Cookie statement
Our websites use cookies from us and from third parties. Cookies are small information files that are automatically stored on, or read from, a visitor’s device when they visit a website. This happens through the web browser on the device. For example, your computer, tablet or smartphone. On this page, you can read more about cookies.
When a website places cookies, the visitor usually has to give permission. Do we use cookies that do not store information about visitors? For example, cookies that only track visitor numbers? Then we do not need to ask for permission. We do have to let you know that we use cookies.
Functional cookies
Some cookies are needed for the website to work. These are functional cookies. They let you view the details of old and new vaccination appointments, for example. The cookies also help keep the system secure. The system places the cookies when you visit the website for the first time. They become active again when you return to the website.
Analytical cookies
Some cookies are needed to make the website work better. These are called analytical cookies. These cookies store no information, or very little information, about you. You do not need to give permission for these cookies.
GGD GHOR Nederland thinks your privacy is important. That is why we remove part of your IP address before we store it. This lets us see what our visitors do. But not who our visitors are.
The cookies collect the following data about you:
- part of the IP address
- the Cookie ID. This is a random number that makes sure the cookies work properly.
- the website you came from, for example Google
- which equipment and software you use
- which links you use to reach our website
- which links you click on the website
- which search terms you use in the website search engine
We collect this data to improve this website. In the table below, you can see exactly which analytical and functional cookies we collect and why. And how long we keep them.
| Cookie name | Retention period | Purpose |
| _pk_id – | 13 months | This cookie gives each visitor a number. This lets us recognise our visitors without storing their IP address. |
| _pk_ref – | 6 months | This cookie stores information about the page you use to reach our website. For example Google. |
| _pk_ses– | 30 minutes | This cookie gives each visit a number. This lets us link all actions of the visitor to the same visit. |
| _cfduid | Immediately after closing the website | This cookie makes sure that we only allow real users to our website. This helps us keep the website from going down because of fake users. |
| SessionId_{nr} | Immediately after closing the website | This cookie makes sure that the website works properly. It keeps your data stored on the web page for a short time. This is for the pages you use before you log in with DigiD. This lets you go back to another page. Your data will not be lost then. Your data is deleted when you close the web page. The cookie is removed from your computer when you close the website. |
| piwikGroupAndCat | Until the visitor clears browser storage | We use the year of birth to study how different age groups use our website. For example, we look at whether older visitors stop sooner, whether some steps are less clear to them, and what this means for the number of calls to our customer service team. These insights help us improve the website in a targeted way, so that all visitors, including older users, can find the information better and make appointments more easily. We only process the year of birth, not the full date of birth. |
| piwikPC4 | Until the visitor clears browser storage | We use the first four digits of your postcode (postcode 4) to understand how well our appointment suggestions match the needs of visitors in different areas. For example, we look at which location people choose and whether they can complete making an appointment without problems. By linking postcode 4 to the suggested locations and days, we can see whether the options in an area match the need well. This is important because many locations are open on only one day a week, for example. With this information, GGD’en can identify problem locations more quickly and take action where needed. We only process the first four digits of the postcode, not the full postcode. |
