PrivatePDF Privacy Policy
Last updated: August 27, 2026
Your documents stay on your PC. PrivatePDF is designed for fully offline document processing.
PrivatePDF does not upload documents, page images, OCR text, redaction selections, passwords, file paths, or usage data to PrivatePDF or any third party.
PrivatePDF requires no account and contains no advertising, analytics, telemetry, or remote model downloads. Microsoft Store may process purchases and licensing under Microsoft's privacy terms. PrivatePDF receives only the entitlement status required to unlock purchased features.
Document processing, OCR, detection, conversion, redaction, cleaning and ordinary signing run entirely on the device. If you explicitly enable an RFC 3161 document timestamp while signing, PrivatePDF sends only a cryptographic document hash, algorithm identifier and request nonce to the timestamp authority URL you selected, and receives a signed timestamp token in return. The PDF, extracted text, certificate password and signature drawing are not transmitted. This optional request is disabled by default, and PrivatePDF does not retain the timestamp URL after the signing session.
Settings and an encrypted Microsoft Store entitlement cache may be stored locally. Recent-document lists, document contents, OCR results, and sensitive paths are not retained by default. If you explicitly enable optional reading-progress, recent-file, tab-restoration, or privacy-work recovery features, the selected local state is protected for the current Windows user and can be disabled again in Settings. Temporary processing data is deleted after each job, and stale session data is cleaned after an interrupted run.

PrivatePDF 隐私政策
更新日期:2026 年 8 月 27 日
你的文档始终留在本机。 PrivatePDF 专为完全离线的文档处理而设计。
PrivatePDF 不会向 PrivatePDF 或任何第三方上传文档、页面图像、OCR 文字、脱敏区域、密码、文件路径或使用数据。
PrivatePDF 无需账号,不包含广告、分析、遥测或远程模型下载。微软商店可能依据其隐私条款处理购买与授权;PrivatePDF 只读取用于解锁已购功能的授权状态。
文档处理、OCR、检测、转换、脱敏、清理和普通签名均在本机完成。只有当你在签名时明确启用 RFC 3161 文档时间戳,PrivatePDF 才会向你选择的时间戳机构发送文档的加密哈希、算法标识和请求随机数,并接收签名时间戳令牌。PDF、提取文字、证书密码和签名图案不会被传输。此功能默认关闭,签名会话结束后也不会保留时间戳服务地址。
应用可能在本地保存设置和加密的微软商店授权缓存。默认不保留最近文档、文档内容、OCR 结果或敏感路径。你明确启用阅读进度、最近文件、标签恢复或隐私工作恢复后,所选本地状态仅供当前 Windows 用户访问,并可随时在设置中再次关闭。任务完成后会删除临时处理数据,并在异常中断后的下次启动清理残留会话。
