In Notezilla , by default all sticky notes are synced with other devices.
If you don't want those sticky notes on Android device and other devices (including other Windows PCs), then you can move those notes to offline memoboards (new in Notezilla 9).
You will find a memoboard called "Offline" in Notes Browser. You can move all those notes to this memoboard. Or you can create another Offline memoboard too with the name you want.
