Cookie policy
Version of 29 September 2026
This page is a translation. The Spanish original at holacasilla.com/cookies/ is the binding text; if the two differ, the Spanish text prevails.
A cookie is a small file that the browser stores when you visit a site and returns on later visits. This page says which ones Casilla sets, what for and for how long.
This site uses no cookies
holacasilla.com is a static site. It sets no cookie, loads no analytics or advertising, and embeds no third-party content that might set any.
The application uses four, all technical
app.holacasilla.com uses only cookies necessary to provide the service you ask for when you sign in. They are exempt from consent under article 22.2 of Ley 34/2002, on information society services, and that is why there is no banner: there is nothing to accept or reject.
| casilla_session | Your signed session. Thirty days; eight hours for administration. Without it there is no way to know who you are. |
|---|---|
| casilla_nif | The book you have chosen when you have access to several. Lasts the session. |
| casilla_locale | The interface language. Kept until you change it. |
| casilla_oidc | Protection of the Google sign-in against forgery (state, nonce, PKCE). Ten minutes. |
All of them are first-party (they are set by app.holacasilla.com and read only by app.holacasilla.com), carry the HttpOnly, Secure and SameSite=Lax flags, and none identifies anyone outside the application.
What there is not
No analytics cookies, no advertising, no social media, no third-party ones. If one day a non-strictly-necessary cookie were needed, this page would change first, and a mechanism to accept or reject it would appear before it was set.
How to delete them
Leaving the application deletes casilla_session and casilla_nif. The others are deleted from your browser's settings. Without cookies the application cannot work: every visit would ask you to sign in again.
