Cookie policy
Last updated: 18 September 2026
What a cookie is
A cookie is a small file that a website stores in your browser to remember information between visits. It is not the only way to do so: a site can also store data in the browser's localStorage, a separate storage area that is only accessible from this domain and that, unlike a cookie proper, is not automatically sent to the server with every request.
What this site stores today
Before you respond to the cookie notice, this site stores nothing except that pending decision: there is no analytics or advertising cookie, and no entry in localStorage.
Your response to the notice is stored in cookie-consent, in localStorage, not in a cookie. The notice offers three responses, and what is loaded depends on which one you choose. If you accept analytics, the site loads the Google Tag Manager container, which in turn loads Google Analytics 4 and sets the _ga cookies. If you also accept advertising, it loads the OpenAI measurement SDK (Conversions API), which sets the __oppref cookie and uses sessionStorage so as not to count the same visit twice. If you decline, neither of them is loaded:
| Name | Type | Purpose | Duration |
|---|---|---|---|
| cookie-consent | localStorage (not a cookie) | Remembers whether you accepted or declined the measurements, so that we do not ask you again. | Until you delete it or withdraw your decision. |
| _ga | First-party cookie (Google Analytics), analytics | Distinguishes visitors in order to count how many people visit the site and where they come from. It is set by Google Analytics 4, loaded from the Google Tag Manager container (googletagmanager.com), and only if you accept analytics. | 2 years from the last visit. Deleted as soon as you withdraw your consent. |
_ga_ followed by the property identifier | First-party cookie (Google Analytics), analytics | Keeps the state of the analytics session, so that a single visit is not counted as two. It is set by Google Analytics 4 under the same conditions as the previous one. | 2 years from the last visit. Deleted as soon as you withdraw your consent. |
| __oppref | Third-party cookie (OpenAI), advertising | Identifies the OpenAI advertising click that brought you to the site, so that OpenAI can attribute the conversion to it. It is set by the OpenAI SDK loaded from bzrcdn.openai.com, not by this site, and only if you accept advertising. | Defined by the OpenAI SDK; this site does not control its duration. Deleted as soon as you withdraw your consent. |
| oaiq-goal-sent | sessionStorage (not a cookie), first party | Records that the conversion goal has already been sent in this session, so that two clicks from the same visitor do not count as two conversions. | For as long as the browser session lasts; it is deleted automatically when you close the tab. |
How to withdraw your decision
You can change your decision at any time, as easily as you gave it: press the button below and, on your next interaction with the site, you will see the consent notice again.
As a secondary note, you can also delete the cookie-consent entry from localStorage manually, from your browser.
How to delete it from your browser
- Chrome: Settings → Privacy and security → Delete browsing data → Cookies and other site data.
- Firefox: Settings → Privacy & Security → Cookies and Site Data → Manage Data.
- Safari: Settings → Privacy → Manage Website Data.
- Edge: Settings → Privacy, search, and services → Clear browsing data.
You can also open your browser's developer tools (F12), go to the storage tab (Application/Storage) and delete the cookie-consent entry directly.
