What data do we process through this website?
This website is an informational website: you cannot create an account on it or make an appointment through it. You make an appointment by phone or email with the Eisenhower Kliniek — not through this website. See the page on making an appointment.
During a normal visit to the website, we do not process any personal data that you enter yourself, unless you use the contact form (see below). However, as with virtually every website, standard technical data is processed by our hosting provider and by Supabase (the party that stores and delivers the content of this website), such as your IP address and technical request data — necessary to make the website work and to keep it secure. This data is not used for marketing purposes and is not sold to third parties.
Contact form
You can send us a message using the contact form. To do so, we ask for your name, your email address and your message. We use this data solely to answer your question.
Your message is forwarded as an email to Dr. Jansen's practice via the email service Resend. It is not stored in the website's database.
To prevent abuse by spam bots, we keep your IP address for at most 24 hours. This allows us to limit how many messages can be sent from a single address.
The form is not intended for medical questions. Please do not share any medical information in it: we cannot respond to such questions through this form.
Cookies
No cookies are placed for ordinary visitors to this website. Only the restricted management area, intended exclusively for practice staff, uses a necessary login cookie. More details are available on the cookie and disclaimer page.
Visitor statistics
To see how the website is used and to improve it, we keep anonymous visitor statistics: which pages are viewed, which website you came from, the type of device and browser, the country (derived by our hosting provider) and clicks on, for example, phone numbers, links and videos. In doing so:
no cookies are placed and nothing is stored on your device
your IP address is not stored; to count visitors per day, we create an irreversible code from your IP address and browser combined with a secret key that is replaced every day and then deleted, so you cannot be followed across multiple days
the data is not shared with third parties and is not used for advertising or profiling
These statistics are only visible to the administrators of the website.
Sharing with third parties
We do not share data with third parties for commercial purposes. For hosting and storing the website, we use professional service providers (including Supabase for storing the website and Resend for sending messages from the contact form), who apply appropriate technical and organisational security measures.
Retention period
We do not keep personal data for longer than necessary. Messages sent through the contact form are kept for as long as needed to handle your question. The IP address used for spam protection is deleted after at most 24 hours. Technical server logs are not retained for longer than is needed for security and troubleshooting purposes. The anonymous visitor statistics are automatically deleted after at most five years.
Security
We take appropriate technical and organisational measures to protect your data against loss or unlawful use, including encrypted connections (https) and access security for the management area.
Your rights
Under the GDPR (General Data Protection Regulation), you have the right to access, rectify, erase and port your own personal data, and the right to object to its processing. Apart from messages you send through the contact form, we do not record any personal data about you through this website. If you do have a question about your data, for example in connection with your treatment at the Eisenhower Kliniek, please contact us using the details above.
If you disagree with the way we handle your data, you can file a complaint with the Dutch Data Protection Authority (Autoriteit Persoonsgegevens).
Changes
We may update this privacy policy from time to time, for example if something changes in how the website operates. The date of the most recent change is shown below.
