Help saving changes to cloud

I’m new at this and trying to make a caught/uncaught toggle checklist but I want the users progress to save for when they log back in. I’ve gotten as far as making a Firebase database and I just want to rewrite this so it begins saving progress

The variables you’re using are “app” variables which only store values while an app is running. If you want to store values after an app is closed, you will need to use a “stored” variable or a cloud-based storage such as Google Sheets, Airtable, or Firebase.

Firebase is much more difficult to use than the other options. But it’s very flexible. Start here: Connect a Firebase Realtime Database | Thunkable Docs
