However, information may occasionally contain:

Where an error is identified, we may correct or update the relevant information.

If a material error affects an order already submitted, we may contact the customer and provide an appropriate solution in accordance with applicable law.

Nothing in this section limits mandatory consumer rights.

5. Product Information

We make reasonable efforts to present product descriptions, specifications and images accurately.

However, minor differences may occur because of:

• Screen or display settings;

• Lighting;

• Photography;

• Manufacturing variations;

• Product improvements; or

• Other technical factors.

Product images are generally provided for illustrative and informational purposes.

Actual colors, dimensions or appearance may differ slightly from those displayed on a customer's device.

This does not affect statutory rights where a product is defective, incorrectly described or otherwise does not conform to the purchase contract.

6. Prices and Availability

Prices and product availability displayed through the online store may change from time to time.

The final applicable price and other relevant charges will normally be displayed during checkout before the order is submitted.

Products remain subject to availability.

If a product becomes unavailable after an order has been placed, we may:

• Contact the customer;

• Offer an appropriate alternative;

• Cancel the affected item; or

• Issue an applicable refund.

Any cancellation or refund will be handled in accordance with our applicable policies and mandatory consumer law.

7. Intellectual Property Rights

Unless otherwise stated, content made available through our online store may be protected by intellectual property laws.

This may include:

• Business names;

• Brand names;

• Logos;

• Product names;

• Product descriptions;

• Photographs;

• Graphics;

• Videos;

• Text;

• Layouts;

• Designs;

• Software; and

• Other website content.

Such content may be owned by:

• Butterberg ApS;

• Shopify;

• Product manufacturers;

• Licensors;

• Service providers; or

• Other legitimate rights holders.

You may view and use the website for lawful personal purposes.

Unless authorized by the relevant rights holder or permitted by law, you must not:

No ownership rights are transferred to users merely by accessing the online store.

8. Trademarks

Company names, product names, logos, trademarks and other commercial identifiers displayed on the website may be protected by applicable trademark or intellectual property law.

The presence of a trademark on our website does not automatically mean that Butterberg ApS owns that trademark.

Third-party trademarks remain the property of their respective owners.

No license to use any trademark is granted unless expressly stated.

9. Third-Party Content

Certain information, images, trademarks, technical specifications or other content may originate from manufacturers, suppliers, Shopify, service providers or other third parties.

Where appropriate, ownership remains with the relevant rights holder.

We do not claim ownership of third-party intellectual property solely because it appears on our online store.

10. External Links

Our online store may contain links to websites, platforms or services operated by independent third parties.

These may include:

• Payment providers;

• Delivery providers;

• Social media platforms;

• Manufacturers;

• Business partners; or

• Other external services.

We do not necessarily control the content, security or availability of external websites.

When you visit an independent third-party website, that provider's own:

• Terms of service;

• Privacy policy;

• Cookie policy; and

• Other legal terms

may apply.

The inclusion of an external link does not automatically mean that we endorse or accept responsibility for that third party.

11. Third-Party Services

Our online store may use independent third-party services for functions such as:

• Payments;

• Shipping;

• Order fulfilment;

• Analytics;

• Customer support;

• Advertising;

• Fraud prevention; or

• Other technical services.

These providers may operate according to their own legal terms and privacy practices.

To the extent permitted by applicable law, Butterberg ApS is not responsible for failures caused exclusively by independent third-party services outside our reasonable control.

Mandatory consumer rights remain unaffected.

12. Website Availability

We make reasonable efforts to keep our online store accessible and functioning correctly.

However, uninterrupted availability cannot be guaranteed.

Temporary interruptions may occur because of:

• Technical maintenance;

• Shopify platform maintenance;

• Software updates;

• Internet outages;

• Hosting problems;

• Cybersecurity incidents;

• Third-party service interruptions; or

• Other circumstances outside our reasonable control.

We may temporarily suspend or restrict access where reasonably necessary for maintenance, security or legal reasons.

13. Liability

Nothing in this Legal Notice excludes or limits liability that cannot legally be excluded or limited.

Subject to applicable law, Butterberg ApS will not be responsible for losses caused solely by circumstances outside our reasonable control.

We do not seek to exclude liability for:

• Mandatory consumer rights;

• Fraud;

• Intentional misconduct;

• Billing address;

• Delivery address;

Customers should review order information before completing checkout.

We may not be responsible for delivery problems caused solely by inaccurate or incomplete information provided by the customer, subject to applicable law.

Consumers in the European Union and European Economic Area may have statutory rights concerning matters including:

• Product conformity;

• Defective goods;

• Distance-selling contracts;

• Cancellation or withdrawal;

• Refunds; and

• Consumer dispute resolution.

Our voluntary commercial policies provide additional rights only where expressly stated and do not replace mandatory legal protections.

Returns, exchanges and refunds are governed by our Return and Refund Policy.

Eligible EU/EEA consumers generally have a statutory 14-day right of withdrawal for qualifying distance purchases, subject to legal exceptions.

We also provide an additional 30-day voluntary return policy for eligible products under the conditions stated in our Return and Refund Policy.

Customers should review that Policy before requesting or sending a return.

20. Governing Law

Unless mandatory consumer law requires otherwise, the operation of our online store and agreements entered into with Butterberg ApS are generally governed by the laws of Denmark.

For consumers located in another country, this choice of law does not remove mandatory consumer protections that apply under the laws of the customer's country of residence.

If you have a complaint or dispute, we encourage you to contact us first so that we can attempt to resolve the matter directly.

Please contact:
