Cookie policy
This page explains what this site stores in your browser when you visit, what we use it for, and how you can say yes, say no or change your mind at any time.

What a cookie is
A cookie is a very small file that a website leaves on your computer, tablet or phone when you visit it. It is not a program, it cannot reach into your files and it does nothing on its own: it simply holds a short piece of information that the site reads again later, for example to know that you have been here before.
Browsers also have other, similar drawers, such as what is called local storage. For what matters here they work the same way —they keep a piece of information on your device— so this page covers them in the same detail and with the same care as cookies.
Exactly what this site stores
Until you accept, this site stores no cookies and asks Google for nothing: the measurement script is not even downloaded. If you accept, the first two rows of this table are stored. The third is the one that remembers your choice, and the fourth only appears if a contact form submission does not go through.
The table scrolls sideways to show every column.
| Name | Who sets it | What it is for | How long it lasts |
|---|---|---|---|
| _gaCookie | Google (third party) | Tell one visitor from another, so we can count how many people come in and which pages they read. | 2 years |
| _ga_<ID de propiedad>Cookie | Google (third party) | Keep track of the current visit (when it starts and ends) for those same statistics. | 2 years |
| elyra:analytics-consentLocal storage | Elyra (first party) | Remember whether you accepted or declined analytics, so we do not ask again on every page. | 12 months |
| PHPSESSIDCookie | Elyra (first party) | Only when a contact form submission does not go through: it holds what you had written so the form comes back filled in rather than empty. | Until you close your browser |
And what we do not do
This list matters as much as the table above, because it is what most websites do:
- There are no advertising cookies, and none of the kind that follow you from site to site to show you ads.
- We do not personalise anything based on what you read, we do not build profiles and we do not make automated decisions about you.
- There are no social network pixels or buttons. The Instagram and Facebook links in the footer are ordinary links: they load nothing from those networks unless you click them.
- We do not sell this data and we do not pass it on to anyone. Besides us, the only party that handles it is Google, which provides the measurement service.
- When you accept, we expressly ask Google to keep advertising storage, ad user data, ad personalisation and cross-device measurement switched off. That is not a promise on our part: they are four settings written into the code of this site.
- And your choice is not kept in a cookie but in the local storage of your browser: that way it does not travel with every request, it stays on your device.
On what grounds we use them
The two analytics cookies are only installed if you accept them. That is what article 22.2 of Spanish Act 34/2002 on information society services (LSSI-CE) and article 6.1.a) of the General Data Protection Regulation require: your consent, freely given, before anything is stored.
Here that is followed to the letter: until you press "Accept", the Google measurement script is not downloaded and not a single piece of data is sent. Declining closes no doors —the site works exactly the same— and we do not ask you for a reason.
The other two rows in the table do not need your permission because they are strictly necessary, which is the exception that same article 22.2 provides for. One holds the choice you have just made —without it we would have to ask you again on every page, which is precisely what nobody wants— and the other brings back what you had written in the form when a submission does not go through.
Does my data leave Europe?
If you accept analytics, your browsing data is handled by Google, and Google may handle it in the United States, where Google LLC is based. That is an international data transfer, and we are saying so plainly.
That transfer currently relies on the adequacy decision the European Commission adopted on 10 July 2023 on the EU-US Data Privacy Framework: the Commission considers that US companies certified under that framework offer protection equivalent to European protection, and Google LLC states that it is certified. The General Court of the European Union confirmed that the decision is valid on 3 September 2025 (case T-553/23), as the Spanish Data Protection Agency itself reported.
Google also states that it applies the standard contractual clauses approved by the European Commission for anything that decision does not cover. Were the framework to stop being valid, we would review this page before carrying on measuring.
You can check it for yourself:
How to accept, decline or change your mind
The first time you visit, the site asks you with a notice at the bottom of the screen. Both buttons are the same size and the same colour: accepting and declining cost exactly the same, and that is deliberate.
After that you can change your mind whenever you like with the "Cookie preferences" button at the end of any page, including this one: it opens that same notice again, with both options.
If you decline, on top of loading nothing we delete any Google cookies left over from an earlier permission. Either way your choice is remembered for twelve months: after that we ask you again.
From your browser
You can also see, delete or block the cookies from this site —and from every other site— in your browser itself. Each one explains how on its own help page:

- Mozilla Firefox (opens in a new tab)
- Safari (opens in a new tab)
- Microsoft Edge (opens in a new tab)
And if you would rather Google Analytics did not measure you on any website at all, Google publishes a browser add-on that switches it off everywhere at once.

Regarding your personal data you may ask us for access to it, ask us to correct it if it is wrong, ask us to erase it, ask us to restrict how we handle it, object to us handling it, and ask for it in a format you can take elsewhere. Just write to us.
Since we ask for no name and no identifying detail in order to measure browsing, we may need some further information to find which data you are referring to. Withdrawing consent takes effect immediately and does not affect what was measured before, which was lawful while you had given it.
And if you believe we have not handled your request properly, you can lodge a complaint with the Spanish Data Protection Agency, the supervisory authority in Spain.

If what the site stores ever changes, we will update this page and ask you again: the permission you give covers what we describe here, not whatever might come later.
