Privacy & safeguarding
Only the information needed to run the service is collected. Pupil email addresses are never required — schools may use initials, aliases or school-generated IDs.
Passwords are stored using secure hashing, access is role based, and each school's data is kept entirely separate. Pupils can only ever see their own results.
There is no advertising and no third-party tracking on pupil pages. Pupils are logged out automatically after a period of inactivity. Important account changes are recorded in an audit log available to teachers, who can also export or delete school data.
