Cookie policy
Essential cookies keep the site working. Meta's advertising cookies are set only if you accept them in the cookie banner, and never in a browser where someone has told us they are under 16. We use no analytics beacons.
What we store
| Cookie | Purpose | Lifetime |
|---|---|---|
| Authentication | Keeps you signed in and protects your account session. | Up to 30 days |
| Guest test | Identifies this browser to your guest test: keeps an in-progress test resumable, lets a later registration claim your results, records which questions you have seen so no assessment repeats one, and lets a later test reuse your age answer, if you gave one. | 90 days |
| Anti-forgery | Security token that prevents cross-site request forgery on forms. | Session |
| Notices | Carries a one-off message, such as "Your plan is ready", to the next page, then is removed. Unless you have rejected advertising measurement, it also carries a pending conversion (a new account, a sent message or a finished free test) to the one page that reports it. | Until that page |
| Cookie choice | Remembers whether you accepted or rejected advertising measurement, so the banner doesn't ask on every page. | 180 days (Safari and other WebKit browsers keep it for up to 7) |
| No-ads marker | Set if you tell us you're under 16, or sign in to an account that did. Keeps Meta's pixel and the cookie banner off in this browser, and removes Meta's cookies from it. | 730 days |
| Meta pixel (_fbp, _fbc), only if you accept | Set by Meta. Lets Meta tell which of our ads led to a visit, a finished free test, a new account or a sent message. _fbc is set when you arrive from a Facebook or Instagram link that carries Meta's click id. | 90 days |
| Meta's own cookies on facebook.com (for example fr), only if you accept | Sent by your browser with the pixel's requests to Meta. If you use Facebook or Instagram, they let Meta link the visit to that account and use it for ads. Rejecting here stops the pixel but cannot delete them; Meta's own settings can. | Set by Meta (fr: 90 days) |
Two preferences live outside cookies entirely: your light/dark theme and your read-aloud speed are kept in this browser's local storage. They stay on your device and are never sent to us.
Your choice
Advertising measurement is off until you press Accept in the cookie banner, and nothing is requested from Meta before then. Press Reject, or change your mind at any time with "Cookie settings" at the foot of our public pages: rejecting removes Meta's cookies from this site and changes nothing else. Every other cookie listed above is strictly necessary to deliver a feature you asked for, which under GDPR and comparable rules does not require prior consent.
Controlling cookies
You can clear or block cookies in your browser settings at any time. Blocking the authentication and anti-forgery cookies will prevent sign-in and form submission from working.
