POLICIES

Privacy Policy

Effective date: 24 October 2026.

Paperless Tools is operated by Guangzhou Sunxingzhe E-commerce Co., Ltd., an English rendering of the company's registered name in China, not a separate legal entity. Contact derotuibs@gmail.com about this policy or a request concerning your information.

Free PDF tools

For the free PDF tools, the PDF files you select are processed in your browser and are not uploaded to our server. The site has no advertising trackers or third-party analytics in its own code. The separate AI workspace receives only text you choose to submit after review and consent.

First-party usage statistics

We count page views and fixed steps for the free PDF merge, page extraction, rotation and text-preview tools: tool opened, PDF selected, processing started, processing failed or succeeded. This helps us find broken or confusing steps. The statistics request contains only the event type and a random identifier for the current browser tab's session, which changes at least daily. It does not include your PDF, file name, file size, document text, account, email address or advertising identifier. We do not use a third-party analytics service or an analytics cookie. The random identifier is kept in your browser's session storage; on our server it is stored only as a one-way daily hash. We retain daily counts and these hashes for up to 30 days, then remove them. Counts are approximate, can include automated traffic, and are not proof of unique people. We honor supported Global Privacy Control and Do Not Track signals for this first-party usage counter.

Technical and contact information

When you visit the site, our hosting service may process standard technical information such as your IP address, request time, requested page, and browser user agent in server access and security logs. We use this information to serve the site, troubleshoot problems, and protect it from abuse. The site is hosted on a Vultr server in the United States. If you email support, we process your email address and message to respond; the support mailbox is provided by Google. These providers may process information outside your country.

We retain technical logs and support messages only as needed for the above purposes and applicable recordkeeping duties. You may contact us to ask about access, correction, or deletion of information relating to you, subject to applicable law and our ability to identify the relevant records.

Accounts, billing and AI documents

For accounts, we store your email address, a salted password hash, verification status, session records and necessary security and usage records. A secure, HttpOnly session cookie is used for sign-in; it expires after eight hours. Account-related emails are sent through Resend. Paddle processes checkout and billing as merchant of record; we keep payment and subscription identifiers, paid-period and credit records needed to provide service and handle refunds, rather than storing card numbers.

In the AI workspace, a selected PDF is read in your browser. The PDF file itself is not uploaded. Only after you review the extracted or pasted text and explicitly choose to submit a task, we send that text, the selected task and language, and any question through our server to the official DeepSeek API. Do not submit secrets, sensitive personal information, or documents you are not entitled to share. Your Paperless Tools password and account email are not included in the model prompt by our application.

Our application does not persist the submitted source text or question in its document ledger. It stores the generated answer, which may contain information from your document, for retrieval for up to 24 hours. You can delete your saved answer in the workspace. A scheduled application cleanup removes expired answers while the service is running. Usage, task identifiers, input fingerprints, credit records and estimated costs are kept separately for security, accounting and duplicate-request protection. Deleting an answer does not restore a used credit or erase those records.

The 24-hour retrieval window is not a promise that all database remnants, server backups or provider copies are erased within 24 hours. Backup retention and provider-side API retention and reuse have not yet been verified for this deployment. We do not promise zero retention or that API content will never be used for model improvement. Read DeepSeek's privacy policy before sharing text. Questions about this restricted evaluation can be sent to our support address above.

Our application server is in the United States and the operator is registered in China. Submitted text is also processed by DeepSeek, a China-based provider; account emails and support may be processed by Resend and Google outside your country. Billing information is processed by Paddle. These providers may process data in other countries. Do not submit sensitive information that you are not comfortable sharing with these providers. Contact us at the address above about access or deletion requests; transaction records may need to be retained for legal and accounting reasons.

Chinese quote to English product sheet

If you choose this separate one-time service, we upload the CSV or XLSX file you select to our United States server for validation. The server stores the normalized source rows and associates them with your verified account and order. Only after you explicitly confirm that you are allowed to share the content do we send the product text fields to DeepSeek for an English draft; price, minimum order quantity and currency remain in our generated workbook and are not intentionally included in the model prompt. Your account password and payment-card details are not sent to DeepSeek by our application.

The generated workbook contains an English draft and a separate source worksheet. The download is available only to the purchasing account for up to seven days after generation. An application cleanup removes the workbook and source rows after that window while the service is running. A source submitted without starting checkout is removed after seven days. Unsettled payments or a failed generation may require us to retain the source temporarily for reconciliation and support; contact us to request review or deletion where applicable. Order identifiers, transaction and refund records may be retained for accounting, security and dispute handling. These application periods do not guarantee deletion of backups or copies held by Paddle or DeepSeek on the same schedule.
