Effective date: 2026-10-02
These Terms of Use (“Terms”) govern your access to and use of the Mezzo mobile application, associated web services, cloud services and related functionality (“Mezzo” or the “Service”).
The Service is provided by Ness Corporation Pty Ltd (ABN 28 069 984 372) (“Ness”, “we”, “us” or “our”), located in Seven Hills, New South Wales 2147, Australia.
By creating a Mezzo account, accessing or using the Service, or purchasing a Mezzo Premium subscription, you agree to these Terms.
If you do not agree to these Terms, you must not use the Service.
1. About Mezzo
Mezzo provides remote access, control, notification, security and home-automation functionality for compatible Ness products and systems.
Depending on your equipment, configuration, account type and subscription status, Mezzo may allow you to remotely arm or disarm a compatible security system, receive event notifications, review event information, operate automation functions, configure scenes and access other functionality made available by Ness.
The availability of particular functions may depend on compatible Ness hardware, internet connectivity, mobile network connectivity, third-party services, device permissions, operating-system functionality and the version of the Mezzo application you are using.
2. Accounts
Certain Mezzo functions require a registered account.
You must provide information that is accurate and reasonably current and must keep your login credentials secure.
You are responsible for activities carried out through your account, except to the extent those activities result from a matter for which Ness is legally responsible.
You must notify Ness as soon as reasonably practicable if you become aware of unauthorised access to your account.
You must not use another person’s account without authority or use Mezzo to access or control a security or automation system that you are not authorised to access.
3. Mezzo Free
Ness may make a free level of the Service available.
The current Mezzo Free service includes remote arm and disarm functionality for supported systems, limited event-history functionality and an allowance of up to 10 push notifications during each monthly allowance period.
All push-notification types count towards this allowance, including alarm events, arm events, disarm events, automation events and other supported notifications.
Once the Free push-notification allowance has been exhausted, no further push notifications will be delivered through Mezzo until the allowance resets. This includes alarm notifications.
The current allowance usage and reset information may be displayed within the application.
Ness may change the features or limits of the Free service from time to time in accordance with section 13.
4. Important security and notification limitations
Mezzo is a supplementary remote-access and notification service.
Unless Ness has expressly agreed otherwise under a separate written monitoring-service agreement, Mezzo is not a professional alarm-monitoring service, emergency service or guaranteed emergency-notification service.
Push notifications and remote commands rely on systems and infrastructure that may include your security equipment, local internet connection, mobile network, mobile device, operating system, Apple or Google notification infrastructure, third-party cloud infrastructure and Ness services.
Notifications may be delayed, unavailable, suppressed or not received because of circumstances including loss of connectivity, device settings, power loss, application permissions, operating-system restrictions, third-party outages, cloud-service outages, equipment failures or other technical conditions.
You must not rely on Mezzo push notifications as the sole means by which you become aware of an alarm, emergency or security event.
Free users should be particularly aware that all push notifications stop when the monthly notification allowance has been exhausted.
Where protection of people or property requires professional monitoring, emergency response or another high-availability service, you should arrange an appropriate service separately.
5. Mezzo Premium
Ness may offer a paid subscription service known as Mezzo Premium.
The current Premium service may include:
- remote arm and disarm functionality;
- push notifications for supported events without the Free service’s monthly notification quota;
- access to the full event-history functionality made available through Mezzo, subject to applicable system retention limits;
- virtual switch naming;
- scene functionality; and
- other functionality identified within Mezzo as being included with Premium.
The precise Premium features available to you may depend on your equipment, application version and system configuration.
Ness does not guarantee that every feature offered through Mezzo now or in the future will necessarily form part of the same subscription tier.
6. Subscription period and automatic renewal
Unless otherwise stated at the time of purchase, Mezzo Premium is offered as an automatically renewing monthly subscription.
Your subscription continues for successive monthly subscription periods until it is cancelled or otherwise terminates.
The subscription name, applicable subscription period and price will be displayed before you confirm your purchase.
7. Price and payment
Where Mezzo Premium is purchased through the Apple App Store, payment is processed through your Apple account in accordance with Apple’s applicable payment and subscription terms.
Where Mezzo Premium is purchased through Google Play, payment is processed through your Google Play account in accordance with Google’s applicable payment and subscription terms.
The amount charged is the price displayed by the applicable app store when you confirm the purchase, including any applicable taxes handled by that platform.
Ness may receive information from Apple or Google necessary to confirm and manage your subscription entitlement, such as subscription status, product identifiers and transaction information.
Ness does not ordinarily receive your full payment-card details for subscriptions processed by Apple or Google.
Ness may introduce additional authorised methods of purchasing or obtaining Premium access in the future. Any additional payment terms applicable to those methods will be disclosed before purchase.
8. Automatic renewal and cancellation
Unless cancelled, your Premium subscription will automatically renew at the end of each subscription period and the applicable platform may charge the payment method associated with your platform account.
You can cancel automatic renewal through the subscription-management facilities provided by Apple or Google, as applicable.
Deleting the Mezzo application from your device does not cancel a Premium subscription.
Deleting or closing your Mezzo account should also not be assumed to cancel an Apple or Google subscription. If you are deleting your Mezzo account, you should separately verify and, where necessary, cancel your active subscription through the applicable app store.
Unless applicable law or the relevant platform provides otherwise, cancelling automatic renewal does not immediately end a subscription period that has already been paid for. Premium access will generally remain available until the end of the current paid subscription period.
9. Expiry, cancellation and downgrade
When a Premium subscription expires or otherwise ends, your Mezzo service will revert to the functionality available under the Free service at that time.
This means, among other things, that the Free push-notification allowance will apply.
Premium configuration information, including virtual switch names, may be retained while your associated Mezzo or device account remains open. Premium-only functionality may be unavailable or restricted while there is no active Premium entitlement.
Ness does not guarantee indefinite storage of configuration or event information. Retention is subject to our Privacy Policy, applicable product functionality, legitimate operational requirements and applicable law.
If you later obtain Premium again, retained Premium configuration may become accessible again where technically supported.
10. Failed payments, refunds and chargebacks
If a subscription payment fails, is reversed or is otherwise not successfully completed, your Premium entitlement may be suspended or terminated in accordance with the applicable app-store processes.
For purchases processed by Apple or Google, refund requests may need to be submitted through the relevant platform and are also subject to that platform’s refund procedures.
Nothing in these Terms excludes, restricts or modifies any consumer guarantee, right or remedy that cannot lawfully be excluded, restricted or modified, including rights available under the Australian Consumer Law.
Where you are entitled to a refund or other remedy under applicable law, those statutory rights continue to apply irrespective of any app-store refund rules.
11. Price changes
Ness may change the price of Premium from time to time.
Any change affecting an existing automatically renewing subscription will be implemented in accordance with applicable law and the requirements of Apple, Google or another applicable payment platform.
Where notice or subscriber consent is required before a new price can apply, that process will be followed.
A price change will not retrospectively change the amount already paid for a completed subscription period.
12. Acceptable use
You must not:
- use Mezzo unlawfully or to access a system without authorisation;
- interfere with, disrupt or attempt to compromise the security or operation of Mezzo or associated systems;
- attempt to circumvent subscription, entitlement, usage-limit or security controls;
- use automated mechanisms to access the Service in a manner not authorised by Ness;
- reverse engineer, decompile or otherwise attempt to derive source code except to the extent such activity cannot lawfully be prohibited;
- use Mezzo in a way that materially affects the Service for other users; or
- use Mezzo to infringe the rights of Ness or another person.
Ness may take reasonable action to protect the Service, its users and associated systems where misuse or a security risk is detected.
13. Changes to the Service
Ness may modify, improve, replace, add or remove features of Mezzo from time to time.
This may include changes necessary for security, technical compatibility, regulatory compliance, third-party platform requirements or continued operation of the Service.
Ness may also change the features or limits applying to Free and Premium service levels.
Where a proposed change materially reduces the service provided during an already-paid subscription period, Ness will comply with applicable consumer law and any relevant app-store requirements and will provide notice where reasonably required.
Nothing in this section affects rights you have under laws that cannot lawfully be excluded.
14. Service availability
Ness aims to provide a reliable service but does not promise that Mezzo will operate continuously, without delay or without error.
The Service may occasionally be unavailable because of maintenance, software updates, internet or telecommunications failures, equipment faults, cyber-security events, third-party service failures, cloud-service failures or circumstances beyond Ness’s reasonable control.
Remote commands should not be assumed to have been successfully completed unless the system provides appropriate confirmation.
15. Intellectual property
Mezzo, including its software, design, text, graphics, logos, interfaces and other content, is owned by or licensed to Ness and is protected by applicable intellectual-property laws.
Subject to these Terms, Ness grants you a limited, personal, non-exclusive, non-transferable and revocable right to use Mezzo on supported devices for its intended purpose.
No ownership rights in Mezzo or Ness intellectual property are transferred to you.
16. Third-party services
Mezzo depends on or may interact with third-party products and services, including mobile operating systems, app stores, communications providers, cloud providers and notification services.
Ness does not control all aspects of those third-party services and cannot guarantee their continued availability or operation.
Your use of third-party services may also be subject to terms imposed by those third parties.
17. Privacy
Ness handles personal information in accordance with its Mezzo Privacy Policy, available through the application and the Mezzo support website.
The Privacy Policy explains the types of information Ness collects, how it is used and disclosed, and how you can access, correct or request deletion of personal information.
18. Account deletion
You may request deletion of your Mezzo account through the account controls provided in the application or through the account-deletion facility identified in our Privacy Policy or support website.
Deleting an account may result in permanent loss of account information, configurations and other information associated with the account, subject to information Ness is permitted or required to retain by law.
Account deletion and subscription cancellation are separate processes. Before deleting your account, you should separately cancel any active Apple or Google subscription if you do not want it to renew.
19. Suspension and termination
You may stop using Mezzo at any time.
Ness may suspend or terminate access where reasonably necessary because:
- you materially breach these Terms;
- your account or use of the Service creates a material security risk;
- Ness is required to do so by law;
- continued provision of the Service is prevented by a third-party platform or service on which it depends; or
- Ness discontinues the relevant Service.
Where reasonably practicable and appropriate, Ness will provide notice before terminating a Service.
Any discontinuation of a paid service remains subject to applicable consumer law and rights that cannot lawfully be excluded.
20. Australian Consumer Law
Our services come with guarantees that cannot be excluded under the Australian Consumer Law where that law applies.
Nothing in these Terms is intended to exclude, restrict or modify any guarantee, condition, warranty, right or remedy that cannot lawfully be excluded, restricted or modified.
Any limitation or exclusion in these Terms applies only to the maximum extent permitted by law.
21. Liability
To the extent permitted by law, Ness is not responsible for loss arising solely from circumstances outside its reasonable control, including failures of internet connectivity, mobile networks, third-party notification systems, app-store services, user equipment or other third-party infrastructure.
Ness is not responsible for a user’s failure to maintain suitable security monitoring or emergency-response arrangements where Mezzo has not been supplied as a professional monitoring or emergency-response service.
To the extent permitted by law, Ness will not be liable for indirect or consequential loss that was not reasonably foreseeable as a result of Ness’s breach.
Nothing in this section excludes or limits liability where doing so would be unlawful, including liability arising under rights or consumer guarantees that cannot lawfully be excluded.
22. Changes to these Terms
Ness may update these Terms from time to time to reflect changes to the Service, law, technology, security requirements or business operations.
Where a change materially affects your rights or an active paid subscription, Ness will provide notice where required by law or where reasonably appropriate.
The current version of the Terms will be made available through Mezzo or the Mezzo support website and will state its effective or last-updated date.
23. Governing law
These Terms are governed by the laws of New South Wales, Australia.
You and Ness submit to the courts of New South Wales and any courts competent to hear appeals from those courts, subject to any mandatory rights you may have under the laws of the jurisdiction in which you live.
Nothing in this section is intended to prevent a consumer from exercising rights available under applicable laws that cannot lawfully be excluded.
