How paid episodes work, and what happens to the coins.
Some episodes are free and some cost coins. The player shows the price before you spend anything, and an episode you unlock stays unlocked on your account — on the website and in the app.
Coins come from packages in the Store, and free coins can be earned by watching ads (there is a daily limit). Bonus coins are spent before purchased ones.
Part of what you spend goes to the creator who made the episode.
