Updating my review : It's now a 4 star because after deleting the app and downloading again, All my info was saved. Nothing lost. I still get the request for permission which I turned off. This app works fine and is free. Solid 4 stars on my android system. [So angry that somehow this app just went Portuguese on us and then Stopped working.]

Julia, Ao atualizar o aplicativo esse problema da tradução não ocorrerá mais. Para que exista o recurso de compartilhar o grafico MOB e enviar email, o Android exige que o usuário permita o acesso ao contato. Garantimos que não trabalhamos com nenhuma informação privada, Fazemos o possível para que algum dia merecemos que você nos dê 5 estrelas.

I get a reminder that says I have to click ok for the app to work. Not sure what that is about. I have to close the reminder every time I make an entry.
