Google Calendar became the default way a team finds a free slot, and the shared availability view is what makes migrating painful, not the events themselves. It is free with a Google account. Calendars live with Google LLC in the United States, and every invitation hands it the attendee list by design.

Why choose Calendar.online over Google Calendar?
The decisive argument is data jurisdiction. Google Calendar is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Calendar.online removes that overhead. As a Germany-based provider, it operates under EU GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
