Terms of Service

Last updated: 28 July 2026

1. About Musterly

Musterly is a workplace presence and safety service operated by Brix Systems Limited, trading as Musterly. We are registered in England and Wales under company number 17123063.

These terms apply to the Musterly website and application. By creating an account or using the service, you agree to them. If you use Musterly for an organisation, you confirm that you have authority to accept these terms for that organisation.

2. The service

Musterly provides tools that help organisations:

  • understand who is present at one or more workplaces;
  • conduct roll calls and emergency muster activities;
  • review attendance information;
  • manage visitors and workplace safety roles; and
  • connect supported access-control systems, including UniFi Access.

The service may include trial access, self-service setup and assisted setup. Features available to an organisation may depend on its subscription and configuration.

3. Accounts and organisations

Musterly is intended for organisations. Each organisation is responsible for:

  • providing accurate account and organisation information;
  • keeping account credentials secure;
  • giving users appropriate permissions;
  • making employees, visitors and other affected people aware of its use; and
  • complying with employment, privacy and data protection law.

Tell us promptly if you believe an account has been accessed without permission.

4. Acceptable use

You must use Musterly lawfully and responsibly. You must not:

  • process information that you are not authorised to handle;
  • track people without their knowledge where doing so would be unlawful;
  • attempt to access another organisation's account or data;
  • interfere with the security or operation of the service;
  • scrape, reverse-engineer or exploit the service except where law expressly permits it; or
  • use Musterly in a way that infringes another person's rights.

We may restrict or suspend access where reasonably necessary to protect the service, our customers or other people, or to comply with law.

5. Your data

You and your organisation keep your rights in information submitted to Musterly. You give us permission to process that information as needed to provide, secure and support the service. Our Privacy Notice explains how personal information is handled.

The main Musterly application database is hosted in the European Union. We access an organisation's application data only as needed to provide and secure the service, deliver support requested by the organisation, or comply with law.

After cancellation, an organisation normally has 30 days to export its data. We then delete the data, subject to any legal requirement to keep limited records for longer.

6. Integrations

Musterly can connect to third-party services, including supported access-control systems. Your organisation is responsible for having permission to connect those services and for complying with the third party's terms.

Unless we say otherwise, Musterly is not affiliated with or endorsed by third-party access-control providers. We are not responsible for changes, outages or errors in a third-party service that are outside our control.

7. Service availability

We aim to provide a reliable service, but we cannot guarantee that Musterly will always be available or error-free. We may carry out maintenance, make updates, change features or experience outages. Where practical, we will give notice of planned downtime that is likely to have a material effect.

Musterly supports workplace safety processes but does not replace an organisation's legal duties, emergency procedures, professional judgement or primary life-safety systems.

8. Limitation of liability

To the maximum extent permitted by law, Brix Systems Limited is not liable for indirect or consequential loss arising from use of Musterly, including loss of revenue, loss of data or reliance on presence and roll-call information for safety-critical decisions.

Nothing in these terms excludes or limits liability for death or personal injury caused by negligence, fraud, fraudulent misrepresentation, or any other liability that cannot legally be excluded or limited.

9. Intellectual property

Musterly's software, design, trademarks and content belong to Brix Systems Limited or its licensors. These terms give you a limited right to use the service for your organisation. They do not transfer ownership of our intellectual property to you.

10. Governing law

The laws of England and Wales govern these terms. The courts of England and Wales have exclusive jurisdiction over disputes relating to them.

11. Changes to these terms

We may update these terms when the service or legal requirements change. We will give reasonable notice of material changes by email, in the application or on the website. If you continue to use Musterly after the updated terms take effect, the updated terms will apply to that use.
