NCTV.nl uses the statistics program Piwik to analyse which pages are visited most, how visitors arrive at our website and which search terms they enter into our search engine.

Just as every other website, we collect the IP addresses of our visitors for this purpose. These addresses are stored in so-called log files. The log files are stored on the web server for five days to make them available for Piwik. After this period, the log files are stored during 90 days for security reasons only and are also viewed for this purpose only.

The Dutch Data Protection Authority has taken measures aimed at limiting the traceability of visitors to our website as much as possible. We do so by immediately discarding the last two octets (number sequences) of each IP address after importing the log files into Piwik. They are put into a temporary memory before the IP addresses are saved in Piwik.

We collect the following data through the log files:

  • cookies;
  • IP addresses;
  • user agents (browsers, operating systems);
  • search terms used in order to arrive at our website from external search engines;
  • search terms used in the search engine on the website itself;
  • links used on the website;
  • links used to arrive at the website.

Piwik retrieves these data from the web server’s log files. These log files remain in Piwik’s database for 31 days, after which period they are deleted. All that remains then is an aggregated (merged) log file. This file provides us with an annual report on website visits.

We do not pass on any personal data to third parties, unless doing so is legally required or in order to report criminal offences.
