Terms of Service

Last Updated: September 30, 2026

Overview

This website is operated by Marstek Energy GmbH. Throughout the Website, the terms “we,” “us,” and “our” refer to Marstek Energy GmbH.

Marstek Energy GmbH provides this Website, including all information, tools, and services available through the Website, subject to your acceptance of all terms, conditions, policies, and notices stated herein.

By accessing our Website and/or purchasing our products, you engage in our “Services” and agree to be bound by these Terms of Service (“Terms”), including any additional terms and conditions and policies referenced herein and/or made available by hyperlink.

These Terms apply to all users of the Website, including, without limitation, browsers, suppliers, customers, merchants, and/or content contributors.

Please read these Terms carefully before accessing or using our Website. By accessing or using any part of the Website, you agree to be bound by these Terms.

If you do not agree to all of these Terms, you may not access the Website or use the Services. Where these Terms are deemed to constitute an offer, acceptance is expressly limited to these Terms.

Any new features or tools added to the current Website shall also be subject to these Terms.

You may review the most current version of these Terms at any time on this page. We reserve the right to update, modify, or replace any part of these Terms by posting updates and/or changes on the Website.

You are responsible for periodically checking this page for changes. Your continued use of or access to the Website after changes are posted constitutes acceptance of those changes.

Section 1 — Eligibility and Other Provisions

You represent that, if you are a consumer, you have reached the age of majority required in your jurisdiction to enter into a legally binding agreement. If you place an order on behalf of a business, you represent that you are duly authorized to do so.

You may not use the Website for any unlawful purpose or upload, transmit, or distribute viruses or other destructive code.

If you violate these Terms, we may terminate your account and refuse future orders to the extent permitted by applicable law.

You may not use our products for any unlawful or unauthorized purpose or violate any applicable laws or regulations while using the Services, including but not limited to copyright laws.

Any violation of these Terms may result in termination of the relevant Services, subject to applicable law.

These Terms do not exclude or restrict the validity of individual agreements separately entered into between you and us. Pursuant to Section 305b of the German Civil Code (BGB), individually negotiated agreements take precedence over these Terms.

Section 2 — Accuracy, Completeness and Timeliness of Information

We use reasonable commercial efforts to ensure that information presented on the Website is accurate and clear.

The Website may also contain historical information. Such information does not form part of a sales contract and is provided for general reference only. We do not guarantee that historical information is complete or current or that archived information corresponds to the latest status of products currently offered for sale.

We reserve the right to modify, correct, or remove Website content at any time due to business requirements, product updates, price adjustments, or typographical errors.

Any subsequent modification to Website content shall not affect a sales contract that has already been concluded through an order confirmation.

Section 3 — Products, Prices and Services

Information relating to products and services, including prices, descriptions, availability, and delivery options, is displayed on the relevant product pages of the Marstek Website.

We make reasonable efforts to display product colors and images as accurately as possible. However, we cannot guarantee that the display of colors on your computer or other device will accurately reflect the actual product colors.

Before an order is confirmed, we reserve the right to modify product descriptions and prices at any time.

After an order has been confirmed, the price and product description contained in the confirmed order are binding on both parties and may not be unilaterally changed.

We reserve the right to discontinue products at any time. Offers for products or services on the Website are void where prohibited by law.

To the extent permitted by applicable law, if information concerning a product or service on the Website is inaccurate, such as a typographical pricing error, and the error was not discovered before order confirmation, we reserve the right to correct or modify the information or cancel the order, or part of the order, before shipment.

In such circumstances, we may contact you for further instructions or notify you of the cancellation and provide a refund.

Section 4 — Shipping and Delivery

Order processing times, estimated delivery times, carriers, and special delivery requirements for large or heavy products are described in our Shipping Policy.

If a product is out of stock or we are unable to fulfill an order, we will notify you as soon as reasonably possible.

You may choose to wait for the product to become available, select an alternative product, or cancel the affected order and receive a full refund.

Section 5 — Order Cancellation, Returns and Refunds

If you are not completely satisfied with a product you purchased and the applicable requirements for a refund are met, you may contact us during the applicable 30-day refund period to arrange a refund.

For detailed information regarding order cancellation, returns, and refunds, please refer to our Order Cancellation, Return & Refund Policy.

Section 6 — Statutory Right of Withdrawal

If you are a consumer, you generally have a statutory right of withdrawal of 14 days without giving any reason, subject to the statutory requirements and exceptions.

The withdrawal period generally begins when you or a third party designated by you, other than the carrier, takes physical possession of the goods.

You may exercise your right of withdrawal by using the official withdrawal form, by email, or by written notice. Where required by applicable law, the Website also provides an online withdrawal function.

Statutory exceptions to the right of withdrawal apply where expressly provided by law, for example for certain customized products.

Further information regarding refunds, return shipping costs, and return requirements is provided in our Order Cancellation, Return & Refund Policy.

For more information, please refer to our Withdrawal Policy.

Section 7 — Payments, Billing and Account Information

Products displayed on the Website constitute an invitation to submit an offer and do not, by themselves, constitute a binding offer to conclude a sales contract.

By submitting an order, you make an offer to enter into a sales contract with us.

We may reject an order for objective and reasonable reasons permitted by applicable law.

Reasonable reasons may include product unavailability, obvious pricing or product-information errors, suspected fraud, abusive or malicious ordering activity, a risk of stockpiling or unauthorized resale, or a violation of these Terms.

To prevent stockpiling and protect product availability, we may impose reasonable purchase quantity limits per customer for individual orders or specified periods.

Any such quantity limits will be disclosed in advance on the relevant product page or checkout page.

When identifying multiple-account stockpiling or abusive repeated ordering, we may consider information such as the same customer account, payment card, billing address, shipping address, or other relevant order information.

If we modify or cancel an order, we may attempt to notify you using the email address and/or billing address or telephone number provided when the order was placed.

You agree to provide current, complete, and accurate purchase and account information for all purchases made through our store.

You agree to promptly update your account and other information, including your email address, payment card details, and expiration date, so that we can complete your transactions and contact you when necessary.

Available payment methods are displayed at checkout. You are responsible for ensuring that your selected payment method is valid.

For additional information, please refer to our Refund Policy.

Section 8 — Warranty

Your statutory consumer rights relating to statutory liability for defects are not restricted by these Terms.

Our voluntary commercial warranty is described in our Warranty Policy.

Our commercial warranty does not replace or limit your statutory rights relating to defects.

Section 9 — Optional Tools

We may provide you with access to third-party tools over which we neither monitor nor exercise control or involvement.

To the extent permitted by applicable law, such tools are provided on an “as available” basis.

To the extent permitted by applicable law, our liability for damage arising from your use of third-party tools is excluded or limited.

This provision does not apply to liability that cannot legally be excluded or limited under Section 16.

Your use of optional tools is at your own risk.

You should ensure that you are familiar with and accept the terms applicable to such tools provided by the relevant third-party provider.

Section 10 — Third-Party Links

Certain content, components, or technologies displayed through the Services may be provided by third parties.

The Website may also contain links to external third-party websites.

External third-party websites are not controlled by us, and their content and policies are the responsibility of the respective third parties.

If you click an external link and complete a transaction entirely on an independent third-party website, we are not responsible for the accuracy or completeness of the content, products, services, or transaction processes of that third-party website, except to the extent required by applicable law.

Before entering into a transaction with a third party, you should review that third party's terms of service, privacy policy, and return and refund rules.

Complaints and claims relating to transactions with such third parties should generally be directed to the relevant third party.

Section 11 — User Comments, Feedback and Other Submissions

If you submit comments, reviews, feedback, ideas, or other suggestions to us, you grant us a free, non-exclusive right to use, edit, reproduce, and distribute such content to the extent permitted by law, without prejudice to your statutory personal rights.

We reserve the right to remove user comments that are unlawful, abusive, defamatory, infringing, or contain viruses or other malicious code.

You represent that content you publish does not infringe the copyrights, portrait rights, privacy rights, or other rights of third parties.

To the extent permitted by applicable law, you shall be responsible for third-party claims arising from content you publish.

Section 12 — Personal Information

We process information you provide in accordance with our Privacy Policy, including for purposes of verifying your identity where necessary.

You represent that all user information relating to your account and your use of Marstek Services is current, complete, and accurate.

You represent that you will not knowingly submit false information, including usernames, photographs, or profile information, for the purpose of impersonating another person, whether real or fictional.

If we reasonably determine that information you provide is not current, complete, or accurate, we reserve the right, to the extent permitted by law, to refuse or terminate the provision of Services.

Personal information submitted through the Website is subject to our Privacy Policy.

Section 13 — Errors, Inaccuracies and Omissions

From time to time, information on our Website or in our Services may contain typographical errors, inaccuracies, or omissions relating to product descriptions, prices, promotions, offers, shipping charges, delivery times, or availability.

We reserve the right to correct errors, inaccuracies, or omissions and to change or update information or cancel an order where information is inaccurate, to the extent permitted by applicable law.

We are not obligated to update, modify, or clarify information contained in the Services or related websites, including pricing information, unless required by law.

The absence of a specified update or refresh date does not mean that all information on the Services or related websites has been updated or modified.

Section 14 — Privacy and Cookies

The Website uses Cookies to collect certain information about you.

Please carefully read our Privacy Policy and Cookie Policy for further information.

Section 15 — Prohibited Uses

In addition to other prohibitions set forth in these Terms, you are prohibited from using the Website or its content:

(a) for any unlawful purpose;

(b) to solicit others to perform or participate in unlawful acts;

(c) to violate any applicable international, federal, state, provincial, or local laws, rules, or regulations;

(d) to infringe or violate our intellectual property rights or the intellectual property rights of others;

(e) to harass, abuse, insult, harm, defame, slander, intimidate, or discriminate against others on the basis of sex, sexual orientation, religion, ethnicity, race, age, nationality, or disability;

(f) to submit false or misleading information;

(g) to upload or transmit viruses or other malicious code that may affect the functionality or operation of the Services, related websites, other websites, or the Internet;

(h) to collect or track the personal information of others;

(i) to engage in spam, phishing, or similar activities;

(j) for any obscene or immoral purpose; or

(k) to interfere with or circumvent the security features of the Services, related websites, other websites, or the Internet.

We reserve the right to terminate your use of the Services or related websites if you violate any prohibited use, subject to applicable law.

Section 16 — Disclaimer and Limitation of Liability

We do not guarantee, represent, or warrant that your use of our Services will be uninterrupted, timely, secure, or error-free.

We may temporarily suspend or discontinue individual Services where permitted by law. Any statutory rights you may have remain unaffected.

You expressly agree that your use of, or inability to use, the Services is at your own risk.

Except where we expressly provide otherwise, the Services and all products and services delivered to you through the Services are provided on an “as is” and “as available” basis, subject to the mandatory rights and protections provided by applicable law.

Nothing in these Terms excludes or limits statutory liability for defects, mandatory consumer rights, or any other liability that cannot legally be excluded or limited.

We are liable for damages caused by slight negligence in the breach of essential contractual obligations only to the extent such damages were typically foreseeable at the time the contract was concluded.

Essential contractual obligations are obligations whose performance is necessary for the proper execution of the contract and on whose compliance the contractual partner may ordinarily rely.

The limitations of liability above do not apply to damages resulting from injury to life, body, or health, damages caused intentionally or by gross negligence, or liability under the German Product Liability Act (Produkthaftungsgesetz).

The above limitations of liability also apply to the personal liability of our legal representatives and vicarious agents.

Nothing in these Terms limits or excludes your statutory rights relating to defects under Sections 434 et seq. of the German Civil Code (BGB).

Section 17 — Indemnification

To the extent permitted by applicable law, if you violate these Terms and thereby cause a third-party claim against Marstek Energy GmbH, its parent companies, subsidiaries, affiliates, partners, officers, directors, agents, contractors, licensors, service providers, subcontractors, suppliers, or interns, you shall be responsible for defending and indemnifying the affected party against such third-party claims, losses, liabilities, damages, judgments, awards, fines, costs, and expenses, including reasonable attorneys' fees and court costs, to the extent attributable to your breach.

Section 18 — Severability

If any provision of these Terms is determined to be unlawful, invalid, or unenforceable, that provision shall remain enforceable to the maximum extent permitted by applicable law.

Any unenforceable portion shall be deemed severed from these Terms to the extent necessary.

Such determination shall not affect the validity and enforceability of the remaining provisions.

Section 19 — Termination

The rights and obligations of the parties that arose before termination shall survive termination to the extent required by their nature or applicable law.

These Terms remain effective unless terminated by you or us.

You may terminate your use of the Services at any time by notifying us that you no longer wish to use the Services or by ceasing to use the Website.

If you materially breach these Terms and fail to remedy the breach within fourteen days after receiving written notice, we may terminate these Terms to the extent permitted by applicable law.

In urgent circumstances, such as fraud, distribution of malicious code, or serious threats to Website security, we may take immediate action without prior notice to the extent permitted by law.

Termination does not affect rights and obligations that arose before the termination date, including payment obligations incurred before termination.

Section 20 — Entire Agreement

Our failure to exercise or enforce any right or provision of these Terms shall not constitute a waiver of such right or provision.

These Terms, together with any policies or operating rules posted by us on the Website or in connection with the Services, constitute the agreement between you and us governing your use of the Services, subject to any individually negotiated agreements.

Mandatory statutory rights and individually negotiated agreements remain unaffected.

Any ambiguity in the interpretation of these Terms shall not automatically be interpreted against the drafting party.

Section 21 — Governing Law and Dispute Resolution

These Terms and any separate agreement under which we provide Services to you are governed by the laws of the Federal Republic of Germany.

For consumers residing in another EU or EEA Member State, this choice of law does not deprive you of the protection afforded by mandatory provisions of the law of the country in which you habitually reside.

Such mandatory consumer protection provisions shall prevail where applicable.

This section determines the applicable substantive law only and does not determine the competent court.

Consumers may have the right to bring proceedings before the courts of their place of habitual residence in accordance with applicable law.

EU Online Dispute Resolution (ODR): The EU Online Dispute Resolution platform was discontinued on July 20, 2025. No ODR platform link is therefore provided here.

We do not participate in voluntary consumer dispute resolution proceedings unless expressly stated otherwise.

Section 22 — Changes to These Terms of Service

You may review the most current version of these Terms at any time on this page.

We reserve the right to update, modify, or replace any part of these Terms by posting updates and changes on the Website.

You are responsible for regularly reviewing the Website for updates.

Your continued use of or access to the Website or Services after changes have been posted constitutes acceptance of the changes, to the extent permitted by applicable law.
