How do I figure out whether user has rated my game on play store/app store?

Hi,

I was playing with an idea:- user will rate my game on play store/app store and in return a portion of the game will be unlocked.

Is there any way to detect whether user has rated my game or not?

Thanks in advance

I don't think it's possible. Also, it's a violation of Google Play policy, possibly AppStore too:

Ya,you are right.It may be illegal

Iirc in the past when I've seen 'incentivized' ratings, those games didn't actually confirm if a rating was left or not. I recall getting the reward just for clicking the link and going back.
