Hi timo,
While we wait until you to do this I have been trying to find a way of syncing my Windows version of Diarium because since Apple's "Advanced Data Protection" and with the addition of physical security keys to my account (which we have discussed here ) it has rendered my windows version of Diarium useless for me. I even tried to use WebDAV using my own NAS but as luck would have it, my NAS provider released an update disabling WebDAV on my device! we talked about that here
Is there a way I can use my Windows PC to sync Diarium? I managed to create a Mapped Network Drive to to my NAS and wondered if I could somehow get Diarium to use the mapped network drive? Another option I thought of was if you could add support for Cryptomator?
I used to use my PC for 90% of my journaling so I really miss using it, but obviously, privacy issues has forced me to stop syncing on windows.
