Public App and data privacy

[teambelair]

Hi Appsheet fanatics,

When creating a public app, it is required to turn on the option: “Yes, the data in this app is public”.
I am building an app for students to workout during the quarantine and need to have the user/parent signs a disclaimer/waiver when opening the app. To do so, I have a form with the user agreement, first and last name and signature. The data collected is then obviously not accessible to any users.
I read other topics saying that the data can be indexed by Google and thus accessible by others. Is that true? Otherwise I can have a link to a Google form disclaimer with the same field but I would prefer to have this form within the app.

Thanks!
