Ion_auth remember me IE 11

I've come accross a very strange behaviour of IE 11 together with the fabulous Ion_auth library.
On my login pages (on 4 different websites) I have a "Remember me" checkbox. I leave it unchecked. On localhost, if I close the browser - IE 11 - without logging out, it forces me to login again at my next visit. That's how it should be.
On the live versions (hosted) however, IE 11 will log me in automatically, even when "Remember me" was unchecked.
I tried the same in Chrome. That browser doesn't remember me unwantedly.
Anyone who can explain this?
