Number of point is saved in HPA_usermeta but cann't find price that is assigned for each point in the backend

I am using the free version of "Points and Rewards for WooCommerce" plugin in my shopping site that I developed using WordPress. I assigned a price for every point so users can apply it during the checkout to get discount.

At the same time, I built a mobile application and I connected with the same database of the site. Number of point is saved in HPA_usermeta but cannot find price that is assigned for each point. So, I was wondering of how I can find this value.

The following photo shows HPA_usermeta table:
