OneCal Alternative — GDPR-Compliant & Simple

Many calendar tools promise to tame your scheduling chaos, but few meet the strict data protection requirements that European companies face. If you’re juggling Outlook, Google, and Apple calendars but don’t want your data leaving the EU, you’re in the right place.

Why OneCal Isn’t Ideal for European Teams

OneCal offers a solid interface, but there are three hurdles:

  • Data transfer to the US — problematic under GDPR.
  • Manual setup — no true background synchronization.
  • New app required — extra overhead for you and your team.

The Secure Alternative — No New App Needed

Our solution runs in the background and connects your calendars right where you already use them. No new interface, no new app — just automatic synchronization of your availability.

Benefits at a Glance

  • GDPR-compliant: Your data stays on European servers.
  • No setup stress: Connect once, done.
  • Zero app overload: Stay with Outlook, Google, or Apple.

Example: Freelancer with Two Calendars

Lisa is a freelancer. Her client meetings are in Google Calendar, her personal appointments in Apple. She used to have constant scheduling conflicts — until she started using our sync. Now her calendars automatically block each other — no double maintenance required.
