Why is there no cloud synchronization feature built into KeePassXC?
Cloud synchronization with Dropbox, Google Drive, OneDrive, ownCloud, Nextcloud etc. can be easily accomplished by simply storing your KeePassXC database inside your shared cloud folder and letting your synchronization service of choice do the rest. We prefer this approach, because it is simple, not tied to a specific cloud provider and keeps the complexity of our code low.
