Cookie Policy
Last updated: 24 August 2026
The short version
Until you accept, this site stores no analytics or advertising cookies at all. The Google Analytics and Google AdSense scripts do load, but they start with consent denied through Google’s Consent Mode v2, which is applied before those scripts can run. Without your permission they measure in aggregate and do not identify you.
What actually gets stored
Much of what this site remembers is not cookies at all but browser local storage: it stays on your machine and is not sent to the server with every request. This is the complete list.
| Name | Type | What it is for |
|---|---|---|
| f1-consent-v1 | Local, first party | Stores your cookie decision so you are not asked again. Necessary: without it there is no way to honour your choice. |
| f1-theme | Local, first party | Whether you prefer the light or dark theme. |
| f1-lang | Local, first party | The language you picked, Spanish or English. |
| f1-settings | Local, first party | Interface preferences. |
| f1sim-game | Local, first party | The state of any game you have in progress, so it survives a reload. |
| whatif_saved | Local, first party | Any scenarios you saved in the What If mode. |
| next-auth.* | Cookie, first party | Only if you sign in: keeps your session open. Strictly necessary and cannot be switched off while you are logged in. |
| _ga, _ga_SCERE7ZJD0 | Cookie, Google | Google Analytics 4. Measures visits statistically. Only written if you accept analytics. |
| Google AdSense cookies | Cookie, Google | Advertising. Only written if you accept advertising. With consent denied, any ads served are non-personalised. |
The three categories
- Necessary. They make the site work: remembering your cookie decision, your language, your theme and your game. They cannot be switched off, because without them there is no usable site, and they are not used to profile you.
- Analytics. Google Analytics 4, to know which pages get read and which do not. It is what tells me whether an article was worth writing.
- Advertising. Google AdSense. It is what keeps the site free. If you decline, you can still use every single part of it.
Changing your mind
Whenever you like, no explanation needed. This button reopens the panel:
You can also clear cookies and local storage from your browser settings. If you do, the site will forget your language, your theme and any game in progress, and will ask you about cookies again.
Third parties
The only third parties that can write cookies here are Google Analytics y Google AdSense, and only with your permission. What Google does with that data is governed by its own terms, which you can read in how Google uses information from sites that use its services. There are no embedded social networks, no tracking pixels from other platforms, and no advertising from any other network.
