Chat-Deep.ai is published and operated by Thinkly For Digital Business, an Egypt-based company serving an international audience. We are an independent publication and operate our own browser chat using the DeepSeek API. We are not owned, operated, endorsed, sponsored by, or affiliated with DeepSeek or High-Flyer. Our About page explains our role.

What happens when you send a chat message
When you send a message, its text, any attached images, and recent conversation context pass through Chat-Deep.ai’s application infrastructure to the DeepSeek API. DeepSeek processes that material to generate an answer, which our application returns to your browser. This happens whether local history is on or off.
The chat is free to use without a Chat-Deep.ai account, subject to fair-use limits. You do not need to give us an official DeepSeek password, API key, or payment details. The application uses the site’s server-side API credentials. We cannot access or change your official DeepSeek account, billing, keys, or support cases.
Our Privacy Policy describes the application’s handling of messages and images: temporary processing in server memory, with no server-side conversation store and no uploaded images written to disk. Hosting, security, diagnostic, and abuse-prevention records are separate, as is processing by DeepSeek. Not keeping a conversation history on our server does not mean that no service processes or retains 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 comments have their own processing described in the Privacy Policy.
Local history and Privacy Mode
Local history is the saved copy of a conversation in this browser’s storage on your device. It can contain prompts, answers, attached images, titles, and timestamps. The Privacy Policy describes saved images as resized with photo metadata removed. There is no account-based history that automatically synchronizes these conversations to another browser or device.
Local saving and sending a message are different operations. Keeping the saved history on your device does not keep a message you submit on that device. The message, attachments, and relevant conversation context still travel through our application to DeepSeek when you send a request.
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. Privacy Mode does not stop API transmission, hide your network information from the services involved, or provide anonymous, offline, or zero-retention chat.
Saved history has no time-based expiry in our chat: it remains until you delete it. Use Delete for an individual conversation or Clear all for saved conversations in this browser. Export anything you need to keep first. Clearing this site’s data through your browser settings also removes local history and may reset preferences and cookie choices.
We cannot recover conversations stored only on your device. Deleting that local copy does not delete information already processed or retained by DeepSeek or another provider. The website FAQ explains history, export, and common chat problems; the Cookie Policy covers browser storage and cookie choices.
Security measures and their limits
The safeguards described in our Privacy Policy include:
- Connection protection: HTTPS/TLS for supported connections to the website.
- Access and maintenance: restricted administrative access and updates to the website and its supporting components.
- Traffic and abuse controls: Cloudflare firewall and rate-limiting services, plus Turnstile bot checks for the chat.
- Application handling: server-side API credentials, temporary in-memory handling of uploaded images, and no server-side conversation store.
- Usage controls and technical records: short-lived chat counters keyed to a one-way hash of your IP address and a first-party visitor cookie, alongside records used for security, reliability, and diagnosis. The chat counters contain no message text.
Each measure has a specific purpose. HTTPS protects data in transit between supported endpoints; it does not prevent the receiving service from processing it. A hashed IP address in a usage counter does not mean raw connection information is absent from every hosting or security record. Bot checks and rate limits help control abuse but do not make submitted information risk-free.
We work to reduce foreseeable risks, but no transmission method, software platform, hosting environment, API, or storage mechanism is completely secure. Chat-Deep.ai does not guarantee uninterrupted operation, immunity from vulnerabilities, or absolute protection against unauthorized access, loss, misuse, or alteration. Additional service limitations appear in our Disclaimer and Terms of Service.
Service providers, caching, and international processing
Our site depends on hosting and delivery infrastructure, security and consent services, email delivery, and the DeepSeek API for chat answers. The Privacy Policy identifies Cloudflare, LiteSpeed, Google services, DeepSeek, and the roles of our hosting and mail services. Depending on the feature used, providers may process IP addresses, request metadata, browser or device details, timestamps, and other information needed to operate their services.
We use Google Analytics and Google AdSense. Cookies and related technologies can process browsing, advertising, and interaction data. Our Cookie Policy and the consent choices available on the site explain these separately from chat history. Turning off local chat saving does not turn off every other form of website processing.
The browser chat is not a zero-retention service. DeepSeek’s context-caching documentation says caching is enabled by default and that unused cache is usually cleared within a few hours to a few days. This describes the cache, not a deletion deadline for all provider records. We do not promise that submitted content is excluded from every provider-side security, retention, or service-improvement process.
Using the chat can involve international processing, including in China, where DeepSeek is established. Our Privacy Policy describes US hosting and the involvement of providers’ global infrastructure. We do not guarantee that submitted data stays in your country.
DeepSeek’s Privacy Policy states that the downstream applications built on its platform are outside that policy’s coverage. Its Open Platform Terms require developers to disclose the processing rules for their own applications. Our Privacy Policy therefore explains Chat-Deep.ai’s data handling; DeepSeek’s consumer policy alone is not a retention or residency guarantee for this chat.
If your work requires particular confidentiality, retention, residency, audit, or compliance guarantees, use a service and arrangement approved by your organization. An article on this website, a free chat interface, or Privacy Mode does not supply those guarantees.
What to keep out of submissions
Do not send information you cannot safely share through the chat, contact form, comments, or a security report. This includes:
- Passwords, verification or recovery codes, API keys, access tokens, and private keys.
- Payment-card numbers, banking credentials, and financial account details.
- Confidential business information, trade secrets, restricted internal documents, and private source code.
- Identity documents, sensitive personal information, and private information about another person.
- Protected health, legal, employment, education, or financial records.
- Material covered by contractual, professional, regulatory, or data-residency restrictions.
Use a redacted or invented example when it can explain your question. For instance, a report about an error usually needs the page, the visible error, and the steps that led to it—not the private conversation that happened to be open. Check screenshots and logs for names, keys, account details, and other sensitive material before sharing them.
Protect your device and check important answers
Keep your browser, operating system, and security software updated. Avoid entering private information on an untrusted or shared device. A conversation saved in your browser is not an access-control system; consider who else can use that browser or device. If you export a conversation, take care of the exported copy as well as the history shown in the chat.
Chat answers are generated automatically. They are not the human-reviewed articles described in our Editorial Policy. Check important facts, calculations, links, and code before relying on them. Do not use the service for emergencies or as the sole basis for medical, legal, financial, employment, access-control, or other high-impact decisions.
Follow our Terms of Service. Do not bypass protections or usage limits, disrupt the website, or attempt to access information or systems without permission. If you need an official DeepSeek service, use the destinations identified in our FAQ. Chat-Deep.ai cannot resolve an incident inside an official DeepSeek account.
If you think information has been exposed
Stop sharing the affected information and contact the organization responsible for the account, system, or data involved. If a password or API key has been disclosed, change or revoke it through that service’s official controls; deleting a chat message does not invalidate a credential. For work-related data, follow your organization’s incident-reporting process.
If the concern involves Chat-Deep.ai, contact us promptly with a description of what happened and the affected feature. Do not resend the secret or private material as proof. A privacy request about information handled by this website should use “Privacy” in the subject line; our Privacy Policy explains that request process. Reporting a concern does not mean we can recover local history or erase records held by another provider.
Report a security issue affecting Chat-Deep.ai
Email info@chat-deep.ai with “Security report” in the subject line. A useful report includes the affected URL or feature, what you observed, the approximate time, and the steps that led to the issue. Where relevant, include your browser and operating system, along with screenshots or evidence that can be shared safely.
Describe only what you observed and remove credentials, personal data, and private conversation contents. If an issue exposes another person’s information, do not investigate further, download it, or include it in your report. Explain where and how it appeared without reproducing that information.
Reporting a suspected issue does not authorize security testing. Do not access or alter data that does not belong to you, disrupt service availability, perform social engineering, deploy malware, conduct denial-of-service testing, or use automated testing that could harm the website or its users. Allow reasonable time for investigation before making an issue public. Our Terms require prior written permission from the system owner to probe, scan, test, or exploit a vulnerability.
For an ordinary website error, an article correction, or help using the chat, use our Contact page. Include the page and the specific problem so your message can be understood without access to your private conversation.
How we handle incidents and updates
If we become aware of a suspected security incident affecting systems within our control, we may investigate, limit access, preserve relevant technical records, apply corrective measures, and notify affected parties or authorities where required by applicable law. The actions taken will depend on the nature and scope of the incident.
We may update this page when our architecture, providers, safeguards, or legal obligations change. The review date records a review of this page; it is not a claim that a security audit or penetration test took place. Material changes to personal-information handling will also be reflected in the Privacy Policy where applicable.
Before sending anything through the chat or a contact channel, decide whether it is suitable to share with the services involved. Use the local-history controls for the copies on your device, and contact us if a security or privacy concern needs attention. A clear, redacted description is the most useful starting point.
