Cookies

Last updated: 16 August 2026.

Scope

This policy explains the cookies and similar local technologies used on fiscalrail.com and the FiscalRail dashboard. Cookies are small files stored by a browser. Similar technologies can store or retrieve identifiers for the same kinds of purposes.

Current position

FiscalRail does not currently use advertising cookies or third-party web analytics on its public marketing pages. The dashboard uses strictly necessary first-party cookies for authentication, session continuity, security and interface operation. The marketing language switch uses page links and does not currently require a tracking cookie.

Because these technologies are necessary to provide a service you request or to secure it, they do not require consent under the current Spanish cookie rules. If we add non-essential analytics, advertising or similar technologies, we will update this policy and request consent before using them where required.

Browser controls

You can inspect, block or delete cookies using your browser settings. Blocking strictly necessary cookies may prevent login or other dashboard functions. Browser controls do not necessarily clear server-side account or security records.
