Cookie Policy
Which files Atenza stores in your browser, what for, and how to refuse the ones that are not essential.

What a cookie is
A cookie is a small file a site asks your browser to store and hand back on the next visit. It is what keeps you signed in as you move between pages, instead of typing your password on every click.
The ones you cannot refuse
Three files are a condition for the system to work at all, so they are not subject to consent: without them there is no sign-in, and without sign-in there is no service to deliver.
- Session — keeps you authenticated. It is `HttpOnly`, `Secure` and `SameSite=Strict`: not readable by JavaScript and never sent to another site.
- Theme and language preference — remembers the choice you made in the interface.
- Cross-site request protection — stops another site from issuing commands on your behalf.
Visit measurement
The public page records which country and city the visit came from, which site you arrived from and which campaign brought you. Origin is read from the request headers and the page address, not from a third-party tracker: there is no ad-network pixel and no advertising profile built about you.
Your IP address is not stored in the clear on the visit record. What remains is the geolocation result — coarse enough to inform a product decision, and far too coarse to identify a person.
How to refuse
Every browser lets you block or delete cookies in its privacy settings. Blocking the essential ones prevents sign-in — that is not a degradation, it is a closed door. Blocking visit measurement changes nothing in what you see.
