You are solely responsible for the decisions you make based on information shown by or stored in the Application.
Trefnus Resource (the “Application”) is provided strictly on an “AS IS” and “AS AVAILABLE” basis. To the maximum extent permitted by applicable law, we make no representations or warranties of any kind, express or implied, regarding the Application, its content, its accuracy, its availability, its security, its fitness for any particular purpose, or any results obtained from its use.
The Application is general-purpose scheduling and booking software. Nothing in or produced by the Application constitutes professional advice of any kind. In particular, the Application does not provide and is not a substitute for:
You must seek qualified independent advice before acting on any output produced by, or any decision based on, the Application.
The Application processes data that you enter. The accuracy, completeness, lawfulness and currency of that data is your sole responsibility. We do not verify, validate, sanitise or correct your input. We do not warrant that calculations, summaries, schedules, availability indicators, conflict warnings, dashboards, statistics, occupancy figures or any other outputs are accurate, correct or complete. You must independently verify all outputs before relying on them.
If you use Trefnus Resource for any of the activities below, you do so entirely at your own risk and on the express understanding that we accept no responsibility for the consequences.
The Application is not a Property Management System (PMS), is not connected to any booking channel or Online Travel Agency (OTA), does not perform real-time inventory synchronisation, and does not enforce double-booking prevention against external systems. Indicators and warnings shown in the Application reflect only data entered locally. We disclaim all liability for lost bookings, over-bookings, double bookings, guest disputes, refund claims, lost revenue, reputational damage and regulatory fines arising from your use of the Application.
The Application does not track condition, certification, calibration, insurance, roadworthiness, MOT/test status, statutory inspection compliance or operator competency. It is not a substitute for any inspection or compliance regime. You are solely responsible for ensuring that any asset is safe and lawful to release for use.
The Application is not a clinical system. It is not certified as a medical device under the UK Medical Devices Regulations 2002, the EU Medical Device Regulation (Regulation (EU) 2017/745), the US FDA framework or any equivalent. It must not be used to schedule clinical interventions, manage patient data, support clinical decisions or be relied on where a failure could affect patient safety.
The Application is not designed, intended or licensed for use in environments where failure, delay, inaccuracy or downtime could result in death, personal injury, environmental damage, or significant financial or operational harm (including without limitation aviation, nuclear, emergency services, life-support, hazardous materials, defence or critical national infrastructure).
Use of the Application does not guarantee compliance with any law, regulation, standard, code of practice or industry framework, including without limitation GDPR, the UK Data Protection Act 2018, the Equality Act 2010, the Consumer Rights Act 2015, fire safety regulations, health and safety legislation, accessibility standards, anti-money-laundering rules, or any tax or accounting requirement. Compliance is your sole responsibility.
ALL OF YOUR APPLICATION DATA IS STORED LOCALLY ON YOUR DEVICE. We do not back up your data. We cannot recover data that is lost from your Device.
Local browser storage (IndexedDB, localStorage, Service Worker cache) can be cleared, evicted or corrupted at any time and for many reasons, including: clearing browsing data; browser updates; operating system updates; storage quota limits; private/incognito mode; third-party browser extensions; antivirus or cleanup utilities; device failure; disk corruption; malware; switching browsers or devices; or our own software updates and migrations. You are responsible for taking regular exports/backups and storing them safely in independent locations. We disclaim all liability for any loss, corruption, alteration or unrecoverability of your data.
Where the Application is used in connection with physical resources (rooms, units, vehicles, tools, plant, equipment, pitches, courts, beds, etc.), the existence of a booking record in the Application does not authorise any person to access, use, occupy, operate or take possession of any physical resource. All authorisations, handovers, key issue, safety briefings, insurance checks, deposit handling, contractual paperwork and supervision remain entirely your responsibility. We accept no liability for damage to, loss of, theft from or misuse of any physical asset; nor for injury to any person; nor for any dispute between you and any guest, hirer, employee, contractor or visitor.
The Application is a Progressive Web App. Some functionality is designed to work offline by serving cached files from a Service Worker. Offline functionality is provided on a strict best-effort basis and is not guaranteed. Cached content may be out of date. Licence verification requires connectivity (a bounded transient grace window may apply on previously activated Devices). Behaviour offline depends on browser, operating system, storage availability and Service Worker state, all of which are outside our control.
The Application depends on third-party services including Supabase (authentication and database), the unpkg content delivery network and the jsDelivr content delivery network (for React, Babel, PDF.js and the Supabase JavaScript client). We do not control those services. Their unavailability, modification, deprecation, security incidents or business decisions may impair or prevent your use of the Application. We disclaim all liability arising from third-party service behaviour.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, OUR TOTAL CUMULATIVE LIABILITY FROM ALL CAUSES AND ALL THEORIES OF LIABILITY SHALL NOT EXCEED THE GREATER OF (A) THE FEES YOU PAID US FOR THE APPLICATION IN THE 12 MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED POUNDS STERLING (£100).
We exclude all liability for indirect, incidental, special, consequential, exemplary and punitive damages; loss of profit, revenue, business, goodwill, opportunity, anticipated savings or contracts; loss or corruption of data; business interruption; substitute services; and any loss or damage arising from any operational decision taken in reliance on the Application. See clause 14 of the Terms of Service for the full limitation of liability, which applies in conjunction with this Disclaimer.
You expressly assume all risk arising out of or in connection with your use of the Application, including without limitation the risks that the Application may be unavailable, defective, inaccurate, lose your data, fail to send a magic-link email, fail to verify your licence, deny access to your account, or produce unexpected results. If you are unwilling to accept any of these risks, you must not use the Application.
The Application does not provide, include or substitute for any form of insurance. You are solely responsible for arranging and maintaining appropriate insurance cover (including public liability, professional indemnity, business interruption, cyber and data-loss cover) for your operations.
References within the Application or its documentation to any third-party product, service, organisation or person do not constitute or imply endorsement, sponsorship or recommendation by us, and vice versa.
