For adults: parents, carers, teachers and anyone learning on their own.
Who helps us
The short version
- These companies run parts of Edlumo for us. The law calls them sub-processors.
- Each one has a written contract with us, follows our instructions, and cannot use the data for itself.
- None of them trains AI on anyone’s data.
- We tell schools at least 30 days before we add or change one.
