How Kalender Sync helps your project life

No double-booking costs you money anymore

Blocked times appear automatically in every calendar, in real time. You never give the same slot away twice – and you stay reliable for every client.

All calendars in one place

Google, Outlook, Apple iCloud and more – finally all your project and personal calendars come together. You see at a glance when you're really free.

GDPR compliant Made & hosted in Germany

For yourself or for sharing

Share free time with clients without showing private appointments. Per sync, you decide whether only "busy" or details are visible – and which label a blocker appears with.

Real-time sync without manual upkeep

Changes appear instantly in every connected calendar – no follow-ups, no updates. Set up once, it just runs in the background.
