PLEASE READ THIS DISCLAIMER CAREFULLY. By using Trefnus CMMS, you acknowledge and agree to all terms set forth below. This disclaimer supplements and forms part of the Terms of Service.

1. General Disclaimer

Trefnus CMMS (the "Application") is a computerised maintenance management tool designed to assist users in organising and tracking maintenance activities. The Application is provided strictly as an informational and organisational aid.

The Application does not provide professional engineering advice, safety assessments, regulatory compliance guidance, or any form of professional consultation.

2. No Professional Advice

Nothing in the Application constitutes:

Professional engineering, mechanical, electrical, or safety advice;
Certified maintenance planning or scheduling;
Regulatory or legal compliance advice;
Health and safety assessments or risk evaluations;
Insurance, financial, or legal advice;
A substitute for qualified professional inspection, assessment, or certification.

Users should always consult qualified professionals for maintenance decisions, safety-critical tasks, and regulatory compliance matters.

3. No Guarantee of Accuracy

The Application relies entirely on data entered by users. We make no representations or warranties regarding:

The accuracy, completeness, or reliability of any data stored in the Application;
The correctness of any maintenance schedules, intervals, or reminders;
The suitability of any maintenance procedures or checklists;
The accuracy of any reports generated by the Application.

All data output is only as accurate as the data input. "Garbage in, garbage out" applies fully.

YOU MUST NOT rely solely on this Application for safety-critical maintenance scheduling or tracking. Independent safety management systems, qualified personnel, and regulatory frameworks must always be used.

5. Statutory and Regulatory Compliance

The Application may include features for tracking statutory testing and regulatory compliance dates. However:

The Application does not guarantee compliance with any law, regulation, standard, or code of practice;
Compliance reminders are based solely on user-entered data and may be incomplete or incorrect;
Users are solely responsible for ensuring compliance with all applicable regulations;
The Application does not replace mandatory inspection regimes, statutory examination schemes, or certified compliance programmes;
Failure of the Application to send reminders or alerts does not relieve you of any regulatory obligations.

Clearing browser data or cache;
Uninstalling the Application or removing it from your device;
Device failure, theft, or loss;
Browser updates or changes;
Operating system updates or reinstallation;
Corruption of browser storage;
Any other cause beyond our control.

YOU ARE SOLELY RESPONSIBLE FOR MAINTAINING ADEQUATE BACKUPS OF ALL DATA. WE SHALL HAVE NO LIABILITY WHATSOEVER FOR ANY DATA LOSS.

7. Equipment and Asset Disclaimer

The Application may be used to track maintenance of equipment, machinery, and assets. We expressly disclaim any responsibility for:

Equipment failure, breakdown, or malfunction;
Damage to property arising from maintenance performed or not performed;
Personal injury resulting from equipment use, maintenance, or failure;
Loss of production, downtime, or business interruption;
Any consequences arising from reliance on data stored in the Application;
Incorrect or missed maintenance schedules;
Costs of repair, replacement, or remediation.

8. Offline Functionality Disclaimer

The Application offers offline functionality through service worker technology. While offline:

Licence verification cannot occur, and access is granted based on cached credentials;
Some features may not function correctly;
Data entered offline is stored locally and is not backed up;
We cannot guarantee the reliability or completeness of offline functionality.

The availability or uptime of third-party services;
Security breaches or data loss at third-party providers;
Changes to third-party services that may affect the Application;

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW:
