GDPR-Compliant Calendar Sync for EU Teams
Kalender-Sync launched on IH as a GDPR-compliant calendar sync tool hosted on Hetzner in Germany, with data stored in the EU and no US company involvement. The opportunity is broader: EU companies need calendar, scheduling, and collaboration tools that guarantee EU data residency, a wedge that grows as GDPR enforcement intensifies.
Problem Statement
EU companies using Google Calendar or Microsoft 365 sync tools send personal data (meeting attendees, topics, locations) through US servers, creating GDPR compliance risks. Most scheduling tools (Calendly, Cal.com) host data in the US. Companies subject to strict GDPR interpretation (healthcare, legal, government contractors) cannot use these tools without data processing agreements that may not withstand regulatory scrutiny.
The Idea
A GDPR-native calendar synchronization tool that syncs Google and Microsoft calendars across teams while keeping all data within EU borders, targeting EU companies that cannot use US-hosted scheduling tools due to data residency requirements.
Why Now
GDPR enforcement is intensifying with larger fines and stricter interpretation of data transfers. The EU-US Data Privacy Framework remains contested. EU companies are proactively seeking EU-hosted alternatives to US SaaS tools. Kalender-Sync proved the concept with 6 testers in closed beta. Calendar data contains personal information (attendee names, meeting topics) that triggers GDPR compliance.
Target User
IT administrators and data protection officers at EU companies in regulated industries
Target Market
EU companies in healthcare, legal, finance, and government contracting with strict data residency requirements
