  • We use a fair-support policy. We do not impose a hard limit on the amount of support that we provide. But there are (soft) limits to the amount of support that we can reasonably provide for the prices as listed above. Therefore, if these limits are reached, we reserve the right to limit the amount of support that we provide. We will always do so in good communication with you, and we will offer alternatives. But the decision about if and when these limits are reached is up to us. We aim to respond to questions within a reasonable time frame, but we do not offer 24/7 support.
  • We use Mattermost for communication. If you purchase individual support, you will receive one account. If you purchase organizational support, we will create a team for your organization at chat.cogsci.nl/[organization name].
  • Prices as listed above do not include value-added tax (VAT). If you or your organization has a European VAT number that is not registered in the Netherlands, then you will receive an invoice with the prices as listed above, and VAT will be "reverse-charged". In all other cases, you or your organization will receive an invoice that includes 21% VAT in addition to the prices as listed above. This is stipulated by European tax law.
