End-User Licence Agreement

Off-the-Shelves Tech North Stars

Version 1.1 — effective 2026-08-17

This End-User Licence Agreement (the "Agreement") is a binding contract between you (the "Licensee") and AerelonTech Kft. (the "Provider"). It governs the Tech North Star package with which this file was distributed.

The sale and the licence are separate contracts with separate parties. The package is sold by Paddle (the "Reseller"), acting as merchant of record and authorised reseller: the Licensee buys the package from the Reseller, and the Reseller is responsible for payment, tax, invoicing and refunds. This Agreement is the licence, granted by the Provider, and the Provider delivers the package. Section 11 sets out which party the Licensee deals with about withdrawal and refunds.

By downloading, unzipping, opening or otherwise using the package, you accept this Agreement. If you do not accept it, do not download the package — you may withdraw from the purchase and obtain a full refund at any time before download, as set out in Section 11.

1. Definitions​

  • Materials — the entire contents of the package: the written documents, architecture decision records, user stories, diagrams (Mermaid, draw.io, exported images), skills, templates, scripts and any other file distributed as part of it, in every format supplied (Markdown, PDF, PPTX, ZIP).
  • Licensee — the single individual or single legal entity that purchased the licence, together with that entity's employees and contractors acting on its behalf.
  • Client — a third party to whom the Licensee supplies professional services (consulting, advisory, architecture, design, engineering, training or similar) for a fee.
  • Derivative — any adaptation of the Materials made by the Licensee: edited documents, redrawn diagrams, project-specific decision records, code or systems built by following the Materials.

2. Grant of licence​

Subject to payment in full and to the restrictions in this Agreement, the Provider grants the Licensee a perpetual, worldwide, non-exclusive, non-transferable, non-sublicensable (except as expressly permitted in Section 3) licence to:

a) use, read and store the Materials for the Licensee's own business or personal purposes;

b) make copies for the Licensee's internal use and for backup;

c) modify the Materials and create Derivatives;

d) build, operate and commercially exploit any software system, product or service developed with the help of the Materials — including one built with the assistance of AI tooling that the Licensee runs over the Materials.

The Licensee owns its Derivatives and everything it builds. This Agreement places no claim on the Licensee's own systems, code or revenue.

3. Professional-services rights (one layer of onward use)​

The Licensee may use the Materials in paid engagements and pass the results down exactly one level:

a) The Licensee may apply the Materials while delivering services to a Client, and may charge its normal fees for that work.

b) The Licensee may incorporate the Materials and Derivatives into the deliverables it hands to that Client, and may leave copies with the Client.

c) A Client that receives the Materials or a Derivative under (b) obtains a perpetual, non-exclusive, non-transferable licence to use them for the Client's own internal business purposes only, on the same terms and restrictions as this Agreement.

The chain of use stops with that Client. In particular:

d) The Client may not resell, redistribute, sublicense, rent, publish or otherwise commercially exploit the Materials or a Derivative as such, and may not pass them on to its own customers or to any further third party.

e) The Client obtains no right to use the Materials in its own paid engagements with third parties. A party that wishes to do so must purchase its own licence.

f) The Licensee is responsible for informing each Client of the restrictions in (d) and (e), and remains liable to the Provider for its Clients' compliance with them.

g) Nothing in (d) restricts the Client from building, operating and commercially exploiting its own systems, products or services, as set out in Section 2(d).

4. Restrictions​

The Licensee shall not, and shall not permit any third party to:

a) sell, resell, rent, lease, lend, sublicense or distribute the Materials or any Derivative as a standalone item, whether for a fee or free of charge, except as expressly permitted by Section 3;

b) publish the Materials or any substantially similar Derivative in a public repository, file-sharing service, website, forum, marketplace or other publicly accessible location;

c) offer the Materials or any substantially similar Derivative — under any name or branding — as a product, template collection, course, training programme, newsletter, subscription or knowledge base that competes with the Provider's offering;

d) use the Materials to train, fine-tune, evaluate or ground a machine-learning model, dataset, retrieval index or AI service that is made available to third parties, where doing so could reproduce or substitute for the Materials. Private use of AI tooling over the Materials for the Licensee's own projects and Client engagements is expressly permitted under Section 2(d);

e) share licence credentials, download links or licence keys outside the Licensee's organisation;

f) remove, obscure or alter any copyright notice, authorship attribution or this licence file from any copy of the Materials or of a Derivative that still substantially reproduces the Materials.

5. Intellectual property​

The Materials are licensed, not sold. All intellectual property rights in the Materials — copyright, database rights, trademarks, trade dress and know-how — remain the exclusive property of AerelonTech Kft. Nothing in this Agreement transfers ownership of the Materials to the Licensee or to any Client. All rights not expressly granted are reserved by the Provider.

The names "AerelonTech" and "Off-the-Shelf Tech North Star", and the Provider's logos, may not be used to endorse, brand or market the Licensee's or a Client's own products without the Provider's prior written consent. Naming the Provider factually — for example, stating that an engagement was based on a off-the-shelf Tech North Star package — is permitted.

6. Third-party materials​

The Materials reference and discuss third-party products, services and open-source projects (for example payment providers, cloud platforms and frameworks). The Provider is not affiliated with, endorsed by, or acting as a reseller of those parties. All third-party names and trademarks belong to their respective owners, and the Licensee's use of any third-party product is governed by that party's own terms and pricing.

7. Updates​

The licence covers the version of the Materials the Licensee has received and any updates the Provider chooses to supply. The Provider is under no obligation to produce updates, corrections or new versions, to keep any package available for download, or to keep the Materials current with changes in technology, vendors or regulation.

8. No warranty​

The Materials are provided "as is" and "as available", without warranty of any kind. To the fullest extent permitted by applicable law, the Provider disclaims all express, implied and statutory warranties, including any warranty of merchantability, fitness for a particular purpose, accuracy, completeness, non-infringement, and uninterrupted or error-free availability.

The Materials are reference architectures and worked examples. They are not legal, regulatory, tax, financial, accounting, security or professional advice, and they are not a certification of compliance with any standard, framework or regulation (including but not limited to GDPR, PCI DSS, PSD2, DORA or any banking, payments or data-protection regime). The Provider does not warrant that following the Materials will produce a system that is secure, compliant, performant, scalable, cost-effective or suitable for the Licensee's context.

The Licensee is solely responsible for reviewing the Materials, for adapting them to its own context, and for the design, implementation, security, testing, compliance and operation of any system it builds. Decisions taken from the Materials are the Licensee's own decisions.

9. Limitation of liability​

To the fullest extent permitted by applicable law:

a) the Provider shall not be liable for any indirect, incidental, special, consequential, punitive or exemplary damages, nor for loss of profit, revenue, business, goodwill, data, anticipated savings, or costs of procuring substitute goods or services, arising out of or in connection with the Materials or this Agreement, regardless of the legal theory and even if the Provider has been advised of the possibility of such damages;

b) the Provider's total aggregate liability arising out of or in connection with the Materials and this Agreement shall not exceed the amount actually paid by the Licensee for the licence to the package concerned;

c) the Provider shall have no liability whatsoever to any Client or other third party.

Nothing in this Agreement excludes or limits liability that cannot be excluded or limited under applicable law, including liability for death or personal injury caused by negligence, for wilful misconduct or gross negligence, or for fraud. Where the Licensee is a consumer, this Section does not affect the Licensee's mandatory statutory rights.

10. Term and termination​

This Agreement takes effect on the Licensee's first download or use of the Materials and continues indefinitely unless terminated.

The Provider may terminate this Agreement with immediate effect by written notice if the Licensee materially breaches it — in particular Sections 3 or 4 — and fails to remedy the breach within 14 days of notice, or where the breach is incapable of remedy.

On termination the Licensee shall cease all use of the Materials and delete or destroy all copies in its possession or control. Licences properly granted to Clients under Section 3 before termination survive, provided those Clients continue to comply with Sections 3(d), 3(e), 4 and 5. Sections 5, 6, 8, 9, 11 and 13 survive termination.

11. Right of withdrawal and refunds​

The Materials are digital content supplied without a tangible medium. Their entire value passes to the Licensee at the moment of download, and a download cannot be undone or returned. The refund position follows from that fact.

The Reseller is the counterparty to the sale. Withdrawal and refunds are therefore exercised against the Reseller, under the Reseller's terms, and any refund is paid by the Reseller. The Provider does not take the payment and cannot grant, refuse or pay a refund. This Section describes that position and records what the Provider does at download; it does not vary the Reseller's terms and is not capable of doing so.

11.1 Before download — full right of withdrawal​

Where the Licensee is a consumer, the Licensee has 14 days from the conclusion of the contract to withdraw without giving any reason, provided the package has not been downloaded, and is refunded the full price to the original means of payment. [1]

How to withdraw. Send an unambiguous statement of withdrawal to the Reseller, using the contact route on the purchase receipt. So that the purchase can be identified and the money returned to the right person, the Licensee is asked to:

a) send the notice from the same e-mail address that was used to place the order; and

b) state the full name of the package as it appears on the order — for example "Off-the-Shelves Tech North Stars — Small-scale — Sales funnel" — together with the order reference and the date of purchase.

No particular form is required, and a withdrawal that arrives within the 14 days is effective even if it omits some of the above. A notice naming no identifiable order will delay the refund until it can be matched, and further information may be requested for that purpose.

A notice sent to the Provider instead is not lost. The Provider will forward any withdrawal notice it receives to the Reseller and confirm to the Licensee that it has done so. The Licensee is nonetheless advised to notify the Reseller directly, as the Reseller decides and pays.

Express prior consent to the immediate commencement of performance, and acknowledgement that the right of withdrawal is thereby lost, are given to the Reseller at checkout as part of the contract of sale.

Immediately before the download begins, the Provider additionally displays that position to the Licensee and requires confirmation of it: that supply of the named package is beginning now, and that the right of withdrawal ends once the download has begun. The download starts only once that confirmation has been given. The Provider records the exact wording displayed, its version, and the moment of confirmation, as set out in Section 11.5.

Once the download has begun, the right of withdrawal is extinguished and the price is non-refundable, in accordance with § 29 (1) m) of Government Decree 45/2014. (II. 26.) Korm. of Hungary, implementing Article 16(m) of Directive 2011/83/EU. [1]

Where no such consent and acknowledgement were obtained before the download, the 14-day right of withdrawal under Section 11.1 remains available to the consumer notwithstanding the download.

11.3 Discretionary refunds after download​

A refund after download is a goodwill gesture, granted or refused by the Reseller at the Reseller's sole discretion. It is an exception decided case by case, not an entitlement, and not a precedent for any other request or any other Licensee.

The Provider will support such a request:

a) only where the Licensee has not exercised the professional-services rights in Section 3 in respect of that package — that is, where no copy has been passed to a Client; and

b) only on the Licensee confirming in writing that all copies of the Materials and of any Derivative have been deleted or destroyed.

Where a refund is paid after download, the licence granted under Section 2 terminates on payment, from which point Section 10 applies as on termination. This applies however the refund arose, including where the Reseller grants one that the Provider did not support.

Requests should be sent to the Reseller, stating the order reference and the reason. The Licensee may copy the Provider at the contact address above.

11.4 Statutory conformity rights are unaffected​

Sections 11.2 and 11.3 concern the right of withdrawal only. They do not affect and do not limit the Licensee's mandatory statutory rights where the Materials are not as described or otherwise fail to conform to the contract, including the remedies available to consumers under Directive (EU) 2019/770 and the Hungarian legislation implementing it. [2] A Licensee who did not receive the package, received the wrong package, or received a package materially different from its description remains entitled to the remedies the law provides, regardless of download.

Those remedies may be raised with either the Reseller or the Provider. The Provider asks to be contacted first where the complaint concerns the Materials themselves, since the Provider made them and can usually remedy the problem directly and faster than a refund would resolve it. That request does not restrict the Licensee's right to proceed against the Reseller.

11.5 Records of download​

The Provider records, for each order: the identity of the Licensee, the order reference, the wording and version of the confirmation presented under Section 11.2, the time at which it was given, and the time, source address and completion of each download of the package, together with the version and content hash of the file served.

The parties agree that these records may be relied on as evidence that the package was made available and downloaded, and that the confirmation under Section 11.2 was obtained. The Provider retains them for as long as necessary to establish, exercise or defend legal claims, and processes them on that basis under Article 6(1)(f) of the GDPR.

These records may be disclosed to the Reseller where they are relevant to a refund request, a payment dispute or a chargeback concerning the Licensee's order — that being the purpose for which the Provider keeps them, and the only way the Reseller can establish whether supply had begun. On request, the Provider will supply the Licensee with the records relating to that Licensee's own orders.

12. Support​

Support, if any, is provided at the Provider's discretion via the contact address above. The Provider does not commit to any response time, to answering questions about the Licensee's own systems, or to reviewing the Licensee's adaptations of the Materials.

13. General​

a) Governing law. This Agreement is governed by the laws of Hungary, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods.

b) Jurisdiction. The courts of Budapest, Hungary have exclusive jurisdiction over any dispute arising out of this Agreement, save where mandatory consumer law grants the Licensee the right to bring proceedings in another forum.

c) Assignment. The Licensee may not assign or transfer this Agreement or the licence without the Provider's prior written consent, except as part of a transfer of the Licensee's entire business, on notice to the Provider. The Provider may assign this Agreement to a successor in its business.

d) Entire agreement. This Agreement is the entire agreement between the parties regarding the Materials and supersedes any prior understanding on the subject.

e) Severability. If any provision is found unenforceable, it shall be modified to the minimum extent necessary to make it enforceable, and the remaining provisions stay in full force.

f) No waiver. A failure to enforce any provision is not a waiver of the right to enforce it later.

g) Language. This English text is the governing version of the Agreement. Any translation is provided for convenience only.
