Who is responsible
The publisher of Cert Espresso is the data controller. Contact: contact@certespresso.com. See the legal notice.
What stays in your browser
To make the site work without an account, your browser stores on your device:
- your progress for each certification: completed lessons, answers, review dates, recent sessions and planner notes (local storage);
- the last course you opened, so the home page can take you back to it (local storage);
- your choice about visit counting and, for the current tab, the logo animation setting;
- offline copies of the pages and question banks you opened (cache storage, through a service worker).
This information is never sent to us. It is needed for features you ask for, so it does not require a consent banner. You can export or delete your progress, and remove the offline copies, from the “My learning” page of each course, or by clearing this site’s data in your browser.
Counting visits
To understand which courses are useful, our own server counts visits in daily totals: the page category and certification, a broad origin (YouTube, search engine, other site or direct), a device category (phone, tablet or computer) and a few learning actions (practice started or completed, lesson opened, video played, YouTube link followed).
These totals contain no cookie, no identifier, no IP address and no fingerprint; they cannot be linked to you or followed from one visit to the next, and they are not shared with anyone. They are kept for 90 days. Legal basis: our legitimate interest in measuring the audience of our own site (article 6(1)(f) GDPR), under the consent exemption that the French authority (CNIL) grants to strictly limited audience measurement.
Visits are not counted when your browser sends a “Do Not Track” or “Global Privacy Control” signal. You can also switch counting off for this browser:
Visit counting needs JavaScript; without it, nothing is counted.
Technical logs
Like any web server, our hosting provider (alwaysdata, France) records technical logs of requests, which include the IP address, the date, the address requested and the browser identifier. They are used only to operate and secure the service and are kept for a limited period by the host. To limit abuse, the server also counts requests per IP address in memory for about two minutes; this counter is never written to disk.
YouTube videos
Videos are hosted by YouTube (Google). Nothing is loaded from YouTube until you press play or follow a YouTube link. The embedded player then loads from YouTube’s privacy-enhanced domain (youtube-nocookie.com), and Google receives your IP address and may process data under its own privacy policy .
When you write to us
Issue reports are prepared in your browser and nothing is sent automatically. If you e-mail us, we use your address only to answer you and delete the exchange within one year.
Your rights
Under the GDPR you can ask to access, correct or erase your personal data, restrict or object to its processing, and lodge a complaint with a supervisory authority, in France the CNIL . Because we hold no data that identifies visitors, we usually cannot find anything about you; your study data is in your own browser and under your control. For any question: contact@certespresso.com.
