2) What are cookies?
Cookies are small text files placed on your device (computer, tablet, smartphone) when you visit a website. We may also use similar technologies such as local storage, pixels, tags, or SDKs which serve comparable purposes.
3) Why we use cookies
For convenience, we group cookies by their general uses below. These categories are intended to help explain how different types of cookies may be used on our Website and Tours Site. Cookie use can vary depending on configuration, and other websites you visit may categorize cookies differently than we do.
A) Essential (strictly necessary) cookies
Some cookies are essential for our Website/Tours Site to function properly and securely. They support core operations such as:
-
enabling page navigation and basic site functionality,
-
maintaining security and preventing misuse,
-
ensuring service stability (e.g., load balancing),
-
remembering choices that are required to deliver a service you request.
Without these cookies, the Website/Tours Site may not be available to you and these cookies cannot be switched off in our systems. They are generally set only in response to actions you take, such as requesting core site services or adjusting key settings. These cookies do not store information that directly identifies you.
B) Performance / Analytics (audience measurement) cookies
These cookies help us measure and improve the performance of our Website/Tours Site. They allow us to understand how visitors use our pages, for example:
-
which pages are most popular,
-
how visitors move through the site,
-
how long pages take to load and whether errors occur,
-
what types of devices and browsers are used.
We use Google Analytics 4 (GA4) for audience measurement. These cookies may process technical information such as IP-derived information and may generate unique identifiers so we can analyze usage trends and improve our content and user experience. Where required by law, we only activate analytics cookies after you consent via the cookie banner.
C) Functional (preference) cookies
These cookies enable enhanced functionality and personalization. They may be set in response to actions you take, such as:
-
saving your privacy preferences,
-
remembering language choices or interface settings,
-
remembering form inputs to avoid re-entering information.
Functional cookies may be set by us or by third-party providers whose features we have added to our pages. Although these cookies are not strictly necessary, if you disable them, certain features may not be available or may not work as intended.
D) Targeting / Marketing (advertising) cookies
Targeting cookies are used by advertising and marketing partners to help deliver and measure advertising. They work by uniquely identifying your browser/device and may be used to:
-
measure campaign performance and conversions,
-
limit how often you see an ad,
-
build audiences for remarketing (showing our ads to people who have previously visited our site),
-
personalize advertising on other websites.
We may use Google Ads and related tagging to support advertising measurement and targeting activities. Where required by law, we only activate marketing/targeting cookies after you consent via the cookie banner.
Your choices: If you delete, block, or disable cookies, you may not be able to access certain features, and parts of the Website/Tours Site (such as preference settings, referral links, or integrations with third-party services) may not work or may not work as intended. You can manage your choices at any time using the cookie banner/settings link (where provided) or through your browser settings.
4) Third-party cookies (Tours Site)
The Tours Site may embed or rely on third-party services (for example, the 3D tour player and associated scripts, and the overlay platform MP Skin). Those providers may place cookies or process technical information under their own terms. Where required, we request your consent before enabling non-essential third-party cookies.
5) Your choices (consent, refusal, withdrawal)
When you first visit the Website or Tours Site, a cookie banner lets you:
-
Accept all cookies
-
Refuse non-essential cookies
-
Customize your choices by category
Rejecting cookies should be as easy as accepting them.
You can change your choice at any time via:
-
Cookie settings link: [ADD YOUR “COOKIE SETTINGS” LINK OR BUTTON LOCATION]
or by clearing cookies/site data in your browser settings.
Refusing non-essential cookies will not block access to the Website/Tours Site, but some optional features and measurement may be limited.
6) Cookie retention
Cookies are stored for a limited duration depending on their purpose. For audience measurement configurations relying on French guidance/exemptions, recommended limits are commonly referenced as up to 13 months for cookie lifetime and up to 25 months for related analytics data retention (when those exemption conditions are met).
