Our own cookie-free visitor measurement
We also measure website traffic with our own cookie-free measurement, to see how many people visit, which pages they view, where they come from (for example Google search or an ad), and how many bookings and phone-call clicks happen. No cookie is set and nothing is stored on your device.
- What we record: the page viewed, the time, the referring site or campaign, the device type (mobile, computer, tablet) and the country. For a booking: the chosen treatment, the doctor and the booking ID, without name, phone number or email address.
- We do not store your IP address: it is only used to count unique visitors with a code that changes every day and cannot be reversed. You cannot be identified from it.
