Cookie policy
Last updated:
This site does not use cookies. None of our own and none from third parties, neither technical nor advertising. What we do, if you let us, is store a few values in your browser's memory to measure how the site performs. That is why we ask when you arrive: nothing is stored or sent until you answer, and if you say no the site works exactly the same.
What there isn't
- No cookies. There is not a single instruction in the site's code that writes one.
- No third-party resources. Fonts are served from our own server, not from Google Fonts. There is no CDN, no embedded maps, no YouTube or Vimeo videos, no social buttons, no chat widget, no reCAPTCHA.
- No advertising trackers. No Google Analytics, no Meta pixel, no remarketing tools. Nobody outside our team sees your visit.
- No profiling and no cross-site tracking. We do not know where you were before or where you go next, beyond the site that linked you here.
What we do store in your browser
Four keys, all ours, none of them a cookie: they live in the browser's local storage and are not sent with every request the way a cookie would be. Spanish law treats them like cookies (article 22.2 of the LSSI), which is why we ask permission; here they are one by one:
| Key | Where | How long | What for |
|---|---|---|---|
ivt_sid | sessionStorage | Until you close the tab | A random number that groups the pages of a single visit, so we can tell whether people read one page or five. It is only written if you accept. It is not tied to you: it disappears when the tab closes and the next one is different. |
ivt_attr | sessionStorage | Until you close the tab | Records where you arrived from (an ad, a campaign, another site) so we can attribute the request you send at the end. It is only written if you accept. Without it, someone who arrives from an ad and writes to us three pages later shows up as a visit with no origin. |
ivt_consent | localStorage | One year | Your answer to the notice: yes or no. It is the only thing stored without prior permission, because without it we would have to ask you on every page. It expires after a year and we ask again. |
ivt_consent_at | localStorage | One year | The date you answered, which is what lets us know when the previous answer expires. |
How we measure
- The analytics are ours and run on our own server. There is no intermediary.
- We do not store your IP address. It is turned into an irreversible code together with a random salt that changes every day, so we can count how many different people visit us today, but we cannot recognize you tomorrow or undo the calculation.
- We record page views, reading depth, button clicks, form submissions, language and whether the device is mobile. None of that identifies you.
- If your browser sends the “Do Not Track” signal, we measure nothing at all, with no action needed from you.
The full detail is in the privacy policy.
Your choice
You can change it here whenever you like, as many times as you like. It is stored in this browser on this device; if you use another one, you will need to say so there too.
From your browser
You can also clear this site's storage or block it entirely from your browser settings. Doing so removes every key above, including the one that remembers your answer: we will ask you again on your next visit.

Changes to this policy
If we ever add anything that stores data in your browser, this page will say so beforehand and in the same level of detail. If what we add requires your consent, we will ask for it: we will not assume it.
