How Kalender Sync helps with client work

No more double-bookings during peak season

Whether year-end closing or deadline rush: Kalender Sync keeps all your calendars in sync in real time. Blocked times appear everywhere automatically – you never double-book again.

Client data stays confidential

Built in Munich, made for Europe. Your data is processed GDPR-compliant and hosted on servers in Germany.

GDPR compliant Made & hosted in Germany

Share availability without extra effort

Share your free time with clients or your team, without anyone seeing into your calendar. The recipient only sees when you're available – not what fills that time.

Personal and firm cleanly separated

Sync one-way or both ways and keep work and personal calendars clearly apart – without constantly transferring appointments by hand.

Ready for more time with clients instead of your calendar?
