To understand which pages are viewed and their frequency, this site uses Matomo Analytics. This system places cookies to track which pages you view. The name of this cookie starts with "_pk_". We do not literally find out 'who' you are. We only see a portion of your IP address and some properties of your browser. This data is not linked to your name, address, or email address. The cookie file starting with "_pk_id" remains on your computer for one year (unless you delete it) so that Matomo can identify if you are a returning visitor.
Additionally, a necessary session cookie is placed. The name of this cookie starts with "evo". This cookie is essential because it keeps track of which samples you wish to order. This cookie is deleted after your browser is closed.
We are not required to ask for permission for the site to place these cookies, as they fall within the guidelines of the ACM's cookie provisions.
