Legal information
Terms of sale
For digital purchases you make directly from Keelwake (for example unlocking an SKS or FKN trainer through Stripe). Purchases made through the Apple App Store are handled by Apple under its own terms.
Please note: this English page is a courtesy translation. The binding version is the German Allgemeine Geschäftsbedingungen (AGB).
1. Provider and scope
The provider and contractual partner for direct purchases is Miaris Engineering Systems, owner Niko Miaris, Helene-und-Maria-Schieß-Straße 8, 78467 Konstanz, Germany (hereinafter “we”). These terms of sale (Allgemeine Geschäftsbedingungen, AGB) apply to contracts for digital content that consumers with a billing address in Germany conclude with us directly through the Keelwake web app at keelwake.de.
2. Subject matter of the contract
The subject matter is the account-bound, unlimited unlock of the digital course designated at the time of purchase in Keelwake (currently SKS or FKN). The course comprises the question catalogue described, the Keelwake learning system, exam simulation and learning statistics. The unlock applies in the web app as well as in the respectively supported Keelwake apps on iPhone, iPad and Mac if you are signed in there with the same Keelwake account. A Keelwake account, a current browser version or a supported Apple app, and an internet connection for signing in and syncing are required. This is a one-off payment without a subscription.
3. Conclusion of the contract
The presentation of the respective product in the purchase summary constitutes a binding offer on our part. Before you are forwarded to the payment provider, the product, the total price, the features, the technical requirements and the necessary declarations are summarised once more. You can correct input errors up until the payment provider is called up. By completing the payment process, which is expressly marked as subject to payment, at the payment provider, you accept the offer; the contract is concluded upon successful payment.
Immediately afterwards we send the contract confirmation, the terms of sale applicable at the time of purchase and the cancellation policy (Widerrufsbelehrung) to the email address linked to your account. We store the text of the contract; you additionally receive the essential order data and contract documents on a durable medium by email.
4. Prices and payment
The total price stated in euros before the purchase applies. No further costs are charged by Keelwake. In accordance with § 19 UStG (small business regulation, Kleinunternehmerregelung) no value added tax is shown. Payment is made through the payment provider offered in the purchase summary, currently Stripe (Stripe Payments Europe, Ltd., Ireland). Details on data processing can be found in our privacy policy.
5. Provision
At your express request, the digital content is provided immediately after successful payment by unlocking the course on your account. It is not provided on a tangible medium. We provide functional and security-related updates to the extent required by law. There is no entitlement to permanent support for outdated operating system or browser versions.
6. Right of cancellation
Consumers have a statutory right of cancellation (Widerrufsrecht). The details are governed by our cancellation policy (Widerrufsbelehrung). In the case of digital content not supplied on a tangible medium, the right of cancellation expires when performance of the contract begins, provided the statutory conditions are met: you have expressly agreed to performance beginning before the cancellation period expires, confirmed your knowledge that you thereby lose your right of cancellation, and received a contract confirmation (§ 356 (5) BGB). We obtain these declarations expressly before payment, in a separate consent statement that is not pre-selected.
A direct purchase can also be cancelled at any time through our permanently available online function “Cancel contract” (Vertrag widerrufen).
7. Warranty
The statutory provisions on contracts for the supply of digital products (§§ 327 ff. BGB) apply. If the digital content is defective, you have the statutory rights to subsequent performance, a price reduction or termination of the contract.
8. Liability
We are liable without limitation for intent and gross negligence, and for injury to life, body or health. In the case of ordinary negligence we are liable only for the breach of a material contractual obligation (Kardinalpflicht) and limited to the foreseeable damage typical of this type of contract. The nautical chart shown in the app serves for planning and orientation and does not replace official nautical charts and nautical publications; you use it at your own responsibility.
9. Consumer dispute resolution
We are neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration board (§ 36 VSBG).
10. Final provisions
The law of the Federal Republic of Germany applies, to the exclusion of the UN Convention on Contracts for the International Sale of Goods. Mandatory consumer protection provisions of the state of your habitual residence remain unaffected. Should individual provisions be invalid, the validity of the remaining provisions remains unaffected.
