A cookie is a small text file deposited in your browser when you visit a website. It allows your browser to be recognised on a subsequent visit, or to transmit information to a third-party service.
All analytics cookies on this website require your explicit consent before being activated. No analytics or tracking cookie is placed without your prior agreement.

3. What are these tools for?
Google Analytics 4
Google Analytics measures audience data in aggregate: number of visitors, most-visited pages, traffic sources (organic search, direct links, social networks), session duration. IP addresses are anonymised by default in GA4. Data is hosted by Google LLC (United States), governed by standard contractual clauses from the European Commission.
Contentsquare (formerly Hotjar)
Contentsquare records individual browsing sessions: mouse movements, clicks, scrolling. These recordings help identify friction points on the website and improve the user experience. Form fields are masked — no entered data (name, email, message) is recorded. Data is hosted by Contentsquare SAS, headquartered in France.
4. Managing your preferences
You can change your choice at any time. Clicking "Decline" immediately disables Google Analytics and Contentsquare for future visits.
Via your browser
You can block or delete cookies directly from your browser settings:

5. Consent retention
Your choice is stored for 13 months in your browser's local storage (localStorage). After this period, the banner reappears to collect a new consent. Clearing your browser cache or browsing data will erase this choice.
