How much costs Klapp?
The price per user (student and teacher) per year is equivalent to the price of one Big Mac in your country.
Klapp is free for parents.
We only charge for users who are assigned to at least one active class. A class is active when at least 90% of the students are connected with parents (guarantee of success!).
And if Klapp should not inspire you, then simply let us know. Your account will be closed and no invoice will be issued.
