Kalender-Sync: Closed Beta Launched

After months of intense development, it’s here: Kalender-Sync enters its closed beta phase.

What is Kalender-Sync?

Kalender-Sync solves a problem almost everyone knows: you use Outlook for work, Google Calendar privately, and maybe an Apple calendar too — and lose track. Kalender-Sync connects these calendars and keeps them automatically in sync.

What the Beta Offers

  • Google Calendar + Microsoft Outlook: Bidirectional synchronization via OAuth
  • Apple CalDAV: Connection via app-specific passwords
  • iCal Feeds: Import of read-only calendars (university schedules, holidays, etc.)
  • Delta-Sync: Efficient incremental updates instead of full sync
  • Encryption: All credentials stored encrypted with ChaCha20-Poly1305

Next Steps

The beta phase will be used to collect feedback and test stability under real conditions. Also planned:

  • Extended configuration options (filters, time windows)
  • Team calendar support
  • Mobile-optimized web app
