Security

Last reviewed: September 5, 2026

Chat-Deep.ai is an independent publication. It is not operated, endorsed, sponsored by, or affiliated with DeepSeek. This page explains the security practices and limitations that apply when you use our website, together with historical information about the retired browser chat.

Publication transition — September 5, 2026. Our browser chat was retired on September 5, 2026. The site now focuses on guides, comparisons and independent research. This change does not automatically erase old browser history, logs or information already processed by an API provider.

Security at a Glance

  • The current site publishes guides, comparisons and research; it does not provide a chat interface.
  • HTTPS protects supported connections to the website.
  • Hosting, delivery, security, consent, analytics and advertising providers may still process technical information as described in our Privacy Policy.
  • Conversation history saved by the former chat may remain in your browser until its site data is removed.
  • No website or online service can guarantee absolute security.

How the Former Chat Processed Data

Before September 5, 2026, a message submitted through the Chat-Deep.ai browser chat sent the prompt and relevant conversation context through Chat-Deep.ai application infrastructure to the DeepSeek API. DeepSeek processed that material to generate a response. The standard chat did not require a Chat-Deep.ai account; API credentials were handled on the server side and were not intentionally exposed in the browser interface.

Transmission was required even when Privacy Mode was enabled. Privacy Mode controlled local history; it was not an anonymous, offline or zero-retention setting.

The former chat did not provide permanent, account-linked server chat history for standard use. Requests were processed temporarily, and limited technical records could be created for security, reliability, error diagnosis and abuse prevention. Retiring the interface does not prove that those records or records held by providers have been erased.

Former API Processing: Caching and Provider Retention

DeepSeek’s context-caching documentation referenced by the former chat described caching as enabled by default and best effort. Reusable prompt prefixes could be cached for hours to days. Cache availability and duration were controlled by DeepSeek. See its official context-caching documentation for its current description; cache expiry is not proof that every other provider record has been deleted.

The former chat was not a zero-retention service. We do not promise that previously submitted content was categorically excluded from all provider-side security, retention or service-improvement processes. Provider obligations and applicable privacy rights remain relevant to past processing.

Former Chat International Processing and Data Residency

The former chat used the DeepSeek API operated by Hangzhou DeepSeek Artificial Intelligence Co., Ltd. in China. Transmitting prompts and relevant context could involve an international transfer of personal information to China. Chat-Deep.ai did not guarantee that data submitted through that integration stayed in the user’s country.

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. It therefore should not be read as a universal API-retention or data-residency guarantee for past Chat-Deep.ai requests. See our Privacy Policy for the fuller explanation of international transfers and the roles of the services involved.

Data Left by the Former Chat and Privacy Mode

The former chat enabled local history by default and could store up to 50 recent conversations in the browser profile where they were created. It did not apply a time-based expiry. Saved history could be removed individually, displaced by the conversation limit or removed by clearing site data or browser storage. Previously saved data may still remain after the chat is retired.

The former Privacy Mode prevented new local saves and removed only the currently open saved conversation, if one existed. It did not delete every older conversation, hide network information from providers or stop API transmission. The former New Chat control did not erase history. Those interface controls are no longer offered. To remove remaining local history, clear Chat-Deep.ai site data using your browser settings. This permanently removes the local data and may reset cookie choices and other site preferences. It does not delete information already processed or retained by DeepSeek or another provider.

Security Measures

We use technical and operational measures intended to reduce security risk. These measures include:

  • HTTPS encryption for supported connections between your browser and the website;
  • access controls for the website and its supporting systems;
  • technical logging and protective controls intended to identify errors, attacks, and abusive use;
  • software, hosting, delivery, and security services used to operate and protect the website; and
  • review and maintenance of the website and its supporting components.

These measures reduce risk but do not eliminate it. HTTPS protects data in transit between supported endpoints; it does not make submitted information risk-free and does not control how an API provider processes information after receipt.

Infrastructure and Third-Party Services

Operating Chat-Deep.ai requires third-party infrastructure and services. Depending on the request and feature used, these may include our hosting environment, LiteSpeed and QUIC.cloud performance or delivery services, security services, consent-management tools, and email providers. These providers may process technical information such as IP addresses, request metadata, device or browser details, timestamps, security events, and other data needed to provide their services.

Chat-Deep.ai also uses Google Analytics and Google AdSense. These services may use cookies or similar technologies and process browsing, device, advertising, and interaction data. Their operation is explained further in our Privacy Policy and Cookie Policy.

What You Should Not Submit

Do not submit information that you cannot safely share through contact forms, comments or other site submissions. This includes:

  • passwords, API keys, private keys, recovery codes, or authentication tokens;
  • payment card numbers or banking credentials;
  • confidential business information, unpublished source code, or trade secrets;
  • sensitive personal information about yourself or another person;
  • protected health, legal, employment, education, or financial records; or
  • information subject to contractual, professional, regulatory, or data-residency restrictions.

If your organization requires specific retention, residency, confidentiality, audit or compliance guarantees when using an external AI service, assess that provider’s contracts and use an architecture approved by your legal, privacy and security teams. Our guides do not supply those guarantees.

Your Security Responsibilities

  • Keep your browser, operating system, and security software updated.
  • Avoid sending private information from untrusted devices or networks.
  • Remove sensitive details before sending a contact message, comment or security report.
  • Verify AI-generated answers before relying on them or using generated code.
  • Do not use Chat-Deep.ai for emergencies, access-control decisions, or as the sole basis for medical, legal, financial, employment, or other high-impact decisions.
  • Follow our Terms of Service and do not attempt to bypass, disrupt, exploit, or misuse the service.

Security Incident Response

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.

Responsible Security Reporting

If you believe you have found a security vulnerability affecting Chat-Deep.ai, email info@chat-deep.ai with a clear description, the affected URL or feature, reproduction steps, and any supporting evidence that can be shared safely. Do not include personal data, credentials, or data obtained from another user.

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.

No Absolute Security Guarantee

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.

Changes to This Security Page

We may update this page when our architecture, providers, safeguards, or legal obligations change. The “Last reviewed” date at the top identifies the most recent review. Material changes to how personal information is handled will also be reflected in the Privacy Policy where applicable.
