Where the data comes from.

Schoolplot runs on your own roster, not a national average. You send an export from your MIS with a pupil reference, a postcode, month and year of birth, and the dates each pupil joined and left, but no names and no full dates of birth. You upload it yourself, and update it whenever you like. It's held under a written data processing agreement. The demographics are official public statistics for every neighbourhood in England, from the latest release of each source. Every layer on the map says where its numbers came from.

Your roster is used to draw your own school's map and to check the model behind it. It will never be sold, and no other school can see it. Only the people your school invites can sign in. It is held in London. On the map each pupil is a dot scattered about their postcode, never a pin on a home. Your school remains the data controller, and Axis Maps handles it only under the data processing agreement.
