Not that I've seen. I'm lead to believe that the expiration date is one year from when you last complete a survey. Regardless of how much you have in your wallet already, and when they were accumulated. e.g. $1 earned on 01/01/17 - expiration date: 01/01/18 $1 earned on 01/02/17 - new expiration date: 01/02/18 when $2 will expire. You won't lose $1 on 01/01/18. Google's account settings changed some time in the past. You used to be able to see the tally of your earnings, but I can't find it now. At least on desktop. I haven't tried looking through my phone app.
