Samsung currently has an unremovable spyware app on North American phones that pastes (records) everything copied to the clipboard by any app. It is the Samsung Keyboard app. It cannot be removed. It doesn't matter if you're using any other keyboard app. Samsung Keyboard pastes (records) everything that gets copied to the clipboard by any app. The Samsung Keyboard app cannot even be disabled from Android.
As an aside, I recall getting a lot more ads when I used Samsung Keyboard.
