i really don't know, there are no good options for mobile. there isn't a steam for android. google play doesn't allow adult content...
can't sell on itch cause they took the option from a bunch of devs a while ago... yeah idk
it's always so surprising to me how there are still people who don't know how poorly patreon treats their creators 😭
tldr: they have banned hundreds if not thousands of creators. a big notable example is koahri: they forced her to delete sfw images of her character that she posted way before she even joined patreon. koahri complied, but then patreon banned her anyway. there are many many such cases. i want nothing to do with that company
