I love #nextcloud. Its the best thing ever if you don't trust anyone but still want to have synced files. I've been using it for my calendars (well, and files of course) for a long time now. Works perfectly.
Now I switched to the #dissenter browser a while ago, and missed having my bookmarks synced. Nextcloud has the solution, of course. Floccus + bookmarks, and problem solved without using any 3rd party storage.
