Privacy Policy

Effective Date: July 12, 2026
Last Updated: July 12, 2026

Welcome to Chat-Deep.ai (“Chat-Deep.ai,” “we,” “us,” or “our”). This Privacy Policy explains how information is collected, used, disclosed, transferred, and retained when you visit our website, use our browser-based AI chat, contact us, post a comment, or interact with our analytics, advertising, consent, security, and infrastructure services.

Chat-Deep.ai is an independent website and is not the official DeepSeek website, official DeepSeek Chat, official DeepSeek app, official login page, or official developer platform. Our browser chat uses the DeepSeek API to generate responses. DeepSeek is operated by Hangzhou DeepSeek Artificial Intelligence Co., Ltd. (“DeepSeek”). Using DeepSeek technology does not imply that DeepSeek owns, operates, sponsors, certifies, or endorses Chat-Deep.ai.

This Policy applies only to Chat-Deep.ai. Your use of the Site is also governed by our Terms of Service and Cookie Policy.

Quick Summary

• You can use the normal Chat-Deep.ai browser chat without creating a Chat-Deep.ai account.
• We do not ask for your official DeepSeek password, API key, billing details, or login credentials.
• Prompts and relevant conversation context are sent to the DeepSeek API to generate responses.
• DeepSeek’s public privacy policy expressly states that it does not directly govern the personal information of users of downstream developer applications such as Chat-Deep.ai. This Chat-Deep.ai Privacy Policy governs our collection and use of your information.
• We do not sell chat messages or use chat content to create advertising profiles.
• Recent conversation history may be stored locally in your browser. You can remove it through the chat interface, where available, or by clearing Site data in your browser.
• Privacy Mode prevents new conversations from being saved in your browser. It does not prevent your prompt and relevant conversation context from being transmitted to Chat-Deep.ai and the DeepSeek API to generate a response.
• If you use voice input, speech recognition is provided by your browser, device, or platform. Chat-Deep.ai receives the resulting transcript when it is submitted to the chat.
• We use Google Analytics for site measurement and Google AdSense for advertising. Non-essential technologies are subject to consent where required.
• We use hosting, LiteSpeed, and QUIC.cloud services for functions such as content delivery, caching, performance, availability, and security.
• AI responses may be inaccurate or incomplete and must not be treated as professional advice or the sole basis for important decisions.

Who Controls Your Information

For personal information processed through Chat-Deep.ai, the operator of Chat-Deep.ai is the controller unless this Policy states otherwise. Our service providers may act as processors, independent controllers, or recipients depending on the service and applicable law.

How the AI Chat Works

1. You enter a prompt in the Chat-Deep.ai browser interface.
2. Your browser sends the prompt to Chat-Deep.ai’s application infrastructure.
3. We transmit the prompt, relevant previous messages, and technical instructions required to generate a response to the DeepSeek API.
4. DeepSeek processes the submitted input and returns an AI-generated output.
5. Chat-Deep.ai returns the output to your browser. Where local history is enabled, the conversation may be saved in your browser’s local storage.

The content submitted to DeepSeek may include your current prompt, the prior messages needed to maintain conversational context, and system or formatting instructions used to operate the chat. We do not require your name, email address, telephone number, payment information, or official DeepSeek account credentials for normal browser chat use. However, any personal information that you voluntarily type into a prompt becomes part of the content processed to generate the response.

DeepSeek API Processing

Our browser chat uses API services provided by Hangzhou DeepSeek Artificial Intelligence Co., Ltd. We delegate the processing of prompts and relevant conversation context to DeepSeek for the purpose of generating requested AI responses, maintaining the API service, preventing abuse, enforcing applicable terms, and meeting legal or security obligations.

DeepSeek’s official Privacy Policy states that its policy does not cover personal information collected from end users of downstream systems or applications developed through the DeepSeek Open Platform. Chat-Deep.ai therefore remains responsible for describing our processing rules and responding to privacy requests relating to our service. You may review DeepSeek’s official Privacy Policy and Open Platform Terms for additional information about DeepSeek.

DeepSeek’s publicly available Open Platform terms do not publish a fixed retention period that applies to every API prompt submitted through downstream applications. We therefore do not promise that DeepSeek provides immediate deletion, zero retention, or a specific retention period for API inputs and outputs. DeepSeek may retain or otherwise process information as permitted by its applicable terms, account settings, contractual arrangements, security requirements, and legal obligations.

We also do not claim that DeepSeek never uses API data to improve its services unless that limitation is confirmed by the applicable API account setting or written agreement. If a DeepSeek account control or contractual term governs model-improvement use, the processing will follow that setting or agreement. Avoid submitting any information that should not be processed by an external AI provider.

No Chat-Deep.ai Account Required

Normal browser chat use does not require a Chat-Deep.ai account. We do not ask you to provide a username, password, telephone number, payment method, or official DeepSeek credentials to start a normal chat. The DeepSeek API key used by Chat-Deep.ai is managed on the server and should never be requested from or exposed to visitors.

Local Browser History and Server Processing

Local conversation history is enabled by default and may store up to 50 recent conversations in your browser. Local records may include prompts, outputs, reasoning content where returned, chat titles, and timestamps. You can remove local history through the “Clear Chat” function, if available, or by clearing cookies and Site data in your browser settings. Removing browser history does not necessarily delete information already processed or retained by DeepSeek or technical providers.

Privacy Mode

Privacy Mode prevents new conversations from being saved in your browser’s local chat history. It does not make a chat request private from the systems required to answer it, and it is not a zero-retention guarantee. Your prompt and relevant active-conversation context are still transmitted to Chat-Deep.ai’s server and the DeepSeek API to generate a response.

Chat-Deep.ai does not intentionally maintain a permanent, account-based server-side conversation history for normal browser chat use. This does not mean that chat processing is “zero retention.” Prompts and responses must pass through our application infrastructure and may be handled temporarily in memory or captured in limited security, abuse-prevention, diagnostic, or error records. DeepSeek’s processing and retention are separate from Chat-Deep.ai’s local-history design.

Voice Input

If you use the voice-input feature, speech recognition is provided through capabilities made available by your browser, device, operating system, or platform provider. Microphone audio may be processed locally on your device or by a speech-recognition service operated by that provider, depending on your browser and device configuration. Chat-Deep.ai receives the resulting text transcript when you submit it to the chat and handles that transcript like any other prompt. Browser and platform providers process voice information under their own privacy policies and settings.

How We Use Information

• Provide the website and the AI chat response you request.
• Send prompts and relevant context to the DeepSeek API.
• Protect the Site, API integration, visitors, and service providers from abuse, fraud, bots, scraping, attacks, or unauthorized use.
• Apply rate limits, fair-use restrictions, moderation, and security controls.
• Troubleshoot errors, monitor availability, and improve reliability and usability.
• Measure website traffic and understand which public pages are useful.
• Display and measure advertising and prevent invalid ad traffic.
• Respond to inquiries, privacy requests, security reports, and legal notices.
• Comply with applicable laws, enforce our terms, and protect rights and safety.

Legal Bases for Processing

Where applicable law requires a legal basis, we rely on one or more of the following:

• Providing a service you request: processing your prompt and delegating the required processing to DeepSeek so that an AI response can be returned.
• Legitimate interests: securing the Site, preventing abuse, maintaining reliability, debugging errors, understanding aggregate usage, enforcing our terms, and protecting rights and safety.
• Consent: using non-essential analytics, advertising, personalization, or similar technologies where consent is required.
• Legal obligations: retaining or disclosing information when required to comply with law, legal process, regulatory duties, or valid government requests.

Where consent is the legal basis, you may withdraw it through the available cookie or privacy settings or by contacting us. Withdrawal does not affect processing that occurred before withdrawal.

Cookies, Analytics, Advertising, and Consent

We use cookies, local storage, pixels, tags, consent strings, and similar technologies for essential functions, local chat history, security, consent management, analytics, advertising, performance, and fraud prevention. For a more detailed explanation, read our Cookie Policy.

Google Analytics

We use Google Analytics to measure how visitors use the Site. Google Analytics may process page views, session information, device and browser information, approximate location, traffic source, interactions, and analytics identifiers. We use these reports to improve public content, navigation, performance, and reliability. Learn more about how Google uses information from sites and apps that use its services.

Google AdSense

We use Google AdSense to display and measure advertisements. Google and its advertising partners may process cookie identifiers, device and browser information, IP address, approximate location, ad impressions, ad interactions, and fraud-prevention signals. Advertising may be personalized only where permitted and, where required, after consent. We do not intentionally submit private chat text to Google AdSense or Google Analytics as advertising or analytics event data.

You can manage Google advertising personalization through Google Ads Settings. You may also use the consent or privacy controls displayed on Chat-Deep.ai.

Consent Management

Where required by applicable law or Google policy, we request consent before activating non-essential analytics or advertising technologies. Our consent tools may process your choices, region, timestamp, consent string, and related technical information. If you reject or withdraw consent, we will limit or disable non-essential technologies where required. You may still see contextual or non-personalized ads.

Infrastructure, Content Delivery, and Security Providers

Chat-Deep.ai uses website hosting and LiteSpeed/QUIC.cloud infrastructure for functions that may include content delivery, caching, optimization, availability, performance, and security. These providers may process technical information such as IP addresses, requested URLs, timestamps, browser information, cache data, access or error logs, and security signals as needed to provide their services. QUIC.cloud explains its practices in its Privacy Policy.

Some browser-side libraries used to render and sanitize chat output or display code may be delivered through cdnjs.cloudflare.com, a content-delivery service operated by Cloudflare. When your browser requests those files, Cloudflare may receive technical request data such as your IP address, browser information, the requested file, referring page information, and timestamps under its Privacy Policy.

We may change hosting, infrastructure, security, or maintenance providers when reasonably necessary. We will update this Policy when a material provider change affects the processing described here.

How We Share Information

We do not rent personal information or sell chat messages. We disclose information only as reasonably necessary for the purposes described in this Policy:

• DeepSeek: prompts, relevant conversation context, and technical instructions are submitted to the DeepSeek API to generate responses.
• Hosting, LiteSpeed, and QUIC.cloud: technical, traffic, cache, performance, and security information needed to deliver and protect the Site.
• Google: analytics, advertising, consent, measurement, and fraud-prevention information through Google Analytics, Google AdSense, and related technologies.
• Email and form providers: information you submit when contacting us.
• Professional advisers: limited information where reasonably needed for legal, security, compliance, accounting, or dispute purposes.
• Public visitors: information you intentionally submit as a public comment or other public contribution.
• Authorities or other parties: where required by law, legal process, court order, regulatory request, or where reasonably necessary to protect rights, safety, security, users, or service providers.
• Business successors: information reasonably necessary in connection with a merger, acquisition, restructuring, financing, asset sale, or similar transaction, subject to applicable law and appropriate protections.

Sale, Sharing, and Targeted Advertising

We do not sell personal information for money and do not sell chat messages. However, some U.S. state laws define “sale,” “sharing,” “targeted advertising,” or “cross-context behavioral advertising” broadly. Under those definitions, the use of Google advertising cookies or similar technologies may be considered sharing or targeted advertising even when we do not receive money in exchange for personal information.

You may opt out where applicable by using the Site’s cookie or privacy controls, using Google Ads Settings, enabling a legally recognized opt-out preference signal where supported, or emailing info@chat-deep.ai with the subject “Do Not Sell or Share Request.”

Data Retention

We retain personal information only for as long as reasonably necessary for the purposes described in this Policy, including providing the service, maintaining security, resolving disputes, enforcing agreements, and meeting legal obligations. Retention depends on the type, sensitivity, purpose, provider settings, and applicable law.

• Local chat history: remains in your browser until you clear it or browser storage is otherwise removed.
• Chat-Deep.ai application processing: prompts and responses are processed to complete requests. We do not create permanent account-based chat history for normal use, but limited operational, error, security, or abuse-prevention records may exist for a reasonable operational period.
• DeepSeek API processing: governed by DeepSeek’s applicable terms, API account settings, contractual arrangements, security requirements, and legal obligations. No single fixed API retention period is promised by Chat-Deep.ai.
• Contact messages: retained until the request is resolved and for a reasonable period afterward where needed for support, security, legal, dispute, or record-keeping purposes.
• Analytics and advertising data: retained according to Google settings, policies, consent choices, and applicable law.
• Technical and security logs: retained for a limited operational period or according to provider settings, and longer only where needed for security, fraud, abuse, legal, or dispute purposes.
• Consent records: retained as long as reasonably necessary to manage your choices and demonstrate compliance.

International Data Transfers

Chat-Deep.ai is available internationally, and our providers may process information in countries other than the country where you live.

DeepSeek and China: Prompts and relevant conversation context are transmitted to the DeepSeek API, operated by Hangzhou DeepSeek Artificial Intelligence Co., Ltd. in China. This processing may involve an international transfer of personal information to China. DeepSeek’s public Privacy Policy states that personal information covered by that policy is directly collected, processed, and stored in the People’s Republic of China, while also stating that the policy does not directly govern users of downstream developer applications. We cannot guarantee that information submitted through our API integration remains in your country.

Other providers: Google, QUIC.cloud, hosting, email, consent, and security providers may process information in the United States and other countries where they or their subprocessors operate.

Where required by applicable law, international transfers may rely on contractual protections, data-processing terms, standard contractual clauses, consent, provider commitments, or other legally recognized transfer mechanisms. Laws and privacy protections in the receiving country may differ from those in your location.

Your Privacy Rights

Depending on your location and subject to applicable exceptions, you may have rights to:

• know whether and how we process personal information;
• request access to personal information;
• request correction of inaccurate information;
• request deletion or restriction where applicable;
• object to processing based on legitimate interests;
• withdraw consent where processing is based on consent;
• request portability where applicable;
• opt out of sale, sharing, targeted advertising, or certain model-improvement uses where applicable;
• appeal a privacy-request decision where applicable; and
• complain to a competent data protection authority.

How to Exercise Your Rights

Email info@chat-deep.ai or use our contact form. Describe your request and provide enough information for us to identify the relevant interaction. We may ask for reasonable verification before fulfilling a request.

Because normal chat use does not require an account, we may not be able to identify or retrieve information based only on your name or email address. If fulfilling a valid request requires action by DeepSeek or another processor, we will contact or coordinate with that provider as reasonably necessary and as required by applicable law. We will respond within the legally required period.

You will not be discriminated against for exercising an applicable privacy right.

Sensitive Information and Other People’s Data

Do not submit passwords, DeepSeek credentials, API keys, payment-card details, recovery codes, government identification numbers, precise location, biometric information, medical records, financial account data, confidential legal documents, private customer records, trade secrets, export-controlled information, children’s data, or other highly sensitive information.

You are responsible for the prompts you submit. Do not submit another person’s personal information, copyrighted material, confidential information, or proprietary data unless you have the rights, permission, and lawful basis required to do so. Information included in a prompt will be transmitted to DeepSeek and processed as described in this Policy.

AI-Generated Outputs and Automated Decisions

Responses produced through the chat are generated by artificial intelligence. They may contain errors, omissions, outdated information, bias, or unsuitable recommendations and are provided for informational and productivity purposes only. They do not represent DeepSeek’s views and do not constitute medical, legal, financial, accounting, employment, credit, housing, insurance, safety, or other professional advice.

Do not use an AI response as the sole basis for an important decision or action. Decisions that may materially or legally affect a person must include appropriate human review, verification, and any safeguards required by applicable law.

Chat-Deep.ai does not use its browser chat to make legal, employment, credit, housing, insurance, healthcare, education-admission, or similarly significant decisions about visitors.

Children’s Privacy

Chat-Deep.ai is not directed to children under 13, and a higher minimum age or parental authorization may apply in some jurisdictions. We do not knowingly collect personal information from children. Minors should use AI services only with appropriate parent, guardian, or educator supervision and should never submit sensitive information.

If you believe a child has provided personal information through Chat-Deep.ai, contact info@chat-deep.ai. We will review the request and take appropriate action where required.

Security

We use reasonable technical and organizational measures designed to protect information and the Site. Measures may include HTTPS encryption, server-side API-key handling, access controls, software updates, caching and delivery controls, rate limiting, abuse prevention, monitoring, and limited retention. Read our Security page for additional information.

No website, API, AI service, internet transmission, or storage system is completely secure. You are responsible for choosing what you submit, protecting your device and accounts, and avoiding sensitive or confidential prompts.

Third-Party Links

The Site may link to official DeepSeek resources, Google services, QUIC.cloud, app stores, documentation, news sources, and other third-party websites. Their privacy policies and terms govern your activity after you leave Chat-Deep.ai. We do not control and are not responsible for third-party privacy, security, content, or availability.

Changes to This Privacy Policy

We may update this Policy to reflect changes in the Site, DeepSeek API integration, infrastructure, legal requirements, analytics, advertising, consent tools, or privacy practices. We will update the “Last Updated” date when changes are published. Where required, we may provide additional notice or request renewed consent for a material change.
