For ChatGPT, they're under legal obligation not to delete chats for a period of time.

In particular:

> The New York Times is demanding that we retain even deleted ChatGPT chats and API content that would typically be automatically removed from our systems within 30 days.

> ...

> This data is not automatically shared with The New York Times or anyone else. It’s locked under a separate legal hold, meaning it’s securely stored and can only be accessed under strict legal protocols.

> ...

> Right now, the court order forces us to retain consumer ChatGPT and API content going forward. That said, we are actively challenging the order, and if we are successful, we’ll resume our standard data retention practices.
