1. Summary, in one line
This site does not use cookies — neither its own nor third-party ones — and it does not track you. There is no advertising, no analytics and no profiling.
2. What we actually use
So that the language switch remembers your choice, the site stores a technical item in your browser's local storage (localStorage), not a cookie:
| Name | Purpose | Duration |
|---|---|---|
sfc-lang | To remember whether you prefer to view the site in Spanish or in English. | Until you clear your browser data. |
That item is not sent to any server, it does not identify anyone and it is not shared with third parties. It does not require consent because it is strictly technical and necessary for the function you activate.
3. What we do NOT use
- Web analytics cookies (we do not measure visits with third-party tools).
- Advertising or profiling cookies.
- Fonts, maps, videos or widgets loaded from external servers.
The site loads no third-party fonts or scripts: everything you see is served from this same server. That is why you will not see the usual cookie banner: there is no need to ask permission for something that is not used.
4. How to delete that technical item
If you want to remove it, you can clear the site data from your browser:
- Chrome / Edge: Settings → Privacy and security → Clear browsing data → “Cookies and other site data”.
- Firefox: Settings → Privacy & Security → Cookies and Site Data → Manage Data.
- Safari (iPhone/Mac): Settings → Safari → Clear History and Website Data.
- You can also browse in private mode: the language will not be remembered between visits.
5. If this changes
If an analytics tool or any cookie that is not strictly technical is added in the future, this page will be updated and, where the law requires it, your prior consent will be requested through a notice with the option to accept, reject and configure.
6. Applicable regulations
This policy complies with Article 22.2 of the LSSI-CE and with the Spanish Data Protection Agency's Guide on the use of cookies. If you have any questions, see the privacy policy or write to us.
