Privacy Policy

Effective Date: July 14, 2026
Last Verified: July 14, 2026

This Privacy Policy explains how Chat-Deep.ai collects, uses, discloses, transfers, and retains information when you visit the website, use the independent browser-based AI chat, contact us, post a comment, or interact with our analytics, advertising, consent, security, and infrastructure services.

Chat-Deep.ai is operated by Think For Digital Business, an Egypt-based company (“Think For Digital Business,” “Chat-Deep.ai,” “we,” “us,” or “our”). This Policy applies only to Chat-Deep.ai. Our Terms of Service and Cookie Policy also apply to your use of the service.

1. Independent Website and No Affiliation

Chat-Deep.ai is an independent website and browser chat service. It is not the official DeepSeek website, official DeepSeek Chat, official DeepSeek application, official login page, official developer platform, billing portal, or support channel. Our browser chat uses API services provided by Hangzhou DeepSeek Artificial Intelligence Co., Ltd. (“DeepSeek”) to generate responses. This technology-provider relationship does not mean that DeepSeek owns, operates, sponsors, authorizes, certifies, recommends, or endorses Chat-Deep.ai.

2. Data Controller and Contact Details

For personal information whose purposes and means of processing are determined by Chat-Deep.ai, the data controller is:

Our service providers may act as processors, independent controllers, or recipients depending on the service, contractual arrangement, and applicable law.

3. Important Notice About AI Chat Processing

When you submit a message through the Chat-Deep.ai browser chat, your prompt and the relevant active-conversation context needed to answer it are transmitted through Chat-Deep.ai’s application infrastructure to the DeepSeek API. This processing is necessary to generate and return an AI response.

Normal browser chat use does not require a Chat-Deep.ai account. We do not ask for your official DeepSeek password, DeepSeek API key, DeepSeek billing details, payment credentials, or official DeepSeek account information. However, any personal information you voluntarily type into a prompt becomes part of the content processed to generate the response.

Do not submit passwords, authentication codes, API keys, payment information, identity documents, medical records, financial account information, confidential business material, trade secrets, private customer records, children’s data, or other sensitive or regulated information.

4. How the Browser 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 needed for the active conversation, and technical or formatting instructions required to operate the chat 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. If local history is enabled, the conversation may be stored in your browser’s local storage.

Chat-Deep.ai does not intentionally maintain permanent, account-based server-side chat history for normal browser chat use. This is not a zero-retention promise. Requests must be processed temporarily, and limited operational, security, abuse-prevention, diagnostic, or error records may be created.

5. DeepSeek API Processing and Privacy Scope

DeepSeek’s consumer Privacy Policy applies to the DeepSeek services that link or refer to that policy. It expressly states that it does not govern the personal-data processing rules for end users of downstream applications developed through the DeepSeek Open Platform. Chat-Deep.ai is such a downstream application and is responsible for explaining its own processing practices and responding to applicable privacy requests.

You may review DeepSeek’s official Privacy Policy and Open Platform Terms of Service. Those documents do not create a universal public promise of zero retention, immediate deletion, a fixed retention period, exclusion from all service-improvement use, or one data-residency location for every downstream API request.

DeepSeek and the technical providers needed to deliver and secure an API request may process information under their applicable terms, account settings, contracts, security practices, and legal obligations. We therefore do not promise a provider-side retention or model-improvement restriction unless it is confirmed by the applicable account control or a written contractual commitment.

DeepSeek Context Caching

DeepSeek’s API documentation states that Context Caching on Disk is enabled by default for API users. The system may write reusable prompt prefixes to a disk cache. DeepSeek describes this cache as best effort and states that an unused cache is usually cleared within a few hours to a few days. Provider practices may change. Review DeepSeek’s official Context Caching documentation before submitting information that requires strict retention controls.

6. Information We Collect and Process

AI Chat Content

This may include prompts, questions, pasted text, relevant conversation context, chat settings, model or mode choices, technical instructions, and generated responses. We process this content to transmit the request to DeepSeek, return the requested response, maintain functionality, diagnose errors, enforce limits, and prevent abuse.

Local Chat History

Where enabled, up to 50 recent conversations may be stored in your browser’s local storage. Local records may include prompts, outputs, reasoning content where returned, chat titles, and timestamps. These records normally remain on your device until you clear the chat, clear Chat-Deep.ai site data, your browser removes the storage, or another person with access to the device removes it.

Technical, Security, and Log Data

This may include IP address, browser and device type, operating system, requested URL, timestamps, server or access logs, error details, rate-limit events, and security signals. We use this information to deliver and secure the service, diagnose failures, prevent fraud and abuse, apply fair-use limits, and maintain availability.

Analytics and Advertising Data

Google Analytics may process page views, sessions, approximate location, traffic source, device and browser information, interactions, and analytics identifiers. Google AdSense and advertising partners may process cookie identifiers, IP address, device and browser information, approximate location, ad impressions, interactions, consent signals, and fraud-prevention information.

Contact, Support, and Public Contributions

If you contact us, we may process your name, email address, subject, message, and information you voluntarily provide. If comments or public contributions are enabled, the name or nickname, comment, website field, moderation information, and associated technical information may be processed and displayed publicly.

Consent Records

Our consent tools may process consent status, selected choices, region, timestamp, consent string, or similar identifiers to remember and demonstrate cookie and advertising choices.

7. Local History and Privacy Mode

Privacy Mode prevents new conversations from being saved in your browser’s local chat history. It does not stop the prompt and relevant active-conversation context from being transmitted through Chat-Deep.ai’s infrastructure to the DeepSeek API. It is not an anonymous mode, offline mode, or zero-retention setting. Provider-side processing, context caching, temporary application processing, and limited security or diagnostic records may still occur.

Clearing browser history does not necessarily delete information already processed or retained by DeepSeek or another technical provider. Because normal chat use does not require an account, we may be unable to locate a particular chat record using only your name or email address.

8. Voice Input

If you use voice input, speech recognition is provided by capabilities made available by your browser, device, operating system, or platform provider. Microphone audio may be processed locally or by that provider, depending on your configuration. Chat-Deep.ai receives the resulting text transcript when you submit it and handles the transcript like any other prompt.

9. How We Use Information

  • Provide the website and AI chat response you request.
  • Transmit prompts and relevant context to the DeepSeek API.
  • Operate local chat history and user-selected settings.
  • Protect the website, API integration, visitors, and providers from fraud, bots, scraping, attacks, and unauthorized use.
  • Apply rate limits, moderation, fair-use restrictions, and security controls.
  • Troubleshoot errors and improve reliability, accessibility, navigation, and usability.
  • Measure public-page usage and content performance.
  • Display and measure advertising and prevent invalid traffic.
  • Respond to inquiries, privacy requests, security reports, complaints, and legal notices.
  • Comply with applicable law, enforce our terms, and protect rights, safety, and security.

10. Legal Bases for Processing

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

  • Providing a requested service or taking requested steps: processing a prompt and transmitting the required information to DeepSeek so that a response can be returned.
  • Legitimate interests: securing the service, preventing abuse, maintaining reliability, debugging errors, understanding aggregate usage, enforcing terms, and protecting rights and safety, where those interests are not overridden by applicable rights.
  • Consent: activating non-essential analytics, advertising personalization, or similar technologies where consent is required.
  • Legal obligations: retaining, using, or disclosing information when required by applicable law, legal process, or a valid regulatory or governmental request.

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

11. Cookies, Analytics, Advertising, and Consent

We use cookies, local storage, pixels, tags, consent strings, and similar technologies for essential functions, local history, preferences, security, analytics, advertising, performance, and fraud prevention. Read our Cookie Policy for more detail.

We use Google Analytics to understand public-page usage and Google AdSense to display and measure advertising. Advertising may be personalized only where permitted and, where required, after consent. We do not intentionally submit private chat text to Google Analytics or Google AdSense as analytics or advertising event data.

Where required by applicable law or Google policy, non-essential analytics or advertising technologies must not be activated until the required consent has been obtained. You can use the consent or privacy controls displayed on Chat-Deep.ai and may also manage Google advertising personalization through Google Ads Settings.

12. Hosting, Infrastructure, and Security Providers

Think For Digital Business is based in Egypt. The primary website and application server is hosted in the United States. Content delivery, caching, optimization, security, email, consent, analytics, and advertising services may process information in additional countries where their infrastructure or subprocessors operate.

Chat-Deep.ai uses hosting and LiteSpeed/QUIC.cloud services for functions that may include content delivery, caching, optimization, availability, performance, and security. These providers may process technical request data such as IP address, requested URL, timestamp, browser information, cache data, access or error logs, and security signals.

Browser-side libraries may be delivered through content-delivery services such as cdnjs.cloudflare.com. When your browser requests those files, the delivery provider may receive technical request information under its own privacy terms.

13. How We Disclose 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 required to generate responses.
  • Hosting and infrastructure providers: information needed to deliver, cache, secure, monitor, and troubleshoot the service.
  • Google and advertising partners: analytics, advertising, consent, measurement, and fraud-prevention information, subject to applicable consent choices.
  • Email, form, moderation, and support providers: information needed to deliver and protect messages or public contributions.
  • Professional advisers: limited information reasonably needed for legal, accounting, compliance, security, or dispute purposes.
  • Public visitors: information you intentionally publish as a comment or public contribution.
  • Authorities or affected parties: where required by law, legal process, court order, valid regulatory request, or to protect rights, safety, or security.
  • Business successors: information reasonably necessary for a merger, acquisition, restructuring, financing, asset transfer, or similar transaction, subject to applicable protections.

14. Sale, Sharing, and Targeted Advertising

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

Where an opt-out right applies, you may use the site’s consent or privacy controls, use a legally recognized opt-out preference signal where supported, manage Google advertising settings, or email info@chat-deep.ai with the subject “Do Not Sell or Share Request.”

15. Data Retention

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

  • Local history: remains in your browser until you remove it or browser storage is otherwise cleared.
  • Chat-Deep.ai application processing: prompts and outputs are processed to complete requests. We do not intentionally create permanent account-based chat history for normal use, but limited operational, security, error, or abuse-prevention records may exist for a reasonable operational period.
  • DeepSeek API processing: governed by DeepSeek’s applicable terms, API account settings, contracts, security requirements, caching practices, and legal obligations. Chat-Deep.ai does not promise one fixed provider-side retention period.
  • 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 information: retained according to provider configurations, policies, consent choices, and applicable law.
  • Technical and security logs: retained for a limited operational period or according to provider settings, and longer where reasonably needed for security, fraud, abuse, legal, or dispute purposes.
  • Consent records: retained as reasonably necessary to manage choices and demonstrate compliance.

16. International Data Transfers

Chat-Deep.ai is operated from Egypt and its primary server is hosted in the United States. Our providers may process information in other countries where they or their subprocessors operate. The laws and privacy protections in those countries may differ from the laws where you live.

Prompts and relevant conversation context are transmitted to the DeepSeek API, which is operated by a company established in China. This may involve processing in, transfer to, or access from China or other locations determined by DeepSeek’s applicable API terms, account settings, contracts, infrastructure, and legal obligations. DeepSeek’s consumer Privacy Policy must not be treated as a universal data-residency rule for every downstream API request.

Where applicable law requires a particular international-transfer safeguard, we will use a legally recognized mechanism available for the relevant transfer or restrict the affected processing when an appropriate mechanism is unavailable.

17. Your Privacy Rights

Depending on your location and subject to applicable limitations or 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, or targeted advertising where applicable;
  • appeal a privacy-request decision where applicable; and
  • complain to a competent data protection authority.

How to Exercise a Privacy Right

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 request reasonable verification before acting on a request.

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

18. Children and Teenagers

The service is primarily intended for adults. It is not directed to, and must not be used by, children under 13. If you are 13 or older but under 18, or under a higher minimum age required where you live, you may use Chat-Deep.ai only after your parent or legal guardian has reviewed the applicable Chat-Deep.ai and DeepSeek terms and privacy information and has consented to your use. If consent cannot lawfully be provided, do not use the service.

We do not knowingly collect personal information from children under 13. Minors must not submit personal contact information, credentials, payment information, identity documents, school records, health information, private images, or other sensitive information. If you believe a child has provided personal information through Chat-Deep.ai, contact info@chat-deep.ai. We will review the report and take action where required.

19. Sensitive Information and Other People’s Data

You are responsible for the content you submit. Do not provide another person’s personal information, confidential material, copyrighted content, or proprietary data unless you have the rights, authority, permission, and lawful basis required to do so. Privacy Mode does not make sensitive or confidential information suitable for submission.

20. AI-Generated Outputs

Chat responses are generated by artificial intelligence and are visibly presented as AI-generated content. Outputs may be inaccurate, incomplete, outdated, biased, offensive, fabricated, insecure, or unsuitable for your circumstances. They do not represent DeepSeek’s views and are not medical, legal, financial, tax, accounting, employment, credit, housing, insurance, cybersecurity, engineering, emergency, or other professional advice.

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

21. Security

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

No website, API, AI service, transmission, or storage system is completely secure. You are responsible for securing your device and browser and deciding what information is suitable to submit.

22. Third-Party Links and Services

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

23. Changes to This Privacy Policy

We may update this Policy to reflect changes in the service, API integration, infrastructure, providers, security practices, analytics, advertising, consent tools, or legal obligations. The date at the top will identify the version in effect. Where required, we will provide additional notice or request renewed consent before a material change takes effect.
