CBaaS – Calendar Blocking as a Service
Keep multiple calendars in sync by automatically blocking time — without copying meetings, sharing details, or installing another app.
What this looks like in practice
Busy time from one calendar is reflected as blocked time in another. Most calendar sharing applications show only *you* events and meetings, pulled from your multiple calendars. But usally people from an organization can see only one of your calendars. Thus, a proper sync on each calendar works as the best solution to avoid being double booked.
Original calendar with meetings and commitments
Second calendar before any blocking is applied
Busy time converted into blocked slots
Calendars remain aligned without sharing event details
Privacy-first by design
You only provide an ICS link. The system reads time slots only. Meeting names, invitees, locations, and descriptions are never accessed or stored.
Think of it as a calendar that shows availability — not information.
