The Cure53 audit is a real credibility marker, and the broader vision is ambitious: an encrypted, self-sovereign storage and app platform with calendar as one piece. That breadth is also the caution, since it’s a younger, less mainstream project and the calendar isn’t a polished standalone the way dedicated tools are. Worth a look if its decentralized-storage philosophy appeals to you. If you simply want a dependable encrypted calendar today, more focused options are a safer bet.
