Cookie Policy
In short
- Essential cookies keep you signed in and the Service working. They are always on.
- Preference storage remembers things like your help chat and your theme. It is off unless you allow it.
- We use no advertising, analytics or tracking cookies, and none from third parties.
What we store on your device
| Name | Kind | What it does | How long |
|---|---|---|---|
| sb-…-auth-token | Essential | Keeps a guardian or staff member signed in. | Until you sign out or the session ends |
| cohort_student | Essential | Keeps a student signed in to their lessons. | Until they sign out |
| cohort_cookies | Essential | Remembers your cookie choice. | 6 months |
| cohort_cur | Essential | Set only if you switch between naira and US dollars: shows prices in the currency you chose. Without it, the currency is worked out in your browser from its time zone and language, and nothing about it is sent to us. | 1 year |
| cohort-splash | Essential | Shows the opening animation once per visit, not on every page. | Until the tab closes |
| Student app storage | Essential | In the student app only: keeps the current lesson, the read-aloud setting, and whether the install prompt was dismissed, so lessons work smoothly. Covered by the guardian’s consent at registration. | Until cleared |
| cohort:chat-key | Essential | Set when you use the help chat: links this browser to your chat, so our team’s replies reach you and it carries on across pages. | Until the tab closes, or 24 hours if you allow preferences |
| cohort:family-chat:v1 | Preference | Remembers the help chat in the family app. | Until the tab closes |
| cohort:chat:open | Preference | Reopens the help chat after a refresh if it was open. | Until the tab closes |
| cohort-family-theme | Preference | Remembers day or night theme in the family app. | Until cleared |
Your choice
When you first visit, we ask whether to allow preference storage. You can change your choice at any time with “Cookie settings” at the foot of every page. Declining never stops the Service working; it only means we forget your preferences.
You can also clear or block cookies in your browser settings. Blocking essential cookies will stop sign-in from working.
