What cookies are
A cookie is a small file a website stores in your browser to remember information between visits. This site uses only two strictly necessary cookies, needed for it to work, and two analytics cookies, which are installed only if you expressly accept them in the banner.
We use no advertising, profiling or social-media cookies, and we do not sell or share the data with third parties for commercial purposes.
Cookies we use
| Cookie | Provider | Purpose | Duration | Type |
|---|---|---|---|---|
| _ga | Google LLC | Distinguishes unique users by assigning a random identifier. | 2 years | Analytics |
| _ga_VY96PX1WGY | Google LLC | Keeps the Google Analytics 4 session state. | 2 years | Analytics |
| cookie_consent | 18xx.cat | Remembers whether you accepted or rejected analytics cookies. | 1 year | Necessary |
| site_lang | 18xx.cat | Remembers the language you chose to browse the site. | 1 year | Necessary |
How to change your choice
Until you accept, Google Analytics runs in denied-consent mode and writes no cookies to your browser. You can change your decision at any time from the Cookie settings link in the footer. If you reject analytics cookies after having accepted them, any that Google Analytics had already set are deleted automatically.
You can also delete or block them from your browser settings (Chrome, Firefox, Safari or Edge). Note that blocking the strictly necessary cookies will stop the site from remembering the language you chose or your answer about cookies.
International transfers
The analytics cookies are managed by Google LLC, based in the United States, acting as data processor. This may involve an international transfer of data outside the European Economic Area.
Google is certified under the EU-US Data Privacy Framework and, as an additional safeguard, applies the standard contractual clauses approved by the European Commission. You can read how Google handles data at policies.google.com/privacy.
