Hey, that's a valid concern. I've started building a CLI tool that will allow you to setup recurring lightning payments from your own node. There won't be any approval though - you approve it by setting it up. But you gave me an idea about a notification when a payment happens.

Question about subscription payments built on top of lightning

I would like to approve every single payment. Otherwise i lose track of where my money go. Even now I don't use subscription services for this reason. And when I do I pay and cancel immediately (and get asked why I cancel).
