Your students are not our data.
Aula runs no servers of its own. What you write about your students stays encrypted on your device and, if you turn it on, in your personal iCloud.
Aula never accesses, under any circumstance, the student, family, grade or observation data you enter in the app.
The school remains the data controller and you act as authorised personnel. Aula is the tool, not a middleman holding your data.
