wecantrack’s WordPress plugin places two additional first party cookies (called ‘_wct_http_referrer_1‘ and ‘_wct_http_referrer_2′) which are used to retrieve the correct clickout_url and redirect_url.
By standard, wecantrack does not track any personal data, but anonymised IP addresses. Anonymised IP addresses can not be traced back to any real persons and are simply used to determine the geographical region of the visitor.
Publishers can only track personal data via wecantrack by making use of the metadata, custom index or subid capabilities. It is the publisher’s responsibility to comply with data privacy regulations. wecantrack, as data processor, is in no position to give advice in this matter.
The publisher, as data controller, carries full responsibility and thus needs to define its actions towards data regulation compliancy on its own or by seeking legal advice from someone who is in the position to deliver it.
