What Makes a Calendar Tool GDPR-Compliant?
Not all 'GDPR-compliant' claims are equal. Calendly meets compliance through paperwork: Standard Contractual Clauses and transfer impact assessments. That's legal gymnastics, not architectural safety.
Here are the five things that actually matter:
1. Data Residency and Hosting. Store everything in the EU. Germany and Finland are the safest choices. US hosting requires complex data transfer agreements that regulators scrutinize. EU hosting eliminates the question.
2. Data Processing Agreement. Article 28-compliant DPA outlines who controls data (you) and who processes it (your vendor). It's a legal requirement. Most US tools offer it as optional paperwork. European tools include it by default.
3. No Tracking or Hidden Cookies. Booking pages should not deploy third-party analytics or ad trackers by default. EU GDPR-compliant tools ship privacy-first. Calendly ships with cookies for upsell and tracking.
4. User Rights Built In. Attendees need easy ways to access, correct, export, or delete their data. Calendly requires support tickets. Transparent tools make it self-service.
5. Calendar Sync Transparency. When you connect Google Calendar or Outlook, the tool should access your availability only, not read attendee details. This is the fine print nobody talks about.
Cal.com checks all five boxes. Calendly checks one (hosting, through legal workarounds).

Frequently Asked Questions
Switching from Calendly? Here's what you need to know.
Cal.com is built with privacy-first architecture: it stores all data in EU data centers, includes a standard Data Processing Agreement by default, and uses end-to-end encryption. Calendly, by contrast, is US-hosted and relies on Standard Contractual Clauses and transfer impact assessments, paperwork-based compliance rather than architectural safety. When you host Cal.com on Opsily, every event, attendee detail, and integration stays in ISO 27001-certified German infrastructure with zero US access.
