Hit Counter Cookies
Dalgan uses a hit counter called Matomo which may put cookies on your system for the purposes of recording repeat visits to the site. This is important because, for example, to accurately measure the number of visitors we get,
two different people visiting should be recorded as separate from the same person visiting twice. This information is anonymised and stored locally, it does not leave the European Union at any point and is transferred to no third parties for processing.
