Unfortunatelly Google got rid of it :( you have to parse it yourself: https://stackoverflow.com/questions/72632982/how-to-get-freetrialperiod-of-subscribtion-from-productdetails

The problem is that in AndroidExtras there is only one OfferDetails with one Pricing Plan, which is the length of subscription.

Do you mean I need to use native API to retrieve product details?

@jamesmontemagno , thanks, now I got it. Google doesn't send information about trial offer if user is not eligible for it. So, basically, there is no way to get trial length is user has already purchased a subscription
