Real-time collaboration
Everyone sees the same events — at the same time.
Real-time subscriptions on events and sub-calendars. Change an event and everyone else sees it without a reload. Optimistic UI with conflict resolution on the server.
02
Drag & drop
Move events with a single grab.
Move or extend events directly in month, week and day views. Recurring events as RFC-5545 RRULE — grid-aware expansion so edits to one instance don’t break the series.
03
Hybrid auth
Accounts and viewer links side by side.
Email login for members, optionally role-based (admin · editor · viewer). For externals: 20-character token links at /c/[token], optionally password-protected. Permission model directly in Appwrite, sensitive mutations via Nuxt server routes.
04
Fully GDPR
Backend in Germany, no trackers.
Appwrite self-hosted in Nuremberg. Locally hosted fonts (no Google CDN), no external trackers, TLS 1.3, data encrypted at rest. Account deletion and iCal export are built in, not bolted on.
