I. What are Cookies?
Like most websites you visit, our Website uses Cookies and other similar technologies described below (collectively referred to as “Cookies”).
Cookies are small text files that collect information about visits to the Website or a user's use of an application, such as the Internet Protocol (IP) address, how the Website was accessed (for example, through a search engine or a link from another website) and how users navigate the Website or mobile application. Similar technologies (such as “tags”) perform the same functions in similar circumstances.
Cookies collect information about you, your data, your preferences or your device, mainly in order to personalise your browsing experience. This tool helps you find information more easily and tailors content or marketing activities to you.
Cookies help store user preferences for certain information, allowing us to analyse how the Website is used and which pages are visited in order to improve its functionality.
Cookies are classified by purpose (what they are used for) and by duration (how long they interact with you).
Some of these Cookies are set by us and others are set by third parties (for example, analytics service providers, etc.).
II. How do we use Cookies?
We use different types of Cookies on our Website for the various purposes set out below:
1. Strictly Necessary Cookies
These Cookies are necessary to enable you to access the Website and use its related features, and to browse securely, including but not limited to setting your language or location preferences or completing forms.
You can configure your browser to block or alert you about these Cookies, but if you do so, some parts of the Website will not function properly.
2. Functional Cookies and Analytics Cookies
Unlike strictly necessary Cookies, these are non-essential Cookies: they are set only after we have obtained your consent, and you may enable, disable or change your choices at any time through the Cookie Consent Manager. The purpose of this category is to improve how the Website operates and to help us better understand user behaviour.
Analytics Cookies serve measurement and statistical purposes: they record the number of visits, the paths users take, and the level of user interaction across the different areas of the Website. On the basis of the aggregated data obtained, we assess the performance of the Website and test and refine our content, features and layout in order to continuously improve the quality of our services.
Functional Cookies retain your settings and choices across browsing sessions, allowing the Website to remember your usage habits and deliver a seamless, personalised experience - for example, by remembering the language or region you have selected.
3. Third-Party Cookies
Certain features embedded in the Website rely on Cookies set by third parties. These Cookies are placed on your device only at the point when you actively use the corresponding feature, and fall outside the scope of our Cookie Consent Manager. At each location on the Website where this applies, and to the extent that the law of your place of residence requires consent, we will inform you in advance that a third party will set Cookies; by clicking to use the feature, you are taken to consent to the setting of those third-party Cookies. If you decline, certain features may become unavailable. In any event, you may still disable or delete these Cookies through your browser settings, as explained below.
A typical example is our embedding of the YouTube video player: YouTube will set Cookies on your device as soon as you click to play a video. For this feature, we enable YouTube's "privacy-enhanced mode" in order to limit Cookies that track your viewing behaviour and that may personally identify you. Similarly, the Website integrates Google Maps to display our location. When you interact with the embedded map, Google may set Cookies and collect certain data, such as your IP address, so that the map displays and functions correctly. This processing is governed by Google's privacy policy.
Similarly, the Website may integrate social media sharing features - such as Facebook's "Like" button, the "Post" button on X (formerly Twitter), or LinkedIn's "Share" button. When activated, these buttons may collect your IP address and information about the page you are visiting, and may set Cookies or use similar technologies to operate; as above, they only function when you interact with them directly. We do not control how these social media networks collect and use your data -such processing is governed by each platform's own privacy policy, which you can review on the relevant platform's website or through the links provided in our Cookie Consent Manager.
4. Cookies on the Careers Area (Career Site)
Our careers/recruitment area is operated on the Teamtailor platform and exists as a separate site, distinct from the rest of the Website. When you access this area to browse job opportunities or submit an application, Teamtailor will set its own Cookies on your device.
The Cookies on the Careers Area include Cookies necessary for the site to function and to process your application, together with analytics or marketing Cookies that are activated only after your consent. In addition, certain third-party Cookies may appear if you use features integrated there, such as applying via LinkedIn or watching a video embedded in a job posting.
These Cookies are not managed through the Cookie Consent Manager on our main Website. Instead, they are governed by the separate consent mechanism and Cookie Policy displayed directly within the Careers Area. You may view, adjust or withdraw your consent at any time through the cookie management function at the foot of the careers pages, or through your browser settings as explained below.
III. How can you control Cookies?
Except for Cookies that are strictly necessary for the operation of the Website, we only place Cookies on your device after receiving your express consent through the Cookie banner you will see when you first visit our Website, or through the Cookie Consent Portal. You have the right to refuse and may withdraw your consent at any time; withdrawal of consent does not affect the lawfulness of processing carried out on the basis of consent before the withdrawal.
Please note that certain functions embedded in the Website require Cookies from third parties to be set in order to work. These Cookies are only set when you interact with that function.
Cookie Consent Portal:
We provide a tool on our Website called the “Cookie Consent Portal”. You can change your Cookie preferences (except for strictly necessary Cookies) at any time by clicking the buttons in the Cookie Consent Portal. You can find the Cookie Consent Portal on the Website whenever you visit; however, there may be occasions when the portal is unavailable (for example, downtime, errors, JavaScript disabled, etc.). In that case, you can change your Cookie preferences in your browser, as explained below.
Your browser:
You can change your Cookie preferences by changing your browser settings. Most web browsers accept Cookies, but you can usually change your browser settings to refuse new Cookies or to disable existing ones.
To do this, follow the instructions provided by your browser (usually found under “Help”, “Tools”, “Settings” or “Edit”). We provide links to the “Help” sections of some of the most common browsers below:
- Microsoft Edge: https://support.microsoft.com/en-us/microsoft-edge/delete-cookies-in-microsoft-edge-63947406-40ac-c3b8-57b9-2a946a29ae09
- Safari: https://support.apple.com/kb/PH5042
- Chrome: https://support.google.com/chrome/answer/95647?hl=en
- Firefox: https://support.mozilla.org/en-US/kb/enable-and-disable-cookies-website-preferences
- Opera: https://help.opera.com/en/latest/web-preferences/#cookies
For more information about how Cookies and targeted marketing work, you can visit: https://www.youronlinechoices.eu.
For mobile applications or devices, you can change your privacy settings in your phone's settings and application management. Please note that tracking and notification mechanisms in mobile applications may differ from those on the Website.
Please note that the opt-out choices described above only apply to the specific browser or device on which you make them; you will therefore need to opt out separately on all of your browsers and devices.
In addition, when you disable a Cookie or a group of Cookies, this only stops the Cookie from continuing to operate; it does not delete Cookies already stored on your device. If you want to remove them completely, you need to do so in your browser settings.
Please also note that your opt-out choice is itself saved by a Cookie. Therefore, if you delete all Cookies in your browser, the Cookie recording your opt-out will also be deleted. The system will then no longer “remember” that you opted out, and you will need to opt out again if you still do not wish to receive certain types of Cookies.
IV. How long do Cookies last?
Session Cookies:
These are temporary Cookies that are automatically deleted after you close your browser (or when your browser session ends).
Persistent Cookies:
These are Cookies that are stored until you or your browser deletes them, depending on the Cookie's expiry (the duration or lifespan of a Cookie may vary according to its purpose).
V. Changes to our use of Cookies
We may amend and supplement the scope and the manner in which Cookies are used on the Website in line with changes in technology, operations or applicable legal requirements.
Any adjustment to the list of Cookies deployed on the Website will be updated promptly in the Cookie Consent Portal – where you can review and reset your consent choices.
Where necessary, these changes will also be reflected in the Cookie Policy, which is updated from time to time. For material changes – for example, the addition of a new processing purpose or a new group of Cookies that collects your personal data – we will apply proportionate notification measures to ensure that you are informed before those changes take effect.
We recommend that you periodically review the current version of the Cookie Policy published on the Website so that you always understand how we use Cookies at the time of your visit.
