Very Good Calendar Sync

Very Good Calendar Sync is a macOS app that synchronizes your calendars across accounts—without compromising your privacy. No third-party servers, no data collection, no account linking. Just your Mac talking directly to your calendars.

Key features include:

• Clone or Redact – Share your availability without sharing details. Clone events with full info or redact them to show only that you're busy.
• Stays Out of the Way – Runs quietly in your menu bar. Set up syncs once and forget about it; it updates automatically whenever calendars change.
• No Accounts to Link – Your Google, Microsoft, and Apple credentials stay safe under macOS' Internet Accounts. No logins on third-party websites.
• Flexible Filtering – Sync only weekdays, weekends, or specific days. Set a time range to limit syncing to work hours.
• Built into macOS – Works directly with Calendar.app. No extra apps to install, no connections to configure.
• No Middleman – The app runs entirely on your Mac. No servers, no data collection, no analytics on your calendar.

Perfect for consultants, freelancers, employees with multiple calendars, and cross-functional teams. Works with Google Calendar, Microsoft Outlook, Apple iCloud, and any CalDAV account. Your first sync is free.
