We will endeavour to notify you of significant content removal actions where legally permissible.

6.1 BioPrintHub Content

All content, design, software, graphics, text, and other materials created or owned by Black Drop Biomedical and made available through the Platform are the exclusive property of Black Drop Biomedical or its licensors and are protected by applicable Intellectual Property Rights.

If you believe that Content on the Platform infringes your Intellectual Property Rights, please contact us at blackdropbiomedical@gmail.com with a description of the allegedly infringing Content, your contact information, and a statement that you have a good-faith belief that the use is unauthorised. We will investigate and respond in accordance with applicable law.

The Platform may integrate with or link to third-party websites, databases, repositories, or services (such as ORCID, Zenodo, or institutional repositories). These third-party services are governed by their own terms and privacy policies. We are not responsible for the availability, accuracy, or content of third-party services, and a link or integration does not imply our endorsement.

Any transactions or interactions you conduct with third parties through the Platform are solely between you and that third party. We shall have no liability for any loss or damage arising from your use of third-party services.

8.1. You may close your account at any time through your account settings or by contacting us at support@bioprinthub.com. Upon closure, your account data will be handled in accordance with our Privacy Policy.

Upon termination, your licence to use the Platform ceases immediately. Sections of these Terms that by their nature should survive termination (including Sections 5, 6, 10, 11, and 14) will continue to apply.

8.3. Upon account termination, publicly shared Content may remain on the Platform unless you request its removal prior to termination. We will endeavour to accommodate reasonable removal requests but are not obligated to remove Content that has already been accessed or cited by other users.

We may update these Terms from time to time. We will notify you of material changes by posting the updated Terms on the Platform and, where required, by email or Platform notification. Your continued use of the Platform after the effective date of the revised Terms constitutes your acceptance. If you do not agree with the revised Terms, you must stop using the Platform.

In the event of a dispute arising out of or in connection with these Terms or your use of the Platform, we encourage you to first contact us at legal@bioprinthub.com to seek an informal resolution.

If the dispute cannot be resolved informally, it shall be submitted to the exclusive jurisdiction of the Portuguese courts, specifically the courts of the district where Black Drop Biomedical is registered, unless mandatory consumer protection law requires otherwise.

Consumers in Portugal have the right to use alternative dispute resolution (ADR) entities. A list of accredited entities is available at the Portuguese Consumer Portal: https://www.consumidor.gov.pt.
