1. Acceptance of Terms
Welcome to QuantumHarbor. These Terms of Service ("Terms") govern your use of the QuantumHarbor marketplace platform and related services provided by QuantumHarbor B.V., a Dutch company registered in the Netherlands.

As a marketplace operator, QuantumHarbor acts as an intermediary between buyers and sellers. We provide the technological infrastructure, payment processing services, and support systems, but the actual sale contracts are formed directly between buyers and sellers.
We reserve the right to modify, suspend, or discontinue any aspect of our services at any time, with or without notice, though we will endeavour to provide reasonable advance notice of significant changes.

Intellectual Property Infringement
We respect intellectual property rights and expect our users to do the same. If you believe your intellectual property rights have been infringed, please contact us immediately with detailed information about the alleged infringement.

Platform Availability
While we strive to maintain continuous service, we do not guarantee that our platform will be available at all times. We may experience downtime for maintenance, updates, or due to factors beyond our control.
Third-Party Services
Our platform may integrate with third-party services. We are not responsible for the availability, accuracy, or content of these third-party services.
