  1. the Product;
  2. non-public technical information;
  3. business or commercial information; and

  • (b) is or becomes publicly available through no breach of this Agreement;
  • (c) is independently developed without use of Confidential Information; or
  • (d) is lawfully obtained from a third party without breach of any confidentiality obligation.

Licensee shall:

protect Confidential Information using at least reasonable care, and in no event less than the degree of care it uses to protect its own confidential information of a similar nature;

use Confidential Information solely as necessary to exercise its rights under this Agreement; and

not disclose Confidential Information to any third party except to employees or contractors who have a legitimate need to know and are bound by confidentiality obligations.

Licensee may disclose Confidential Information where required by law or court order, provided that, where legally permitted, Licensee gives prior notice to 3CX and cooperates in seeking appropriate protective measures.

These confidentiality obligations shall survive termination of this Agreement for so long as the relevant information remains confidential under applicable law.

Each party agrees that it shall not knowingly make false statements of fact about the other party or its products that are likely to cause material reputational harm.

7.1  Limited Warranty

3CX warrants that, for a period of fourteen (14) days following initial activation of the applicable license key (the “Warranty Period”), the Product will substantially conform to its accompanying written documentation when used in accordance with this Agreement.

If the Product fails to conform to this limited warranty during the Warranty Period, 3CX’s sole obligation and Licensee’s exclusive remedy shall be, at 3CX’s option:

(a) to repair or replace the non-conforming Product; or

(b) to refund the license fees paid to 3CX for the affected Product.

This limited warranty does not apply to:

  • misuse or unauthorized modification of the Product;

  • loss of profits, loss of revenue, loss of data, business interruption, or loss of goodwill;
  • arising out of or in connection with this Agreement or the use of the Product, even if advised of the possibility of such damages.

Subject to Clause 8.4, the total aggregate liability of 3CX arising out of or in connection with this Agreement shall not exceed the amount actually paid by Licensee to 3CX for the Product giving rise to the claim during the twelve (12) months preceding the event giving rise to liability.

Upon termination:

  1. all rights granted to Licensee shall immediately cease;
  2. Licensee shall cease using the Product; and
  3. Licensee shall delete or destroy all copies of the Product, except where retention is required by law.

Any disputes arising out of or in connection with this Agreement shall be subject to the exclusive jurisdiction of the courts of the Contracting Entity’s registered office, unless applicable consumer protection laws provide otherwise.

The United Nations Convention on Contracts for the International Sale of Goods (CISG) shall not apply.

11.  Equitable Relief

Licensee acknowledges that unauthorized use or disclosure of the Product may cause irreparable harm to 3CX for which monetary damages may be inadequate. Subject to applicable law, 3CX shall be entitled to seek appropriate injunctive or equitable relief in a court of competent jurisdiction in addition to any other remedies available at law.

12. Copyrights And Trademarks

All intellectual property rights in and to the Product, including software, documentation, trademarks, logos, and related materials, are owned by 3CX or its licensors.

If Licensee becomes aware of any infringement of 3CX’s intellectual property rights in connection with the Product, it shall notify 3CX.

13. Regulatory Compliance – Disclaimer

Licensee acknowledges that it is solely responsible for assessing its own compliance with applicable legal, regulatory, or supervisory requirements arising from its use of the Product, including without limitation Regulation (EU) 2022/2554 on Digital Operational Resilience for the Financial Sector (“DORA”).

Unless expressly agreed in writing, 3CX does not represent or warrant that the Product is specifically designed to meet any particular regulatory framework applicable to Licensee.

Licensee remains responsible for conducting its own due diligence and implementing any additional contractual, technical, or organizational measures required for regulatory compliance.

Nothing in this Clause excludes liability for misrepresentation or for any liability that cannot be excluded under applicable law.

14. Hosting Acceptable Use

Licensee agrees to use the 3CX hosting platform lawfully and responsibly. Licensees may not use the platform to host, store, transmit, or distribute any content or engage in any activity that is illegal, harmful, or malicious. This includes, without limitation: distributing malware, viruses, or other harmful code; launching or facilitating attacks such as denial-of-service (DoS/DDoS), hacking, or unauthorized access to systems or data; sending spam or unsolicited bulk communications; phishing, fraud, or any deceptive practices; infringing the intellectual property rights of others; hosting or distributing content that is defamatory, obscene, abusive, or that promotes violence or discrimination; violating the privacy of others; or attempting to disrupt, overload, or compromise the integrity, security, or performance of the platform or its infrastructure.

3CX reserves the right to suspend or terminate free licenses at any time, with or without notice, if it has reason to believe that these Terms of Service or this Acceptable Use Policy have been violated.  For paid licenses, 3CX will generally provide notice of any violation and a reasonable opportunity to remedy it before suspending or terminating the account, except where the violation is severe, poses an immediate risk to the platform, other users, or third parties, or where it is required to act immediately by law. In such cases, 3CX reserves the right to suspend or terminate paid licenses immediately and without prior notice.

15. Regulatory Suitability Disclaimer – Hosted Version

The hosted version of the 3CX Product is a standardized, shared service offering. It is not tailored to meet the specific legal, regulatory, or supervisory requirements applicable to regulated financial entities under Regulation (EU) 2022/2554 on Digital Operational Resilience for the Financial Sector ("DORA").

3CX makes no representations or warranties that the hosted deployment satisfies the technical, contractual, or operational requirements under DORA, including but not limited to ICT risk management, audit rights, data localization, or incident reporting obligations. Accordingly, customers who are subject to DORA or other sector-specific ICT risk regulations should not rely on the hosted version of the 3CX Product to meet those obligations and are advised to deploy the Software in an on-premise or self-hosted environment. Use of the hosted version is at the Licensee’s sole risk and does not create any responsibility or liability on the part of 3CX for regulatory non-compliance.
