  1. Introduction

    The European Spallation Source ERIC (“ESS”, “us”, “we”, “our”) uses cookies on (the "Website"). By using the website, you consent to the use of cookies.
    Our Cookies Policy explains what cookies are, how we use cookies, your choices regarding cookies, and further information about cookies.
  2. What are cookies?

    Cookies are small pieces of text sent by your web browser to a website you visit. A cookie file is stored in your web browser and allows the website or a third-party to recognise you and make your next visit easier and the website more useful to you.

    We use “essential”, “session”, and “first-party” cookies:
    • Essential cookies are used to authenticate users and prevent fraudulent use of user accounts. These expire at logout or after a maximum of 24 days.
    • Session cookies do not collect information from your computer and are not retained after the browser is closed.
    • First-party cookies remember you when you return to a previously visited site, are created by the website, and are saved on the device from which you have accessed the website.
  3. Third-party affiliates

    In addition to our own cookies, we also allow third-party affiliates, including Google Analytics and Hotjar, to use first-party cookies in order to report usage statistics and to distinguish one website visitor from another.

    We use Google Analytics to measure how users interact with our website content. As you navigate between web pages, Google Analytics provides us with JavaScript tags (libraries) to record information about the page you have seen (for example, the URL of the page). The Google Analytics JavaScript libraries use HTTP Cookies to "remember" what a user has done on previous pages on/interactions with the website. These first-party cookies are used to distinguish users, determine which domain to measure, throttle the request rate, remember traffic source information, determine the start and end of a session, and remember the value of visitor-level custom variables. For further details, please see Google Analytics Cookie Usage on Websites by clicking on this link, and Google’s privacy policy by clicking on this link.

    We also use Hotjar to ensure a user-friendly website and to better understand our users’ needs. Hotjar is a technology service that helps us better understand our users’ experience (e.g. how much time they spend on which pages, which links they choose to click, what users do and do not like, etc.) and this enables us to build and maintain our service with anonymous user feedback. Hotjar uses cookies and other technologies to collect data on our users’ behaviour when navigating our website. This includes data collected about our users’ devices (in particular, a device's IP address [captured and stored only in anonymised form], device screen size, device type [unique device identifiers], browser information, geographic location [country only], and preferred language used to display our website). Hotjar stores this information in a pseudonymised user profile. Neither Hotjar nor ESS will ever use this information to identify individual users or to match it with further data on an individual user. For further details, please see Hotjar’s privacy policy by clicking on this link.
  4. How long are cookies stored?

    You may delete cookies at any time via your device’s web browser. Automatic expiration periods are as follows:
    • Google Analytics cookies expire after two years and 24 hours.
    • Hotjar cookies expire after 365 days.
  5. What are your choices regarding cookies?
