Terms of Use

These Terms of Use (the "Terms") form a binding agreement between the operator of Groundmaster AI (the Groundmaster project, "we", "us") and the person or entity accessing the Platform. By creating or being issued an account, accessing the website or application, submitting data, or otherwise using the Platform, you confirm that you have read, understood and accept these Terms and the documents referenced in them. If you do not accept them in full, you must not use the Platform.

Where you use the Platform on behalf of an organisation, you represent that you are authorised to bind that organisation, and "you" means both you and that organisation. Where a separate written agreement, order form or subscription agreement has been signed, that agreement prevails over these Terms to the extent of any conflict.

In these Terms and in the other documents of the Legal & Trust Center:

• Groundmaster / Groundmaster AI — the software service described in these Terms and its operator.

• Third-Party Services — services not operated by us that are used to deliver the Platform or that you choose to connect to it.
• Documentation — guidance we publish describing the use of the Platform.
• Subscription — the agreed right to access the Platform for a term and scope.
• Account — the credentials and profile through which a User accesses the Platform.
• Confidential Information — non-public information disclosed by one party to the other in connection with the Platform.

The Platform is:

• a software platform delivered as a cloud service (SaaS);
• an information-management system for maintenance, engineering, stores and quality workflows;
• a workflow-support and decision-support system;
• an AI-assisted platform, where AI features produce non-binding suggestions;
• a multi-organisation system in which each Organisation's data is logically separated.

The Platform is not, and must not be represented or relied upon as, any of the following:

• an aviation authority, a competent authority, or a national or European aviation regulator;
• an approved maintenance organisation, a continuing airworthiness management organisation, a combined airworthiness organisation, a design organisation or a production organisation;
• a certification body, a maintenance certifying organisation or an airworthiness review organisation;
• a substitute for licensed engineers, certifying staff, quality personnel or safety management personnel;
• a substitute for regulatory approval, an approved organisation's own procedures, or an approved exposition or manual;
• a substitute for approved maintenance data, aircraft or component maintenance manuals, structural repair manuals, approved engineering instructions, airworthiness directives, service bulletins or applicable regulations;
• a source of legal, regulatory or engineering authority.

Use of the Platform does not, by itself, establish or demonstrate compliance with any aviation regulation, approval requirement or organisational requirement. Compliance is achieved and demonstrated by the Customer's organisation through its own approvals, procedures, personnel and records.

The Platform may assist in organising, retrieving, analysing and managing information. The Customer and its authorised personnel nevertheless remain solely responsible for, among other things: maintenance decisions; airworthiness determinations; maintenance release and certificate-of-release decisions; inspection decisions; defect classification and deferral decisions; the application of minimum equipment and configuration deviation provisions; directive and bulletin assessment and compliance; maintenance programme compliance; component eligibility and configuration control; the selection and use of approved data; engineering, safety and quality decisions; personnel authorisations; and continuing airworthiness management.

Output generated or organised by the Platform, including automated or AI-assisted output, must never be treated as an approved instruction, an approved data source, or a certification decision. It requires verification by an appropriately authorised human before any operational use.

Access is granted through named accounts. Accounts are personal and must not be shared. Each Customer is responsible for the configuration of its Organisation, including which individuals receive access, the roles and permission levels assigned to them, the accuracy of personnel attributes recorded in the Platform, and the timely removal or suspension of access when it is no longer required.

You must keep credentials confidential, use appropriate authentication controls, and notify us without undue delay if you suspect unauthorised access. Activity carried out through an account is attributed to that account and to the Organisation it belongs to.

Subject to these Terms and to a valid Subscription, you receive a non-exclusive, non-transferable, revocable right to access and use the Platform for your internal business purposes. The Acceptable Use Policy forms part of these Terms and sets out prohibited conduct, including attempts to circumvent authentication, permissions, tenancy separation or rate limits, and use of the Platform as a substitute for approved data or authorised personnel.

Customer Data remains the property of the Customer or its licensors. We claim no ownership of it. You grant us only the rights necessary to host, process, transmit, back up, secure, display and otherwise operate the Platform for you, and to provide support and comply with law.

You are responsible for ensuring you have the rights necessary to submit Content, for its accuracy and completeness, for classifying sensitive material appropriately, and for not uploading material you are not permitted to disclose.

Where AI features are available, they operate as decision support only. AI output may be incomplete, inaccurate, outdated, misinterpreted, fabricated, misclassified, or may omit relevant information. It must be validated by an appropriately authorised human before use. AI features never issue approvals, certifications or releases, and do not silently execute safety-relevant actions. Further detail is set out in the AI Policy & AI Transparency Notice.

The Platform relies on infrastructure and service providers, and may allow you to connect services you choose. Categories of providers are listed in the Subprocessors document. Third-party services are governed by their own terms; we are not responsible for their acts or omissions beyond our obligations as described in the Data Processing Terms.

We aim to provide the Platform continuously but do not warrant uninterrupted availability. We may modify, add or remove functionality, and may perform planned or emergency maintenance. Support arrangements, response targets and maintenance windows are described in the Service Levels & Support document. Where a change materially reduces core functionality, we will give reasonable notice where practicable.

We may suspend access where there is a material security risk, unlawful use, a serious breach of these Terms, non-payment, or a legal requirement to do so. Suspension will be proportionate and, where practicable, preceded by notice.

On termination, access ceases and data is handled as described in the Data Retention & Deletion Policy and the Data Export & Portability Policy. You are responsible for exporting the records your organisation is required to retain before the end of any post-termination export window.

Each party will protect the other's Confidential Information with at least reasonable care, use it only for the purposes of the Platform, and disclose it only to personnel and subprocessors bound by confidentiality obligations, or where required by law.

The Platform is provided on an "as is" and "as available" basis. To the maximum extent permitted by law we disclaim all implied warranties, including fitness for a particular purpose, non-infringement and uninterrupted or error-free operation. We do not warrant that the Platform, its content organisation, its forecasts, its alerts or its AI output are complete, accurate, current or suitable for any regulatory, engineering, airworthiness or safety purpose.

To the maximum extent permitted by law, neither party is liable for indirect, incidental, special, consequential or punitive damages, or for loss of profit, revenue, goodwill, anticipated savings, or data beyond our restoration obligations. Our aggregate liability arising out of or relating to the Platform is limited to the amounts paid or payable for the Platform in the twelve months preceding the event giving rise to the claim.

Nothing in these Terms limits liability that cannot be limited by law, including liability for death or personal injury caused by negligence, for fraud, or for wilful misconduct. Because the Platform is a decision-support system, we are not liable for maintenance, airworthiness, certification, operational or regulatory decisions taken by you or your personnel.

You will indemnify us against third-party claims arising from your Content, your use of the Platform in breach of these Terms or applicable law, or your reliance on Platform output without the verification required by these Terms.

These Terms are governed by the laws of Portugal, together with applicable European Union law, and the courts of the competent courts of Portugal have exclusive jurisdiction, without prejudice to mandatory consumer or statutory protections. Applicable jurisdiction for the Legal & Trust Center as a whole is Portugal, European Union.

We may update these Terms. The version, effective date and last-updated date are shown at the top of this page, and material changes are announced in advance where required. Continued use after the effective date constitutes acceptance of the updated version.

If any provision is held invalid, the remainder continues in force. Failure to enforce a right is not a waiver. You may not assign these Terms without our consent; we may assign to an affiliate or successor. These Terms, together with the documents of the Legal & Trust Center referenced in them, form the entire agreement regarding the Platform in the absence of a separate signed agreement.
