The short version. Certmesa is hosted in the European Union. It does not track you, profile you, or sell anything about you. There is no analytics provider, no advertising network, and no third-party cookie.
Certmesa runs entirely as static HTML, CSS and JavaScript served from a server in the EU. There is no account system, no login, and no form submission of any kind. As a consequence, the site does not collect or process:
The site sets no cookies. It uses a single browser localStorage entry, certmesa-theme, to remember whether you chose the dark or light theme. This value never leaves your device. If you clear your browser storage, it disappears.
The site uses two web fonts (Inter and JetBrains Mono). Both are self-hosted from this domain under the SIL Open Font License; no request is made to fonts.googleapis.com, fonts.gstatic.com, or any other third-party CDN to fetch them.
No third-party scripts, trackers, advertising networks, or content delivery networks are used anywhere on the site.
The site runs a small server-side counter at /count.php. It accepts four events: test_start and test_complete for the lightweight quick-quiz on each cert page, and exam_start and exam_complete for the fullscreen real-exam simulator. The start events record only the certification id; the complete events record the certification id and your final score.
That is the entirety of what is recorded. The counter does not store IP addresses, user agents, referrers, browser fingerprints, country, language, time-of-day, or any other identifier that could be linked back to you. It writes to a single JSON file containing aggregate totals only, for example "test_start:ccfa = 42" or "exam_complete:ccfa = 17", never per-event rows. The aggregate is publicly visible at /stats.
The purpose of the counter is to let the site operator see which certifications people actually practice for, so that effort goes into building question banks people will use. If you would like to opt out, blocking /count.php in your browser or ad blocker prevents the events from being recorded; the site will continue to work normally.
Every question, answer option and explanation on this site is original work, written from the publicly available exam objective documents published by each certification body. Nothing is harvested from real certification exams. No exam dumps, no leaked exam pools, no sat-and-recalled questions, no reproduction of confidential exam content.
The practice-exam question banks, explanations, certification-page text and parts of the site code on Certmesa were drafted with the assistance of generative AI tools (large-language-model systems). Every output is reviewed by a human operator against the official vendor exam objectives before publication. The certification bodies named on this site (CompTIA, Cisco, AWS, Microsoft, ISC2, PMI, PeopleCert, and the others listed in the catalog) are not affiliated with, did not produce, and did not approve any of the content here.
This disclosure is provided proactively in line with the EU AI Act transparency expectations for AI-generated content (Article 50) and so that you can correctly weigh the source of what you read. If you spot an error in any question, explanation or domain summary, please report it via the contact page so it can be corrected.
The hosting provider keeps standard web server access logs (request URL, timestamp, status code, transient IP) for the technical purpose of operating the server and defending against abuse. These logs are retained for the minimum operational window and are not shared with any third party.
When you take a practice test, your individual answers are evaluated entirely in the browser. The review page is generated locally on your device. The only thing that leaves your browser is the aggregate counter event described above: your final score (an integer out of ten) without any session, identity or per-question data attached to it. The score is added to a running sum and count for that certification so an average can be displayed on the stats page; individual scores are never stored.
