Technically, all the messages are stored in our DB (anything that's visible in our dashboard is stored in our DB), so if we wanted to, we could see the messages flowing through Omnara. If you delete a chat instance, the messages are deleted immediately, no soft deleting.

But yes this is a good point, it's a big reason we open sourced our backend. We've thought about doing client side encryption before sending messages to our servers, but that probably won't be implemented in the near-term.
