Meo is like a social network, but it isn't social, and there's no network. So it's just a notes app, that looks like a social network. All data is store locally in your device, private by default.
The app is still under development but we are hoping to have a public release soon!
If you are willing to join the beta testing on both iOS and Android send a DM on twitter to @_weslleyaraujo or @pmarquees
