Kalender-Sync

Kalender Sync gives Claude privacy-first access to your calendars across providers: Google, Microsoft/Outlook, Apple iCloud, GMX, WEB.DE and other CalDAV services. You choose exactly which calendars Claude can see and how much detail per calendar (busy-only, title and time, or full details). Check availability, search and manage events across all your accounts. Events are read live from the provider, never stored. GDPR-compliant, made and hosted in Germany.
