Cookie policy
Last updated: 17 August 2026.
This page lists exactly which cookies this site uses. It is a list of what actually exists, not a generic text.
What they are
Small files a site stores in your browser to remember something between pages or between visits. Some are needed for the site to work; others let us understand what gets read and measure our campaigns.
How we ask
On your first visit a notice appears with two options, Accept and Essential only, side by side and with the same weight. Until you choose, nothing for measurement or marketing is loaded.
Your choice is kept for a year. To change it, clear this site's cookies in your browser and the notice comes back.
Essential cookies
These always load, because without them the site does not do what it promises. They do not identify anyone and do not follow you across other sites.
| Cookie | What it does | Lifetime |
|---|---|---|
NEXT_LOCALE | Remembers the language you chose, so you do not land back in English every visit | 1 year |
nilg_consent | Remembers your decision about this policy. Without it, the notice would reappear every time | 1 year |
Measurement and marketing cookies
These only load after you accept. If you choose "Essential only", none of them is written and the services themselves are never loaded.
| Cookie | Set by | What it does | Lifetime |
|---|---|---|---|
nilg_attr | NILG.AI | Records where your first visit came from (campaign, search engine, referring site), so we know what works | 90 days |
_ga, _ga_* | Google Analytics | Counts visits and pages read, with the IP address anonymised | 2 years |
_fbp, _fbc | Meta | Measures our Facebook and Instagram campaigns | 90 days |
| Apollo cookies | Apollo.io | Identifies the company behind the network a visit comes from, so we know what kind of companies visit us | Up to 1 year |
Messages that appear over the site
Now and then we show a message over the site, for instance announcing an event or offering a resource. So that we do not repeat it to someone who has already seen it, we keep four keys in your browser's storage. They are not cookies, in that they are never sent with requests to the server, but they do sit on your device:
| Key | What it does | Where it sits |
|---|---|---|
nilg_visitor | A random number, generated in your browser, with no link to who you are | Until you clear it |
nilg_popup_seen | Which messages we have already shown you, so they do not come back | Until you clear it |
nilg_popup_session | Whether one has already appeared this visit. We never show more than one | Until you close the tab |
nilg_popup_ab | Which version of a message you were given, so it does not change between visits | Until you clear it |
These four are always written, because they are what stops the message repeating, and none of it leaves your device. Measuring whether the message was seen or clicked is a different matter: that only happens after you accept. If you choose "Essential only", the message still appears and still remembers that it appeared, and we do not get to know whether you read it.
We also store the key nilg.consent.v1 in your browser's local storage (not a cookie, but it sits on your device) holding the same decision as the nilg_consent cookie.
Third-party content inside the site
Some pages embed content from elsewhere, for example videos. Those services may set their own cookies when the content loads, and they are governed by their own policies.
How to turn them off
In the notice, by choosing "Essential only". Or in your browser settings, where you can block or delete cookies from any site:
- Chrome: Settings, Privacy and security, Cookies
- Safari: Preferences, Privacy
- Firefox: Settings, Privacy and security
- Edge: Settings, Cookies and site permissions
Blocking the essential ones may stop the site from remembering your chosen language.
