Social Media (Twitter)

On some parts of our website we have embedded our Twitter Timeline. We have enabled the 'do-not-track'/advanced privacy options for the Twitter feed and thus it should not track or store any information about you. Because Twitter still does store (quite a few) cookies when using the do-not-track features, we do require you to give your consent to enable the Twitter Feed and thus to let Twitter place cookies by enabling our Twitter timeline. We suspect that the cookies set by the Twitter Timeline are indeed anonymized, but obviously there is no 100% guarantee that this is actually correct because we don't have control over those cookies. Some of the cookies which are set by the Twitter timeline have been listed bellow, but as with many 'externally embedded content': It is impossible for us to list them all due to the fact that external content providers (unfortunately) can just 'randomly change' the way their software works.

Cookie	Duration	Description
_twitter_sess	session	This cookie allows the use of Twitter features without having to log in, and contains some tracking information that Twitter uses to improve their services. (However IF Twitter indeed does what it says, the tracking part should be disabled due to the DNT (do not track) setting).
# IMPORTANT PLEASE READ!	various	This is additional information, not a cookie! The cookies listed here are just a few of the cookies which will be set by the Twitter Timeline, there are (quite a lot of) other cookies which are also set by the Embedded Twitter Timeline when it's enabled. We do have enabled the enhanced privacy options ("do not track") features of Twitter for this Timeline, we however (of course) do not have control over possible cookies set and/or created by externally embedded content. This is also the reason why we disable the content altogether when you don't allow their cookies. You can view which cookies exactly are being placed by websites using the developer console of your browser, where and how to find this depends on your browser, but for most browsers this can be opened using F12 on your keyboard. Please make sure that you understand that externally embedded content (like the Twitter Timeline) does place additional cookies which we are not able to all list here!

(Externally provided) Advertisements

We do our best efforts to tell our ad-provider (Google AdSense) to only use non-personalized ads, and that it is not allowed to store user identifiable or tracking cookies. We explain in detail on our Privacy Policy page how we do this. But since we "trust" those big companies as much as the next person, and the fact that they do still place 'other cookies' which are necessary to deliver these non personalized advertisements, we do still require you to consent to these cookies before we will actually allow our website to show advertisements by AdSense. Bellow we've listed the cookie which is placed from within our own domain by our advertisement provider, but please keep in mind that external advertisement providers often place a 'crapload of cookies', even when using 'non-tracking-settings'. Unfortunately we are not able to list them all here because they can just 'randomly change' due to the fact that these cookies are externally controlled. NOTE: This does not include our own Direct Sponsor Advertisements, these are already 100% privacy safe, and do not use ANY tracking, statistics or cookies.

Cookie	Duration	Description
_gads	13 months	This cookie is associated with the DoubleClick for Publishers service from Google. Its purpose is to do with the showing of adverts on the site, for which the owner may earn some revenue.
# IMPORTANT PLEASE READ!	various	This is additional information, not a cookie! The cookies listed here are just a few of the cookies which will be set by our advertisement provider, there are (quite a lot of) other cookies which are also set by the advertisement provider (Google/AdSense/Doubleclick) when it's enabled. We do have enabled the enhanced privacy options ("do not track") features for these advertisements, meaning they should only show completely unrelated and non personalized advertisements. We however (of course) do not have control over possible cookies set and/or created by externally embedded content. This is also the reason why we disable the content altogether when you don't allow their cookies. You can view which cookies exactly are being placed by websites using the developer console of your browser, where and how to find this depends on your browser, but for most browsers this can be opened using F12 on your keyboard. Please make sure that you understand that externally embedded content (like the advertisements) does place additional cookies which we are not able to all list here!

Embedded Video Content (YouTube etc)

We use 'special tags/settings' like 'Enable privacy-enhanced mode' which should prevent external embedded media like YouTube videos from placing cookies on your system, however since we (of course) don't have full control over what external embedded content does, and that we did encounter such players placing (seemingly! non tracking) cookies anyway, we do require you to allow (potential) cookies set by Embedded video players on our website(s) before we can allow them to be rendered on the webpage. Websites like YouTube also state that they will not place cookies until you play the video, even if we use the -nocookie function of YouTube. We however had different results during various tests, and despite that these cookies SEEM to be non tracking, we do require your permission to allow such content to be rendered. The cookie we always see being placed by YouTube (despite using the NOCOOKIE option) is:

Cookie	Duration	Description
# IMPORTANT PLEASE READ!	various	This is additional information, not a cookie! The cookie listed here are just a few of the cookies which can be set by the embedded video player(s), During multiple tests did not encounter any other cookies being placed by the embedded player accept about 4 ("randomly named") cookies once or twice during some extensive testing while using Chrome (other browsers did not seemed to do this). We however (of course) do not have control over possible cookies set and/or created by externally embedded content. This is also the reason why we disable the content altogether when you don't allow their cookies. You can view which cookies exactly are being placed by websites using the developer console of your browser, where and how to find this depends on your browser, but for most browsers this can be opened using F12 on your keyboard. Please make sure that you understand that externally embedded content (like the Embedded Video Content) can or does place additional cookies which we are not able to all list here!
CONSENT	11 months	This cookie is placed by the youtube-nocookie.com domain, we suspect that it is used to tell the player that 'consent for cookies or user-tracking' is pending (and thus should not happen) because the data within this cookie says: "PENDING+162". However we unfortunately can't confirm this because there is almost no other website or information available about this cookie. And despite the fact that almost ANY website with "GDPR Compliance Tips" tells you to "just use the YouTube-nocookie feature" to be GDRP Compliant without having to ask user consent, we do not agree! Due to the simple fact that it does still place this cookie. And due to the fact that when enabling the "YouTube Privacy Enhanced feature" it gives a popup saying: "When you turn on privacy-enhanced mode, YouTube won't store information about visitors unless they play the video.", we just don't like this kind of 'sketchy behavior' and thus require you to allow such cookies and content before we will actually display it.
