Terms of Service

Last updated: 9 May 2026 Effective: 9 May 2026

These Terms of Service ("Terms") govern your use of Messenger by Chattriix (the "Service"), provided by Nexa Lucent Technologies Ltd ("Chattriix", "we", "us"). By creating an account or otherwise using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. Definitions

  • "Service" — the Messenger by Chattriix software, including iOS app, Android app, web app, and supporting backend services.
  • "You" — the individual or organisation using the Service.
  • "Account" — your authenticated identity within the Service.
  • "Content" — anything you transmit through the Service (messages, media, calls).
  • "Organisation" — a customer entity that has deployed the Service for use by its members.

2. Eligibility

You must be at least 16 years old (or the minimum age in your jurisdiction, whichever is higher) to use the Service. If you are using the Service on behalf of an organisation, you represent that you have authority to bind that organisation to these Terms.

3. Account responsibilities

  • You are responsible for maintaining the confidentiality of your Account credentials and for all activity under your Account.
  • You must provide accurate information when creating your Account.
  • You must notify us promptly at security@chattriix.com if you suspect unauthorised access to your Account.
  • You may not share your Account with others, transfer it, or use someone else's Account without permission.

4. Acceptable use

You agree not to use the Service to:

  • Send unlawful, harmful, threatening, abusive, harassing, defamatory, or otherwise objectionable Content.
  • Impersonate any person or entity.
  • Send unsolicited commercial messages (spam).
  • Distribute malware, exploit vulnerabilities, or otherwise attempt to compromise the Service or other users.
  • Infringe the intellectual property or privacy rights of others.
  • Engage in activity that violates applicable law (including export controls, sanctions, child protection laws, and data protection laws).
  • Attempt to circumvent security measures, access-control mechanisms, or rate limits.
  • Reverse engineer or attempt to extract source code from compiled binaries, except to the extent permitted by applicable law (e.g., for interoperability under copyright exceptions).

A more detailed Acceptable Use Policy is available at https://chat.chattriix.com/aup.

5. Your Content

  • You retain ownership of the Content you transmit through the Service.
  • You grant us a limited, non-exclusive, worldwide licence to host, transmit, and deliver your Content for the sole purpose of operating the Service. This licence terminates when you delete the Content (subject to backup-rotation timelines documented in our Privacy Policy).
  • Because your Content is end-to-end encrypted, the practical scope of this licence is limited to handling ciphertext on our infrastructure.
  • You represent that you have the right to share the Content you transmit and that doing so does not violate any third-party rights or applicable law.

6. End-to-end encryption

The Service is designed with end-to-end encryption such that we cannot read the contents of your messages, calls, or shared media. We do not provide, and cannot provide, a mechanism for ourselves to access your plaintext Content.

This has practical consequences:

  • We cannot recover messages or media from a device you have lost or that has been wiped, beyond what is available on your other authenticated devices.
  • We cannot moderate or scan your Content for compliance, illegal content, or any other purpose. Responsibility for the lawfulness of Content rests with the sender.
  • Law-enforcement requests can only be answered with respect to data we actually hold (account metadata, routing information, encrypted blobs we cannot decrypt). See our Privacy Policy for details.

7. Service availability

We aim to keep the Service highly available but do not guarantee uninterrupted service. Maintenance, network outages, or third-party dependencies may cause downtime. The Service is provided on an "as is" and "as available" basis.

For paid Organisation plans, separate Service Level Agreements ("SLAs") may apply — see your Order Form or organisational agreement.

8. Pricing and payment

  • The Service may be offered free of charge for individual or limited use, and on paid plans for Organisations.
  • Pricing for paid plans is published on our website or set out in your Order Form. Pricing changes apply only to billing periods that begin after we notify you.
  • Paid plans are billed in advance, non-refundable except where required by law.
  • All fees are exclusive of VAT and other applicable taxes, which we will charge as required.
  • Late payment may result in suspension of the relevant Account or Organisation.

9. Intellectual property

  • The Service, including all software, designs, logos, and content other than Your Content, is owned by Chattriix or its licensors and is protected by intellectual property laws.
  • We grant you a limited, non-exclusive, non-transferable, revocable licence to use the Service in accordance with these Terms.
  • You may not copy, modify, distribute, sell, or lease any part of the Service or its source code (except as expressly permitted, e.g., for self-hosted deployments licensed separately).
  • "Chattriix" and "Messenger by Chattriix" are trademarks of Nexa Lucent Technologies Ltd.

10. Termination

By you

You may delete your Account at any time from within the Service or by emailing support@chattriix.com. Deletion takes effect within 30 days, after which your personal data is removed in accordance with our Privacy Policy.

By us

We may suspend or terminate your access to the Service if:

  • You materially breach these Terms.
  • Your use of the Service threatens the security or availability of the Service for others.
  • We are required to do so by law.
  • The Service is discontinued in your jurisdiction.

We will give you reasonable notice except where immediate action is necessary (e.g., to prevent ongoing abuse or comply with legal process).

After termination, the obligations in Sections 5 (Your Content), 9 (Intellectual Property), 11 (Disclaimers), 12 (Limitation of Liability), 14 (Governing Law), and 15 (Miscellaneous) survive.

11. Disclaimers

EXCEPT AS EXPRESSLY SET OUT IN THESE TERMS OR REQUIRED BY LAW, THE SERVICE IS PROVIDED "AS IS" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, OR THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE.

We do not warrant that the Service will meet every requirement you may have, or that any data or message will be delivered without delay.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW:

  • WE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOSS OF PROFITS, REVENUE, GOODWILL, USE, DATA, OR OTHER INTANGIBLE LOSSES.
  • OUR TOTAL LIABILITY ARISING OUT OF OR IN CONNECTION WITH THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID US IN THE 12 MONTHS PRECEDING THE EVENT GIVING RISE TO LIABILITY, OR (B) £100.

Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or any other liability that cannot be excluded under English law.

13. Indemnification

You agree to indemnify and hold harmless Chattriix and its officers, employees, and agents from any third-party claims arising out of (a) Content you transmit through the Service, (b) your breach of these Terms, or (c) your violation of applicable law in connection with your use of the Service. This obligation does not apply to the extent the claim arises out of our negligence or wilful misconduct.

14. Governing law and jurisdiction

These Terms are governed by the laws of England and Wales. The courts of England and Wales have exclusive jurisdiction over any dispute, except that we may bring proceedings to enforce intellectual property rights in any competent court.

If you are a consumer (not using the Service in the course of a business), you may also bring proceedings in the courts of your country of residence, and you have the benefit of any non-excludable consumer-protection rights in your jurisdiction.

15. Miscellaneous

  • Entire agreement. These Terms (together with the Privacy Policy and any applicable Order Form or organisational agreement) form the entire agreement between you and us regarding the Service.
  • Changes. We may update these Terms from time to time. Material changes will be notified at least 30 days in advance for paid Organisation plans, and through in-app notice for individual users. Continued use after the effective date constitutes acceptance.
  • Severability. If any provision is held unenforceable, the rest remains in effect.
  • No waiver. Our failure to enforce a provision is not a waiver of our right to do so later.
  • Assignment. You may not assign or transfer these Terms without our consent. We may assign these Terms in connection with a merger, acquisition, or reorganisation, with notice to you.
  • No third-party rights. Except as expressly stated, these Terms do not give rights to anyone other than you and us under the Contracts (Rights of Third Parties) Act 1999.
  • Force majeure. Neither party is liable for delays or failures caused by events beyond reasonable control (natural disasters, war, internet outages affecting third-party infrastructure, etc.).
