Contact
One real mailbox today, security reports, and the honest state of everything else.
Send vulnerability reports to security@metricward.eu. This address is monitored by a human with a 72-hour first-response commitment. Full policy, scope and machine-readable contact are on /security.
There is no general support address yet, and rather than print one that silently drops your message, this page says so. Security reports have a real, monitored mailbox above. For everything else the two resources below answer most questions already.
