Hi. I am not familiar with freemium business models. But maybe you could make one non-consumable product out of each of, let's say, four campaigns in a year. So for 2021 four products: PQ01-2021, PQ02-2021, ... and for 2022 four products: PQ01-2022, PQ02-2022, ... Once the sales period for a campaign has expired, you no longer offer the associated product by removing the product from the store. Anyone who has purchased the product can participate in that exact campaign.
