How Kalender Sync helps across mandates

Real-time across every mandate

Connect the calendars of your companies and mandates across providers. Kalender Sync keeps them in sync in real time – whether Google, Outlook or iCloud.

Confidentiality by default

You decide that sensitive appointments only appear as "busy" – no title, no details. Optionally even with your own label for blockers. GDPR-compliant and hosted in Germany.

GDPR compliant Made & hosted in Germany

Your office plans without risk

Because every calendar shows the same truth, your team can confidently plan for you – no fear of overlaps.

Every role in a single picture

An appointment in one company automatically blocks the slot in every other – instantly and without manual action. So no conflicts between your roles.
