Install an editable copy: this creates your own project, not a shared reference.
This app is free: installing it costs nothing. Install creates an independent editable copy in your account with its own project id, openable in the builder. No payment, no subscription, and no platform fee on a free install. Individual educators do not need a subscription to use K12.io or to install a free app.
