Cookie Policy
Cookies are small files a website stores on your device. We keep ours to a minimum: the ones we can't do without, and (only if you agree) analytics cookies that would help us improve the site, and marketing cookies that let us measure our Meta (Facebook/Instagram) ads — used only on our public marketing pages, never in the parent, tutor or admin portals. This page lists every one and lets you change your mind whenever you like.
What cookies are
A cookie is a small piece of text a website asks your browser to store. Some are strictly necessary (without them you couldn't log in or stay logged in) and the law lets us set those without asking. The other kinds we use are analytics and marketing, and both need your consent first and stay switched off until you give it. Marketing cookies (our Meta Pixel) are only ever set on our public marketing pages — the homepage, subjects, contact, our per-subject pages (such as maths or science) and our ad landing pages — never on the parent, tutor or admin portals. We treat other on-device storage (such as remembering your light/dark theme) the same way.
The categories we use
Essential

Analytics

Marketing
Off by defaultLets Meta (Facebook/Instagram) measure how well our ads are working, on our public marketing pages only — such as the home page, pricing, how it works, subjects, workshops, free consultations and our ad landing pages. Never set on the parent, tutor or admin portals. Off unless you turn them on.
