Feb 11, 2026

Introduction

Welcome to D-Chat (deepseekv4.space). D-Chat is an independent AI chat product that provides a custom interface for supported third-party models. This policy explains what data we collect, how we use it, and who may process it on our behalf.

What We Collect

  1. Account Information

    • If you create an account, we may collect your email address, login method, display name, and basic account identifiers.

  2. Chat and Product Usage Data

    • We may store prompts, chat history, model selections, tool usage, and generated responses so the product works correctly and your history is available to you.

  3. Billing and Subscription Data

    • If you start a paid plan, we may store subscription identifiers, invoice references, plan details, transaction metadata, and billing status. Payment card details are handled by payment processors, not stored directly by us.

  4. Support Communications

    • If you contact support, we may store your email address and message content so we can respond and resolve billing or product issues.

  5. Technical and Usage Logs

    • We may collect IP address, request headers, timestamps, device/browser information, referrer data, and basic analytics for reliability, abuse prevention, and product improvement.

  6. Cookies

    • We may use essential, preference, or analytics cookies to keep the site stable, maintain sessions, and understand aggregate usage.

How We Use Data

We use collected data to:

  • Operate, secure, and improve D-Chat
  • Authenticate users and maintain accounts
  • Provide chat history, billing, and subscription features
  • Process payments and prevent fraud
  • Respond to support requests
  • Comply with legal obligations

Data Sharing

We do not sell your personal information. We may share limited data with trusted service providers when needed to operate D-Chat, including providers for hosting, analytics, authentication, payment processing, customer support, and AI inference. This may include payment processors such as Creem or Stripe and AI providers that process prompts so a response can be generated. We may also disclose data when required by law or to protect our rights, users, or systems.

Data Retention

We retain data only as long as needed for the purposes listed above, unless a longer retention period is required by law, fraud prevention needs, billing records, or security obligations.

Your Choices

You can disable non-essential cookies in your browser settings. You may also request access, correction, or deletion of account or support data that we control, subject to legal, billing, fraud-prevention, and security requirements.

Policy Updates

We may update this policy from time to time. The latest version will always be published on this page with the updated date.
