Question: if I do not log out of the remote app, does it maintain a connection to my server at home and eat bandwidth? Or does it close the connection on its own after a period of inactivity?
On your android device, if you're using the web browser or cryptoglance app, when the app is not active on your screen it should pause any network connectivity... You can ensure it will not use data in the background by navigating to Android Settings (general phone settings) -> Data Usage -> CryptoGlance -> Restrict Background Data (enable this).
Is there a way to make the remote app "remember" me? My password is super long and random, not fun to have to input every time. Pending the answer to above, I could just never log out, but not sure. If the connection is maintained, I will log out each time. If the connection is not kept live, then there's really no need for me to log out of the app, and thus no need for it to remember me.
To get the remote app to connect using httpS I'm guessing I have to configure some stuff on my home computer/firewall, have any handy links where I can read up on this? I know nothing about SSL, but I'm a fast learner.
Not too sure about an easy https implementation. It may not work correctly on cryptoglance, but I can look into this and follow up in about ~1 week
