What is OneCal?

Juggling multiple calendars from Google, Outlook, and iCloud can be a scheduling nightmare—double bookings, missed meetings, and constant manual updates. OneCal solves this by syncing all your calendars in real time, so everything stays up to date automatically across platforms. Whether you're managing work, personal life, or client appointments, OneCal keeps your schedule unified and conflict-free.

With OneCal, you get more than just syncing: share easy booking links, control what details appear on each calendar for privacy, and manage everything from one clean, mobile-friendly interface. Trusted by over 5,000 professionals—from freelancers to executives—it’s the simple way to bring order to calendar chaos without compromising security.

What are the features of OneCal?

• Real-Time Multi-Way Calendar Sync

  Instantly sync events between Google Calendar, Outlook, and iCloud—changes reflect across all connected calendars as they happen (iCloud updates may take up to 10 minutes).
• Privacy-Focused Sync Controls

  Choose exactly what info syncs—hide event titles, limit details, or exclude certain events—so your work calendar stays professional while your personal one stays private.
• Custom Scheduling Links

  Create individual or team booking links in minutes, letting others schedule time with you without back-and-forth emails.
• Unified Calendar View

  Manage all your calendars in one place—create, edit, RSVP, or join meetings from a single, intuitive interface on web or mobile.
• Zero Data Storage Policy

  OneCal never stores, analyzes, or sells your calendar data. Events are synced securely via OAuth2, and only minimal necessary permissions are requested.
• Team & Multi-Organization Support

  Sync calendars across different companies or Gmail accounts, and upgrade to team plans for organization-wide coordination.
