Privacy Policy

Last updated: October 27, 2026. This Privacy Policy describes how DeepSeek V4 Hub (deepseekv4pro.com) collects, uses, and shares your personal information.

Who Is Responsible for Your Information

Hangzhou Wanwu Qi Technology Co., Ltd. operates DeepSeek V4 Hub and is responsible for the personal information we process to operate this website. Business location: Hangzhou, Zhejiang, Mainland China.

For privacy questions, complaints, or requests to exercise your rights, email contact@deepseekv4pro.com. Payment providers also process transaction information under their own privacy notices, as described below.

1. Information We Collect

Account Information

When you create an account, we collect your name, email address, and authentication credentials provided through our third-party authentication provider (Clerk).

Restock Requests

If you request a restock notification, we store your email address, selected plan, and consent date so our team can contact you about that plan. Registration does not reserve stock or start a paid subscription. We use short-lived hashed network identifiers to limit automated submissions. You can ask us to remove your registration by emailing contact@deepseekv4pro.com.

Usage Data

We automatically collect information about how you interact with our services, including pages visited, features used, API calls made, timestamps, and referring URLs.

Chat and AI Inputs

Chat sends your submitted messages to DeepSeek to generate a response. When you use saved chat history, conversation titles, your messages, and generated replies are stored in our Supabase database and associated with your account. The Arena sends your prompt to the selected model's configured provider or API intermediary. Managed API access also forwards submitted content to the upstream service needed to answer your request; usage and quota records include request metadata and token counts. Provider processing is subject to that provider's applicable terms. We do not promise zero retention by every provider.

Device Information

We collect device type, operating system, browser type, IP address, and general geographic location derived from your IP address.

Payment Information

If you purchase API keys or services, payment processing is handled by third-party providers. We do not store your full credit card number or payment credentials on our servers. We retain order references, the selected payment provider, amounts and currency, billing periods, payment and delivery status, and the version and time of checkout terms acceptance to deliver purchases and handle billing issues. The selected provider receives the account email, order and product details needed to process the transaction. For Waffo purchases, we also provide an account identifier to associate checkout and billing management with your signed-in account. Subotiz purchases, when offered, are processed under its Merchant of Record service and its Privacy Policy. Existing Stripe purchases remain associated with Stripe.

2. How We Use Your Information

We use the information we collect to:

  • Provide, maintain, and improve our services
  • Process transactions and deliver API keys
  • Send service-related communications (order confirmations, security alerts, support messages)
  • Analyze usage patterns to enhance user experience and platform performance
  • Detect, prevent, and address technical issues, fraud, or abuse
  • Comply with legal obligations

3. Information Sharing

We do not sell your personal information. We may share your information with:

  • Service Providers:

    Third-party companies that help us operate our platform (hosting, authentication, analytics, payment processing)

  • Legal Requirements:

    When required by law, regulation, legal process, or governmental request

  • Business Transfers:

    In connection with a merger, acquisition, or sale of assets

4. Cookies and Analytics

Strictly necessary cookies and local storage support account sessions, security, fraud prevention, checkout, and your privacy choices. Disabling this storage may prevent parts of the Service from working.

With your permission, Google Analytics may process device and browser information, IP-derived location, referring URLs, pages viewed, and interaction events to help us understand and improve the Service. Analytics storage is denied by default and is enabled only after you select "Allow analytics."

With your permission, Plausible records page views and selected actions such as account creation, plan clicks, checkout starts, and confirmed payments. We send plan, purchase mode, payment provider, and checkout page labels with those actions, but no account or order IDs. We load its script only after you select "Allow analytics" and stop sending events if you later choose "Essential only."

We do not display third-party advertisements or load advertising scripts. Advertising storage, advertising user data, and ad personalization remain disabled on this site.

5. Google Services and Your Choices

Google explains how it uses information from sites that use its services on its partner sites information page.

You can reopen this site's analytics choices at any time using the "Privacy choices" control in the footer. Withdrawing analytics consent affects future collection and does not require you to close your account.

6. Data Security

We use HTTPS, account access controls, and encrypted storage for API credentials to protect service data. However, no method of transmission over the Internet is 100% secure, and we cannot guarantee absolute security.

7. Data Retention

We retain your personal information for as long as your account is active or as needed to provide services, limited to the shortest period necessary for the relevant purpose unless the law requires a longer period. Records needed for statutory retention, an unresolved dispute, or a legal claim may need to be retained after account closure. Analytics retention follows the configuration of our Google Analytics property. Aggregated or de-identified records may be retained where they no longer identify you. You may request deletion of your account and associated data by contacting us.

8. Your Rights

Depending on the law applicable to your information, you may have the right to:

  • Access and obtain a copy of your personal data
  • Correct inaccurate or incomplete data
  • Request deletion of your personal data
  • Object to or restrict certain processing activities
  • Data portability
  • Withdraw consent where processing relies on consent
  • Request an explanation of our personal information processing rules

To exercise these rights, please contact us at contact@deepseekv4pro.com.

9. Mainland China Personal Information Rights

Where the Personal Information Protection Law of the People's Republic of China applies, its mandatory protections govern the processing of your personal information. Mainland China in this policy refers to the jurisdiction in which that law applies, rather than the separate privacy laws of Hong Kong SAR, Macao SAR, or Taiwan.

Processing requires a lawful basis, such as your informed consent, necessity to enter into or perform a contract with you, or a statutory obligation, as applicable. Accepting our Terms or continuing to use the website is not blanket consent to optional processing. Refusing or withdrawing optional consent does not remove access to services that do not require that processing. Withdrawal does not affect the lawfulness of earlier processing based on consent.

You may request access, a copy, correction, completion, deletion where legally required, an explanation of processing, or transfer to another processor where statutory conditions are met. You may also request account closure or exercise a right to restrict or refuse processing. Send your request to contact@deepseekv4pro.com using your account email and describe the request. Do not include API keys, passwords, or full payment-card details. We may request proportionate verification before providing account information. If a request cannot be fulfilled, we will explain the reason; you retain the right to complain to a competent authority or seek a judicial remedy.

10. International Data Processing

Account, hosting, payment, analytics, and AI service providers may process information outside the country where you live. This policy does not represent that all information is stored in Mainland China.

For transfers governed by Mainland China personal information law, you are entitled to the legally required information about the overseas recipient, its contact details, processing purposes and methods, information categories, and procedures for exercising your rights. Any required separate consent must be obtained before the transfer; general acceptance of this policy is not a substitute. Any applicable transfer assessment, certification, standard contract, or other lawful transfer condition must also be satisfied. A legal exemption from one transfer mechanism does not by itself remove other applicable notice or consent duties.

11. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the updated policy on this page and updating the "Last updated" date, with additional notice where required by law. Where a change requires renewed or separate consent, that consent must be obtained before the relevant processing begins. Continued use alone does not supply that consent.
