For adults: parents, carers, teachers and anyone learning on their own.
Cookies
The short version
- We use two cookies, both for what you asked us to do: one keeps you signed in, and one remembers your school if you tick the box.
- No tracking cookies, no advertising cookies, and nothing from anyone else.
- That is why there is no cookie banner: the law does not ask for one when every cookie is needed for the service to work.
What we put on your device
| Name | What it does | How long it lasts |
|---|---|---|
| pmb_session | Keeps you signed in. Set only when you sign in, and only for the address you signed in at | Until you sign out, or until you have been away long enough that we sign you out |
| pmb_school | Remembers your school’s address. Set only if you tick “Remember this school on this device” | A year, or until you untick the box |
| pmb-paper-flags | Remembers which questions you flagged in a timed paper, so a reload does not lose them. Kept in the browser, never sent to us | Until you close the tab |
Help videos
Our help videos are played from our own storage, by your browser’s own player. They set no cookies and never play by themselves.
