Great questions! I thought a lot about those at the time, I didn't felt comfortable sitting on a pile of data waiting for an attacker to try get it. So this is what I did:

Once I decided I was going to kill the project, I removed the option to become a paying customer to not get more, waited for the last of my paying customers period to finish (it was a yearly subscription). And released an update that made the app work strictly locally, user data does not reach my server (edit: there is no server anymore) and stays in the user's browser (it works like that now).

Kept the data for a couple of weeks in case anyone wanted to recover it to help them use it with in the new "local" version, but enventually no one did, so finally I deleted my db. So right now I have no access whatsoever to that data.
