Cookies on

On this page you will find more information about what cookies are, which cookies are used by iAgenda and how you can influence cookies.

What are cookies?

A cookie is a piece of text that is given by a web server to a visiting browser, in the hope and expectation that the browser will return it during a follow-up visit.

The cookie is a addition to the HTTP specification . The HyperText Transfer Protocol is used by everyone who visits a website: it controls the communication between a web server and a browser. However, it is not designed to view consecutive page visits as a whole. As a result, it is not automatically possible to retrieve data or settings during a follow-up visit.

To make this possible, the cookie and set cookie headers for HTTP were introduced in 1997. This specification was last updated in April 2011 and is currently referred to as RFC 6265 HTTP State Management Mechanism .

How do cookies work?

Contrary to what politicians sometimes claim, cookies themselves are no programs and also no files, and technically nothing becomes stored by the web server on the visitor's computer. The browser can decide entirely on its own. Ultimately, cookies are often saved as a file, but a web server cannot force a browser to actually store cookies or return them at a later visit.

A cookie is always tied to a specific domain or subdomain. Cookies are therefore only sent back to the same domain as where they came from. That way you know for sure that only the servers of iAgenda receive the cookies that were previously obtained via iAgenda. Also via javascript only can be accessed on iAgenda to the cookies placed by iAgenda.

An important point of cookies is that they can be received with any http request and that all known, relevant cookies are sent with each request. This also applies to the requests for requesting images, javascript and css files for a web page. Naturally the domain check is then also applied.

First-party cookies

Cookies that you get for the same domain that you visit are called first-party cookies. When viewing this page, iAgenda's cookies are therefore first-party cookies.

Third-party cookies

It is also possible that a website contains elements from third parties. Well-known examples are embedded videos, advertisements and social media buttons. If cookies are sent with these elements from their own servers, they are called third-party cookies. It is therefore possible that you come to visit iAgenda receives third-party cookies for, and other third-party websites.

If such cookies are not used, you will still see advertisements. After all, advertisements are also shown that do not use cookies.

We use these advertising cookies:

Google Analytics Google Analytics is a web analysis service offered by Google Inc. Through these cookies iAgenda gets insight into its website visit. Think of visitor numbers, popular pages and topics. iAgenda cannot see who (which PC) visits its website. iAgenda has one editorial agreement with Google, has turned off "data sharing" with Google and does not allow Google to process the full IP address. More information can be found here .
Google Adsense iAgenda is funded with advertisements from Google. Cookies make advertising more effective. Without cookies it is for an advertiser harder to reach its target audience or find out how many ads have been shown and how many clicks have been generated. You can find more information here .

The cookies allow:

Due to the operation of HTTP and the security around cookies, it is not possible for the relevant first party - in our example iAgenda - to send third party influence cookies.

What are cookies used on iAgenda?

Cookies make it possible to retrieve information from previous visits during follow-up visits. In practice, this is used to keep track of that you are logged in, that you have made certain settings and that you have seen certain site elements before. Cookies that adapt the functioning of the site to your wishes are called functional cookies .

In addition, cookies can also be used to let the site know that a visitor has previously visited the site. In this way statistical data on the use of  the website are collected. A well-known example of this is Google Analytics. Hereby only anonymised statistical information is used which is used by us to analyze and improve the functioning of the site. Information about your visiting behavior may also be used to tailor advertisements to your interests. iAgenda only uses anonymized information about pages that you have previously visited on iAgenda.

The visitor profiles that iAgenda creates itself with the help of first party cookies, will never be shared with third parties and will only be used for quality and relevance to improve iAgenda.

What cookies does iAgenda use?

Tracking cookies

Tracking cookies are placed by us on your equipment so that we can recognize your computer when you visit us again. There are two types of tracking cookies: session cookies and permanent cookies. With session cookies we can see which parts of the website have been viewed on your computer during a visit. With permanent cookies we can recognize your computer if you visit our website again later.

Tracking cookies with our advertisements

With tracking cookies, we collect information about where you saw the ads and which ads you clicked.


Cookies are placed through our website by the companies Adobe and Google. We use these cookies to gain insight into the use of our website so that we can improve our website.

Other / unforeseen cookies

Due to the way the internet and websites work, we may not always have insight into the cookies placed by third parties through our website. This is particularly the case if our web pages contain so-called 'embedded elements', such as texts, documents, images or videos that are stored with another party, but which are displayed on, in or via our website.

Do you come across cookies on our website that fall into this category (and that is why we have not mentioned above)? Let us know or contact the relevant third party directly and ask which cookies they have placed, the reason for their placement, the life of the cookie (s) and how your privacy is guaranteed.


This overview of cookies on is a snapshot. iAgenda strives to keep this list as up-to-date as possible. However, due to the non-static nature of the internet and the many (external) parties involved, it is possible that not all current cookies and / or sites can be found in this overview immediately.

How can I refuse cookies?

Without cookies, it is almost impossible for us to give you as a visitor the best experience when visiting the site. That has to do with analyzing the web statistics to determine what the site should look like and navigate, but also to determine what content is popular and what is actually not read by our visitors.

In addition, as mentioned, we also need cookies to serve advertisements. Without advertising revenue, it is not possible to keep the site as it currently exists free of charge and further develop it.
