Well, shame on me. I should have read the details before paying the price. I don’t fell that DayOne Synce is private enough to sync my files through it and this version does not support other sync servers. From my point of view, they should not have released a version without this features in respect to DayOne Classic user like me. I won’t be able to use this version until they add other sync engines.
