if you are asking about the insurance available through IDEA here, then the answer is: Yes, Yes, and Yes.
Before the end of the insurance period of one year, you will receive communication from them about renewing your policy.
The policy I got through this site is valid for a year.
This is my second time using them. The first time, they did NOT send me a reminder email that my renewal was due. That was actually fine because I went from a contracting position to employee at another place. This time around, I will keep better track of my own policy, since I didn’t get communication last time.
