We know the chain origin and final lightning destination in Chain -> Lightning Swaps. We do *not* know the origin in Lightning -> Chain swaps but, the chain destination. We always know amounts.

Publicly, privacy is not too bad with confidential transactions hiding asset and amounts on Liquid (but not tx graph), and with Taproot Swaps it's additionally pretty tough to tell that a tx was part of a swap.

Will start a FAQ section in docs with this as we get this question a lot. Thanks for asking and pushing for transparency!
