I've used organicmaps for a while. but it needs a way to sync bookmarks. I bookmark places like a good restaurant, parking places, fuel stations, stores, roadside attractions to places I've been to. But without a cloud sync(preferably self-hosted nextcloud), I always fear I'm going to lose my bookmarks. There was another open-source maps.me fork before Organic maps and it lost maps/bookmarks with certain updates and became abandoned.[1]

With file access limitation with recent android versions, I can't just use foldersync or syncthing on the bookmarks.
