SUMTerms of service
The terms for using Sumburst: accounts, subscriptions, cancellation, acceptable use and refunds.
Accounts
An account is for one family or one classroom. Keep the password to yourself. If a child uses the account, a parent or guardian is responsible for it.
Subscriptions and cancelling
Paid plans renew monthly or yearly until cancelled. Cancel any time from your account; access continues to the end of the period already paid for. There is a free plan, so nobody has to pay to try it.
Acceptable use
Do not try to break, copy or resell the service, and do not use it to harass anyone. We can suspend an account that does.
What we promise
We do our best to keep the site up and the games working, but we can't promise it'll never go down. And nothing here is a promise about how a child will do at school.
