Two server records, no cookies
No cookie is set on these pages, and no advertising, analytics or social script is loaded. Fonts and the quiz script are served from the site itself. Two kinds of event are recorded on the server, and this page lists exactly what each record holds.
Reading pages and answering questions
There is no sign-in and nothing to fill in. The practice quizzes run entirely in your browser: the answer you pick, the explanation you open and your score stay in the tab and vanish when it closes. Moving from one page of the site to another is not recorded.
Arriving from somewhere else
When a page is requested with a link from another website, with a campaign tag in the address, or by an AI assistant or AI search service fetching it (such as ChatGPT, Perplexity or Claude), the server writes one record with:
- the page address on this site;
- the address of the page that linked here, plus utm campaign tags if present;
- the IP address and the network that owns it (AS number and its operator's name), with the country, region and city looked up from it;
- the user-agent text your browser sends.
No record is written for direct visits, for clicks between pages of this site, or for search-engine and AI training crawlers. The record exists so we can see which search engines, assistants and sites send readers to which pages.
Tapping a study-app button
App buttons on exam pages lead through go.critical-care-nurse-certification-hub.com, which forwards you to the store listing for your device. That hop records the exam, the button or device type that chose the store, the page you came from, the IP address with its network and location (including time zone and which Cloudflare location handled it), the user-agent text, any campaign tags in the link, and the time. The outgoing store link names this domain as its campaign source, letting the stores' reports attribute an install to it; what happens after that is governed by Apple's or Google's privacy terms.
Why your browser shares the page address
Every HTML page here carries the Referrer-Policy value no-referrer-when-downgrade, for every visitor. It lets the app-button hop above see which page a tap came from. It does not add cookies or scripts, and the full address is never sent from this secure site to a plain-HTTP one.
Who serves the pages
The site and the app-button hop run on Cloudflare, which processes requests to deliver them. The two records above are sent from Cloudflare to our own reporting server.
