Cookie Policy

Last updated: September 2026

This is an informative English translation. The legally binding version of this document is the Spanish original, available at www.polaristechgroup.com. In the event of any discrepancy, the Spanish text prevails.

01What are cookies?

Cookies are small text files that a website places on the user's browser or device when they visit it. They are used to make websites work correctly, to remember user preferences and to provide information to site owners. Cookies are sent by the server to the browser and returned by the browser on every subsequent request.

02Strictly necessary cookies

Essential for the site to work. They do not require consent (art. 22.2 LSSI-CE):

CookiePurposeDuration
__sessionUser session generated by Next.js. Required for basic operation.Session

03Analytics cookies (with consent)

These are only installed if the user expressly accepts them through the consent banner. Their purpose is to measure use of the website in an aggregated and anonymous way in order to improve the experience. They are never used for advertising or individual profiling. Legal basis: consent of the data subject (art. 6.1.a GDPR).

CookieProviderPurposeDuration
_gaGoogle Analytics 4Distinguishes unique users. Stores an anonymous identifier.2 years
_ga_RQBTF58CJQGoogle Analytics 4Maintains the analytics session state.2 years

You may withdraw your consent at any time by deleting the cookies from your browser. The preference is stored in localStorage under the key polaris-cookie-consent.

04Local storage (localStorage)

In addition to cookies, this website uses the browser's local storage (localStorage) to save user preferences. localStorage differs from cookies: the data is not sent to the server on each request and remains solely on the user's device.

KeyPurposeDuration
polaris-cookie-consentRecords whether the user has accepted or rejected analytics cookies.Until the user deletes it
announcement-banner-closedRecords whether the user has dismissed the announcement banner at the top so it is not shown again.Until the user deletes it

This data is stored exclusively on the user's device and is never transmitted to any server or third party. The site language is not stored: it is part of each page's address.
