Why Teams Across Europe Look for a Calendly Alternative
Calendly is headquartered in the United States, and its current DPA provides for processing of personal data in the United States and other jurisdictions. For legal firms, healthcare providers, HR departments, and public sector organizations in the EU, cross-border transfers and US jurisdictional considerations require Transfer Impact Assessments (TIAs) and risk scrutiny from Data Protection Officers (DPOs).
Beyond jurisdiction, traditional scheduling software enforces rigid per-seat pricing. When HR teams conduct candidate interviews with hiring managers or subject matter experts, many tools force you to buy full licenses for every internal attendee—even if they only connect their calendar to share availability and never create their own booking links.
How Kalendarius Solves European Scheduling Challenges
Kalendarius operates on 100% EU-sovereign infrastructure hosted in ISO 27001-certified European data centers. No attendee data or calendar metadata leaves the European Economic Area. Every organization receives a signed Data Processing Agreement (DPA) incorporating standard contractual safeguards and Article 9 readiness for special categories of personal data.
Our team-friendly pricing ensures only organizers who create booking links pay. Internal panel members, interviewers, and team participants connect their Google or Microsoft calendars completely free of charge, keeping software budgets predictable as your organization scales.
Seamless Google Calendar & Microsoft 365 Synchronization
Kalendarius integrates bi-directionally with both Google Calendar (Google Workspace) and Microsoft 365 / Outlook. Real-time availability checking prevents double bookings, while automatic buffer times, timezone conversion, and custom reminder notifications deliver a frictionless experience for both hosts and guests.
Whether you need 1-on-1 discovery calls, collective panel interviews, or round-robin lead distribution across sales reps, Kalendarius automates scheduling without compromising European data privacy.
