1. 服务与联系
本政策说明 PDF2Translate 当前版本如何处理数据。服务标识为 PDF2Translate;隐私请求请联系 support@pdf2translate.com。
2. 本地文档与云端处理
原始 PDF、书架、笔记及阅读缓存保存在当前浏览器的 IndexedDB,不自动跨设备同步。打开 PDF 不会把整本原件上传保存到我们的服务器。使用翻译时,需要处理的文字会经我们的 API 发往阿里云百炼;使用 OCR 时,当前页渲染图片会经 API 发往百炼。整理页面排版时,当前页图片、候选文字块及位置信息可能经 API 发往 Cloudflare Workers AI 上的 TypeSafe Jev,用于判断页眉、图注和段落关系;文字版原文提取也可能使用该辅助流程。请仅处理你有权提供的内容;不要提交不适合交由这些服务处理的资料。
3. 账号、处理结果与账务
服务端保存邮箱、密码哈希、验证状态、会话及必要的安全记录;不以明文保存账号密码。服务端还保存 AI 任务状态、内容指纹、翻译结果或 OCR 提取结果、模型和 Token 用量,以及积分批次、消费与退还流水、订单金额、支付渠道、交易号和时间。内容指纹不等于原文,但结果本身可能包含文档内容;账号及账务记录也不是匿名数据。
4. 服务提供方
Cloudflare 提供 Pages、Workers、D1、网络及安全服务,并通过 Workers AI 接入 TypeSafe Jev 辅助版面判断;阿里云百炼提供 DeepSeek 翻译和 Qwen OCR;Resend 接收邮箱地址及验证或重置邮件内容以发送邮件;选择微信支付时,zpay 处理订单、金额、客户端 IP 和支付交易信息。我们不通过本服务收集银行卡密码、微信支付密码或短信支付验证码。服务提供方可能按其条款处理或留存数据,不承诺所有数据只在中国境内处理,也不承诺零留存。
5. 浏览器存储与安全日志
浏览器 localStorage 保存登录令牌和界面偏好;IndexedDB 保存文档与本地阅读资料。支付中间状态可能暂存在 sessionStorage。请求 IP、访问时间和错误标识可能用于限流、安全与排障。请保护设备访问权限,妥善保管 PDF 原件和导出资料;清除本网站数据可能删除本地书架、笔记及缓存,不能据此认定服务端记录已删除。
6. 留存、查询与删除请求
当前版本未对 AI 处理结果和账号、订单、积分流水设置统一的自动删除期限;这些数据会留存以支持任务恢复、账号服务、对账与争议处理。验证邮件和重置令牌通常30分钟失效,刷新会话通常30天到期;到期的临时记录由定时任务清理。可通过联系邮箱申请查询、更正、删除账号或处理结果;我们会核验账号归属,并说明可删除的范围、进展及必须继续保留的账务或安全记录。当前没有自助账号注销入口,不承诺申请后立即清空所有副本或第三方记录。
7. 模型数据说明与更新
百炼公开隐私说明表示不会将客户数据用于模型训练,同时说明调用产生的数据可能按相关服务协议留存;本服务没有承诺或启用专门的零留存能力。具体提供方规则请查看下方官方链接。本政策重大变更会在网站公布,并尽可能通过站内提示或邮件通知。

Privacy Policy
Current status: WeChat credit purchases are available, with no automatic renewal. Email-verified accounts receive 50 credits.
1. Service and contact
This policy describes data handling in the current PDF2Translate service, identified as PDF2Translate. Contact support@pdf2translate.com for privacy requests.
2. Local files and cloud processing
Original PDFs, library items, notes and reading caches are stored in the current browser using IndexedDB, without automatic cross-device sync. Opening a PDF does not upload the entire original for server storage. Translation sends the required text through our API to Alibaba Cloud Model Studio; OCR sends an image of the selected page. Layout assistance may send that page image, candidate text blocks and positions through our API to TypeSafe Jev on Cloudflare Workers AI to identify page furniture, captions and paragraph relationships. Text-based PDFs may also use this assistance. Only submit content you are authorized to provide and consider whether these services are suitable for that content.
3. Accounts, results and billing records
The server stores email addresses, password hashes, verification state, sessions and necessary security records, rather than plaintext account passwords. It also stores AI task state, request fingerprints, translation or OCR results, models and token usage, plus credit batches, debits, returns, order amounts, payment channels, transaction references and timestamps. Fingerprints are not the original input, but stored results can contain document content. Account and billing records are not anonymous.
4. Service providers
Cloudflare provides hosting, compute, database, network and security services, and access to TypeSafe Jev through Workers AI for layout assistance. Alibaba Cloud Model Studio provides DeepSeek translation and Qwen OCR. Resend receives your email address and verification or reset message content to deliver mail. For WeChat payments, zpay handles order details, amounts, client IP addresses and payment transaction data. We do not collect bank or WeChat payment passwords or payment verification codes through this service. Providers may process or retain data under their own terms. We do not promise China-only processing or zero retention.
5. Browser storage and security logs
Browser localStorage holds login tokens and preferences, IndexedDB holds local documents and reading data, and sessionStorage may hold pending-payment state. Request IP addresses, access times and error identifiers may be processed for rate limiting, security and diagnostics. Protect device access and keep your original PDFs and exports. Clearing site data may delete local files, notes and caches, but does not itself delete server records.
6. Retention, access and deletion requests
The current version has no single automatic deletion period for AI results, accounts, orders or credit ledgers. Records remain for recovery, account services, reconciliation and disputes. Email-verification and password-reset tokens normally expire after 30 minutes; refresh sessions normally expire after 30 days. Scheduled jobs remove expired temporary records. You may request access, correction, account deletion or result deletion by email. We will verify ownership and explain the scope, progress and billing or security records that must remain. There is no self-service account deletion flow, and we do not promise immediate removal of every copy or third-party record.
7. Model data and updates
Model Studio publicly states that it does not use customer data for model training, while noting that call data may be retained under its service agreement. This service does not promise or configure a special zero-retention capability. Refer to the provider links below. Material policy changes will be published on the site and, where practicable, highlighted in the service or by email.
