Privacy Policy - Chat-Deep.ai

This Privacy Policy explains how Chat-Deep.ai handles information when you read our articles, use our browser chat, contact us, or post a comment. It covers chat processing, saved conversations, service providers, cookies, advertising, retention, and your privacy choices.

Chat-Deep.ai is published and operated by Thinkly For Digital Business, an Egypt-based company serving an international audience. In this policy, “Chat-Deep.ai,” “we,” “us,” and “our” refer to that publisher and operator. This policy applies to this website and its own chat application. Our Terms of Service and Cookie Policy provide related information.

Effective date: July 14, 2026 · Last updated: October 11, 2026

About this update: This version clarifies the difference between local chat history and information sent to DeepSeek, updates the description of our chat and editorial examples, and clarifies retention, privacy choices, and international transfers. It does not announce a change to the chat’s technical implementation.

1. Independent Website and No Affiliation

Chat-Deep.ai is an independent publication about DeepSeek’s models, apps, and API. We are not owned, operated, endorsed, sponsored by, or affiliated with DeepSeek or High-Flyer. Our About page explains who publishes the site and how our articles are prepared.

Our browser chat is our own application built on the DeepSeek API. It is separate from DeepSeek’s official chat and app. We do not require a Chat-Deep.ai account or ask for your official DeepSeek password, API key, billing details, or payment credentials. Do not include those details in a message. DeepSeek’s own services have their own privacy policies and terms.

2. Data Controller and Contact Details

For personal information whose purposes and means of processing are determined by this website, the data controller is Thinkly For Digital Business. You can contact us at info@chat-deep.ai or through our contact form. Use “Privacy” in the subject line and describe the feature or information involved.

Service providers may act as processors, independent controllers, or other recipients, depending on the service, the contractual arrangement, and applicable law. A provider’s privacy policy describes its role; it does not replace our responsibility to explain this website’s handling of information.

3. The Browser Chat: What Happens When You Send a Message

The chat is available on our dedicated chat page. When you send a message, your browser sends the text, any attached images, and a limited amount of recent conversation context to our application infrastructure. Our server passes the request to DeepSeek’s API and returns the generated answer to your browser as it arrives. This processing happens whether local saving is on or off.

Fast and Pro are the chat’s answer modes. “Ask about DeepSeek” adds instructions and reference information to help answer questions about DeepSeek. “Compare Fast vs Pro” sends your input to both modes to return two answers, so one use of that comparison produces two requests. The underlying data flow is the same. The chat does not browse the live web or open a link just because you paste it.

Temporary processing and server-side history. Our application does not write your messages, images, or answers to a server-side conversation store. Uploaded images are validated and handled in server memory rather than written to disk. Pro-mode reasoning text is not sent to your browser. This describes our application’s handling; hosting, security, and diagnostic records and DeepSeek’s own processing are separate. It is not a zero-retention guarantee.

Fair-use counters. We keep short-lived counters keyed to a one-way hash of your connection IP address and a first-party visitor cookie. They enforce daily and shorter-term usage limits and help control the site’s API spending. The current chat allowance is 50 messages a day, including up to 10 Pro messages; the chat page shows the current limits. Minute and hour counters expire with their windows, and the daily counter resets at midnight UTC. These counters do not contain message text.

Saved conversations on your device. When local history is on, your browser saves prompts, answers, attached images, titles, and timestamps in its own storage. Saved images are resized and their photo metadata is removed. This is a local copy, with no account-based synchronization to another browser or device.

Local saving is separate from sending a request. Content from the conversation, including recent messages used as context, is transmitted through our application to DeepSeek when you send a message. Keeping the saved copy on your device does not keep submitted content on that device.

Privacy Mode and deletion. Privacy Mode stops new local saves and removes the current conversation from saved history. That conversation remains visible until you leave it. Other saved conversations are not deleted. Use Delete for an individual conversation or Clear all for saved conversations in this browser. Export anything you need first. Clearing this site’s data through your browser settings also removes local history and may reset preferences and cookie choices.

Local history has no time-based expiry; it remains until you delete it or remove the browser’s site data. We cannot recover a copy held only on your device. Privacy Mode and local deletion do not prevent API processing, make the chat anonymous, or erase information already retained by a provider. The website FAQ explains the history and export controls.

Bot protection. Before each message is accepted, Cloudflare Turnstile runs an invisible check in your browser and our server verifies its token against your connection IP, this site’s hostname and the requested action. Turnstile is described in Section 12.

Voice input. Where supported, the dictation control uses your browser or device’s speech-recognition feature to turn speech into text. That feature may use its own provider’s services under its own privacy terms; it should not be assumed to work entirely offline. The resulting text is sent through our chat when you choose to send it.

Do not submit sensitive data. Do not paste passwords, API keys, payment details, confidential business information, health records or other sensitive information into the chat. AI output can be wrong, incomplete or outdated; verify anything important.

4. DeepSeek API Processing and Privacy Scope

DeepSeek receives the message content, attached images, recent context, selected mode, and technical instructions needed to generate an answer. We do not send your contact-form details or the chat’s visitor cookie as identity fields in that request. If you type a name, email address, or other personal information into a message, however, it becomes part of the content you are sending. Our server-side API credentials are not exposed to your browser.

DeepSeek is established in China. API content may be processed, stored, or cached by DeepSeek under the applicable service terms and legal obligations. Its Privacy Policy explicitly excludes the processing rules of downstream applications from that policy’s scope. Its Open Platform Terms require developers of those applications to explain their own processing and handle end-user rights requests. This policy describes our application.

DeepSeek’s context-caching documentation says disk caching is enabled by default and that unused cache is normally cleared within a few hours to a few days. That is a description of the cache, not a deadline for deleting all provider records. We do not promise zero retention, immediate deletion by DeepSeek, or an exclusion from every provider-side service-improvement process.

5. Information We Collect and Process

Chat content: the text and images you send, and the answers returned, processed as described in Sections 3 and 4.
Usage counters: hashed connection IP, first-party visitor cookie, message counts and timestamps for limit enforcement and cost control.
Consent and region signals: a signed first-party cookie and a browser storage flag recording that you accepted the chat’s notice (visitors in the EEA, the UK and Switzerland); the consent choices you make in the Google consent dialog; and the two-letter country code that Cloudflare attaches to each request, which we use only to decide whether to show the consent dialog and how to load advertising.
Technical and security data: IP address, user agent, requested URLs, referrer, timestamps, response codes and error details in server, cache, firewall and application logs.
Contact and comments: the name, email address and message you submit through the contact form or when posting a comment, with the IP address recorded at submission.
Analytics and advertising data: cookies, identifiers and events collected by Google Analytics and Google AdSense as described in Section 10.

You do not need an account to read the site or use the chat. We do not ask for sensitive categories of personal information. If you include them in a message or upload, they are still part of the content processed by the application and providers. Please leave them out rather than relying on Privacy Mode to protect them.

6. How We Use Information

Reading an article does not send a chat request to DeepSeek. Ordinary website use can still involve hosting, security, analytics, advertising, and consent services. Contact messages and public comments are separate from browser-chat conversations.

To operate the site and the browser chat, including generating answers through the DeepSeek API.
To enforce fair-use limits, prevent abuse and automated traffic, and keep our API spending within budget.
To show and measure advertising and to understand how public pages are used.
To secure, monitor, debug and improve the site and its infrastructure.
To respond to contact requests, moderate comments and handle legal requests.
To comply with legal obligations and to establish, exercise or defend legal claims.

7. Legal Bases for Processing

Where the GDPR, UK GDPR, or similar laws apply, the processing purposes and bases described by this website are:

Providing a requested service: processing needed to provide the chat or respond to your request, where performance of a contract or steps at your request is the applicable basis.
Legitimate interests: securing and operating the site, preventing abuse, enforcing usage limits, managing service costs, and responding to communications, subject to the relevant balancing of those interests and your rights.
Consent: non-essential cookies and analytics or advertising activities where consent is required. The chat’s processing notice and the website’s cookie choices serve different purposes.
Legal obligations: processing needed to meet an applicable legal requirement.

You can ask us which basis applies to a specific use of your information. The international-transfer arrangements discussed in Section 13 are a separate issue; listing a processing basis here does not establish that a particular transfer safeguard is in place. Sections 10 and 15 explain consent choices and privacy requests.

8. Data Retention

Local history, temporary chat processing, usage counters, and provider records are different categories. Deleting one does not necessarily delete the others.

Chat content in our application: messages and images are processed for the request, without a server-side conversation store. This does not set a retention period for infrastructure records or DeepSeek’s processing.
Usage counters: minute and hour counters expire with their respective windows, the daily counter resets at midnight UTC, and the monthly spending total resets at the beginning of the calendar month.
Visitor and chat-notice cookies: the configured duration of the site’s visitor cookie and chat-notice cookie has not been verified, so we do not state a fixed lifetime. You can remove them through your browser’s site-data controls. The Cookie Policy explains their purposes, browser storage, and separate consent-management records.
Local conversation history: saved in this browser until you delete it or clear the site’s browser data.
Hosting, cache, security, and diagnostic records: the duration depends on the type of record, the relevant service’s settings, and operational or legal needs such as investigating abuse or an incident. We do not state a verified fixed deletion period for these records.
Contact messages and comments: retained to respond, manage the discussion or correction, maintain relevant records, and handle associated disputes or legal obligations. Contact us about deletion of information relating to your message or comment.
Google Analytics and advertising data: retention depends on the relevant product, the site’s configured settings, your choices, and Google’s applicable terms.
DeepSeek records: subject to the provider’s applicable processing, retention, and caching practices. Section 4 explains the scope of its published caching information.

To ask about retention of a particular record, email us with the feature and approximate date involved. Do not send a private conversation or credential as proof. We have not verified one deletion schedule covering every provider and category of record.

9. How We Disclose Information

We disclose submitted chat content to DeepSeek to generate answers. Hosting, delivery, security, consent, analytics, advertising, and mail providers also process information for the services described in this policy. We may disclose information to professional advisers, to authorities when required by law, or in connection with a merger, acquisition, or reorganization.

Where you post a comment and it is published, its displayed author name and content are visible to other readers. Do not include private contact details or confidential material in a public comment. Contact-form messages use a separate channel.

We do not sell personal information for money. Advertising technologies can nevertheless involve sharing or targeted advertising under some laws; Section 11 explains the distinction and your choices.

We use cookies, local storage and similar technologies for essential functions (the visitor cookie, the consent cookie, the chat notice flag, cache and security), for analytics (Google Analytics) and for advertising (Google AdSense). Google and its certified vendors may use cookies and identifiers to serve and measure ads. The Cookie Policy lists the cookies in use.

For visitors in the EEA, UK, and Switzerland, the site provides a Google-certified consent dialog for relevant advertising and analytics choices, and a separate notice about DeepSeek processing before the first chat message can be sent. These are different controls: accepting a chat notice is not the same as agreeing to personalized advertising.

The site uses the country code supplied by Cloudflare to select the consent experience. Where the consent dialog is provided, use “Privacy and cookie settings” in the footer to reopen it and change or withdraw the relevant choices. In other locations, that link may open our Cookie Policy instead. If you cannot access a choice you need, contact us. A different interface in your location does not remove any rights you have under applicable law.

You can also manage or delete cookies in your browser settings, use Google My Ad Center to manage ad personalization, or use Google’s Analytics opt-out browser add-on where supported. Google explains these options and the information it receives in How Google uses information from sites or apps that use its services. Blocking essential technologies may prevent parts of the site or chat from working.

Cookie choices, local chat saving, and submitted messages are separate. Privacy Mode does not disable advertising or Analytics. Changing a cookie choice does not undo a message already sent, and deleting browser data does not delete records held by a provider. To stop sending new chat content, stop using the chat; contact us with a request about information already processed.

We do not sell personal information for money. Under some US state laws, allowing advertising technologies to use information for personalized ads may qualify as “sharing” or “targeted advertising” even without a monetary sale.

Use the available consent controls to decline relevant advertising choices, and use your browser settings or Google’s ad controls where appropriate. You can also send an opt-out request through our contact form or privacy email. Rights depend on the law that applies to you; we will not discriminate against you for exercising them. Requests and any legally applicable opt-out preference signals must be handled in accordance with that law.

12. Hosting, Infrastructure and Security Providers

The website and chat application run on US-hosted infrastructure. Cloudflare provides traffic delivery, caching, firewall and DDoS protection, rate limiting, TLS, and the Turnstile bot check. Those services can process IP addresses, request metadata, browser or device signals, and timestamps. LiteSpeed supports web serving and caching. Google supplies consent, Analytics, and advertising services; DeepSeek processes chat requests; hosting and mail services handle email and contact-form delivery.

These providers have their own service terms and data-handling documentation. Their public policies do not, by themselves, establish which account settings or additional agreements apply to this website. A hashed IP address in a chat usage counter also does not mean raw connection information is absent from every hosting or security record.

13. International Data Transfers

Using this website can involve processing outside your country: in the United States for hosting, across service providers’ international infrastructure, and in China or other locations involved in DeepSeek’s processing. Chat content is sent to DeepSeek when you choose to send a message; you can read the site without sending a chat request.

We have not verified which contractual transfer safeguards apply to every provider relationship. This policy therefore does not confirm that Standard Contractual Clauses, a UK Addendum, or a particular transfer framework covers a specific transfer from this website. A provider offering such arrangements does not establish that they have been put in place for our account.

If you need information about a particular transfer and its safeguards, contact us before submitting information subject to confidentiality or location requirements. Acceptance of the chat notice is not presented here as proof that every international-transfer requirement has been met. The chat does not provide a promise that data stays in your country.

14. Security

Our safeguards include HTTPS/TLS, access restrictions and updates, Cloudflare traffic and bot protection, server-side API credentials, short-lived usage counters without message text, and temporary in-memory image handling. They address different risks and do not make submitted information risk-free. Our Security page explains these measures, their limits, and how to report a concern safely.

No system or transmission method is completely secure. If you believe information has been exposed, contact us promptly without resending the private material. If the issue involves a disclosed password or API key, change or revoke it through the responsible service; removing a local chat copy does not invalidate the credential.

15. Your Privacy Rights

Depending on your location and the law that applies, you may have rights to access, correct, delete, or receive a copy of personal information; restrict or object to processing; withdraw consent; or opt out of relevant sharing or targeted advertising. You may also complain to a competent data-protection authority. These rights can have conditions and exceptions.

Your right to object: where applicable, you can object to processing based on legitimate interests and to direct marketing. Tell us which processing your objection concerns. Where processing relies on consent, you can withdraw that consent; withdrawal does not make earlier lawful processing unlawful.

To make a request, use our contact form or email info@chat-deep.ai with “Privacy” in the subject. Describe the request and the feature involved. We may need proportionate information to verify that a request concerns your data. Do not send identity documents, private conversations, or credentials unless we have explained why particular information is necessary and how to provide it appropriately.

We handle requests about our application and website. Where a request requires cooperation from DeepSeek or another provider, that may require coordination with the provider. The DeepSeek Open Platform Terms describe the developer’s responsibility to respond to end-user rights requests and the possibility of provider support. We do not promise that we can retrieve or erase every provider record.

A saved conversation held only in your browser must be managed on that device; we cannot recover it for you. That limit does not prevent you from asking about other information processed in connection with your use of the service. If you mean an account or activity on DeepSeek’s official service, contact that service through its own privacy channels. We will not discriminate against you for exercising applicable rights.

16. Children and Teenagers

This website is not directed to children under 16. Our browser chat is intended for adults aged 18 and over. These describe this website’s audience and chat restriction; eligibility to use other parts of the service is addressed in our Terms of Service.

We do not knowingly collect personal information from children. If you believe a child has provided it to us, contact us so the matter can be addressed and relevant information deleted where appropriate. Do not include the child’s private conversation or sensitive documents in the initial report.

17. Sensitive Information and Other People’s Data

Do not submit sensitive personal information about yourself or anyone else through the chat, the contact form or comments. If you include information about other people, you are responsible for having the right to share it.

18. AI Output and Examples

Chat answers are generated automatically and can be inaccurate, incomplete, outdated, or biased. They are separate from our articles, which receive human review of their information, sources, and examples before publication.

Our current articles rely on official or original sources. An illustrative prompt, fictional example, calculation, or documented procedure is not automatically a live product test. When an actual test is included, its date, method, conditions, and limitations should be identified. Published examples should not be interpreted as a feed of visitors’ private chat conversations. Our Editorial Policy explains how examples, sources, AI assistance, and human review are handled.

19. Third-Party Links and Services

Our pages link to DeepSeek’s official website, chat, apps, developer platform, documentation, status page and privacy policy, and to other third-party sites. Those services have their own privacy practices, and this Policy does not apply to them.

20. Changes to This Privacy Policy

We update this policy when our practices change or when its descriptions need correction or clarification. The “Last updated” date identifies the version of the notice, and the update note explains the material changes made to it. An editorial revision is not, by itself, evidence of a new technical safeguard or a completed security or compliance audit.

Where a change requires a further notice or a new consent choice, that requirement is separate from reading the updated policy. Continued browsing should not be treated as a substitute for consent where consent is required.

21. How to Contact Us

For privacy questions or requests about Chat-Deep.ai, email info@chat-deep.ai or use the contact form. Put “Privacy” in the subject and identify the relevant page or feature, the approximate date, and what you want us to clarify or do.

For a local-history problem, first check the controls on the device where the conversation was saved. For information already submitted through the site, send us a clear description of your concern without repeating the sensitive material. That gives us a useful starting point for responding to your request.
