Can the DBs get merged or are they subject to conflict race conditions?
A years ago experienced hassle and data loss (not of passwords) due to local-first sync solutions such that I’m very wary of them now.
Race condition? In the context of my usage that's not possible and I'm only the only user, and am accessing the data on one device at a time. Even less so since I'm essentially using sneakernet rather than cloud storage for "sync".
