredacted sensitive files.
7. Children's Privacy
The app is not directed to children under 13 and does not knowingly collect their personal information. A guardian who believes a child provided information without consent may contact us.
8. Updates and Contact
We may update this policy when features, third-party services, or legal requirements change. Updates will be posted here with a revised effective date.
