Am I signing out of Facebook properly?

[Kitteh]

Ever since I got my iPhone, which I've had for atleast a year now, I never properly log out, I just close the app down. Will this be seen as me logging off it will the little green ball next to my name constantly stay active? I never use facebook anymore so it isn't such a big deal I would just rather make sure I'm not being seen as active 24/7. Bit of a stupid question but whatever

When other people look at it, it won't have the Green Dot. It will show a symbol of a phone and next to it will show how long it has been since you closed the app.
