Due to EU privacy laws EU web sites are required by law to disclose the type of cookies that are created from their site.
What follows is a description of Olark cookies which we believe to be in compliance with the "only necessary" aspect of setting cookies outlined in the EU rules for Internet privacy.
a visitor identifier that we use only on your site to remember this visitor between visits
a session identifier that we use only on your site to keep track of a single chat session
storage identifier that we use to maintain chat state across pages (e.g. message history)
extra state information (e.g. chat box being open/closed)
most recent Olark site ID (security measure)
the Olark loader version (for improved caching)
used for caching purposes (loaded from CDN vs. loaded from our infrastructure)
group id the visitor is locked to
used for caching by setting a hash for assets to determine if they have changed and if they need to be refreshed
used to test whether the visitor's browser allows cookies to be stored
