Greetings Jaboli,
Great question. You can adjust your iCloud settings to select which apps you want to sync, on your iPads. Here's how:
Change which apps sync and store data with iCloud
"In your iCloud settings, you can choose which apps on your device sync and store data with iCloud. Learn how to change your iCloud settings, or turn off iCloud completely.
When you turn on iCloud for an app, its information is safely stored in iCloud and automatically kept in sync across your devices. When you turn it off, the app no longer connects with iCloud, so your data exists only on your device.
You can choose which apps on your device you'd like to use iCloud, or turn off iCloud completely.
Choose which apps to use with iCloud
After you sign in to iCloud on your devices, learn how to find your iCloud settings on your iPhone, iPad, Mac, or PC.
On your iPhone or iPad
- Go to Settings > your name.
- Tap iCloud.
- Tap to choose which apps you want to use iCloud."

Thanks for posting in Apple Support Communities.
Have a wonderful day!
