As a Gynzy administrator you can revoke access to Gynzy for a specific teacher on your school's account. This teacher will still keep his/her user-account but will be unable to use Gynzy on the school's license. You can do this by:
1. Logging into the School Administration Site http://schools.gynzy.com;
2. Selecting the specific user;
3. Clicking on the 'Undo approval' button at the bottom of the page.
