Cookie Policy (EU)
This cookie policy was last updated on 25 August 2026 and applies to citizens and permanent legal residents of the European Economic Area and Switzerland.
This English text is a translation provided for convenience. In the event of any discrepancy, the Spanish version of this policy prevails.
1. Introduction
This website uses a minimal set of cookies and related technologies. This page explains exactly which ones, what they do, and how long they last. We do not use advertising cookies, we do not build visitor profiles, and we do not share browsing data with advertising networks.
2. What is a cookie?
A cookie is a small file sent with the pages of this website and stored by your browser on your device. The information stored can be returned to our servers, or to the servers of the relevant third party, on a later visit.
3. Cookies used on this website
This site sets one cookie. It is strictly necessary for a function you asked for — remembering your language — and under Article 5(3) of the ePrivacy Directive a cookie of this kind does not require consent. That is why you are not shown a cookie banner.
| Name | Provider | Expiry | Purpose |
|---|---|---|---|
| NEXT_LOCALE | perseispace.com (first party) | 1 year | Remembers which language you chose so the site opens in it next time. Set only when you select Spanish or open a Spanish URL. |
4. Analytics
We use Vercel Web Analytics to count page views and understand which pages are read. It is cookieless: it stores nothing on your device, does not identify you, does not follow you across other websites, and reports only aggregated figures. Because it neither stores nor accesses information on your device, it falls outside the consent requirement for cookies.
5. Embedded video
Some pages embed video from YouTube in privacy-enhanced mode (youtube-nocookie.com). Loading a page that contains a video sets no cookies. If you press play, YouTube may then set cookies on the youtube-nocookie.com domain, governed by Google’s privacy policy rather than this one. If you do not play the video, no YouTube cookie is set. Google privacy policy.
6. Forms
The contact and datasheet forms send your message to us by email through our processor, Resend. They set no cookies. How we handle the personal data you submit is described in our data protection notice. Data protection.
7. Enabling, disabling and deleting cookies
You can use your browser to delete cookies automatically or manually, to block them, or to be warned each time one is set. Your browser’s help section explains how. Because the only cookie this site sets is the one that remembers your language, blocking it will not break the site — it will simply open in the default language each time.
8. Your rights regarding personal data
You have the following rights in relation to your personal data:
- To be told why your personal data is needed, what will happen to it, and how long it will be kept.
- Right of access: to obtain the personal data we hold about you.
- Right to rectification: to complete, correct, erase or block your personal data.
- Where you have consented to processing, to withdraw that consent and have your personal data deleted.
- Right to data portability: to request your personal data from the controller and transfer it in full to another controller.
- Right to object: to object to the processing of your data. We will comply unless there are legitimate grounds for the processing.
To exercise these rights, contact us using the details below. If you have a complaint about how we handle your data we would like to hear it, but you also have the right to complain to the supervisory authority — in Spain, the Agencia Española de Protección de Datos.
