Terms of Service

1. About these terms

These Terms of Service (the "Terms") are issued by The RLK Group, a private limited company incorporated in Scotland under company number SC781391, with its registered office at Unit 4 Strathclyde Business Centre, Cambuslang, United Kingdom, G72 7XR ("RLK", "we", "us"). They govern access to and use of UAVSimNet, our counter-UAS mission analysis platform (the "Platform"), and any related services we provide (together, the "Services").

These Terms apply to any party that submits an access request, accepts an invite link, authenticates to the Platform, or otherwise uses the Services (the "Customer", "you"). Acceptance is recorded at access-request time through the four consent checkboxes on our public access-request form, with a timestamp stored against the submission. Using the Services after the Effective Date shown above constitutes continuing acceptance of the Terms in force.

2. Definitions

• Customer — the organisation on whose behalf an access request was approved and a tenant provisioned.
• Authorised User — an individual employee, contractor, or agent of the Customer who holds credentials issued by RLK to access the Platform on Customer's behalf.
• Platform — UAVSimNet, including its web application, public site, operator console, simulation engine, documentation, and any supporting infrastructure.
• Services — access to the Platform and any support, consultancy, or professional services RLK agrees in writing to provide.
• Customer Data — scenarios, parameter sets, threat profiles, run inputs, run outputs, and any other content the Customer or its Authorised Users generate, upload, or produce using the Platform.
• Confidential Information — information disclosed by one party to the other that is marked as confidential or that, by its nature, a reasonable person would treat as confidential.
• Subscription Term — the period for which Customer holds a paid entitlement to the Services, as recorded in the applicable order form.
• Effective Date — the date shown in the banner at the top of this document, or the date Customer first accepts these Terms, whichever is later.

3. Access and accounts

Access to the Platform is enterprise-only. RLK provisions tenants manually after reviewing each access request against our eligibility, compliance, and export-control policies. We may decline any access request at our sole discretion. There is one tenant per Customer; if additional tenants are required (for example, for separate programmes or deployment regions), they are agreed in writing and priced separately.

Authorised Users receive access via single-use invite tokens that expire once consumed or after a defined window. Each Authorised User must set their own password at invite consumption and must not share credentials with any other individual. Customer is responsible for keeping passwords confidential, for promptly revoking access when a user leaves, and for all activity conducted under credentials issued to it. We may suspend or revoke access where we reasonably believe credentials have been compromised, shared, or misused.

4. Subscription, term, and renewal

The Services are provided on an annual enterprise-subscription basis. Commercial terms — including price, Subscription Term, renewal dates, cancellation notice, and any usage limits — are agreed in writing during onboarding and recorded in an order form or equivalent commercial document signed by both parties. We do not list pricing publicly.

On expiry of the Subscription Term, access to the Platform is automatically suspended unless the subscription has been renewed by mutual written agreement. Renewal is not automatic. Customer remains responsible for exporting any Customer Data it wishes to retain before expiry; post-expiry retrieval is subject to §13 (Term and termination). Prepaid fees are not refundable if Customer terminates for convenience before the end of a Subscription Term.

5. Acceptable use

Customer's use of the Services is subject to our Acceptable Use Policy (the "AUP"), available at /aup, which is incorporated into these Terms by reference. Breach of the AUP is a material breach of these Terms. RLK may suspend access to the Services immediately, without prior notice, where we reasonably believe continued access would cause serious harm to the Platform, to other customers, or to the public interest.

6. Customer Data

As between the parties, Customer owns all right, title, and interest in Customer Data. RLK claims no ownership over scenarios, parameter sets, threat profiles, or run results produced by Customer. Customer grants RLK a limited, non-exclusive, worldwide, royalty-free licence to host, store, process, transmit, and display Customer Data strictly as necessary to provide the Services, to respond to Customer's support requests, and — only where Customer has given separate consent through the access-request form — to use anonymised artefacts for the purpose described in §7.

Our handling of personal data within Customer Data is described in our Privacy Policy at /privacy. Customer warrants that it has the necessary rights, authorisations, and lawful bases to upload Customer Data to the Platform and to permit RLK to process it as described in these Terms.

7. Training data participation

Where Customer has opted in to the training-data mirror at access-request time, RLK may duplicate a defined set of anonymised artefacts from each successful run into an internal training mirror used to improve future releases of the Platform. Only a hashed tenant identifier is written alongside the artefact files; direct personal identifiers are stripped before the data enters the mirror. Customer may withdraw from the training mirror at any time by giving written notice to RLK at the registered office address in §20; withdrawal applies to future runs only and does not retroactively delete mirror entries already created, although Customer may request such deletion as described in the Privacy Policy.

8. Confidentiality

Each party agrees (a) to use the other's Confidential Information only as reasonably necessary to perform these Terms, (b) to protect it with at least the degree of care it applies to its own confidential information of similar importance, and (c) not to disclose it to any third party without the discloser's prior written consent, except to employees, contractors, advisers, or sub-processors bound by confidentiality obligations at least as protective as those in these Terms. The obligations in this clause do not apply to information that is or becomes publicly known without fault of the receiver, was known to the receiver without restriction before disclosure, is independently developed without reference to the Confidential Information, or is required to be disclosed by law or court order (in which case the receiver shall, where lawful, give the discloser reasonable notice and cooperate in seeking confidential treatment). This clause survives termination of these Terms for a period of five (5) years.

9. Intellectual property

RLK retains all right, title, and interest in and to the Platform, including all software, models, simulation engines, pre-loaded demonstrations, documentation, visual design, and any improvements, modifications, or derivative works thereof. No rights or licences are granted to Customer other than as expressly set out in these Terms. Customer shall not (and shall not permit any Authorised User or third party to) reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code, model weights, training data, or non-public interfaces of the Platform, nor create derivative works of the Platform, except as expressly permitted by mandatory law.

If Customer provides feedback, suggestions, or improvement ideas in connection with the Services, RLK may use and incorporate that feedback into the Platform without obligation, payment, or attribution.

10. Compliance and export control

Counter-UAS analytic software is dual-use technology and may be subject to export controls under UK Strategic Export Controls (administered through SPIRE), the EU dual-use regulation, the United States International Traffic in Arms Regulations (ITAR) and Export Administration Regulations (EAR), and equivalent regimes in Customer's jurisdiction.

Customer is solely responsible for compliance with all export-control and sanctions laws applicable to its use of the Services. Customer warrants at access-request time, and re-confirms on each login, that: (a) it is not located in, organised under the laws of, or resident in a country subject to comprehensive sanctions; (b) it is not on, and is not owned or controlled by any party on, a prohibited persons list maintained by the United Kingdom, the European Union, the United Nations, the United States, or any other applicable authority; and (c) it will not make the Services or any output of the Services available to any such party. RLK reserves the right to suspend or terminate access immediately, without notice, where it reasonably believes continued provision of the Services would breach these controls.

11. Warranties and disclaimers

Each party warrants that it has full corporate authority to enter into and perform these Terms. Save as expressly set out in these Terms, and to the fullest extent permitted by law, RLK provides the Services "as is" and "as available", without warranty or representation of any kind, whether express, implied, statutory, or otherwise, including any implied warranty of merchantability, satisfactory quality, fitness for a particular purpose, accuracy, or non-infringement.

UAVSimNet is a simulation and analysis platform. RLK does not warrant that simulation results will accurately predict the outcome of any real-world engagement, and simulation outputs are intended to inform engineering and operational judgement, not to replace it. All defence, procurement, and operational decisions remain solely Customer's responsibility. RLK does not guarantee fitness of the Services for any specific operational deployment, mission, or real-time fire-control use.

12. Limitation of liability

To the fullest extent permitted by Scottish law, RLK's aggregate liability to Customer arising out of or in connection with these Terms, whether in contract, delict (tort), negligence, breach of statutory duty, or otherwise, is capped at the total fees paid by Customer to RLK for the Services in the twelve (12) months immediately preceding the event giving rise to the claim.

In no event shall RLK be liable for any indirect, consequential, special, exemplary, or punitive damages, nor for any loss of profits, revenue, business, anticipated savings, goodwill, or data, arising out of or in connection with these Terms, even if RLK has been advised of the possibility of such damages. Nothing in these Terms excludes or limits liability for fraud or fraudulent misrepresentation, for death or personal injury caused by a party's negligence, or for any other liability that cannot lawfully be excluded or limited under Scottish law.

13. Term and termination

These Terms take effect on the Effective Date and continue for the Subscription Term, unless terminated earlier under this clause. Either party may terminate these Terms with immediate effect on written notice if the other party commits a material breach that is incapable of remedy, or that it fails to remedy within thirty (30) days of receiving written notice requiring it to do so, or becomes insolvent, enters administration, ceases trading, or suffers an analogous event in its jurisdiction.

RLK may terminate these Terms with immediate effect where Customer materially breaches the AUP, fails to comply with §10 (Compliance and export control), fails to pay undisputed fees, or where termination is required by law.

On termination, all rights of access cease. Customer may request an export of its Customer Data within thirty (30) days of the effective date of termination; after that window, Customer Data is deleted, except that (a) anonymised training-mirror entries are retained unless separately deleted under the Privacy Policy, and (b) audit logs and commercial records are retained for the periods set out in the Privacy Policy and as required by law. Clauses intended by their nature to survive termination — including §6, §8, §9, §10, §11, §12, §13, §18, and §19 — survive.

14. Suspension

RLK may suspend Customer's access to the Services, in whole or in part, where: (a) Customer has failed to pay undisputed fees when due; (b) RLK reasonably believes Customer has breached the AUP or §10; (c) a security incident requires containment; or (d) RLK is required to do so by law or regulatory compulsion. We will give Customer reasonable notice of suspension where it is practicable and lawful to do so; in urgent circumstances, we may suspend immediately and notify Customer as soon as reasonably practicable.

15. Force majeure

Neither party is liable for any failure or delay in performing its obligations under these Terms (other than payment) to the extent caused by events beyond its reasonable control, including acts of God, war, terrorism, civil disturbance, pandemic, strike, cyber-attack, infrastructure failure, or action of a competent authority. The affected party shall notify the other promptly and use reasonable endeavours to mitigate the effect.

16. Notices

Written notices to The RLK Group shall be sent in writing to its registered office at Unit 4 Strathclyde Business Centre, Cambuslang, United Kingdom, G72 7XR, or to such other address as The RLK Group may notify in writing from time to time. Such notices are deemed received on the second business day after posting by first-class recorded delivery. Written notices to Customer shall be sent to the email address on the Customer's account record and are deemed received on the next business day after transmission, unless a delivery-failure notification is received.

17. Assignment

Customer may not assign, novate, sub-licence, or otherwise transfer these Terms or any rights or obligations under them without RLK's prior written consent. RLK may assign or novate these Terms to a successor in business or to a corporate affiliate without Customer's consent, provided the successor assumes the obligations on materially equivalent terms.

18. Governing law and jurisdiction

These Terms and any non-contractual obligations arising out of or in connection with them are governed by Scottish law. The parties submit to the exclusive jurisdiction of the Court of Session, Edinburgh, Scotland, for any dispute arising out of or in connection with these Terms, save that RLK may seek injunctive or interdict relief in any court of competent jurisdiction to protect its Confidential Information or intellectual property.

19. Entire agreement

These Terms, together with the AUP, the Privacy Policy, and any executed order form or statement of work, constitute the entire agreement between the parties in relation to the Services, and supersede all prior or contemporaneous communications, proposals, and understandings. No modification to these Terms is effective unless made in writing and signed by an authorised representative of each party. If any provision is held unenforceable by a court of competent jurisdiction, the remaining provisions remain in full force and effect, and the unenforceable provision shall be modified to the minimum extent necessary to make it enforceable while preserving its original intent.

20. Contact

Legal notices, termination notices, and all other formal correspondence under these Terms shall be sent in writing to The RLK Group at its registered office, or to such other address as The RLK Group may notify in writing from time to time:
