Terms of service

Last updated 12 November 2026. This document is still being reviewed and may change before hosted sign-up opens.

1. What these terms cover

Murmura is team chat made by Dusk Engineering Services Ltd, a company registered in England and Wales ("we", "us"). These terms cover hosted Murmura: the service we run at app.murmura.co.uk, and the Murmura apps when they are connected to it.

If you run Murmura on your own server, these terms do not apply to that server. Your agreement with us for the software covers it.

By creating an organisation or an account on hosted Murmura, or by using one, you agree to these terms.

2. Organisations and accounts

An organisation is the customer: the company, team or group that a set of workspaces belongs to. If you create an organisation, you confirm that you are allowed to agree to these terms on its behalf.

• The organisation's owners decide who can join, what role each person has, and how its workspaces are set up. The organisation is responsible for how its people use Murmura.
• Each person signs in with their own account. Keep your password and any two-factor codes to yourself, and tell your organisation's admins if you think someone else has used your account.
• Give us accurate details, including an email address you can read.
• Murmura is for use at work. You must be at least 16 to hold an account.

3. Your content

Messages, files, notes, recordings and anything else your organisation puts into Murmura ("content") belong to you or to whoever gave them to you. We do not claim ownership of them.

You give us permission to store, copy, back up, display and send content only as needed to run the service for you, for example to deliver a message to the other people in a room.

We do not sell content, we do not use it for advertising, and we do not use it to train machine-learning models.

4. Acceptable use

Everyone using hosted Murmura must follow the acceptable use policy. It forms part of these terms.

5. Plans, limits and payment

• Each organisation has a limit on the number of people and on file storage. The limits that apply to your organisation are shown in its Organisation screen.
• Where we offer paid plans, the price and what the plan includes are shown before you pay. Payment is taken in advance through our payment provider, Stripe, and the plan renews until you cancel it.
• An owner can change or cancel a paid plan at any time from the Organisation screen. A cancelled plan runs to the end of the period already paid for.
• When a paid plan ends, the organisation goes back to the standard limits. Nothing is deleted, but you cannot add people or files beyond those limits until you are back within them.
• Payments are not refundable, except where the law says otherwise.
• We may change prices. We will give owners at least 30 days' notice before a change applies to an existing plan.

6. Availability, support and changes

We work to keep Murmura running and your data safe, but we do not promise that it will always be available or free of faults, unless we have agreed a service level with you in writing. We may take the service down for short periods for maintenance.

Support is by email at info@duskengineering.services, during UK working hours.

We add to and change Murmura over time. If we plan to remove something your organisation is likely to depend on, we will give reasonable notice first.

7. Personal data

Our privacy policy explains what we hold about the people who use Murmura and why.

For the personal data inside your organisation's content, your organisation decides what is collected and why, and we handle it on your organisation's behalf. The data processing agreement sets out how, and forms part of these terms.

8. Leaving, suspension and ending

• Any person can download their own data and delete their own account from Preferences. Their messages stay in the conversations they were part of, shown as written by "Deleted user", because those conversations belong to the organisation.
• An owner can export the organisation's data and delete the organisation at any time from the Organisation screen. Deleting an organisation removes its workspaces, messages and files. Backup copies are gone within 30 days.
• We may suspend an organisation or an account that breaks these terms, puts the service or other customers at risk, or has not paid what it owes. Where we can, we will tell the owners first and give them a chance to put things right.
• We may end our agreement with an organisation if it seriously or repeatedly breaks these terms, or for any other reason on 30 days' notice. If we end it without the organisation being at fault, we will refund any period already paid for and not used.
• Before we delete an organisation's data at the end of the agreement, the owners will have at least 30 days to export it, unless the law requires us to remove it sooner.

9. Our software

We own Murmura: the software, the apps, the name and the design. These terms let you use the hosted service; they do not give you any other rights in it. If you send us ideas or feedback, we may use them without owing you anything.

10. Liability

Hosted Murmura is supplied for business use. As far as the law allows:

• we exclude any warranties or terms that are not written in these terms;
• we are not liable for loss of profit, loss of business, or indirect or consequential loss;
• our total liability to an organisation in any 12 months is limited to the amount it paid us for Murmura in those 12 months.

Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot be limited by law.

11. Changes to these terms

We may update these terms. If a change matters to how you use Murmura, we will tell owners by email or in the app at least 30 days before it applies. If you keep using Murmura after a change applies, you accept it.

12. General

• These terms, the acceptable use policy and the data processing agreement are the whole agreement between us about hosted Murmura.
• If a court finds part of these terms cannot be enforced, the rest still applies.
• You may not transfer your agreement with us to someone else without our consent. We may transfer it to a company that takes over Murmura, and will tell you if we do.
• These terms are governed by the law of England and Wales, and the courts of England and Wales decide any dispute about them.
