Let's say that you log in to neeto someday. 30 days from that day, your login session will expire, and you will be asked to log in again. This is to ensure the security of your account.
This "login session expiry" has nothing to do with inactivity. Even if you log in to neeto every day then 30 days after the first login you will be logged out and you would be asked to log in again. Once you login then you are good for the next 30 days.
