What are cookies?

Cookies are small text files that a website stores on a user's device when they visit it. They allow the site to remember actions or preferences across a session or between visits.

What cookies does this site use?

This site uses analytics. summumia.es uses Google Analytics 4 through Google Tag Manager to measure traffic in aggregate form. Those cookies are only set if you accept them: until then consent is denied by default (Google Consent Mode v2) and no measurement cookie is loaded. You can reject them, and change your mind at any time from the link at the end of this page.

The only cookies this site may set are technical in nature, needed for the contact form to work correctly:

Name Category Duration Purpose
PHPSESSID Technical Session (deleted when the browser is closed) Identifies the user's PHP session while the contact form is submitted. It does not store personal data and is not used for tracking.
_ga Analytics 2 years Google Analytics 4. Distinguishes users in pseudonymised form to measure visits. Controller: Google Ireland Limited, with processing by Google LLC (USA). Only set with your consent.
_ga_6M8S8YHGTG Analytics 2 years Google Analytics 4. Keeps the session state for property G-6M8S8YHGTG. Same controller and same consent condition.
summum_consent Technical Until you delete it Not a cookie: it is a value stored in your browser's local storage (localStorage). It remembers whether you accepted or rejected, so we do not ask again. It never leaves your device.

International data transfers

Analytics cookies involve a transfer of data to Google LLC in the United States. That transfer relies on the EU-US Data Privacy Framework (European Commission adequacy decision of 10 July 2023), to which Google LLC is certified, and on the standard contractual clauses included in Google Ireland Limited's data processing terms. If you reject analytics cookies, this transfer does not take place.

This cookie does not require consent because it is strictly necessary to provide the service requested (art. 22.2 of Spain's LSSI-CE and recital 30 of the ePrivacy Regulation).

How to withdraw or change your consent

Your choice is stored in your browser and you can withdraw or change it at any time, as easily as you gave it: use the manage cookies link and choose again. Once withdrawn, measurement cookies are no longer set. You can also delete the cookies already stored from your browser, as explained below.

Managing cookies in your browser

You can configure your browser to block or delete cookies at any time. Note that disabling technical cookies may prevent the contact form from working correctly. Instructions for the most common browsers:
