QuickMemo+ ?

[Murf1]

Anyone know where the QuickMemo+ stores the memos you type in when you 'sync'? It's in the cloud somewhere. I had memos (like sweeper bag type etc.) typed in the "Memo" app that came on my LG Volt phone - and on Virgin Mobile as my carrier. To my surprise, after I hand typed them all back in on my Stylo, when I did the sync on the Stylo (on Boost Mobile), it pulled them in. Was thinking about using Google Keep app, but this seems to work. But if I ever got a non-LG phone, the sync would no longer work, right? I am presuming the "QuickMemo" and "Memo" apps are an LG thing only.

So where in the cloud are these memos stored?

thanks
