Acceptable Use Policy

Last updated: 9 May 2026

This Acceptable Use Policy ("AUP") applies to your use of Messenger by Chattriix (the "Service"). It supplements the Terms of Service. By using the Service you agree to comply with this AUP.

We're a privacy-first messenger and we cannot read your messages. That makes responsibility for what you send especially clear: it rests with you. This policy explains what's not allowed and what we'll do if it happens anyway.

1. What's not allowed

You may not use the Service to:

1.1 Illegal activity

  • Send Content that is unlawful in your jurisdiction or in the United Kingdom.
  • Distribute child sexual abuse material (CSAM). We report any such material we become aware of to the relevant authorities.
  • Engage in fraud, money laundering, or other financial crimes.
  • Violate sanctions or export-control regulations.

1.2 Harm to others

  • Threaten, harass, stalk, or intimidate any person.
  • Incite violence or hatred against any group.
  • Distribute non-consensual intimate imagery.
  • Engage in coordinated harassment campaigns.

1.3 Spam and abuse

  • Send unsolicited bulk messages.
  • Mass-create accounts or use automated means to send messages at scale without authorisation.
  • Use the Service primarily to drive traffic to commercial offerings unrelated to the conversation.
  • Distribute phishing links or social-engineering scams.

1.4 Harm to the Service

  • Distribute malware, ransomware, or malicious links through the Service.
  • Probe, scan, or test the vulnerability of any part of the Service without prior written authorisation (responsible disclosure to security@chattriix.com is welcomed).
  • Attempt to circumvent authentication, rate limits, or other security measures.
  • Reverse-engineer the Service except as expressly permitted by applicable law.
  • Use the Service to mine cryptocurrency or perform any computationally expensive workload that's not the Service's intended purpose.
  • Interfere with or disrupt the Service or its underlying infrastructure.

1.5 Misuse of the encryption guarantee

The end-to-end encryption design of Messenger means we cannot moderate content. This is a feature for honest users and a responsibility for everyone. Using encryption as cover for activity that would be illegal in plaintext is still illegal, and you remain personally responsible.

1.6 Impersonation and misrepresentation

  • Impersonate any person or organisation.
  • Misrepresent your affiliation with another entity.
  • Use display names or avatars designed to deceive.

1.7 Intellectual property

  • Distribute copyrighted material without permission.
  • Distribute trade secrets you have no right to share.
  • Use Chattriix's trademarks (including the "Chattriix" name and the Messenger logo) without our permission.

2. Consequences of violations

If we have credible evidence that an Account or Organisation is being used in violation of this AUP, we may:

  • Warn the Account holder or Organisation administrator.
  • Suspend the Account or specific Organisation features pending investigation.
  • Terminate the Account permanently.
  • Refer to law enforcement where the activity appears to violate criminal law.
  • Preserve evidence as required by law enforcement requests, recognising that we typically cannot decrypt the content of messages.

For Organisation-level violations, we will engage with the Organisation administrator first where possible, except in cases of urgent harm.

3. Reporting violations

If you encounter content or behaviour that violates this AUP, please report it:

  • In the app: use the report feature on a specific message, conversation, or user.
  • By email: abuse@chattriix.com for general abuse, security@chattriix.com for security-related issues, csam@chattriix.com for child safety concerns.

When you report content via the in-app reporter, you choose what context to share with us. By design, we cannot see the content of a message unless you explicitly share it with us as part of the report.

4. Government and law-enforcement cooperation

We comply with valid legal process in the United Kingdom. Because of the end-to-end encryption design of the Service:

  • We can produce account metadata (e.g., when an account was created, IP addresses associated with sessions where lawful and held).
  • We can produce encrypted content in the form we hold it, which is not decryptable by us.
  • We cannot produce plaintext message content because we do not have it.

We do not voluntarily provide user data to authorities outside valid legal process. Once we have a meaningful track record of legal-process activity, we will publish a transparency report.

5. Self-hosted deployments

If you use the Service via a self-hosted deployment operated by your organisation, your organisation may impose additional acceptable-use rules on top of this AUP. Speak to your organisation's administrator for the rules that apply to you.

6. Changes

We may update this AUP from time to time. Material changes will be notified through the Service. Continued use after changes take effect constitutes acceptance.
