What we use

We use cookies, local storage and similar technologies in your browser. Some are required for the service to work; others measure advertising performance.

Strictly necessary

• Session and login tokens that keep you signed in.
• Local storage that saves your assessment progress on your own device so you do not lose your answers.
• Security tokens used during payment and 3-D Secure verification.

Preferences

• A language cookie that remembers the language you selected.

Analytics and advertising

These are set only after you accept advertising cookies.

• _fbp (Meta) — browser identifier used to attribute sign-ups and purchases to ads. Duration: up to 2 years (Meta default).
• _fbc (Meta) — stores the click identifier from a Meta ad. Duration: up to 90 days.
• _scid / _schn / sc_at (Snapchat) — identifiers used to attribute conversions to Snapchat campaigns. Duration: up to 13 months.

How to control cookies

Advertising cookies (Meta, Snapchat) are only loaded if you accept them in the cookie banner. You can change or withdraw that choice at any time via the “Cookie settings” link in the footer of every page.

You can delete or block cookies in your browser settings at any time. Blocking strictly necessary cookies will prevent login, checkout and the assessment from working. You can also opt out of ad personalisation in your Meta and Snapchat account settings.
