2. Binding nature

By registering on, accessing or otherwise using this website, you hereby agree to be bound by these Terms and Conditions set out below. The mere use of this website implies your knowledge and acceptance of these Terms and Conditions. In certain cases, we may also ask you to give your explicit consent.

4. Intellectual property

We or our licensors own and control all copyright and other intellectual property rights in the website as well as the data, information and other resources displayed on or accessible through it.

4.1 All rights reserved

Unless specific content states otherwise, you are not granted any licence or other right under copyright, trademark, patent or other intellectual property laws. This means you may not use, copy, reproduce, perform, display, distribute, embed into an electronic medium, modify, reverse-engineer, decompile, transfer, download, transmit, monetise, sell, market or commercialise any resources on this website in any form without our prior written permission, except as otherwise provided by mandatory legal provisions (such as the right to quotation).

5. Third-party ownership

Our website may contain hyperlinks or other references to third-party websites. We do not monitor or review the content of third-party websites referred to by this website. Products or services offered by other websites are subject to the Terms and Conditions of those third parties. Opinions or material expressed on such websites are not necessarily shared or endorsed by us.

We are not responsible for the privacy practices or the content of these websites. You bear all risks associated with the use of such websites and any related third-party services. We accept no responsibility for any loss or damage of any kind arising from your disclosure of personal data to third parties.

You may not use our website or services to publish or distribute material that consists of (or is linked to) malicious computer software. You must not use data collected from our website for direct marketing activities or conduct systematic or automated data collection activities on or in relation to our website.

Engaging in any activity that causes or may cause damage to the website or that impairs the performance, availability or accessibility of the website is strictly prohibited.

7. Refund and return policy

7.1 Right of withdrawal

You have the right to withdraw from this contract within 14 days without giving any reason.

The withdrawal period expires 14 days after the date of conclusion of the contract.

To exercise the right of withdrawal, you must inform us of your decision to withdraw from this contract by means of a clear statement (e.g. a letter sent by post, fax or email). Our contact details can be found below. You may use the attached model withdrawal form, but this is not obligatory.

You may also complete and submit the model withdrawal form or another clear statement electronically on our website.

If you use this option, we will send you without delay an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by email).

To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.

7.2 Effects of withdrawal

If you withdraw from this contract, we shall reimburse you all payments received from you, including delivery costs (except for the additional costs resulting from your choice of a type of delivery other than the least expensive standard delivery offered by us), without undue delay and in any event not later than 14 days from the day on which we are informed of your decision to withdraw from this contract. We will carry out such reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.

If you requested that performance of services begin during the withdrawal period, you shall pay us an amount proportionate to what has been provided until you have communicated to us your withdrawal from this contract, compared with the full coverage of the contract.

Please note that there are certain legal exceptions to the right of withdrawal, and some items therefore cannot be returned or exchanged. We will inform you if this applies to your specific case.

8. Submission of ideas

Do not submit ideas, inventions, works of authorship or other information that may be considered your own intellectual property and that you wish to present to us unless we have first signed an agreement regarding intellectual property or a non-disclosure agreement. If you disclose such information to us without such a written agreement, you grant us a worldwide, irrevocable, non-exclusive, royalty-free licence to use, reproduce, store, adapt, publish, translate and distribute your content in any existing or future media.

9. Termination of use

We may, at our sole discretion, modify or discontinue access to the website or any service on it temporarily or permanently at any time. You agree that we shall not be liable to you or any third party for any such modification, suspension or discontinuation of your access to or use of the website or any content you may have shared. You shall not be entitled to any compensation or other payment, even if certain features, settings and/or content you have provided or rely upon are permanently lost. You may not circumvent or attempt to circumvent any access restriction measures on our website.

15. Force majeure

Except for payment obligations, any delay, failure or omission by either party to perform or comply with any of its obligations under these Terms and Conditions shall not be considered a breach if and so long as such delay, failure or omission is caused by an event beyond the reasonable control of that party.

16. Indemnification
