If you have set up an automatic payment for the Teacher Plus account and want to postpone or cancel the automatic payment: Select Account (under you name) then choose** Billing*. You will see *"Cancel my subscription"**.
You can select this for the summer months you are not going to use GradeCam. If you choose to start using the full version the next school year, select "Upgrade to the Teacher Plus version". No data will be lost. The account will only downgrade to the free version during the unpaid months.
