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 expiration has nothing to do with inactivity. Even if you log in to Neeto every day, 30 days after the first login you will be logged out and you will be asked to log in again. Once you log in, then you are good for the next 30 days.
