Restore to Factory Settings:

If you are so concerned, then restore your iPad to factory settings. Go here: What to do Before you Sell, Give Away, or Trade in your iPhone, iPad, or iPod touch - Apple Support

Backing Up Items:

Note that all downloads would be lost. So, make a note of Apps that were downloaded. Also, enable items in iCloud, so that all is backed up. As an example, here is how to backup Contacts...

I. Enable Contacts in iCloud Settings:

Is Contacts enabled in iCloud Settings? If not, then enable it, and see if it pops up. If so, then it is gone amongst all devices associated to your Apple ID. So, to enable it:

Enable Contacts in iCloud:

1. Go to: Settings
2. Tap: your name (top item)
3. Tap: iCloud
4. Tap: Contacts (so that it is green)

and...

B. Enable on a Mac:
