Cookie policy
We explain simply what this website stores in your browser, why, and how you can change it. As of 26 October 2026.
Key points
- We do not use advertising cookies or cookies that track you across the internet.
- By default the website stores only one piece of information – your cookie choice.
- The Google map on the contact page loads only after your consent, because Google stores its own cookies with it.
- You can change your consent at any time: (the link is also in the footer of every page).
What are cookies
Cookies are small text files that a website stores on your device. Browser storage (localStorage) works in a similar way. Under Polish law – Article 399 of the Electronic Communications Law – consent is required to store such information, unless it is necessary to provide a service you have requested.
What we store and when
| Type | Provider | Purpose | Duration | When |
|---|---|---|---|---|
| Cookie consent choice (browser storage, name: md_cookie_consent) | MDgroup Sp. z o.o. | remembering what you agreed to, so we don’t ask on every visit | 12 months or until browser data is deleted | always – necessary |
| Google Maps cookies | Google Ireland Limited | displaying the interactive directions map, map security and settings | according to Google’s policy | only after “Maps and external content” consent |
Details about Google cookies can be found in Google’s policy.
External resources without cookies
To display the animated background, your browser downloads a library from an external provider. No cookies are stored, but – as with any internet connection – the provider receives your device’s IP address. The fonts (Verdana and Arial) are built into your device’s system and are not downloaded from outside.
| Resource | Provider | Why |
|---|---|---|
| Background animation library (three.js) | cdnjs – Cloudflare, Inc. | animated cubes in the background |
Zencal booking calendar
We use the Zencal calendar (zencal.io) to book consultations. As instructed by Zencal, the calendar script loads together with the page so that it is ready when you click a consultation button. The calendar runs on Zencal’s servers, which may store cookies needed for bookings to work. Data you enter when booking (e.g. name, email, phone) reaches us via Zencal. Details can be found in Zencal’s privacy policy.
WhatsApp chat
The chat button on the website does not load any WhatsApp scripts or cookies. Only when you click “Message us on WhatsApp” do you go to the WhatsApp app or WhatsApp Web, where the privacy rules of WhatsApp Ireland Limited (Meta) apply. The website only remembers, until you close the browser tab, that the chat window has already been opened (session storage, name: md_wa_seen).
Managing your consent
How do I change or withdraw consent?
Click “Cookie settings” in the page footer or . Withdrawing consent does not affect the lawfulness of what happened before it was withdrawn.
Can I block cookies in my browser?
Yes. Every browser lets you delete and block cookies and site data in its privacy settings. After deleting the data the website will ask for your consent again.
What if I don’t give consent?
The website works fully. Instead of the map you will see an “Open in Google Maps” button that takes you to the map in a new tab.
