Your school may only be using Pobble with a few classes, a Year Group or a Key Stage. In this case you will not require data for the entire school to be included.
Head to your Wonde portal, which will be set up for you by Wonde on your initial call.
Select The ‘Access Control’ tab, which is available via Dashboard/Advanced Actions menu
Check the third option -
“Allow access to certain users and exclude access to all others”
You can search for and select which Registration/Year Groups to include/exclude by clicking “Filters” and scrolling down.
