Effortless scheduling, made for Europe.

The scheduling platform built for EU enterprises. Connect Google & Microsoft calendars, share booking links, and let your team focus on the conversations that matter — all on EU-sovereign infrastructure.

No credit card required · Free up to 15 meetings/month

Built for European compliance from day one

Kalendarius is designed from the ground up to meet European legal requirements — so compliance is part of the foundation, ready when you are.

EU-Sovereign & GDPR-Native

Your data lives on European servers. Trusted by healthcare providers, law firms, and public administration with strict data residency requirements.

Friendly Pricing for Teams

Only HR admins pay. Internal staff who attend panels connect their calendars for free — so your costs stay predictable as your team grows.

Instant Availability Engine

Real-time Google & Microsoft calendar sync. Atomic slot reservation keeps every booking accurate, even under load.

Multi-Timezone & Multi-Host

Schedule panel interviews across time zones with ease. The system intersects every participant's availability automatically.

Share from your inbox

The Kalendarius extension puts a Schedule button right inside Gmail and Outlook, so you can share your booking link without leaving the email you're writing.

Works where you write

A Schedule button appears in the Gmail and Outlook Web compose bar — including Microsoft 365 work accounts.

Every event type, one click

Pick any of your booking links — a 15-minute intro or a 30-minute consultation — and copy it into your email instantly.

Private by design

Minimal permissions, no tracking, and your emails are never read. Just like the rest of Kalendarius.

See it in action

From calendar sync to confirmed booking in three simple steps — no back-and-forth emails required.

Connect your calendar

Sync Google or Microsoft Calendar in seconds — we calculate your real, live availability automatically.

Share your booking link

Guests pick a time that already works for you — share your link anywhere, even straight from Gmail or Outlook with our extension.

Get confirmed automatically

The meeting lands on both calendars instantly, with confirmations and reminders sent for you.

Pricing that grows with you

Anyone on your team can connect their calendar for free. Only people who create booking links pay — so cost scales with the work, not your headcount.

Frequently asked questions

Everything you need to know before you switch.

Where is my data actually stored?

On EU-sovereign infrastructure, GDPR-native by design. Special-category data (health, HR) covered under GDPR Article 9 is supported for the most sensitive workflows — healthcare, legal, and public administration included.

Which calendars does Kalendarius sync with?

Google Calendar and Microsoft Calendar, in real time. Atomic slot reservation prevents double-bookings even when several people are booking at once.

How does pricing work for a team?

Only the organizers who create booking links pay. Coworkers who just need their calendar checked for availability — panel interviewers, for example — join and connect their calendar for free.

Is there a free plan, and do I need a credit card?

Personale is free forever — 15 meetings a month, no credit card required. Every paid tier adds a 14-day free trial with no charge until it ends.

Can I schedule across time zones or with multiple hosts?

Yes. Kalendarius supports multi-timezone and multi-host scheduling, automatically intersecting every participant's availability for panel interviews.
