Cookies Statement

What are cookies and what are they used for?

Cookies are very small text files that are stored on your computer through your web browser when you visit websites. These small files contain some user-specific information that can be used to improve your experience on our website, as well as allow us to perform analyses of purchase behavior on our website.

You can disable any cookies already stored on your computer, but these may stop our website from functioning properly.

You can withdraw your consent on the use of cookies on our website at any time by clearing this site's data in your browser. This website stores nothing that requires your consent: what it keeps is the language you chose, the fact that you dismissed the cookie notice, and — while you are logged in — your login session. While you sign in with Google, confirm your e-mail address or reset your password, it keeps a one-time security code. After you register, it also keeps the course you wanted to book, for at most 24 hours, while you confirm your e-mail address. On the sign-up, sign-in and password-reset pages, the security check from Cloudflare keeps one value of its own; see the list below.

What types of cookies are we using and why are we using them?

We use functional cookies only.

Functional cookies enable us to improve your experience on the website and remember your choices. For example, the site remembers the language you picked, and it keeps you logged in as you move between your courses. This storage is always active except if you expressively ask your browser to not accept cookies.

Tracking cookies enable a website to track your actions in order to learn behaviors. This website uses none. There is no Google Analytics on it and no Facebook Pixel, and no advertising service either, so nothing about your visit is sent anywhere for targeting or ad performance. We do measure which pages are visited and how fast they load, using two tools from our hosting provider Vercel. These tools set no cookie and store nothing in your browser. You can read what they send in our Privacy Statement.

Details about the cookies on our website

The cookies and stored values on our website:

sf-site-language — Remember what language you have selected to tailor the website to your need (functional). Kept in your browser’s local storage until you clear this site’s data.

sb-…-auth-token — Remember that you are logged in (functional). A cookie, kept for 400 days from your last visit while logged in, and deleted when you log out. A long session can be split into sb-…-auth-token.0, .1 and so on.

sf-ziel — Remember which course you wanted to book while you confirm your e-mail address after registering, for at most 24 hours (functional). A cookie, sent only to the page that confirms your address.

sb-…-auth-token-code-verifier, sb-…-auth-token-flows-code-verifier and sb-…-auth-token-flow-…-code-verifier — A one-time security code while you sign in with Google, confirm your e-mail address or reset your password (functional). Cookies, kept for 400 days unless you clear this site’s data.

sf-site-cookieconsent — Remember that you dismissed this cookie notice, so it is not shown again (functional). Kept in your browser’s local storage until you clear this site’s data.

cf.turnstile.u — Stored by Cloudflare’s security check on the sign-up, sign-in and password-reset pages (security, strictly necessary). Kept in your browser’s local storage under Cloudflare’s own address, challenges.cloudflare.com, not as a cookie, until you clear the stored website data. We measured it ourselves; Cloudflare does not document it.

No cookie on this website tracks your behavior, your device, your browser, your network provider, the HTTP headers your browser sends, or the buttons you click.

The visit and loading-speed statistics from Vercel use no cookie and store nothing in your browser, so they do not appear in this list. The Web Analytics script looks for one stored value, __va_attribution, which this website never stores.

When you pay, you are on Mollie’s page, and when you sign in with Google, on Google’s. Those pages set their own cookies under their own statements; this list covers our website, including the one value that Cloudflare’s security check keeps on our sign-up, sign-in and password-reset pages.
