Terms of Service

Version 1.0 — effective 2026-10-07

These Terms govern your use of technorthstars.hu (the "Site") and any purchase you make through it. By using the Site or placing an order you accept them.

Who you buy from

Purchases are sold by Onelink, Stripe's merchant-of-record service, which acts as the merchant of record — the seller and the party you contract with for the sale, and the party responsible for payment, tax and refunds. We license the package to you. Section 2 explains the split, and Sections 4, 5 and 7 follow from it.

Your order will show as "Sold through Onelink", and the charge appears on your card statement as LINK.COM* followed by our descriptor rather than under our name.

Seller of record. The Stripe company you contract with depends on where you are, and Stripe publishes the current list at onelink.com/terms/contracting-entity. At the date of this version:

  • Buyers outside the Americas — including the European Economic Area and Hungary — contract with Stripe Technology Company, Limited, an Irish limited company.
  • Buyers in North, Central and South America except Brazil contract with Stripe, LLC, a US limited liability company.
  • Buyers in Brazil contract with Stripe Brasil Soluções de Pagamento - Instituição de Pagamento Ltda.

We link to Stripe's own list rather than reprinting registration numbers here, because that list is the authoritative one and it can change without us noticing.

1. Who we are​

AerelonTech Kft. (the "Provider", "we", "us")

  • 1023 Budapest, Árpád Fejedelem útja 26-28, 5. floor, Hungary
  • Company registration number: 01-09-458461
  • EU VAT number: HU33087867
  • E-mail: sandor@aerelontech.hu

We are registered with the Court of Registration of the Budapest-Capital Regional Court. There is no separate code of conduct we are bound by.

2. What we sell​

The Site sells digital products — architecture packages ("Tech North Stars") delivered as downloadable files. They are digital content supplied without a tangible medium. Nothing is shipped physically.

Each package is licensed, not sold. The licence terms are set out in the End-User Licence Agreement ("EULA"), which you can read in full before buying and which is also included in every package.

Two agreements, two parties. This is worth understanding because it decides who you deal with about what:

BetweenGoverned by
The sale — payment, tax, invoice, refundYou and OnelinkOnelink's Terms of Service and its refund process
The licence — what you may do with the materialsYou and usThe EULA
Delivery — the download itselfPerformed by us, under the licenceThese Terms, Section 6

Onelink is the seller of the package. You buy the package from Onelink; we license it to you and deliver it. Where these Terms and the EULA conflict on licence scope, the EULA prevails. Where either conflicts with Onelink's own terms on the sale, Onelink's terms govern the sale — we cannot vary them, and nothing here is intended to.

3. Accounts​

You need an account to purchase and to download. Accounts are created through Google sign-in (Firebase Authentication). You must:

  • be at least 18 years old and legally able to enter a contract;
  • provide accurate information and keep your sign-in credentials secure;
  • not share your account or your download links with anyone else.

You are responsible for everything done through your account. We may suspend or close an account that is used to breach these Terms or the EULA.

4. Orders, prices and tax​

The price shown is the price you pay. Prices are displayed inclusive of any applicable VAT or sales tax. No tax is added at the end.

⚠️ The price on our pages is quoted in our catalogue currency, and the payment page may show you a different one. Onelink converts the price into your own currency at checkout, from where you are, and settles the tax for your jurisdiction there. The figure on the payment page, shown before you confirm, is the one that is charged.

The sale contract is concluded with Onelink when your payment is confirmed. We then make the package available for download and send you a delivery e-mail with the link.

Tax is determined and charged by Onelink, as merchant of record, based on the billing address you give at checkout. Depending on where you are, that may be Hungarian VAT, the VAT of your own EU country, a reverse-charge treatment if you supply a valid business VAT number, or a non-EU sales tax or GST. Which of these applies, and at what rate, is Stripe's determination and is shown to you before you pay.

Onelink issues the invoice or receipt for your purchase, in its own name, and sends it to you automatically by e-mail with a PDF attached. If you need a purchase document for your employer or your accounts, that is the one to use — enter your company name and, where offered, your VAT number at checkout so it appears on the invoice. We do not issue a separate invoice for your order, and we cannot reissue Onelink's.

You can see your order history, update your billing details and manage your purchases at onelink.com.

5. Payment​

Payment is taken by Onelink, Stripe's merchant-of-record service. Onelink is the seller for the purposes of the sale, handles the card transaction, and applies its own Terms of Service and Privacy Policy to it.

We never receive or store your card number. A charge for a package appears on your statement as LINK.COM* followed by our descriptor, rather than under our name — if you do not recognise a charge, that is what it is.

6. Delivery​

Delivery is electronic and immediate. Once payment succeeds, the package becomes downloadable from the product page while signed in to the account that made the purchase. Download links are personal to you.

If the download does not work, contact us and we will make the file available by another route. Failure of your own equipment or internet connection is not a failure of delivery, but we will not leave you without the product.

7. Withdrawal and refunds​

Refunds and withdrawal are handled by Onelink, because Onelink is the seller. Digital content that has been downloaded cannot be returned. In short:

  • Before download — consumers have a 14-day right of withdrawal and a full refund, exercised against Onelink.
  • At download — you are shown the point at which delivery begins and asked to confirm it. Once the download has begun, the right of withdrawal is extinguished.
  • After download — a refund is at Onelink's discretion. Stripe can issue one within 60 days of the transaction, and may do so without our agreement. We can support a request but cannot grant or refuse one.
  • Your statutory rights if the product is faulty or not as described are unaffected, and you may raise those with either of us.

Contact Onelink first — through the receipt e-mailed to you, from your order at onelink.com, or at support.onelink.com. If you contact us instead we will forward it and confirm to you that we have, so you lose no time; but Onelink is the party that decides and pays.

The full position, including what we record at download, is on the Refund and Withdrawal Policy page and in Section 11 of the EULA.

8. Acceptable use of the Site​

Do not attempt to gain unauthorised access to the Site, its backend or other users' accounts; do not scrape, overload or interfere with it; do not circumvent the purchase or download controls; and do not republish, resell or redistribute our materials except as the EULA expressly allows.

9. Intellectual property​

All content on the Site and in the packages — text, diagrams, templates, decision records, code samples and branding — is owned by us or licensed to us. Buying a package grants you the licence described in the EULA and nothing more.

10. Availability​

We aim to keep the Site available but do not guarantee uninterrupted access. We may change, suspend or withdraw any part of the Site, or any product, at any time. Withdrawing a product does not affect a licence you have already bought.

11. Liability​

We provide the Site and the packages on an "as is" basis to the extent the law allows. The packages are reference architecture material, not professional advice for your specific situation, and applying them remains your decision and your responsibility. Our liability for a purchase is limited as set out in Section 9 of the EULA.

Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be excluded. If you are a consumer, your mandatory statutory rights are not affected by anything in these Terms.

12. Changes to these Terms​

We may update these Terms. The version in force when you place an order is the one that applies to that order. Material changes will be announced on the Site.

13. Governing law and disputes​

These Terms are governed by Hungarian law. If you are a consumer resident in the EU, you also keep the protection of the mandatory law of your country of residence.

If you are a consumer and we cannot resolve a complaint directly, you may turn to the conciliation board attached to your local chamber of commerce. The board competent for us is the Budapesti Békéltető Testület (1016 Budapest, Krisztina krt. 99., bekelteto.testulet@bkik.hu). Consumer complaints about market conduct may also be made to the district office (kormányhivatal) acting as consumer-protection authority.

Otherwise, disputes fall to the courts of Hungary.
