What you write, and what the AI writes
What you write is yours: your characters, what you type, and the worlds you build. You give us permission to store it, show it where the game shows it (to other players in the same place, on the adventurers layer, on a world's public page if its builder publishes one), and send it to AI providers to run the game. That permission ends when you delete it, except where it is part of other people's shared scenes or someone else's world.
The AI's writing is fiction. It can be wrong, inconsistent, or unpleasant, and it is never advice. You may use what the storyteller wrote for your own play however you like, within the law. Where the engine and the story disagree, the engine's record (health, items, money, the map) is what counts.
