Terms of Service - Chat-Deep.ai

Effective Date: September 5, 2026
Last Verified: September 5, 2026

These Terms of Service (“Terms”) govern your access to and use of Chat-Deep.ai, including its public pages, articles, guides, independent research, comparisons, contact features and informational tools (collectively, the “Service”).

The Service is published and operated by Thinkly For Digital Business, an Egypt-based company (“Thinkly For Digital Business,” “Chat-Deep.ai,” “we,” “us,” or “our”). By accessing or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

Our Privacy Policy, Cookie Policy, and any notices displayed within a feature also apply to your use of the Service.

Publication transition — September 5, 2026. Our browser chat was retired on September 5, 2026. The current Service is an independent publication. References to the former chat below explain past use and remaining data; they do not offer a current chat feature. This update does not erase prior records, remove accrued rights or retrospectively replace terms that applied to an earlier interaction.

1. Independent Website and No Affiliation

Chat-Deep.ai is an independent publication and information resource. It is not the official DeepSeek website, official DeepSeek Chat, official DeepSeek application, official login page, official developer platform, billing portal, or support channel.

The former browser chat used API services provided by Hangzhou DeepSeek Artificial Intelligence Co., Ltd. (“DeepSeek”). That was a technology-provider relationship only. It did not mean that DeepSeek owned, operated, sponsored, authorized, certified, recommended or endorsed Chat-Deep.ai. We remain independent of DeepSeek. Thinkly For Digital Business is not DeepSeek’s agent, partner, representative, reseller, franchisee, or affiliate.

“DeepSeek,” its model names, logos, and related brand features belong to their respective owner. References on this website are used for identification, commentary, documentation, comparison, and interoperability information. No ownership, authorization, or special relationship is claimed.

2. Eligibility and Use by Minors

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 the Service only after your parent or legal guardian has reviewed these Terms and our Privacy Policy and has consented to your use. If that consent cannot lawfully be given, do not use the Service.

A parent or legal guardian who permits a minor to use the Service is responsible for supervising that use and explaining the risks of submitting or publishing personal information online. Separate terms apply when using an external AI service. Minors must not submit passwords, payment details, private credentials, school or medical records, identity documents, precise location, private images, confidential documents, or other sensitive personal information.

If you believe a child has submitted personal information without appropriate authorization, contact info@chat-deep.ai.

3. Former Browser Chat: Historical Processing

Before retirement, a message submitted through the Chat-Deep.ai browser chat sent the prompt to our infrastructure. We transmitted the prompt, relevant previous messages and technical or formatting instructions to the DeepSeek API. DeepSeek processed the content and returned AI-generated output through our infrastructure to the browser.

Normal use of the former browser chat did not require a Chat-Deep.ai account. We did not ask for your official DeepSeek password, DeepSeek API key, DeepSeek payment credentials, or DeepSeek billing information.

DeepSeek and the infrastructure, hosting, security, network, and logging providers involved in the former chat could process submitted information and may retain records of past processing under their applicable terms, settings, contracts, security practices, and legal obligations. That processing could occur outside your country. Retirement does not establish that all past records have been deleted. Read our Privacy Policy for a fuller explanation of the data flow, providers, international transfers, retention limitations, and privacy rights.

DeepSeek’s publicly available Open Platform materials do not state one fixed retention period that applies to every API request made through every downstream application. We therefore do not promise immediate provider-side deletion, universal zero retention, a particular provider-side retention period, or a universal exclusion from provider service-improvement use unless the relevant restriction is confirmed by an applicable API account control or written agreement.

DeepSeek’s API documentation describes provider-side context caching that is enabled by default. Provider processing practices may change. See the official DeepSeek Context Caching documentation and our Privacy Policy for the privacy context relevant to that former feature. Any current use of DeepSeek’s own services is separate and governed by their own terms.

4. Former Privacy Mode and Remaining Local History

When local history was enabled, the former chat could store up to 50 recent conversations in the same browser’s local storage. This was neither an official DeepSeek history nor permanent account-based server chat history maintained by Chat-Deep.ai. Previously saved local data may remain after retirement.

The former interface supported individual history deletion and had no clear-all-history control. Those interface controls are no longer offered. To remove remaining local history, clear Chat-Deep.ai site data in your browser settings. This permanently removes the locally saved data and may reset cookie choices and other preferences. The former New Chat control did not erase saved history. You remain responsible for securing your device and browser, including removing local history from shared, public, school or workplace devices. Clearing site data does not delete information already processed or retained by an external provider.

Privacy Mode in the former chat prevented new local saves and removed the currently open saved conversation, if one existed; it did not delete all older conversations or prevent the prompt and relevant context from being sent through our infrastructure to the DeepSeek API. It was not anonymous, offline or zero-retention mode. Provider processing, context caching, temporary application processing and limited security or diagnostic records could still occur, and retirement does not prove that all past records were erased.

5. Sensitive, Confidential, and Third-Party Information

Do not send sensitive or confidential information through contact forms, comments or other site submissions. In particular, do not enter:

passwords, authentication or recovery codes, API keys, access tokens, private keys, or other credentials;
payment-card information, bank details, billing credentials, or financial account information;
government identifiers, identity documents, medical, tax or insurance records, or biometric information;
trade secrets, export-controlled information, unreleased source code, confidential business plans, privileged communications, or restricted internal documents;
customer, employee, patient, student, or children’s data unless you have a valid legal basis, appropriate authority, and suitable safeguards; or
another person’s personal, confidential, copyrighted, or proprietary information without the required authorization.

You are responsible for determining whether you are legally and contractually permitted to submit content. The former chat’s Privacy Mode did not make sensitive or confidential information suitable for submission.

6. Acceptable Use

You may use the Service only for lawful purposes and in accordance with these Terms. You agree not to:

violate applicable law, a court order, a contractual obligation, or another person’s rights;
use the Service for fraud, phishing, scams, spam, credential theft, impersonation, unauthorized surveillance, illegal data collection, or deceptive conduct;
create, transmit, or distribute malware, ransomware, spyware, destructive code, or operational instructions intended to facilitate unauthorized access or harm;
generate, request, publish, or distribute unlawful, exploitative, abusive, harassing, hateful, defamatory, or sexually exploitative material;
create, request, possess, or distribute child sexual abuse or exploitation material;
promote or provide operational assistance for terrorism, violent extremism, human trafficking, or serious violent wrongdoing;
infringe intellectual-property, privacy, publicity, confidentiality, or other third-party rights;
gain or attempt to gain unauthorized access to an account, server, API endpoint, data, system, or non-public area;
probe, scan, test, or exploit a vulnerability without prior written permission from the system owner;
bypass or evade rate limits, moderation, consent controls, bot protections, access restrictions, geographic controls, or security measures;
use bots, scripts, scraping, crawling, or repeated automated requests in a way that overloads, disrupts, degrades, or imposes an unreasonable burden on the Service or its providers;
reverse engineer, interfere with, damage, disable, or disrupt the Service or its infrastructure, except where a restriction is prohibited by applicable law;
use an AI output as the sole basis for an unlawful or prohibited high-impact decision about another person;
misrepresent AI-generated material as verified human-created material where disclosure is legally or contractually required;
misrepresent Chat-Deep.ai as an official DeepSeek service or misrepresent your relationship with Chat-Deep.ai or DeepSeek; or
use the Service in violation of applicable export-control or sanctions laws, or submit material that requires an authorization for export or release that you do not have;
use the Service in a way that causes or attempts to cause Thinkly For Digital Business to violate an applicable provider term or legal obligation.

If you use DeepSeek’s own services or reuse output from the former chat, you must comply with the applicable DeepSeek Terms of Use and any lawful provider usage requirement that applies to the request or output.

7. Your Inputs and Other Submissions

“User Content” includes contact messages, comments, feedback, code, links and other content you submit through the Service. For past use of the former chat, it also includes prompts, pasted text and other material submitted through that feature. This description does not offer a current upload or chat feature.

You retain any rights you have in your User Content. You represent that you have all rights, licenses, permissions, consents, and legal authority required to submit it and permit the processing described in these Terms and our Privacy Policy.

You grant Thinkly For Digital Business a non-exclusive, worldwide, royalty-free license to host, reproduce, transmit, process, format, moderate, and display User Content only as reasonably necessary to provide, secure, troubleshoot, maintain, and enforce the Service, respond to your request, comply with law, and protect rights and safety.

This operational license ends when it is no longer reasonably necessary for those purposes, subject to legal obligations, provider processing, security and diagnostic records, backups, and content you intentionally made public.

Public comments or contributions may be visible to anyone. We may refuse, hide, format, moderate, or remove a submission that violates these Terms, constitutes spam, creates legal or security risk, or is otherwise inappropriate. We are not required to publish or preserve a submission.

If you submit feedback, corrections, ideas, or feature suggestions, you permit us to review and use them without compensation or an obligation to implement them, while retaining any rights that cannot lawfully be waived.

8. AI Outputs, Verification, and Disclosure

Responses produced through the former browser chat were generated by artificial intelligence. Our publication may also discuss or reproduce AI-generated examples as part of guides and research. AI output may be inaccurate, incomplete, outdated, biased, offensive, fabricated, insecure, or unsuitable for your circumstances. It may omit important context, present speculation as fact, or cite sources that do not exist.

You are responsible for independently reviewing, testing, and verifying output before relying on it, publishing it, using it commercially, executing code, making a decision, or providing it to another person. Use primary and authoritative sources for consequential facts. Apply appropriate human review and security testing to code, configurations, calculations, translations, and other consequential material.

If you publish or disseminate output from the former chat or AI-generated examples from our publication, you must verify its authenticity and accuracy, clearly disclose that the material was generated or assisted by artificial intelligence where required by applicable law or provider terms, and avoid publishing unlawful or prohibited content.

The same or similar output may be generated for other users. We do not promise that an output is original, unique, protectable, accurate, safe, non-infringing, or exclusively yours.

Subject to applicable law, third-party rights, and applicable provider terms, you may use output for lawful personal, educational, informational, or business purposes. This does not transfer a right that Thinkly For Digital Business does not own and does not grant rights in DeepSeek models, provider technology, third-party materials, trademarks, or other protected content.

9. No Professional Advice or High-Risk Reliance

The Service, including AI examples and output retained from the former chat, is for general informational and educational purposes. They are not legal, medical, financial, tax, investment, accounting, employment, cybersecurity, engineering, emergency, or other professional advice.

Do not use the Service as the sole basis for a diagnosis, treatment, legal deadline, financial transaction, employment decision, safety decision, security-incident response, or another decision where an error could cause serious harm. Consult an appropriately qualified professional and verify information using authoritative sources.

For an emergency, contact the appropriate emergency service or qualified professional. Do not rely on the Service for emergency assistance.

10. Advertising and Invalid Traffic

We may display advertising, including advertising delivered through Google AdSense. Advertising helps support the Service. Displaying an advertisement does not mean that Thinkly For Digital Business endorses the advertiser, product, service, website, offer, or claim. Your dealings with an advertiser are between you and that advertiser.

You must not create or encourage invalid advertising traffic. You must not:

click an advertisement to support the website, test an advertisement, generate revenue, or manipulate metrics;
ask, reward, pressure, or incentivize another person to view or click advertisements;
use bots, scripts, automated browsers, click farms, traffic exchanges, deceptive referrals, or purchased traffic intended to generate artificial impressions or interactions;
repeatedly refresh pages or interact with advertisements in an artificial or deceptive way; or
interfere with advertising delivery, consent signals, measurement, fraud detection, or advertising security systems.

We may restrict access and cooperate with advertising, analytics, consent, and security providers when activity appears to create invalid traffic or violate applicable policies.

11. Intellectual Property and Trademarks

Unless otherwise stated, the original text, site design, layout, graphics, code, and other materials created for Chat-Deep.ai are owned by or licensed to Thinkly For Digital Business and are protected by applicable intellectual-property laws.

We grant you a limited, revocable, non-exclusive, non-transferable permission to access and use the Service for lawful personal, educational, informational, or internal business purposes in accordance with these Terms.

This permission does not authorize you to republish substantial portions of the website, systematically copy our database or articles, resell the Service, remove rights notices, impersonate us, or use our content or branding in violation of law or these Terms.

Third-party names, trademarks, service marks, product names, model names, logos, and brand features—including DeepSeek and its model names—remain the property of their respective owners. Their appearance on Chat-Deep.ai does not transfer ownership or imply affiliation, authorization, sponsorship, certification, or endorsement.

If you believe material on the Service infringes your copyright, trademark, privacy, publicity, or another right, contact info@chat-deep.ai. Include the affected URL, a description of the material and claimed right, your contact information, and enough information for us to evaluate the request.

12. Official Resources and External Services

Use official DeepSeek resources for official accounts, login, application downloads, API keys, billing, balances, pricing, refunds, platform support, and official legal terms:

External links are provided for convenience and source verification. We do not control third-party websites and are not responsible for their availability, security, privacy practices, content, prices, terms, products, or actions. Your use of an external service is governed by that service’s own terms and policies.

13. Availability, Changes, and Fair Use

The Service may be limited by maintenance, hosting or network failures, upstream capacity, provider changes, abuse controls, legal requirements or other events. Pages, informational tools or responses to inquiries may be delayed, incomplete or unavailable.

DeepSeek’s official services remain separate and subject to their own availability, terms and policies. Do not attempt to bypass access or security controls on this site or an external service.

We may apply request, frequency, traffic or other reasonable limits to protect the Service, control costs, maintain availability, and prevent abuse. Limits may vary according to technical and operational conditions.

We may add, remove, update, limit, suspend, or discontinue a feature or any part of the Service. We do not guarantee continued access to a particular page, tool, feature, interface, provider or external link, or continuing coverage of a particular model.

Unless we expressly enter into a separate written agreement with you, the Service includes no uptime, response-time, support-response, data-recovery, or service-credit commitment. Public status information is informational and does not constitute a service-level agreement or warranty.

14. Restriction, Suspension, and Termination

We may rate-limit, restrict, block, suspend, or terminate access to all or part of the Service when we reasonably believe this is necessary to:

enforce these Terms or an applicable provider requirement;
prevent abuse, invalid advertising traffic, fraud, automated overload, or security threats;
protect users, the Service, advertisers, providers, rights holders, or the public;
respond to legal process or comply with applicable law;
protect our API credentials, infrastructure, reputation, or contractual relationships; or
address technical, safety, privacy, legal, or operational risk.

Where appropriate and reasonably practicable, we may provide notice or an opportunity to correct a violation. We are not required to provide advance notice when immediate action is reasonably necessary. You may stop using the Service at any time.

15. Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE IS PROVIDED “AS IS,” “AS AVAILABLE,” AND “WITH ALL FAULTS.” Thinkly For Digital Business DISCLAIMS WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, RELIABILITY, SECURITY, AVAILABILITY, AND QUIET ENJOYMENT.

We do not warrant that the Service will be uninterrupted, error-free, secure, free of harmful components, available in every location, or compatible with every device. We do not warrant that website content or AI output will be accurate, complete, lawful, original, non-infringing, or fit for your intended purpose, or that a defect will be corrected.

Some laws do not permit certain warranty exclusions. Nothing in these Terms excludes a warranty, remedy, or right that cannot lawfully be excluded.

16. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, Thinkly For Digital Business, CHAT-DEEP.AI, AND THEIR OFFICERS, PERSONNEL, CONTRIBUTORS, CONTRACTORS, AND SERVICE PROVIDERS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOSS OF PROFITS, REVENUE, BUSINESS, OPPORTUNITY, GOODWILL, REPUTATION, OR DATA, ARISING OUT OF OR RELATING TO THE SERVICE, THIRD-PARTY SERVICES, AI OUTPUT, OR YOUR INABILITY TO USE THE SERVICE.

Any direct liability that cannot lawfully be excluded or disclaimed is limited only to the extent permitted by applicable law.

These limitations apply regardless of legal theory and even if the possibility of loss was disclosed. They do not limit liability for fraud, wilful misconduct, death or personal injury caused by negligence where such liability cannot be limited, or any mandatory consumer right or other liability that applicable law does not permit us to exclude or restrict.

17. Business Use and Indemnity

If you use the Service on behalf of a company, organization, employer, or other legal entity, you represent that you have authority to act on its behalf and bind it to these Terms.

To the maximum extent permitted by applicable law, a business or organizational user agrees to defend, indemnify, and hold harmless Thinkly For Digital Business and its personnel from third-party claims, damages, liabilities, and reasonable costs arising from that user’s unlawful User Content, infringement of third-party rights, unauthorized submission of personal or confidential information, or material violation of these Terms.

This section does not apply to an individual consumer where such an obligation is prohibited or restricted by mandatory law and does not cover losses caused by our fraud, wilful misconduct, or liability that cannot lawfully be excluded.

18. Mandatory Rights and Severability

Nothing in these Terms is intended to restrict a privacy, data-protection, consumer-protection, accessibility, intellectual-property, or other right that cannot lawfully be restricted.

If a provision is invalid or unenforceable in a particular situation, it will be limited or interpreted only to the minimum extent necessary. The remaining provisions will continue to apply.

19. Governing Law and Disputes

These Terms and any non-contractual obligations arising from or relating to them are governed by the laws of the Arab Republic of Egypt, without regard to conflict-of-law principles, except where mandatory law requires otherwise.

Subject to any mandatory consumer-protection, privacy, or jurisdictional right that applies to you, disputes arising from or relating to the Service or these Terms will be submitted to the competent courts of the Arab Republic of Egypt.

Nothing in this section prevents either party from requesting urgent injunctive or protective relief from a court with lawful jurisdiction, and nothing removes a consumer’s mandatory right to bring a claim before another competent court where applicable law grants that right.

20. Changes to These Terms

We may update these Terms to reflect changes to the Service, informational tools, provider requirements, security practices, advertising or analytics services, legal obligations, or operational practices.

The Effective Date and Last Verified date displayed at the beginning identify the applicable version. Where appropriate or required by law, we will provide additional notice of a material change. Changes apply prospectively from the effective date stated in the updated Terms.

Your continued use after updated Terms take effect constitutes acceptance only to the extent permitted by applicable law. If you do not agree with an update, stop using the Service.

21. General Provisions

Entire agreement: These Terms, together with the Privacy Policy, Cookie Policy, and any applicable feature notice, form the agreement between you and Thinkly For Digital Business concerning the Service, except where a separate written agreement expressly applies.
No waiver: A failure to enforce a provision does not waive the right to enforce it later.
Severability: If a provision is unenforceable, the remaining provisions remain effective.
Assignment: You may not assign your rights or obligations under these Terms without our written consent. We may transfer rights and obligations in connection with a genuine sale, merger, restructuring, or transfer of the Service, subject to applicable law.
No third-party beneficiary: Except where these Terms expressly state otherwise, they do not create enforceable rights for a third party.
Headings: Headings are provided for readability and do not change the meaning of these Terms.
Translations: A translation may be provided for convenience. If versions conflict, the English version controls to the extent permitted by applicable law.
