Privacy Policy

Last Updated: April 29, 2026

Welcome to Chat-Deep.ai (“Chat-Deep.ai,” “we,” “us,” or “our”). Chat-Deep.ai is an independent AI chat and DeepSeek guide website. It is not the official DeepSeek website, official DeepSeek Chat, official DeepSeek app, official DeepSeek login page, or official DeepSeek developer platform.

This Policy applies to our website, browser-based AI chat features, guides, contact forms, comments, analytics, advertising, security tools, and other services available through Chat-Deep.ai.

If we are required by applicable law to publish additional legal operator details, a postal address, a data protection officer, or a local representative, we will update this Policy with the relevant information.

Information We Collect and How We Use It

We aim to collect as little personal information as reasonably possible while still operating the website, providing the AI chat feature, improving reliability, protecting against abuse, responding to inquiries, and complying with legal obligations.

No Chat-Deep.ai Account Required

You can use the normal browser chat experience on Chat-Deep.ai without creating a Chat-Deep.ai account. We do not require your name, email address, password, phone number, payment information, or official DeepSeek login details to use the normal chat feature.

Do not enter official DeepSeek passwords, API keys, billing details, recovery codes, private credentials, confidential documents, or sensitive personal information into the chat.

AI Chat Processing

When you submit a prompt through the AI chat feature, your prompt and the generated response may be processed by an AI model provider, API provider, hosting provider, infrastructure provider, security provider, or technical delivery layer that helps us generate the requested response.

We use this processing to provide the chat response, maintain reliability, prevent abuse, troubleshoot errors, protect the service, and improve service safety. We do not use your chat messages for advertising profiling, and we do not sell your chat content.

Depending on technical availability, routing, configuration, and service reliability, the provider used to process a chat request may vary. Where a third-party provider processes your prompt or response, that provider may process the data according to its own terms, privacy policy, data retention practices, and security standards.

Chat-Deep.ai does not provide official DeepSeek account features, official DeepSeek login, official DeepSeek billing, official DeepSeek app management, official DeepSeek API key management, or official DeepSeek support. For official account, billing, API, app, legal, privacy, or support matters, use official DeepSeek resources directly.

Local Browser Chat History

Where available, recent chat history may be stored locally in your own browser for convenience. This local history is not an official account history and is not treated as permanent server-side storage by Chat-Deep.ai.

You can clear local chat history by using the “Clear Chat” function, if available, or by clearing the Site’s data from your browser settings. Once deleted, we cannot recover that local history for you.

Contact Forms, Emails, Comments, and Feedback

Contact Forms and Emails

If you contact us through our Contact Us form or by email, we may collect the information you choose to provide, such as your name, email address, message content, and any details needed to respond to your inquiry.

We use this information only to respond to you, investigate issues, provide support, maintain records, and protect our rights or users where necessary. We do not use contact form information for advertising profiling.

Comments and Public Feedback

If you post a comment, review, or public feedback on the Site, the information you submit may be visible to other visitors. Do not post sensitive personal information in public comments.

We may moderate, edit, refuse, or remove comments that violate our Terms of Service, contain spam, include harmful content, or create legal, safety, or security concerns.

Cookies and Similar Technologies

Cookies are small text files or identifiers stored on your device by a website, browser, or third-party service. Similar technologies may include local storage, pixels, tags, identifiers, consent strings, and security tokens.

We use cookies and similar technologies for security, core functionality, consent management, analytics, advertising, fraud prevention, performance, and service reliability. For more details, please read our Cookie Policy.

Some identifiers, such as cookie IDs, device identifiers, IP addresses, or advertising identifiers, may be considered personal data or personal information under certain privacy laws, even if they do not directly include your name, email address, or phone number.

Strictly Necessary Cookies

Strictly necessary cookies and similar technologies are used to make the website work, secure the service, remember essential preferences, manage consent choices, detect abuse, and prevent fraud or automated attacks. These technologies are not used by Chat-Deep.ai for advertising profiling.

Examples may include security cookies, consent preference cookies, session identifiers, anti-abuse signals, and Cloudflare security cookies.

Cloudflare and Security Cookies

We use Cloudflare for security, performance, content delivery, bot protection, caching, rate limiting, and protection against abuse. Cloudflare may process technical data such as IP address, browser information, device information, request timestamps, security events, and challenge results.

Cloudflare may use strictly necessary cookies or similar technologies such as __cf_bm, cf_clearance, _cfuvid, or similar identifiers where applicable. These technologies help distinguish legitimate traffic from bots, remember successful security challenges, manage rate limiting, protect the Site, and keep the service available.

Advertising Cookies and Google AdSense

We may display advertisements through Google AdSense and related Google advertising services. Third-party vendors, including Google, may use cookies to serve ads based on your prior visits to this Site or other websites. Google’s use of advertising cookies enables it and its partners to serve ads based on your visit to our Site and/or other sites on the Internet.

Advertising cookies and similar technologies may be used to serve ads, personalize ads where permitted and consented, measure ad performance, limit how often you see an ad, detect invalid traffic, prevent fraud, and support advertising security.

We do not receive your name, email address, phone number, or private chat content from Google AdSense. We also do not receive a list of your personal advertising interests. However, Google and advertising partners may process cookie identifiers, device data, browser data, IP address, approximate location, ad interactions, and similar signals according to their own policies and your choices.

You can learn more about Google advertising cookies and controls at: Google Advertising Privacy & Terms. You may also manage Google ad personalization through: Google Ads Settings.

You may also opt out of some third-party vendors’ use of cookies for personalized advertising by visiting industry opt-out tools such as: YourAdChoices.

Analytics Cookies and Google Analytics

We may use Google Analytics to understand how visitors use Chat-Deep.ai. Google Analytics may collect information such as page views, session duration, traffic source, device/browser type, approximate location, interactions, and analytics identifiers.

We use Google Analytics reports in aggregated or pseudonymous form to improve website content, performance, navigation, reliability, and user experience. We do not use Google Analytics to identify you by name, email address, or phone number.

Google Analytics may use cookies or similar technologies to collect and process data. Google explains how it uses information from sites and apps that use its services here: How Google uses information from sites or apps that use our services.

You may opt out of Google Analytics by using our cookie choices where available, blocking cookies in your browser, or installing the Google Analytics Opt-out Browser Add-on.

Consent, Cookie Choices, and Privacy Settings

Where required by applicable law or Google policy, we request consent before using non-essential cookies, local storage, or similar technologies, and before collecting, sharing, or using personal data for ads personalization.

For users in the European Economic Area, the United Kingdom, and Switzerland, Google’s EU user consent requirements may apply when Google products are used on the Site. Where required, our consent flow or consent management platform is intended to provide clear information, request legally valid consent, identify relevant parties, keep consent records, and allow you to change or withdraw your choices.

If you reject or withdraw consent for advertising or analytics cookies, we will limit or disable those technologies where required. You may still see ads, but they may be non-personalized or based on contextual information rather than your prior activity.

You can manage cookies and privacy preferences in the following ways:

• Use the cookie banner or consent preferences tool when it is shown.
• Use any “Cookie Settings,” “Privacy Settings,” or similar link made available on the Site.
• Read our Cookie Policy for more details.
• Use Google’s advertising controls through Google Ads Settings.
• Use the Google Analytics Opt-out Browser Add-on.
• Block or delete cookies through your browser settings.

Blocking cookies may affect some features, preferences, security checks, analytics, advertising, or site functionality. The core website may still work, but some features may be limited.

Do Not Track and Opt-Out Preference Signals

Some browsers offer “Do Not Track” signals or opt-out preference signals such as Global Privacy Control. Because there is no single global standard for all such signals, our response may depend on your location, applicable law, browser settings, and the capabilities of our consent tools.

Where required by applicable law and supported by our systems or consent tools, we will treat valid opt-out preference signals as a request to opt out of sale, sharing, targeted advertising, or similar processing. You may also contact us directly at info@chat-deep.ai.

Legal Bases for Processing

If you are located in a region where a legal basis is required, such as the European Economic Area, the United Kingdom, Switzerland, or another similar jurisdiction, we process personal data under one or more of the following legal bases:

• Consent: for non-essential cookies, personalized advertising, certain analytics, optional communications, or other processing where consent is required.
• Performance of a service you request: to process your chat prompt, generate a response, respond to your inquiry, or provide requested website functionality.
• Legitimate interests: to secure the website, prevent abuse, improve reliability, debug errors, understand aggregate usage, protect our rights, and maintain the service.
• Legal obligations: to comply with applicable laws, valid legal requests, regulatory requirements, accounting rules, or security obligations.
• Protection of rights and safety: where necessary to protect users, the Site, our service providers, or the public from harm, fraud, abuse, or security threats.

Where consent is the legal basis, you may withdraw consent at any time using the available privacy settings or by contacting us. Withdrawal does not affect processing that occurred before withdrawal.

How We Share and Disclose Information

We do not sell your chat messages. We do not rent your personal information. We share information only as needed to operate, secure, measure, support, improve, advertise, or legally protect the Site.

• AI model, API, and technical delivery providers: We may share prompts, responses, and technical data with providers that help generate AI responses, maintain uptime, route requests, prevent abuse, and troubleshoot errors.
• Google services: We may use Google AdSense, Google Analytics, and related Google technologies for advertising, ad measurement, fraud prevention, analytics, and site usage measurement.
• Cloudflare and security providers: We may share technical and security data with Cloudflare and similar providers for content delivery, security, bot protection, rate limiting, caching, performance, and abuse prevention.
• Hosting, infrastructure, and maintenance providers: We may use service providers to host the website, store limited operational data, deliver pages, monitor errors, and maintain the service.
• Email and contact form providers: If you contact us, your message may be processed by email, form, hosting, or support tools used to receive and respond to inquiries.
• Consent management providers: Consent choices and related technical signals may be processed by tools that help record and manage privacy preferences.
• Public content: If you post comments or public feedback, that content may be visible to other visitors.
• Legal and safety reasons: We may disclose information if required by law, court order, legal process, regulatory request, or where necessary to protect rights, safety, security, users, our service providers, or the public.
• Business transfers: If the Site is involved in a merger, acquisition, restructuring, sale of assets, or similar transaction, limited information may be transferred as part of that transaction, subject to this Policy or a policy with equivalent protections.

Sale, Sharing, and Targeted Advertising

We do not sell personal information for money. We also do not sell your chat messages.

However, some privacy laws define “sale,” “sharing,” “targeted advertising,” or “cross-context behavioral advertising” broadly. Depending on your location, our use of advertising cookies, Google AdSense, ad measurement tools, or similar technologies may be considered “sharing” or “targeted advertising,” even if we do not receive money in exchange for your personal information.

You can opt out of personalized advertising or similar processing by using our cookie choices where available, using Google Ads Settings, blocking advertising cookies in your browser, using industry opt-out tools, or contacting us at info@chat-deep.ai.

Do Not Sell or Share My Personal Information: To make a request, use the available cookie or privacy settings on the Site where available, or contact us at info@chat-deep.ai with the subject line “Do Not Sell or Share Request.”

Data Retention

We keep personal information only for as long as reasonably necessary for the purposes described in this Policy, unless a longer period is required or permitted by law.

• Chat data: We do not maintain permanent Chat-Deep.ai server-side chat history for normal browser chat use. Temporary processing may occur to generate responses, maintain reliability, troubleshoot errors, and prevent abuse. Local browser history may remain on your device until you delete it.
• Contact messages: Contact form submissions and email correspondence are normally kept for up to 24 months, unless a longer period is needed for security, legal, dispute, administrative, or record-keeping reasons.
• Comments: Public comments may remain visible until removed by us or upon a valid deletion request where applicable.
• Analytics data: Analytics data is retained according to our Google Analytics settings and Google’s retention controls. We generally use analytics reports in aggregated or pseudonymous form.
• Advertising data: Advertising cookies and related data are retained according to Google’s and advertising partners’ policies, browser settings, consent choices, and applicable law.
• Security logs: Security and technical logs are normally retained for a limited period, unless needed for abuse prevention, troubleshooting, fraud prevention, legal compliance, or security investigations.
• Consent records: Consent and privacy preference records may be retained as long as needed to manage choices, demonstrate compliance, and meet legal or Google policy requirements.

Your Privacy Rights and Choices

Depending on your location, you may have rights over your personal information. These rights may include the right to access, know, correct, delete, restrict, object, opt out, withdraw consent, request portability, appeal a decision, or limit certain uses of sensitive personal information.

EEA, United Kingdom, and Switzerland

If you are located in the European Economic Area, the United Kingdom, Switzerland, or another jurisdiction with similar data protection laws, you may have the following rights, subject to legal limits:

• Access: request a copy of personal data we hold about you.
• Correction: request correction of inaccurate or incomplete information.
• Deletion: request deletion of personal data where applicable.
• Restriction: request that we limit certain processing.
• Objection: object to certain processing based on legitimate interests.
• Portability: request certain data in a portable format where applicable.
• Withdraw consent: withdraw consent where processing is based on consent.
• Complaint: lodge a complaint with a data protection authority if you believe your rights have been violated.

California and Other U.S. State Privacy Rights

If you are a resident of California or another U.S. state with applicable consumer privacy laws, you may have rights to know, access, delete, correct, opt out of sale or sharing, opt out of targeted advertising, limit certain uses of sensitive personal information, and not be discriminated against for exercising your rights.

We do not sell personal information for money. Certain advertising or analytics technologies may be considered sharing, targeted advertising, or cross-context behavioral advertising under some laws. You may opt out using available cookie settings, Google Ads Settings, browser controls, valid opt-out preference signals where required and supported, or by contacting us.

Brazil and Other Global Privacy Rights

If you are located in Brazil or another country with privacy laws that grant rights over personal data, you may have rights to confirm processing, access data, correct data, delete data, anonymize or block unnecessary data, request portability, withdraw consent, or obtain information about sharing, subject to applicable legal limits.

How to Exercise Your Rights

To exercise privacy rights, contact us at: info@chat-deep.ai.

Please include enough information for us to understand and respond to your request. We may need to verify your identity before fulfilling certain requests, especially if the request involves personal information, deletion, access, or account-related data. Because Chat-Deep.ai does not require user accounts for normal chat use, we may have limited ability to identify or locate data unless you provide enough details.

We will respond within the timeframe required by applicable law. If we deny a request in whole or in part, we will explain the reason where required and provide appeal instructions if applicable.

Sensitive Personal Information

We do not intentionally request sensitive personal information through the normal chat feature. Please do not submit sensitive data unless you fully understand the risks and it is strictly necessary for your own use.

Sensitive information may include passwords, API keys, payment details, government IDs, precise location, health information, financial account information, biometric data, confidential business information, private customer data, children’s data, legal documents, or highly personal messages.

If you submit sensitive information into the chat or a contact form, it may be processed by the systems and providers described in this Policy. We may delete or restrict such data where appropriate or where required by law.

International Data Transfers

Chat-Deep.ai may be accessed by users around the world. We and our service providers may process information in countries different from yours, including the United States and other jurisdictions where our hosting, security, analytics, advertising, AI model, API, or technical providers operate.

These countries may have data protection laws that differ from those in your location. Where required, we rely on appropriate safeguards such as contractual protections, standard contractual clauses, data processing terms, adequacy frameworks, provider privacy commitments, consent, or other lawful transfer mechanisms.

By using the Site or submitting information to us, you understand that information may be processed in countries outside your location as needed to operate and secure the service.

Security Measures

We use reasonable technical and organizational measures designed to protect information processed through the Site. These measures may include HTTPS encryption, access controls, security monitoring, abuse prevention, rate limiting, Cloudflare protection, software updates, and limited data retention.

Because the normal chat feature does not require account registration and because we do not maintain permanent server-side chat history for normal use, our design reduces the amount of personal information stored by Chat-Deep.ai.

However, no website, online service, AI system, or internet transmission is completely secure. You are responsible for avoiding sensitive submissions, protecting your own devices, clearing local browser history where needed, and using official DeepSeek resources for official account, billing, login, API, and support matters.

If you believe you have found a security issue, please contact us at info@chat-deep.ai.

Third-Party Links and Official Resources

Chat-Deep.ai may link to third-party websites, official DeepSeek resources, Google services, Cloudflare resources, app stores, developer platforms, documentation pages, or other external websites.

We are not responsible for the privacy practices, security practices, terms, content, or availability of third-party websites. When you leave Chat-Deep.ai, your use of the external website is governed by that website’s own privacy policy and terms.

Children’s Privacy

Chat-Deep.ai is not directed to children under 13, and in some jurisdictions it may not be directed to children under a higher age threshold, such as 16. We do not knowingly collect personal information from children.

If you are a parent or guardian and believe that a child has provided personal information to us, please contact us at info@chat-deep.ai. We will take reasonable steps to delete the information where required.

Minors should use AI tools only with appropriate supervision and should not submit sensitive personal information.

Automated Decisions and AI Outputs

The AI chat feature generates responses automatically based on your prompts. These responses are for informational and productivity purposes only and should be reviewed carefully.

We do not use the AI chat feature to make legal, financial, employment, credit, housing, healthcare, insurance, or similarly significant decisions about you.

AI outputs may be inaccurate, incomplete, outdated, biased, or unsuitable for your specific situation. Do not rely on AI outputs for legal, medical, financial, safety-critical, or emergency decisions without professional verification.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our services, technologies, providers, legal obligations, advertising setup, analytics setup, AI model routing, consent tools, or privacy practices.

When we update this Policy, we will revise the “Last Updated” date above. For material changes, we may provide additional notice where appropriate, such as a banner, notice on the Site, or updated consent prompt.

Your continued use of Chat-Deep.ai after an updated Policy is posted means you accept the updated Policy to the extent permitted by law.
