What cookies are
Cookies are small text files that websites store on the user's device (computer, phone or tablet) to remember information about the visit: for example, to keep a session open or to keep the preferences chosen. Alongside cookies there are similar technologies, such as the browser's local storage (localStorage), which perform equivalent functions and are subject to the same regulations.
This policy has been drawn up in accordance with article 22.2 of Spanish Law 34/2002, of 11 July, on information society services and electronic commerce (LSSI-CE), and the guidelines of the Spanish Data Protection Agency on the use of cookies.
Types of cookies
Depending on who manages them, cookies can be first-party (sent from the website's own domain) or third-party (sent from a domain managed by another entity). Depending on their purpose, they include, among others:
- Technical: essential for the website to work (keeping a session open, ensuring security, remembering the content of a form).
- Preference or personalisation: they remember options chosen by the user, such as the language or the visual theme.
- Analytics or measurement: they make it possible to count the number of visitors and analyse how they use the site.
- Behavioural advertising: they store information about browsing habits in order to show personalised advertising.
Technical cookies and personalisation cookies expressly chosen by the user are exempt from consent; analytics and advertising cookies require prior authorisation.
Cookies used by this website
artheon.es is an informational website and makes minimal use of these technologies. No cookies are installed on your device during ordinary browsing. The only items that may be stored are the following, all first-party and exempt from consent:
| Name | Type | Purpose | Duration |
|---|---|---|---|
| tema | Preference (local storage) | Remembers the visual theme, light or dark, that you choose with the button in the header. It is only created if you press that button. | Until you delete it from your browser |
| idioma-sugerido | Preference (local storage) | Remembers that you have closed the notice suggesting the website in your language, so that it is not shown again. It is only created if you close or follow that notice. | Until you delete it from your browser |
| better-auth.session_token | Technical (session) | Keeps the session open for authorised people in the gallery's management panel. It is only created when signing in to that panel. | 7 days |
| better-auth.session_data | Technical (session) | Temporarily stores the data for that session so that it does not have to be looked up on every page. Management panel only. | 5 minutes |
The management panel cookies only affect the people who sign in to it; visitors to the website never receive them. In the production environment they carry the __Secure- prefix and are only transmitted over encrypted connections.
Third-party cookies and external services
This website does not use analytics tools, advertising pixels, social media buttons or embedded videos that install third-party cookies. Fonts are served from our own servers and images from our own storage, so your browsing is not shared with any external provider.
Links to third-party sites that may appear on the website are governed by those sites' cookie policies, which we recommend you consult.
Consent
Since the website only uses technical cookies and personalisation preferences that you expressly choose, it is not necessary to ask for your consent or to display a cookie notice. If in the future we add analytics cookies or others that require it, we will let you know through a settings panel that will allow you to accept or reject them before they are installed, and we will update this policy.
How to manage or delete cookies
You can allow, block or delete the cookies and data stored by this website from your browser settings. Please note that if you delete the “tema” item, the site will be shown again with your system's theme; that if you delete “idioma-sugerido”, you may see the language notice again; and that without the session cookies it is not possible to use the management panel.
Updates to this policy
This policy may be modified when the technologies used on the website or the applicable regulations change. The version in force will always be the one published here, indicating the date it was last updated (19 October 2026). For more information on how your personal data is processed, please see our privacy policy.
