Good day all

I want to know your thoughts on the safety of the lightning network. I would like some consolation and clear up some misunderstandings.
If I sent a lightning network transactions off-chain and it is confirmed, what is there to stop me sending the on-chain transaction to another wallet I own. When the lightning network channel is closed, then it is no longer available?
Sorry if this sounds stupid

One thing is sure: Nothing is safe online.
